7.2.1 Working at low temperatures
NOTE
The hammering mechanism works only when the
power tool has reached a minimum operating tem-

Bring the drill bit into contact with the base material
and allow the power tool to run under no load until
the minimum operating temperature is reached. If
necessary, repeat this procedure until the hammering
mechanism begins to operate.
