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.
ADJUSTING THE CHISEL
Set the gear selector/rotation stop switch 4 to an inter-
mediate position. The chisel can now be turned by
hand to the required working position.
Return the gear selector/rotation stop switch 4 to the
initial position
. The chisel latches automatically as
soon as it is radially loaded by the working or chisel-
ling process.
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 14 (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 gear selector/
rotation stop switch 4 temporarily to position
.
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 gear selector/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 14
(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.
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.
Kress takes back worn-out machines
for the purpose of resource-saving
recycling. As a result of their modular
construction, Kress machines can be
very easily dismantled into their reus-
able materials.
Give your worn-out Kress machine to your dealer or
send it directly to Kress.
