•Due to our continuing program of research and development, 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
GEB007-2
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.
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. Turn the 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 (Fig. 8)
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.
Reversing switch action (Fig. 9)
This tool has a reversing switch to change the direction of rotation. Move the reversing switch lever to the Dposition (A side) for clockwise rotation or the E position (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 symbol. Pull forcefully in the direction of the arrow.
Attaching the quick change drill chuck
Check the line of the quick change drill chuck shows the
symbol. Grasp the change cover of the quick change drill chuck and set the line to the symbol. Place the quick change drill chuck on the spindle of the tool.
Grasp the change cover of the quick change drill chuck and turn the change cover line to the symbol until a click can clearly be heard.
Selecting action mode
Rotation with hammering (Fig. 12)
For drilling in concrete, masonry, etc., depress the lock button and rotate the action mode changing knob to the H symbol. Use a tungsten-carbide tipped bit.
Hammering only (Fig. 13)
For chipping, scaling or demolition operations, depress the lock button and rotate the action mode changing knob to the g symbol. Use a bull point, cold chisel, scaling chisel, etc.
Rotation only (Fig. 14)
For drilling in wood, metal or plastic materials, depress the lock button and rotate the action mode changing knob to the m symbol. Use a twist drill bit or wood bit.
