General Power Tool SafetyWarnings

GEA010-1

WARNING Read all safety warnings and all

instructions. Failure to follow the warnings and

instructions may result in electric shock, fire and/or

serious injury.

Save all warnings and instructions for future reference.

ROTARY HAMMER SAFETY WARNINGS

GEB007-6

DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety rules for the subject product. 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 handle(s), if supplied with the tool.

Loss of control can cause personal injury.

1. Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
2. 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.
3. Be sure the bit is secured in place before operation.
4. 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.
5. 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.
6. Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations.
7. Hold the tool firmly with both hands.
8. Keep hands away from moving parts.
9. Do not leave the tool running. Operate the tool only when hand-held.
10. Do not point the tool at any one in the area when operating. The bit could fly out and injure someone seriously.

11. Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin.

12. 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.

• If the tool is operated continuously at low speeds for a long time, the motor will get overloaded, resulting in tool malfunction.
• The speed adjusting dial can be turned only as far as 5 and back to 1. Do not force it past 5 or 1, or the speed adjusting function may no longer work.

Selecting the action mode

Rotation with hammering (Fig. 4 & 5)

For drilling in concrete, masonry, etc., depress the lock button and rotate the change lever so that the pointer points to the _总 symbol. Use a tungsten-carbide tipped bit.

Hammering only

FOR MODEL HR4501C AND HR4510 (Fig. 6)

For chipping, scaling or demolition operations, depress the lock button and rotate the change lever so that the pointer points to the symbol. Use a bull point, cold chisel, scaling chisel, etc.

For long time hammering (FOR MODELS HR4501C AND HR4510C ONLY) (Fig. 7)

For chipping, scaling or demolition operations, depress the lock button and rotate the change lever so that the pointer points to the ⑦ symbol. Use a bull point, cold chisel, scaling chisel, etc.

CAUTION:

• When using the tool in the ③ symbol mode, the switch trigger does not work and only the slide switch works.

FOR MODEL HR4511C (Fig. 8)

For chipping, scaling or demolition operations, depress the lock button and rotate the change lever so that the pointer points to the symbol. Use a bull point, cold chisel, scaling chisel, etc.

CAUTION:

• Do not rotate the change lever when the tool is running under load. The tool will be damaged.
• To avoid rapid wear on the mode change mechanism, be sure that the change lever is always positively located in one of the two or three action mode positions.

Torque limiter

The torque limiter will actuate when a certain torque level is reached. The motor will disengage from the output shaft. When this happens, the bit will stop turning.

CAUTION:

• As soon as the torque limiter actuates, switch off the tool immediately. This will help prevent premature wear of the tool.

Indicator lamp (Fig. 9)

The green power-ON indicator lamp lights up when the tool is plugged. If the indicator lamp does not light up, the mains cord or the controller may be defective. The indicator lamp is lit but the tool does not start even if the tool is switched on, the carbon brushes may be worn out, or the controller, the motor or the ON/OFF switch may be defective.

The red service indicator lamp lights up when the carbon brushes are nearly worn out to indicate that the tool needs servicing. After approx. 8 hours of use, the motor will automatically be shut off.

ASSEMBLY

CAUTION:

Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.

Side handle (Fig. 10)

CAUTION:

• Use the side handle only when chipping, scaling or demolishing. Do not use it when drilling in concrete, masonry, etc. The tool cannot be held properly with this side handle when drilling.

The side handle can be swung 360^ on the vertical and secured at any desired position. It also secures at eight different positions back and forth on the horizontal. Just loosen the clamp nut to swing the side handle to a desired position. Then tighten the clamp nut securely. (Fig. 11)

Side grip (Fig. 12)

CAUTION:

Always use the side grip to ensure operating safety when drilling in concrete, masonry, etc.

The side grip swings around to either side, allowing easy handling of the tool in any position. Loosen the side grip by turning it counterclockwise, swing it to the desired position and then tighten it by turning clockwise.

Installing or removing the bit (Fig. 13)

Clean the bit shank and apply bit grease before installing the bit.

Insert the bit into the tool. Turn the bit and push it in until it engages. (Fig. 14)

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. 15)

Bit angle (when chipping, scaling or demolishing) (Fig. 16 & 17)

The bit can be secured at 12 different angles. To change the bit angle, depress the lock button and rotate the change lever so that the pointer points to the symbol. Turn the bit to the desired angle.

Depress the lock button and rotate the change lever so that the pointer points to the symbol. Then make sure that the bit is securely held in place by turning it slightly. (Fig. 18 & 19)

Depth gauge (Fig. 20)

The depth gauge is convenient for drilling holes of uniform depth. Loosen the clamp screw and adjust the depth gauge to the desired depth. After adjusting, tighten the clamp screw firmly.

NOTE:

• The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing/motor housing.

OPERATION

Hammer drilling operation (Fig. 21)

Set the change lever to the _^ symbol.

Position the bit at the desired location for the hole, then pull the switch trigger. Do not force the tool. Light pressure gives best results. Keep the tool in position and prevent it from slipping away from the hole.

Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, then remove the bit partially from the hole. By repeating this several times, the hole will be cleaned out and normal drilling may be resumed.

CAUTION:

• When the bit begins to break through concrete or if the bit strikes reinforcing rods embedded in concrete, the tool may react dangerously. Maintain good balance and safe footing while holding the tool firmly with both hands to prevent dangerous reaction.

Blow-out bulb (optional accessory) (Fig. 22)

After drilling the hole, use the blow-out bulb to clean the dust out of the hole.

Chipping/Scaling/Demolition (Fig. 23)

Set the change lever to the symbol.

Hold the tool firmly with both hands. Turn the tool on and apply slight pressure on the tool so that the tool will not bounce around, uncontrolled. Pressing very hard on the tool will not increase the efficiency.

MAINTENANCE

CAUTION:

Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
- Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result. This tool requires no hourly or daily lubrication because it has a grease-packed lubrication system. It should be lubricated every time the carbon brushes are replaced. Send the complete tool to Makita Authorized Service Center for this lubrication service.

To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts.
