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 some-

one 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.

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.

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 opera-

tion, pull the switch trigger and then push in the lock but-

ton. To stop the tool from the locked position, pull the

switch trigger fully, then release it.

Reversing switch action (Fig. 2)

This tool has a reversing switch to change the direction of

rotation. Move the reversing switch lever to the

D posi-

tion (A side) for clockwise rotation or the

E 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.

• When you operate the tool in counterclockwise rotation,

the switch trigger is pulled only halfway and the tool

runs at half speed. For counterclockwise rotation, you

cannot push in the lock button.

Selecting the action mode

Rotation with hammering (Fig. 3)

For drilling in concrete, masonry, etc., depress the lock

button and rotate the action mode changing knob to the

symbol. Use a tungsten-carbide tipped bit.

Rotation only (Fig. 4)

For drilling in wood, metal or plastic materials, depress

the lock button and rotate the action mode changing

knob to the symbol. Use a twist drill bit or wood bit.

Hammering only (Fig. 5)

For chipping, scaling or demolition operations, depress

the lock button and rotate the action mode changing

knob to the symbol. Use a bull point, cold chisel, scal-

ing 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 posi-

tions.

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.

• Hole saws cannot be used with this tool. They tend to

pinch or catch easily in the hole. This 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. 6)

CAUTION:

• Always use the side grip to ensure operating safety.

Install the side grip so that the teeth on the grip fit in

between the protrusions 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.
