until it stops.

2. How to bore (Fig. 18)
(1) Connect the plug to the receptacle.
(2) A spring is installed in the center pin.
Push it lightly to the wall or the floor

depth the position of the hole will
establish. Bore after that removing the
center pin and the guide plate from core
bit.

only expedite the work, but will
deteriorate the tip edge of the drill bit,
resulting in reduced service life of the
rotary hammer.

guide plate, turn OFF the switch and
disconnect
receptacle.
