=== Safety Notes and Warnings === <!--T:1-->

<!--T:2-->
==== Important: ====
Remember that your engine is not a „toy“, but a highly efficient internal- -combustion machine whose power is capable of harming you, or others, if it is misused. Before attempting to operate your engine, please read through these instructions to familiarize yourself with the operations and features of this technical, fully operational model engine. Please read through the entire manual before operating this engine. Pay particular attention to the Safety Instructions and Warnings section of the manual. Your new KAVAN engine will give you dependable performance and will be a source of satisfaction and pleasure if you follow these instructions as to the engine‘s proper and safe use. Do not let pleasure turn into injury and/ or tragedy! You alone are responsible for the safe operation of your engine, so act sensibly and with care at all times. This engine is a precision built machine whose power is capable of causing harm to you and others if abused, misused, or if you fail to observe proper safety precautions. As owner, you, alone, are responsible for the safe operation of your engine, so act with discretion and care at all times.

<!--T:3-->
==== Always Remember: ====
# Keep spectators, especially small children, who can be hurt when the engine is running at least 5-6 metres (20 feet) away from the operating engine. NOBODY should (including yourself) should be found in the plane of the rotating propeller! 
# Mount the engine securely in the plane, or on a proper engine test stand using high quality steel hex cap screws, washers and locknuts. Follow the mounting recommendations on the airplane‘s plan and/or instruction manual, or in the test stand described in the directions. DO NOT clamp this engine into a vice! 
# Use the correct size propeller and follow the recommended mounting procedures. Follow this instruction manual, the building plan/kit instruction manual; ask an experienced modeller or skilled model shop personnel if in doubts. 
# Install your propeller properly (looking from the cockpit of your model, the propeller of an engine installed in the nose rotates clockwise, looking from the front of the model it rotates counter clockwise). Use a proper wrench to tighten the propeller nut. Do NOT use pliers. Four stroke engines and large two stroke ones should use special safety locking propeller nuts. 
# Never touch, or allow any object to come into contact with, the rotating propeller and do not crouch over the engine when it is running. 
# Beware of the prop, protect your fingers. When hand cranking your engine, always us the „chicken stick“ (available in model hobby shops) or strong leather glove. Preferably, use an electric starter. 
# After starting the engine, carry out any needle-valve readjustments from a safe position behind the rotating propeller
# To stop your engine, adjust the throttle linkage so that the engine stops when the throttle stick and trim lever on the transmitter are fully retarded. Alternatively, the engine may be stopped by cutting off the fuel supply. Never try to stop the engine physically. 
# Discard any propeller which has become split, cracked, nicked or otherwise rendered unsafe. Never attempt to repair such a propeller: destroy it. Do not modify a propeller in any way. Also, check the tightness of all the screws and nuts regularly and frequently. 
# If you have to carry the model to the take-off point with the engine running, be especially cautious. Keep the propeller pointed away from you and walk well clear of spectators. 
# Do not fly your model near or under power lines. 

<!--T:14-->
==== Safety Tips ====
<ol style="list-style-type:upper-alpha">
<li> The wearing of safety glasses is strongly recommended.</li> 
<li> Do not start your engine in an area containing loose gravel or sand. The propeller may throw such material in your face and eyes and cause injury.</li><li>  Take care that loose clothing (ties, shirt sleeves, scarves, etc.) do not come into contact with the propeller. Do not carry loose objects (such as pencils, screwdrivers, etc.) in a shirt pocket from where they could fall through the propeller arc. 
</li><li>  Take care that the glow plug clip or battery leads do not come into contact with the propeller. 
</li><li> If you install a spinner, make sure that the slots for the propeller blades do not touch the blade roots and weaken them.</li></ol>

<!--T:19-->
==== Warnings ====
# Model engine fuel is poisonous. Do not allow it to come into contact with the eyes or mouth. Always store it in a clearly marked container and out of the reach of children. 
# Model engine fuel is also highly flammable. Keep it away from open flame, excessive heat, sources of sparks, or anything else which might ignite it. Do not smoke or allow anyone else to smoke, near to it. 
# Model engines generate considerable heat. Do not touch any part of your engine until it has cooled. 
# Never operate your engine in an enclosed space. Model engines, like automobile engines, exhaust deadly carbon-monoxide. Run your engine only in an open area. 
# Remember: Operating any model requires experience and constant attention to safety rules. Model airplanes, boats or cars have a lot of energy that can cause serious personal injury or significant property damage. 

