Initial operating of the power tool
• Always use the correct supply voltage: the power
supply voltage must match the information quoted on
the power tool identification plate.
• The power tool is supplied properly lubricated and
ready for use�
• A new power tool needs some time for its parts to
run in before a full load operation� The run-in period
duration is about 5 hours of operation�
• The gear lubrications require a short time to get
warm� Depending on the ambient temperature this
period of time can alter within the range of approxi-
mately 15 s (at ambient temperature of 32°С) up to 2
minutes (at ambient temperature of 0°С).
Switching the power tool on / off
Switching on:
Press on / off switch 12�
