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.

HAMMER DRILL SAFETY WARNINGS

1. Wear ear protectors when impact drilling.
   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. Always be sure you have a firm footing.
   Be sure no one is below when using the tool inhigh locations.

5. Hold the tool firmly with both hands.

6. Keep hands away from rotating parts.

7. Do not leave the tool running. Operate the tool only when hand-held.

8. Do not touch the bit or the workpieceimmediately after operation; they may beextremely hot and could burn your skin.

9. Some material contains chemicals which maybe 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.

FUNCTIONAL DESCRIPTION

CAUTION:

• Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.

Switch action
Fig.1
CAUTION:

• Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.
  

• Switch can be locked in “ON” position for ease of operator comfort during extended use. Apply caution when locking tool in “ON” position and maintain firm grasp on tool.
  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 HP1640F,HP1641F
Fig.2
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.

• Never use gasoline or thinner to clean the lens of the lamp, or it will be damaged.

Reversing switch action
Fig.3
This tool has a reversing switch to change the direction of rotation. Move the reversing switch to the position (A side) for clockwise rotation or the 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.
• If the switch trigger can not be depressed, check to see that the reversing switch is fully set to position  (A side) ****or (B side).

Fig.4
This tool has an action mode change lever. For rotationwith hammering, slide the action mode change lever tothe right ( T symbol). For rotation only, slide the actionmode change lever to the left ( symbol).

CAUTION:

• Always slide the action mode change lever all the way to your desired mode position. If you operate the tool with the lever positioned halfway between the mode symbols, the tool may be damaged.

ASSEMBLY

CAUTION:

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

Installing side grip (auxiliary handle)
Fig.5
Always use the side grip to ensure operating safety.
Install the side grip on tool barrel.
Then tighten the grip by turning clockwise securely at the desired position. It may be swung 360° so as to be secured at any position.

NOTE:

• The side grip cannot swing 360° when the depth gauge is installed.
  Installing or removing drill bit
  For Model HP1640, HP1640F Fig.6
  To install the bit, place it in the chuck as far as it will go.
  Tighten the chuck by hand. Place the chuck key in each of the three holes and tighten clockwise. Be sure to tighten all three chuck holes evenly.
  To remove the bit, turn the chuck key counterclockwise in just one hole, then loosen the chuck by hand.
  After using the chuck key, be sure to return to the original position.

For Model HP1641, HP1641F
Fig.7
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.
Depth gauge
Fig.8
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 tool body.

OPERATION

Hammer drilling operation
Fig.9
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. When drilling in concrete, granite, tile, etc., move the action mode changing lever to the position of T symbol to use “rotation with hammering” action. Be sure to use a tungsten-carbide tipped bit. 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.
Blow-out bulb (optional accessory)
Fig.10
After drilling the hole, use the blow-out bulb to clean the dust out of the hole.
Drilling operation
When drilling in wood, metal or plastic materials, move the action mode changing lever to the position of symbol to use “rotation only” action.
Drilling in wood
When drilling in wood, the best results are obtained with wood drills equipped with a guide screw. The guide screw makes drilling easier by pulling the bit into the workpiece.

Drilling in metal
To prevent the bit from slipping when starting a hole, make an indentation with a center-punch and hammer at the point to be drilled. Place the point of the bit in the
indentation and start drilling.
Use a cutting lubricant when drilling metals. The exceptions are iron and brass which should be drilled dry.

CAUTION:

• 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 force exerted on the tool/bit at the time of hole break through. 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.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
  To maintain product SAFETY and RELIABILITY, repairs, carbon brush inspection and replacement, any other maintenance or adjustment should be performed by
  Makita Authorized Service Centers, always using Makita replacement parts.