<!--T:24-->
'''Always proceed with caution!!''' 

<!--T:25-->
'''If you are a beginner, ask for help and advice from an experienced modeller!''' 

<!--T:26-->
'''Before trying to start the engine for the first time, carefully read the instructions and safety rules!''' 

<!--T:27-->
=== For Beginners… ===
In internal combustion (IC) engines with a glow plug, the fuel mixture is ignited in the engine cylinder by a spark plug located in the centre of the cylinder head. To start the whole process, you need to have 1.2-1.5V glow battery (or another source, such as a Power Panel designed for this purpose) connected to the glow plug filament. The glow source must be able to provide such a current that the spark plug glows with a bright orange light, which you will see if you look into the cylinder space with the muffler removed, or if you carefully shield the spark plug placed in the glow plug terminal with your hand from the light. The ignition of the fuel mixture is caused by the high temperature of the filament and the catalytic effect of the platinum filament on the fuel. Once the engine starts, it is able to operate without further additional heating as long as it has enough fuel (and air).

<!--T:28-->
=== Fuel ===
KAVAN engines can be operated on standard fuel for model engines with glow plugs containing 20% of castor oil. When using fuel with castor oil, it is usually more appropriate to operate larger two-stroke engines (over 7.5 cc/0.45 cu inch) after running-in with fuel with an oil content reduced to 15%. It is also possible to use fuels containing synthetic oil or a mixture of synthetic and castor oil. The addition of nitromethane is not absolutely necessary (even for four-stroke engines), but in any case it will increase performance, idling reliability and transitions to higher speeds and simplify engine adjustment. For four-stroke engines (and large two-stroke engines) it is advisable to use fuel with the addition of nitromethane (5-15%). KAVAN Europe s.r.o. offers a wide variety of glow fuels tailored to different needs of two and four stroke engines.

<!--T:29-->
=== Glow Plug ===
The choice of glow plug depends on the type of engine (two-stroke/four- -stroke), engine displacement and fuel used. KAVAN supplies the multi-purpose GP-1 glow plug for its engines, which is very suitable for both two- and four-stroke engines. If you decide to try other spark plugs, follow the following recommendations: Two-stroke engines up to 3.5 ccm (.21 cu inch) require a warm or medium spark plug (O.S. MAX No.6 (former A3), KAVAN Premium No.1 etc.), 3.5-10 ccm (.21-.60) engines then a cold one (O.S. MAX No.8, KAVAN Premium No.3), engines over 10 ccm (.60) run well on super cold glow plugs or glow plugs with a bridge (O.S. MAX No.10 (former A5). Four-stroke engines require special long glow plugs (O.S. MAX F, KAVAN Premium 4T etc.) In practice, start with the basic recommended type, over time you can try others to achieve optimal performance and reliable operation.

<!--T:30-->
=== Preparing the Engine for Operation ===
KAVAN engines do not require any special procedure requiring special preparations. We recommend that you simply flush the engines with kerosene before starting them for the first time to remove any possible preservative residues. However, do not flush the carburettor with kerosene, as this could damage the silicone sealing rings. 

<!--T:31-->
'''Flushing two-stroke engines:''' pour a small amount of kerosene into the combustion chamber through the spark plug hole and rotate the crankshaft – ATTENTION – ONLY AT BOTTOM DEAD CENTER - NOT THROUGH TOP DEAD CENTER. Pour out the kerosene, repeat 2-3 times. Then you can screw in the spark plug and carefully turn the engine past top dead centre again with a small amount of kerosene. Finally, unscrew the spark plug again and pour out the kerosene. We repeat once again – the ABC two-stroke must not be rotated past top dead centre without a spark plug screwed in! 

<!--T:32-->
'''Flushing four-stroke engines:''' flush again with kerosene, which we pour through the spark plug hole and a small amount into the drip nipple on the crankcase. Carefully turn the engine over, pour out the kerosene and repeat 2-3 times.

