Indicator lamp (Fig. 8)

The green power-ON indicator lamp lights up when the
tool is plugged in. If the indicator lamp does not light up,
the mains cord or the controller may be defective.
When the indicator lamp lights up but the tool does not
start even the tool is switched on, the carbon brushes
may be worn out, or the controller, the motor or the ON/
OFF switch may be defective.
If above symptoms occur, stop using the tool immediately
and ask your local service center.
The red service indicator lamp lights up when the carbon
brushes are nearly worn out to indicate that the tool
needs servicing. After some period of use, the motor
automatically shuts off.

ASSEMBLY

CAUTION:

• Always be sure that the tool is switched off and

unplugged before carrying out any work on the tool.

Side handle

CAUTION:

• Use the side handle only when chipping, scaling or

demolishing. Do not use it when drilling in concrete,
masonry, etc. The tool cannot be held properly with this
side handle when drilling. 

(Fig. 9)

The side handle can be swung 360° on the vertical and
secured at any desired position. It also secures at eight
different positions back and forth on the horizontal. Just
loosen the clamp nut to swing the side handle to a
desired position. Then tighten the clamp nut securely.

(Fig. 10)

Side grip (Fig. 11) 

CAUTION:

• Always use the side grip to ensure operating safety

when drilling in concrete, masonry, etc. 

The side grip swings around to either side, allowing easy
handling of the tool in any position. Loosen the side grip
by turning it counterclockwise, swing it to the desired
position and then tighten it by turning clockwise. 

Installing or removing the bit

Clean the bit shank and apply bit grease before installing
the bit. 

(Fig. 12)

Insert the bit into the tool. Turn the bit and push it in until
it engages. 
If the bit cannot be pushed in, remove the bit. Pull the
release 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. 

(Fig. 13)

To remove the bit, pull the release cover down all the way
and pull the bit out. 

(Fig. 14)

Bit angle (when chipping, scaling or demolishing) 

The bit can be secured at 24 different angles. To change
the bit angle, rotate the change lever so that the pointer
points to the 

 symbol. Turn the bit to the desired angle.

(Fig. 15)

Rotate the change lever so that the pointer points to the

 symbol. Then make sure that the bit is securely held in

place by turning it slightly. 

(Fig. 16)

Depth gauge

The depth gauge is convenient for drilling holes of
uniform depth.

Press and hold the lock button, and insert the depth
gauge into the hex hole. 

(Fig. 17)

Make sure the toothed side of the depth gauge faces the
marking. 

(Fig. 18)

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

NOTE:

• The depth gauge cannot be used at the position where

the depth gauge strikes against the gear housing/motor
housing. 

OPERATION

CAUTION:

• Make sure the work material is secured and not

unstable. Flown object may cause personal injury.

• Do not pull the tool out forcibly even the bit gets stuck.

Loss of control may cause injury.

Hammer drilling operation (Fig. 19) 

Set the change lever 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 you can continue drilling operation.

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, and maintain
good balance and safe footing. Failure to do so may
result in the loss of control of the tool and potentially
severe injury.

Blow-out bulb (optional accessory) (Fig. 20) 

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

Chipping/Scaling/Demolition (Fig. 21) 

Set the change lever to the   or   symbol. 
Hold the tool firmly with both hands. Turn the tool on and
apply slight pressure on the tool so that the tool does not
bounce around, uncontrolled. Pressing very hard on the
tool will not increase the efficiency.

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.
