APPLICATIONS

By combined actions of ROTATION and IMPACT: Boring holes in hard materials (concrete, marble, granite, tiles, etc.)
By ROTATIONAL action:

Boring holes in metal, wood and plastic.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate.

2. Power switch

Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, inviting serious accident.

3. Extension cord

When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

4. Selecting the appropriate drill bit

When boring concrete or stone
Use the drill bits specified in the Optional Accessories.
When boring metal or plastic
Use an ordinary metalworking drill bit.

When boring wood

Use an ordinary woodworking drill bit.

However, when drilling 6.5mm or smaller holes, use a metalworking drill bit.

5. Mounting and dismounting of the bit.

For keyed chuck (Fig. 1)

(1) Open the chuck jaws, and insert the bit into the chuck.
(2) Place the chuck wrench in each of the three holes in the chuck, and turn it in the clockwise direction (viewed from the front side). Tighten securely.
(3) To remove the bit, place the chuck wrench into one of the holes in the chuck and turn it in the counterclockwise direction.

Forkeyless chuck

The country of use will determine whether Type A or Type B keyless chuck is required.

Type A (Fig. 2)
(1) Mounting the bit

Turn the lock collar in the direction "AUF" and open the chuck. After inserting the drill bit into the chuck as far it will go, turn the lock collar in the "ZU" direction. Grip the ring and close the chuck by turning the sleeve clockwise as viewed from the front.

(2) Dismounting the bit

Turn the lock collar in the direction "AUF" to release the chucking force. Grip the ring and open the chuck by turning the sleeve counterclockwise.

NOTE

When the sleeve does not become loose any further, fix the side handle to ring, hold side handle firmly, then turn the sleeve to loosen by hand. (Fig. 4)

Type B (Fig. 3)
(1) Mounting the bit

Turn the sleeve counterclockwise and open the chuck. After inserting the drill bit into the chuck as far it will go, grip the ring and close the chuck by turning the sleeve clockwise as viewed from the front.

(2) Dismounting the bit

Grip the ring and open the chuck by turning the sleeve counterclockwise.

NOTE

When the sleeve does not become loose any further, fix the side handle to ring, hold side handle firmly, then turn the sleeve to loosen by hand. (Fig. 4)

6. Check the rotational direction (Fig. 5)

The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the push button.

The L-side of the push button is pushed to turn the bit counterclockwise.

(The L) and (R) marks are provided on the body.) CAUTION

Always use the impact drill with clockwise rotation, when using it as an impact drill.

7. Fixing the side handle (Fig. 6)

Attach the side handle to the mounting part.

Rotate the side handle grip in a clockwise direction to secure it.

Set the side handle to a position that is suited to the operation and then securely tighten the side handle grip.

To attach a depth gauge on the side handle, insert the gauge into the U-shaped groove on the side handle, adjust the position of the depth gauge in accordance with the desired depth of the hole, and firmly tighten the side handle grip. (Fig. 7)

8. IMPACT to ROTATION changeover (Fig. 8)

Shift the change lever between the right and left positions to switch easily between IMPACT (rotation and impact) and ROTATION (rotation only), respectively.

To bore holes in hard materials such as concrete, stone and tiles, shift the change lever to the right-hand position (as indicated by the T mark).

The drill bit operates by the combined actions of impact and rotation.

To bore holes in metal, wood and plastic, shift the change lever to the left-hand position (as indicated by the 1 mark). The drill bit operates by rotational action only, as in the case of a conventional electric drill.

CAUTION

Do not use the Impact Drill in the IMPACT function if the material can be bored by rotation only. Such action will not only reduce drill efficiency, but may also damage the drill tip.
Operating the Impact Drill with the change lever in mid-position may result in damage. When switching, make sure that you shift the change lever to the correct position.

9. High-speed/Low-speed changeover:

Prior to changing speed, ensure that the switch is in the OFF position, and the drill has come to a complete stop.

To change speed, rotate the gear shift dial as indicated by the arrow in Fig. 9. The numeral "1" engraved on the drill body denotes low speed, the numeral "2" denotes high speed.

If it is hard to turn the gear shift dial, turn the chuck slightly in either direction and then turn the gear shift dial again.

HOW TO USE

1. Switch operation

• When the trigger is depressed, the tool rotates. When the trigger is released, the tool stops.
  The rotational speed of the drill can be controlled by varying the amount that the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the trigger switch is pulled more.
  The desired rotation speed can be pre-selected with the speed control dial. Turn the speed control dial clockwise for higher speed and counterclockwise for lower speed. (Fig. 10)
  Pulling the trigger and pushing the stopper, it keeps the switched-on condition which is convenient for continuous running. When switching off, the stopper can be disconnected by pulling the trigger again.

CAUTION

If the L-side of push button is pressed for reverse bit rotation, the stopper cannot be used.

2. Drilling

• When drilling, start the drill slowly, and gradually increasing speed as you drill.
  Always apply pressure in a straight line with the bit. Use enough pressure to keep drilling, but do not push hard enough to stall the motor or deflect the bit.
  To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit through the last part of the hole.
  If the drill stalls, release the trigger immediately, remove the bit from the work and start again. Do not click the trigger on and off in an attempt to start a stalled drill. This can damage the drill.
  The larger the drill bit diameter, the larger the reactive force on your arm.

Be careful not to lose control of the drill because of this reactive force.

To maintain firm control, establish a good foothold, use side handle, hold the drill tightly with both hands, and ensure that the drill is vertical to the material being drilled.

MAINTENANCE AND INSPECTION

1. Inspecting the drill bits

Since use of an abraded drill bits will cause motor malfunctioning and degraded efficiency, replace the drill bits with a new one or resharpening without delay when abrasion is noted.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

3. Maintenance of the motor

The motor unit winding is the very "heart" of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

1. Inspecting the carbon brushes

For your continued safety and electrical shock protection, carbon brush inspection and replacement on this tool should ONLY be performed by a Hitachi Authorized Service Center.
