Intended use
The tool is intended for impact drilling in brick, concrete
and stone as well as 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
ENB002-1
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. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
3. Hold the tool firmly with both hands. Always use
the side grip.
4. Keep hands away from moving parts.
5. Do not leave the tool running. Operate the tool
only when hand-held.
6. Do not touch the bit or the workpiece immedi-
ately after operation; they may be extremely hot
and could burn your skin.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Installing side grip (auxiliary handle) (Fig. 1)
CAUTION:
Always be sure that the tool is switched off and
unplugged before installing or removing the side grip.
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 drill bit (Fig. 2 & 3)

Always be sure that the tool is switched off and
unplugged before installing or removing the bit.
For HP2050, HP2050F
To install the bit, place it in the chuck as far as it will go.
Tighten the chuck by hand. Place the chuck key in each

turn the chuck key counterclockwise in just one hole,
then loosen the chuck by hand. After using the chuck key,
be sure to return it to the original position.
For HP2051, HP2051F
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the bit in the chuck as far as it
will go. Hold the ring firmly and turn the sleeve clockwise
to tighten the chuck. To remove the bit, hold the ring and
