Manual 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.
Use of a water suction ring is mandatory for „overhead drilling".
Diamond drill bits with a 1 ¼" UNC female thread and R ½" male thread can
be screwed directly onto the working spindle.
Use only appropriate drill bits for the material to be drilled in. You can
protect your tool by using only well balanced drill bits without deformation.
Make sure that the diamond segments have sufficient cutting clearance
towards the bit body.
The PLD 182.1 NT is equipped with a 3-gear oil-
bath gearing. Select the speed according to the
drilling diameter.
Use the gear selector to change to next higher or
lower gear.
If gear changing is too heavy, slightly turn the
working spindle to ease gear changing.
