the eyes and body.
CAUTION
The work generates noise. Wear ear protectors.
Exposure to noise can cause hearing loss.
7.2.1 Working at low temperatures
NOTE
The hammering mechanism works only when the

Bring the drill bit briefly into contact with the base

no load until the minimum operating temperature is
reached. If necessary, repeat this procedure until the
hammering mechanism begins to operate.
