ASSEMBLY
Before drilling
!
WARNING! Before drilling, check that all
locking screws are tightened well. Serious
accidents can occur if the concrete core
remains in the drill when backing out the
drill motor/drill from the floor, wall or ceiling.
!
WARNING! If the vacuum plate is used, make
sure the support surface is not porous and
can loosen from the floor or the wall. Make
sure that the vacuum pump has sufficient
power to secure the vacuum plate.
The vacuum plate must never be used for
ceiling drilling. Careless or incorrect use can
result in serious, even fatal injury.
IMPORTANT! Ensure that water cannot leak into the
machine when drilling in the ceiling. Use an appropriate
water collector and cover the machine in plastic, but do not
cover the air intakes and air outlets.
