Intended use
The tool is intended for hammer drilling and drilling in
brick, concrete and stone as well as for chiseling work.
It is also suitable for drilling without impact in wood,
metal, ceramic and plastic.
Power supply
The tool 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 the enclosed safety
instructions.

ADDITIONAL SAFETY RULES

1. Hold tools by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord. Con-
tact with a "live" wire will make exposed metal
parts of the tool "live" and shock the operator.
2. Wear ear protectors when using the tool for
extended periods. Prolonged exposure to high
intensity noise can cause hearing loss.
3. Wear a hard hat (safety helmet), safety glasses
and/or face shield. It is also highly recom-
mended that you wear a dust mask, and thickly
padded gloves.
4. Be sure the bit is secured in place before opera-
tion.

5. Under normal operation, the tool is designed to
produce vibration. The screws can come loose
easily, causing a breakdown or accident. Check
tightness of screws carefully before operation.
6. In cold weather or when the tool has not been
used for a long time, let the tool warm up for a
while by operating it under no load. This will
loosen up the lubrication. Without proper warm-
up, hammering operation is difficult.
7. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
8. Hold the tool firmly with both hands.
9. Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool
only when hand-held.
11. Do not point the tool at any one in the area when
operating. The bit could fly out and injure some-
one seriously.
12. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Side grip (auxiliary handle) (Fig. 1)
Always use the side grip to ensure operating safety.
Install the side grip so that the teeth on the grip fit in
between the protrusions on the tool barrel. Then tighten
the grip by turning clockwise at the desired position. It
may be swung 360° so as to be secured at any position.
Installing or removing the bit
CAUTION:
Always be sure that the tool is switched off and
unplugged before installing or removing the bit.
Clean the bit shank and apply bit grease before installing
the bit. (Fig. 2)
Insert the bit into the tool. Turn the bit and push it in until
it engages. (Fig. 3)
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)