<!--T:33-->
=== Starting the Engine ===
Although running-in on a stand („bench top“) is not necessary for KAVAN engines, such a short test run can still be useful for getting familiar with the starting and operating of the engine. The engine should be mounted to a solid hardwood or plywood test bed with a U-shaped cut-out corresponding in width to the width of the engine crankcase between the mounting lugs. Use steel bolts at least 25 mm long with washers and locking nuts. The screw thread always corresponds to the maximum diameter of the bolt that can be threaded through the holes in the engine lugs. The test bed should be fixed to the workbench as tightly as possible. Always leave enough free space for the propeller. Ensure good access to the needles, glow plug, etc. Clean up around the engine so that small objects cannot get into the propeller due to vibrations or blown by the air flow from the propeller. 

<!--T:34-->
{{Note|type=error|text='''Caution:''' The workshop must be well ventilated, otherwise there is a risk of carbon monoxide poisoning from the exhaust gases.}} 
* The tank containing the recommended fuel must be secured so that the fuel outlet is at the same height as the needle-valve on the carburettor. Prepare (do not connect yet) a glow plug heater - a Power Panel with 12V lead-acid battery, a compact glow plug heater (with 1.2-1.5V battery with a capacity of at least 1700 mAh etc. 
* Fasten the propeller so that the engine piston reaches top dead centre (TDC) at the “two o’clock” position. Select the propeller diameter and pitch according to the table in this manual. 
* Set the needle-valve 1-1/2 (one and a half) turns from the fully closed position. Set the throttle lever to the 1/3 open position with your radio. 
* Prime (draw fuel into) the engine by turning the propeller counter clockwise several times, while closing the carburettor air intake with your finger. (You can also inject a few drops of fuel with a syringe above the piston if you have removed the muffler or glow plug - this can be useful for a beginner who has not yet mastered the correct „swing“ of the propeller when starting the engine for the first time. Once the engine is properly run in, it does not require any such thing. 
* If the engine is built into the model, you can achieve the same effect by turning the model „upside down“ for a few seconds. Only briefly - be careful not to flood the engine.) 
* If you are using an electric starter, do not choke the carburettor air intake - otherwise an excessive amount of fuel will be sucked in that could hydro-lock the engine. 
* Turn the propeller once to remove any excess fuel and connect the glow plug heater. A few vigorous turns of the propeller should now cause the engine to start, even if only for a short time. 
* Adjusting the needle-valve (1) - slowly open the throttle fully, and then slowly close the needle until the engine sound starts to change (from a high pitch to a lower pitch). Disconnect the glow plug heater. If the engine stalls, close the needle a little more (about 30 degrees) and start the engine again. 
* Adjusting the needle-valve (2) - Close the needle by 10-15 degrees and wait a moment for the speed to change. After the speed increases, repeat the procedure (always with a small delay) until the engine speed does not change when the needle is closed. 
* If the engine does not start at all, check to see if the glow plug is glowing. If the engine starts, runs for a few seconds, and then stalls, open the main needle 1/2 turn, prime the fuel again, and start again. Immediately after starting, when the engine is running on the fuel you primed, you should see a column of fuel being drawn into the engine through the fuel line. Remember, if the glow plug and glow plug heater are good and the engine has fuel, it should start, even if only for a moment.

<!--T:45-->
=== Carburettor Adjustment ===
All KAVAN RC engines are equipped with a carburettor featuring two mixture controls characterized by easy adjustment, high reliability, very low idle speed in combination with very good transitions to high speeds. 

<!--T:46-->
==== Carburettor Adjustment Controls ====
# Needle-valve (adjusts maximum engine speed) 
# Mixture control valve (adjusts the richness of the mixture at idle speed) 
# Idle stop screw (adjusts the extreme position of the carburettor rotor) 

<!--T:49-->
===== Needle-valve =====
After being set to provide maximum speed at full throttle, it determines the basic air/fuel mixture ratio. The correct mixture at lower speeds is then set automatically.

<!--T:51-->
===== Mixture Control Valve =====
Determines fuel delivery at low and idle speeds to ensure reliable operation when reducing and increasing the throttle. The default mixture control valve position is preset at the factory. Start the engine with this setting and only change it if necessary. 

