General Power Tool Safety Warnings

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

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.

3. Hold power tool by insulated gripping sur-faces, when performing an operation where the cutting accessory may contact hidden wir-ing 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.

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 recom-mended 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 warm-up, 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 : DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety rules for the subject product. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.

CAUTION:

• Always set the knob fully to your desired mode symbol. If you operate the tool with the knob positioned halfway between the mode symbols, the tool may be damaged.
• Use the knob after the tool comes to a complete stop.

For Models HR2310T, HR2610, HR2610T, HR2611F, HR2611FT

Rotation with hammering

Fig.7: 1. Rotation with hammering 2. Action mode changing knob
For drilling in concrete, masonry, etc., rotate the action mode changing knob to the symbol. Use a tung-sten-carbide tipped bit.

Rotation only

Fig.8: 1. Rotation only

For drilling in wood, metal or plastic materials, rotate the action mode changing knob to the symbol. Use a twist drill bit or wood bit.

Hammering only

Fig.9: 1. Hammering only
For chipping, scaling or demolition operations, rotate the action mode changing knob to the symbol. Use a bull point, cold chisel, scaling chisel, etc.

CAUTION:

• Do not rotate the action mode changing knob 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 action mode changing knob is always positively located in one of the three action mode positions.
• Do not force the action mode change knob or do not move it from symbol mode to symbol mode (or vise versa) at once. It may damage the tool. When turning the knob from symbol mode to symbol mode (or vise versa), stop it at symbol mode once. And rotate the chuck clockwise (looking from the chuck side) half turn or until it clicks. Then turn the knob to
  the desired mode. If it is still difficult to turn the
  knob, rotate the chuck again.

Torque limiter

The torque limiter will actuate when a certain torque level is reached. The motor will disengage from the out-put 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.
• Bits such as hole saw, which tend to pinch or catch easily in the hole, are not appropriate for this tool. This is because they will cause the torque limiter to actuate too frequently.

ASSEMBLY

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

Side grip (auxiliary handle)

Fig.10: 1. Protrusions 2. Grooves

CAUTION:
Always use the side grip to ensure operating safety.

OPERATION

Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations.

Hammer drilling operation

Fig.28

Set the action mode changing knob to th symbol. Position the bit at the desired location for the hole, then pull the switch trigger. Do not force the tool. Light pres-sure 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.
Set the action mode changing knob to the symbol.

CAUTION:

There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking rein-forcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. Failure to do so may result in the loss of control of the tool and potentially severe injury.

NOTE: Eccentricity in the bit rotation may occur while operating the tool with no load. The tool automatically centers itself during operation. This does not affect the drilling precision.

Blow-out bulb (optional accessory)

Fig.29: 1. Blow-out bulb

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

wise to tighten the chuck. To remove the bit, hold the ring and turn the sleeve counterclockwise.
Set the action mode changing knob to the symbol. You can drill up to 13 mm diameter in metal and up to 32 mm diameter in wood.

CAUTION:

• Never use “rotation with hammering” when the quick change drill chuck is installed on the tool. The quick change drill chuck may be damaged. Also, the drill chuck will come off when reversing the tool.
• Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool.
• There is a tremendous twisting force exerted on the tool/bit at the time of hole breakthrough. Hold the tool firmly and exert care when the bit begins to break through the workpiece.
• A stuck bit can be removed simply by setting the reversing switch to reverse rotation in order to back out. However, the tool may back out abruptly if you do not hold it firmly
• Always secure small workpieces in a vise or similar hold-down device.

Diamond core drilling

When performing diamond core drilling operations, always set the change lever to the position to use “rotation only” action.

CAUTION:
If performing diamond core drilling operations using “rotation with hammering” action, the diamond core bit may be damaged.

Operation when using the dust cup (accessory)

Fig.35: 1. Dust cap

Operate the tool with the dust cup against the ceiling surface.

NOTE:

• The dust cup (accessory) is intended only for drilling in the ceramic workpiece such as concrete and mortar. Do not use the tool with the dust cup when drilling in metal or similar. Using the dust cup for drilling in the metal may damage the dust cup due to the heat produced by small metal dust or similar.
• Empty the dust cup before removing a drill bit.
• When using the dust cup, make sure that the dust cap is mounted on it securely.

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.
