Attention!
Use the arrestor button only during operation with drill rig.
!
Its use during manual operation is not allowed.
If the machine stops for any reason or due to power failure,
immediately release the arrestor button by pressing the
ON/OFF switch.
If this button is not released, the tool may unintendedly
restart if the PRCD protective switch is operated and cause a
danger to the user.
Changing Gears
Choose the proper speed according to the drill bit size used.
Select at the speed selector by pressing-in, shifting and engaging.
If the selector is on "o" position, the speed can vary from 0 to 800 rpm.
If the selector is on "oo" position, the speed can vary from 0 to 1570 rpm.
CAUTION:
- always check the drill bit manufactures recommendation
for use
- gear shifting only when the machine is stopped and
clockwise
Manual Drilling
For wet drilling, we recommend the use of a dimpling aid with water removal (order No. 35847).
This type is a must for overhead drilling.
Open the ball valve and switch the tool on.
Hold the tool tight with both hands. Locate the tool slightly inclined. Once the drill bit is in the material (approx. 1/8
to 1/4 of the circumference), bring the tool into an angle of 90 degrees and continue drilling.
Take care that the drill bit is not out of line.
Advance the tool according to bit diameter and machine power. Observe the LED in the handle.
If it lights red, reduce your pressing force.
In case the bit gets jammed, to not dry to release it by switching the tool on and off. This would cause premature
wearing of the safety clutch. Switch the tool off immediately and unfix the drill bit by turning to the left or right using
an appropriate open-end wrench. Cautiously pull the tool out of the borehole.
Insert the gas spring with the water collecting ring
and the guide ring appropriate for the drill bit
diameter into the tension disk. Shift the gas spring up
to complete coverage of the bit segments by the
water collecting ring. Tighten the wing screw.
On drilling overhead, make sure that the water
supply is opened only after having switch the water
remover on and the removing unit was fixed to the
wall or ceiling.
