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.

Indicator lamp

Fig.9

The green power-ON indicator lamp lights up when the

tool is plugged. If the indicator lamp does not light up,

the mains cord or the controller may be defective. The

indicator lamp is lit but the tool does not start even if 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.

The red service indicator lamp lights up when the carbon

brushes are nearly worn out to indicate that the tool

needs servicing. After approx. 8 hours of use, the motor

will automatically be shut off.

ASSEMBLY

CAUTION:

• Always be sure that the tool is switched off and

unplugged before carrying out any work on the

tool.

Side grip

Fig.10

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

Fig.11

Clean the bit shank and apply bit grease before installing

the bit.

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

it engages.

Fig.12

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.

Bit angle (when chipping, scaling or

demolishing)

Fig.14

The bit can be secured at 24 different angles. To change

the bit angle, depress the lock button and rotate the

change lever so that the pointer points to the

symbol.

Turn the bit to the desired angle.

Depress the lock button and 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.

Depth gauge

Fig.15

The depth gauge is convenient for drilling holes of

uniform depth. Loosen the clamp screw and adjust the

depth gauge to the desired depth. After adjusting,

tighten the clamp screw firmly.

NOTE:

• The depth gauge cannot be used at the position

where the depth gauge strikes against the gear

housing/motor housing.

Dust cup

Fig.16

Use the dust cup to prevent dust from falling over the

tool and on yourself when performing overhead drilling

operations. 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.

Bit diameter

Dust cup 5 6 mm - 14.5 mm

Dust cup 9

12 mm - 16 mm

OPERATION

Hammer drilling operation

Fig.17

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 normal drilling may be resumed.

CAUTION:

• When the bit begins to break through concrete or if

the bit strikes reinforcing rods embedded in

concrete, the tool may react dangerously. Maintain

good balance and safe footing while holding the

tool firmly with both hands to prevent dangerous

reaction.
