Operating the power tool

Charging

Note: The battery is supplied partially charged. To ensure the ma ximum performance of the battery, charge it before first use.

Charge the power tool only with the USB cable provided.
Connect the USB cable to a suitable USB power supply (5 V, min. 0.5 A).
Charging: the indicator LED glows red. Charging finished: the indicator LED glows green. During the charging process, the handle of the power tool might become warm. This is normal.
Once fully charged unplug the USB cable from the power tool and power supply.
The power tool cannot be used during the charging process; if the power tool does not respond during the charging process, it is not a failure.

Protection against deep discharge

The lithium-ion battery is protected against deep discharge by the electronic cell protection. When the battery is discharged, the power tool is switched off by means of a protective circuit; it no longer rotates. However, you should never let it go that far; you should recharge the battery once you realize your power tool is apparently slowing down.

Maintenance and service

To ensure safe and efficient operation, always keep the power tool clean.
If the power tool is no longer working and/or the battery needs to be replaced, this must be done by KAVAN or by a KAVAN authorised service centre.

Transport

The contained lithium-ion batteries are subject to the Dangerous Goods Legislation requirements. The batteries are suitable for road transport by the user without further restrictions. When shi pping by third parties (e.g. by air transport), special requirements on packaging and labelling must be observed.
