8 Drill Chuck (Accessory)
For drilling work in metal, wood and plastic with drills
that have normal shafts, a drill chuck (13 mm max.
chuck opening) is available. The drill chuck is
mounted on the adapter (accessory) for screwdriver
bits. All common drill chucks with 1/2" x 20 UNF inter-
nal threads (13 mm max. chuck opening) can be
used.
MOUNTING THE CHUCK
Before any work on the machine itself, pull the
mains plug!
Clean the threads of the drill chuck (accessory) and
the adapter 13 (accessory). Screw the drill chuck onto
the adapter and tighten firmly (approx. 30 Nm). Clamp
in a vise for tightening the adapter, for example.
Clamp an Allen key in the drill chuck and use it to
tighten the chuck. Then lock the adapter in the tool
holder the same as a drill.
9 Practical Tips
Do not drill into hidden electrical
lines or gas and water pipes.
Check the area to be worked with
a metal detector, for example,
before starting.
For metal, use only flawless, sharpened drills; for
stone and concrete, only masonry drills with hard
metal inserts.
Always adapt the speed to the material to be worked
and the diameter of the drill. For precision working
with metal and wood, place the machine in a drill
stand (accessory).
HAMMER- DRILLING
Wear protective glasses and
hearing protection.
Do not apply to much pressure. The performance is
not increased in this manner.
For hammer drilling, work only with protective
glasses, hearing protection and the auxiliary han-
dle 12. Check before putting into operation if the
shift knob 10 is latched in the
DRILLING IN TILES
Start drilling slowly on the tile. After the tile is drilled
through, switch to impact drilling.
SCREWDRIVING
Screwdriver bits can be inserted into the adapter 13
(accessory). Commercially available bits with a hex-
agonal dimension of 6.3 mm or 1/4" (DIN 3126,
Form C) can be used.
The screwdriver bits are held in the adapter with a
spring ring. Therefore, use only bits with a notch.
10 Slip Clutch
If the drilling tool become jammed or get caught, the
slip clutch releases.
Remove the load from the machine immediately by
pulling back the drilling tool.
Always hold the machine tightly with both hands and
assume a secure stance.
11 Maintenance Measures
Before any work on the machine itself, pull the
mains plug!
Always keep the ventilation slots clean.
Wipe off the accessible plastic parts regularly with a
cloth without cleaning agent.
After heavy use over a long period, the machine
should be taken to a Kress service location for an
inspection and thorough cleaning.
