• Due to our continuing program of research and devel-
opment, the specifications herein are subject to change
without notice.
• Note: Specifications may differ from country to country.
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.
SPECIFIC SAFETY RULES
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to rotary hammer safety rules. If you use this tool
unsafely or incorrectly, you can suffer serious personal injury.
1. Wear ear protectors. Exposure to noise can cause
hearing loss.
2. Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
3. Hold power tools by insulated gripping surfaces
when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Contact with a “live” wire will make exposed metal
parts of the tool “live” and shock the operator.
GEB007-2
4. Wear a hard hat (safety helmet), safety glasses
and/or face shield. Ordinary eye or sun glasses
are NOT safety glasses. It is also highly recommended that you wear a dust mask and thickly
padded gloves.
5. Be sure the bit is secured in place before operation.
6. 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.
7. 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 warmup, hammering operation is difficult.
8. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
9. Hold the tool firmly with both hands.
10. Keep hands away from moving parts.
11. Do not leave the tool running. Operate the tool
only when hand-held.
12. Do not point the tool at any one in the area when
operating. The bit could fly out and injure someone seriously.
13. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
14. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
SAVE THESE INSTRUCTIONS.

WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.
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)
Bit angle (when chipping, scaling or demolishing)
CAUTION:
Always be sure that the tool is switched off and
unplugged before changing the bit angle.
The bit can be secured at the desired angle. To change
the bit angle, depress the lock button and rotate the
action mode changing knob to the O symbol. Tu r n th e
bit to the desired angle. (Fig. 5)
Depress the lock button and rotate the action mode
changing knob to the g symbol. Then make sure that
the bit is securely held in place by turning it slightly.
(Fig. 6)
Depth gauge (Fig. 7)
The depth gauge is convenient for drilling holes of uniform depth. Loosen the side grip and insert the depth
gauge into the hole in the side grip. Adjust the depth
gauge to the desired depth and tighten the side grip.
NOTE:
The depth gauge cannot be used at the position where
the depth gauge strikes against the gear housing.
Switch action (Fig. 8)
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the “OFF”
position when released.
To start the tool, simply pull the switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop. For continuous operation, pull the switch trigger and then push in the lock button. To stop the tool from the locked position, pull the
switch trigger fully, then release it.
Lighting up the lamps
For model HR2450F, HR2450FT
CAUTION:
Do not look in the light or see the source of light directly.
To turn on the lamp, pull the trigger. Release the trigger
to turn it off.
NOTE:
Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower the
illumination.
(Fig. 8)
Reversing switch action (Fig. 9)
This tool has a reversing switch to change the direction of
rotation. Move the reversing switch lever to the
tion (
A side) for clockwise rotation or the
(
B side) for counterclockwise rotation.
CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
• When you operate the tool in counterclockwise rotation,
the switch trigger is pulled only halfway and the tool
runs at half speed. For counterclockwise rotation, you
cannot push in the lock button.

Changing the quick change chuck for SDS-plus
(Fig. 10 & 11)
For model HR2450T/HR2450FT
The quick change chuck for SDS-plus can be easily
exchanged for the quick change drill chuck.
Removing the quick change chuck for SDS-plus
CAUTION:
• Before removing the quick change chuck for SDS-plus,
always remove the bit.
Grasp the change cover of the quick change chuck for
SDS-plus and turn in the direction of the arrow until the
change cover line moves from the symbol to the