<!--T:52-->
===== Throttle servo adjustment =====
Idle speed is controlled by the throttle control trim on the transmitter, which allows full control of the speed from idle to maximum speed and engine shutdown by trim. Adjust as follows: with the throttle trim in the down position, adjust the servo deflections so that the carburettor rotor is fully open when the control stick is in the full throttle position and fully closed in the down position. Idle speed is then adjusted by moving the trim as needed. 

<!--T:53-->
===== Restoring the Mixture Control Valve Initial Setting =====
To adjust the carburettor, it is a good idea to have a short piece of clean fuel tubing on hand, through which you will blow air into the carburettor with your mouth. You can use the following procedure to make an initial mixture control valve adjustment. Close the carburettor rotor so that the diameter of the hole is no larger than the thickness of a modeller‘s pin (ca 0.7 mm). Place a piece of clean fuel tubing on the carburettor fuel intake nipple and open the needle-valve 1-1/2 turns from the fully closed position. Now close the carburettor rotor completely and, while blowing gently into the tubing with your mouth, adjust the mixture control valve to a position where air just begins to escape. The correct operating position of the mixture control valve can then be obtained by opening it an additional 1/2 turn. The adjustment is further checked by opening the carburettor rotor while blowing continuously; you should notice a rapid change in airflow as soon as the carburettor is opened about 15 degrees from idle. Do not use the mixture control valve to set the mixture too rich in an attempt to reduce idle speed. Instead, close the carburettor rotor a little more and repeat the mixture control valve adjustment.

<!--T:54-->
=== Running-in ===
All internal combustion engines require special care during the first few starts. Running-in allows the moving parts of the engine to “settle” under the high temperatures and pressures. Since KAVAN engines are manufactured using the latest technology and the highest quality materials, the running-in procedure is very simple. 

==== Idle Adjustment Diagram ==== <!--T:56-->

<!--T:55-->
# Install the propeller specified for your model. Open the needle-valve 1-1/2 turns from the fully closed position and start the engine. Let it run for two or three minutes at the minimum speed at which it will run with a rich mixture.
# Close the needle-valve until the engine is running; let it run for 10 seconds, then open the needle to its original position for another 10 seconds. Repeat this procedure until the tank is used up. 
# Set a reliable idle according to the Idle Adjustment diagram below. 
# Restart, open the needle-valve about 1/2 to 1 turn, and let it run for three or four tanks. 
# During subsequent flights (or engine starts), gradually close the needle- -valve to the optimal position. After six to ten flights, the engine should run reliably at the optimal setting. Do not rush the running-in process - the engine will reward you for this little care with good performance and long term reliable operation. 

<!--T:61-->
==== Mixture Control Valve Fine Setting ====
Start the engine as described above, slowly close the throttle, and set the idle speed. Hold the model in a horizontal position and slowly lift the nose of the model up. 
# If the engine revs up, you need to close the mixture control valve and repeat the procedure until the rpm does not change when the model is raised. 
# If the engine runs irregularly or stalls, open the mixture control valve slightly. Repeat the procedure again until everything is fine. 

<!--T:107-->
{{Note|type=info|text='''Note:'''  The needle-valve and mixture control valve settings are always somewhat cross-affected. If you make a major change in the setting of one needle, you will probably need to fine-tune the other one as well.}}

<!--T:62-->
=== Adjusting Valve Clearance on Four-Stroke Engines ===
The valve clearance is preset by the manufacturer and does not require further adjustment by the user. In normal operation, it is advisable to check the valve clearance regularly - for example, if you regularly fly every weekend, you should check the adjustment approximately every 3-4 months. The procedure for adjusting the clearance is given in the appendix.

=== Troubleshooting Guide === <!--T:63-->

|rowspan="2"|Engine stops when the glow plug heater is disconnected after starting
|Mixture too rich
|Close the needle-valve a little
|-
|Mismatched glow plug and fuel
|Change fuel or glow plug
|}

<!--T:66-->
==== Carburettor Cleanliness ====
The correct functioning of the carburettor directly depends on the cleanliness of the intake mixture. Impurities in the fuel can cause the carburettor nozzle to clog. Therefore: Do not run the engine in dusty conditions. When operating on the ground, protect it from swirling dust in an appropriate manner. Flush the fuel tank with methanol or fresh glow fuel before installation. Place an in-line fuel filter between the engine and the tank. Use a tank filter in the fuel tank or at the fuel pump inlet. Do not leave the fuel tank open unnecessarily. Check the filters and nozzle regularly and clean them as necessary.

