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.

GEB007-7
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 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.
  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 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.

For drilling in concrete, masonry, etc., rotate the action mode changing knob to the symbol. Use a tungsten-carbide tipped bit.

Rotation only
Fig.8

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
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.
  • When changing from the  symbol mode to the  symbol mode, the action mode changing knob may no longer move in the  symbol position. At this time, turn the tool on or turn the chuck by hand in the symbol position and then rotate the action mode changing knob. Forcing the action mode changing knob may cause tool damage.

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.
  • 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
CAUTION:

  • Always use the side grip to ensure operating safety. Install the side grip so that the protrusions on the grip fit in between the grooves 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.

Bit grease
Coat the bit shank head beforehand with a small amount of bit grease (about 0.5 – 1 g). This chuck lubrication assures smooth action and longer service life.

Fig.18 Adjust the depth gauge to the desired depth by moving it back and forth while pressing the lock button. After the adjustment, release the lock button to lock the depth gauge.

Fig.19
NOTE:

  • Inserting the depth gauge with its toothed side not directed to the toothed side of hex hole marking on the grip base as shown in the figure does not allow the depth gauge to be locked.

Dust cup
Fig.20
Use the dust cup to prevent dust from falling over the tool and on yourself when performing overhead drilling operations. Attach the dust cup to the bit as shown in the figure. The size of bits which the dust cup can be attached to is as follows.

Bit diameter
Dust cup 5 6 mm – 14.5 mm
Dust cup 9 12 mm – 16 mm

There is another type of dust cup (accessory) which helps you prevent dust from falling over the tool and on yourself when performing overhead drilling operations.

Installing or removing the dust cup
Fig.21

Before installing the dust cup, remove the bit from the tool if installed on the tool. Install the dust cup (accessory) on the tool so that the symbol on the dust cup is aligned with the grooves in the tool.

NOTE:

  • When installing or removing the dust cup, the cap may come off the dust cup. At that time, proceed as follows. Remove the bellows from the attachment and fit the cap from the side shown in the figure with its carved side facing upward so that the groove in the cap fits in the inside periphery of the attachment. Finally, mount the bellows that has been removed.

Fig.27
NOTE:

  • If you connect a vacuum cleaner to your hammer, cleaner operations can be performed. Dust cap needs to be removed from the dust cup before the connection.

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 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.

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

Chipping/Scaling/Demolition
For Models HR2310T, HR2610, HR2610T, HR2611F, HR2611FT

Fig.30
Set the action mode changing knob 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.

Drilling in wood or metal
For Models HR2300, HR2600, HR2601, HR2610, HR2611F

Fig.31
Use the optional drill chuck assembly. When installing it, refer to “Installing or removing the bit” described on the previous page.

For Models HR2310T, HR2610T, HR2611FT
Fig.32
Fig.33
Use the quick change drill chuck as standard equipment. When installing it, refer to “changing the quick change chuck for SDS-plus ” described on the previous page.

Fig.34
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 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
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.
