and pull the bit out.

Depth gauge

007965

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

001300

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

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:

• 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. 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

precision.

Blow-out bulb (optional accessory)

002449

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

dust out of the hole.