<!--T:67-->
=== Engine Maintenance ===
To ensure maximum engine life, reliability and performance, follow these guidelines: 
# Always drain the tank at the end of the flight session. 
# Turn on the glow plug and try to start the engine again to burn off any fuel remaining inside. Repeat as long the engine starts. Remove any fuel residue by cranking the engine for 4-5 seconds while the engine is still hot. 
# Finally, inject „straight“ fuel (containing no nitromethane) into the engine. Crank the engine several times by hand to make sure it turns freely, and then crank the starter for 4-5 seconds to ensure that all friction surfaces are lubricated. If you are using a nitromethane containing fuel, this flushing with non-nitromethane fuel is a very useful habit to eliminate the corrosive effects of incompletely burned fuel residue that would otherwise build up in the engine. 
# This procedure will reduce the risk of starting difficulties caused by internal corrosion after extended periods of storage. Before storing the engine out of operation for a longer period of time, it is advisable to treat the engine with a few drops of After Run oil.

=== Appendix === <!--T:72-->

<!--T:73-->
==== Adjusting the Valve Clearance of KAVAN Four-Stroke Engines ====
The valve clearance is adjusted when the engine is assembled at the factory and does not need to be adjusted in normal operation. However, after a longer engine operation, the performance may decrease (as well as after dismantling or repairing the engine after a model accident) and the clearance adjustment is necessary. For this purpose, you can use the O.S. Engines No. 72200060 set containing two gauges and two hex keys or purchase 0.04 and 0.10 mm feeler gauges and the corresponding tools (2 mm hex key, flat wrench No. 5, small flat screwdriver) from a specialist shop. 

<!--T:74-->
{{Note|type=warn|text='''Attention:''' The valve clearance is to be adjusted only on a cold engine.}} 
# Remove the valve rocker cover after loosening the two socket screws 
# Rotate the engine twice counter clockwise and enjoy the movement of the valves. Continue turning the propeller counter clockwise until you feel compression, then turn it another 1/4 turn. Both valves should be just closed and the piston at the top dead centre (TDC). 
# The correct clearances are between 0.04 mm and 0.10 mm between the rocker arm and the valve. A 0.04 mm feeler gauge (the thinner one) can be inserted, a thicker one (0.10 mm) cannot. 
# If the gap is narrower than 0.04 mm or wider than 0.10 mm, carefully loosen the lock nut on the rocker arm with a 5 mm wrench; turn the adjusting screw to increase the clearance about half a turn counter clockwise. Insert 0.04 mm feeler gauge between the rocker arm and the valve and gently screw the adjusting screw (clockwise) until it hits the feeler gauge. 
# Tighten the lock nut again. Remove the feeler gauge, crank the engine a few times and check the valve clearance again 
# Finally, screw the valve cover back on. 

<!--T:81-->
{{Note|type=warn|text='''Attention:''' Incorrect valve clearance can cause starting difficulties (valves do not open correctly) or loss of power (valves do not open sufficiently).}}

=== What to do in the Event of a Failure? === <!--T:82-->

==== A guide to the warranty and post-warranty repairs ==== <!--T:83-->

<!--T:84-->
==== Warranty Conditions ====
Since this engine, which requires regular maintenance and care, is intended for operation by the modeller under conditions of much higher performance and load on the model than those to which toys in the ordinary sense of the word are exposed, we cannot assume (and it cannot be supposed) any guarantee relating to how long it takes before individual parts need to be replaced due to wear. Engine parts wear out and require replacement over time. If any part of the engine appears to be damaged, defective or incorrectly installed when the engine is new – before the first start – this part will be repaired or replaced free of charge. Engines are only protected by the warranty against manufacturing defects in material, workmanship or assembly when new (before use). If any part is found to be defective, incorrectly manufactured or incorrectly assembled during the statutory warranty period, it will be repaired or replaced by the importer free of charge. If you believe that the defect in material, workmanship or assembly was not apparent when the model was new and only became apparent after the product was used, then please contact KAVAN Europe s.r.o. (e-mail: info@kavanrc.com, tel. +420 446 260 133). We firmly believe in the quality of the products we sell and will do our utmost to ensure that you are satisfied with them.
