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 not operating the tool, always set the reversing

switch lever to the neutral position.

Selecting the action mode

Rotation with hammering (Fig. 5)

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. 6)

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.

CAUTION:

• Do not rotate the action mode changing knob when the

tool is running. 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 the bat-

tery cartridge is removed before carrying out any work

on the tool.

Side grip (auxiliary handle) (Fig. 7)

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.

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.

Installing or removing the bit

Clean the bit shank and apply bit grease before installing

the bit. (Fig. 8)

Insert the bit into the tool. Turn the bit and push it in until it

engages. (Fig. 9)

If the bit cannot be pushed in, remove the bit. Pull the

chuck cover down a couple of times. Then insert the bit

again. Turn the bit and push it in until it engages.

After installing, always make sure that the bit is securely

held in place by trying to pull it out.

To remove the bit, pull the chuck cover down all the way

and pull the bit out. (Fig. 10)

Depth gauge (Fig. 11)

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 gear housing.

Dust cup (Fig. 12)

Use the dust cup to prevent dust from falling over the tool

and on yourself when performing overhead drilling opera-

tions. 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.

OPERATION

Hammer drilling operation (Fig. 13)

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 repeat-

ing this several times, the hole will be cleaned out and

normal drilling may be resumed.

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 embed-

ded 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 preci-

sion.

Blow-out bulb (optional accessory)

(Fig. 14)

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

dust out of the hole.
