NOTE: If you connect a vacuum cleaner to the dust

cup set, remove the dust cap before connecting it.

► Fig.27: 1. Dust cap

To remove the dust cup set, remove the bit while pulling

the chuck cover in the direction of the arrow.

► Fig.28: 1. Bit 2. Chuck cover

Hold the root of dust cup and pull it out.

NOTE: If the cap comes off from the dust cup, attach

it with its printed side facing up so that groove on the

cap ts in the inside periphery of the attachment.

OPERATION

CAUTION: Always use the side grip (auxiliary

handle) and rmly hold the tool by both side grip

and switch handle during operations.

CAUTION: Always make sure that the work-

piece is secured before operation.

CAUTION: Do not pull the tool out forcibly

even the bit gets stuck. Loss of control may

cause injury.

CAUTION: The dust collection system is

intended for drilling in concrete only. Do not use

the dust collection system for drilling in metal or

wood.

CAUTION: When using the tool with the dust

collection system, be sure to attach the lter

to the dust collection system to prevent dust

inhalation.

CAUTION: Before using the dust collection

system, check that the lter is not damaged.

Failure to do so may cause dust inhalation.

CAUTION: The dust collection system col-

lects the generated dust at a considerable rate,

but not all dust can be collected.

NOTICE: Do not use the dust collection system

for core drilling or chiseling.

NOTICE: Do not use the dust collection system

for drilling in wet concrete or use this system

in wet environment. Failure to do so may cause

malfunction.

NOTE: If the battery cartridge is in low temperature,

the tool’s capability may not be fully obtained. In this

case, warm up the battery cartridge by using the

tool with no load for a while to fully obtain the tool’s

capability.

Hammer drilling operation

CAUTION: There is tremendous and sudden

twisting force exerted on the tool/drill 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 rmly hold the tool by

both side grip and switch handle during opera-

tions. Failure to do so may result in the loss of control

of the tool and potentially severe injury.

Set the action mode changing knob to the symbol.

Position the drill 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 drill bit partially from the hole.

By repeating this several times, the hole will be cleaned

out and normal drilling may be resumed.

NOTE: Eccentricity in the drill bit rotation may occur

while operating the tool with no load. The tool auto-

matically centers itself during operation. This does not

affect the drilling precision.

Chipping/Scaling/Demolition

Set the action mode changing knob to the symbol.

Hold the tool rmly 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

efciency.

► Fig.32

Drilling in wood or metal

CAUTION: Hold the tool rmly and exert care

when the drill bit begins to break through the

workpiece. There is a tremendous force exerted on

the tool/drill bit at the time of hole break through.

CAUTION: A stuck drill bit can be removed

simply by setting the reversing switch to reverse

rotation in order to back out. However, the tool

may back out abruptly if you do not hold it rmly.

CAUTION: Always secure workpieces in a

vise or similar hold-down device.

NOTICE: Never use “rotation with hammering”

when the drill chuck is installed on the tool. The

drill chuck may be damaged.

Also, the drill chuck will come off when reversing the

tool.

NOTICE: Pressing excessively on the tool will

not speed up the drilling. In fact, this excessive

pressure will only serve to damage the tip of your drill

bit, decrease the tool performance and shorten the

service life of the tool.

Set the action mode changing knob to the symbol.
