• Due to the continuing program of research and
development, the specifications herein are subject
to change without prior notice.
• Note: Specifications may differ from country to

Power supply
The machine should be connected only to a power
supply of the same voltage as indicated on the
nameplate, and can only be operated on single-phase
AC supply. They are double-insulated in accordance
with European Standard and can, therefore, also be
used from sockets without earth wire.
Safety hints
For your own safety, please refer to enclosed safety
instructions.
ADDITIONAL SAFETY RULES
1. Wear a hard hat (safety helmet), safety glasses
and/or face shield. It is also highly recom-
mended that you wear a dust mask, ear pro-
tectors and thickly padded gloves.
2. Be sure the bit is secured in place before
operation.
3. Under normal operation, the machine is
designed to produce vibration. The screws
can come loose easily, causing a breakdown
or accident. Check tightness of screws care-
fully before operation.
4. In cold weather or when the machine has not
been used for a long time, let the machine
warm up for several minutes by operating it
under no load. This will loosen up the lubrica-
tion. Without proper warm-up, hammering
operation is difficult.
5. Always be sure you have a firm footing. Be
sure no one is below when using the machine
in high locations.
6. Hold the machine firmly with both hands.
7. Keep hands away from moving parts.

it in until it engages. (Fig. 2)
If the bit cannot be pushed in, remove the bit. Pull the
chuck cover down a couple of times. Then insert the
bit again. Turn the bit and push it in until it engages.

After installing, always make sure that the bit is
securely held in place by trying to pull it out.
To remove the bit, pull the chuck cover down all the
way and pull the bit out. (Fig. 4)
Adjusting depth of drilling (Fig. 4)
Loosen the wing bolt and adjust the depth gauge to
the desired depth. After adjusting, tighten the wing
bolt.
NOTE:
The depth gauge cannot be used at the position
where the depth gauge strikes against the gear
housing.
Side grip (Auxiliary handle) (Fig. 4)
The side grip swings around to either side, allowing
easy handling of the machine in any position. Loosen
the wing bolt on the side grip and swing the side grip
