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.

Depth gauge

Fig.20

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.

OPERATION

Hammer drilling operation

Fig.21

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.

Blow-out bulb (optional accessory)

Fig.22

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

dust out of the hole.

Chipping/Scaling/Demolition

Fig.23

Set the change lever to the

symbol.

Hold the tool firmly with both hands. Turn the tool on and

apply slight pressure on the tool so that the tool will not

bounce around, uncontrolled. Pressing very hard on the

tool will not increase the efficiency.

unplugged before attempting to perform inspection
