9 Inserting/Removing Tools
The tool holder 1 clamps the drilling tools without
using a tool key.
INSERTING TOOLS
Before all work on the machine itself,
always set the rotational direction switch 7
to the middle position.
Clean and lightly grease the tool shaft.
Pull back the unlocking collar 3. Insert the tool while
turning into the tool holder until it latches. Release the
unlocking collar. Check whether the tool is firmly
seated.
Take care that the dust protection cap 2 is not dam-
aged.
Replace damaged dust protection caps!
REMOVING TOOLS
Slide the unlocking collar 3 to the rear and pull out the
tool.
10 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" × 20 UNF
internal threads (13 mm max. chuck opening) can be
used.
MOUNTING THE CHUCK
Before all work on the machine itself,
always set the rotational direction switch 7
to the middle position.
Clean the threads of the drill chuck (accessory) and
the adapter 18 (see accessory). Screw the drill chuck
onto the adapter and tighten firmly (approx. 30 Nm).
Clamp in a vise for tightening the adapter, for exam-
ple. 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.
11 Practical Tips
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
3
For hammer drilling, work only with protective
glasses, hearing protection and the auxiliary
handle 10. Check before putting into operation if
the shift knob 4 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 18
(see accessory). Commercially available bits with a
hexagonal 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.
