REMOVING TOOLS
Slide the unlocking collar 3 to the rear and pull out the
tool.
ADJUSTING THE CHISEL
Set the rotation stop switch 4 to an intermediate posi-
tion. The chisel can now be turned by hand to the
required working position.
Return the rotation stop switch 4 to the initial
position . The chisel latches automatically as soon
as it is radially loaded by the working or chiselling
process.
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 lock the
adapter in the same manner as a drill in the tool
holder. To tighten the drill chuck, set the rotation stop
switch 4 temporarily to position
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).

IMPACT DRILLING - CHISELING
Wear protective glasses and
hearing protection.
Do not apply to much pressure.
The performance is not increased
in this manner.
The most effective method for chiselling is to break
out only small pieces of material.
When chiselling, work only with protective glasses
and the auxiliary handle 12. Check before starting
to work if the rotation stop switch 4 is engaged in
the position.
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 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 FLEX service location for an
inspection and thorough cleaning.
