These data are for the referential values. The number of

holes that can be drilled varies according to the sharpness

of the used bit or the conditions of the concrete being

drilled.

CAUTION

When using this unit continuously, the unit may

overheat, leading to damage in the motor and switch.

Please leave it without using it for approximately

15 minutes.

HOW TO USE

1. Switch operation

⅜ When the switch trigger is depressed, the tool

rotates. When the switch trigger is released, the tool

stops.

⅜ The rotational speed of the rotary hammer can be

controlled by varying the amount that the switch

trigger is pulled. Speed is low when the switch

trigger is pulled slightly and increases as the switch

trigger is pulled more.

⅜ When releasing the switch trigger, the brake will

be applied for immediate stopping.

2. Rotation + Hammering

Turn the change lever fully in the direction of the

“

” mark to set “rotation + hammering”.

(1) Mount the drill bit.

(2) Pull the trigger switch after applying the drill bit

tip to the drilling position. (Fig. 10)

(3) Pushing the rotary hammer forcibly is not necessary

at all. Pushing slightly so that drill dust comes out

gradually is just sufficient.

CAUTION

When the drill bit touches construction iron bar, the

bit will stop immediately and the rotary hammer

will react to revolve. Therefore please grip the side

handle and handle tightly as shown in Fig. 11.

3. Rotation only

Turn the change lever fully in the direction of the

“

” mark to set “rotation only”. (Fig. 10)

To drill a wood or metal material using the optional

drill chuck and chuck adapter, proceed as follows.

Installing drill chuck and chuck adapter: (Fig. 12)

(1) Attach the drill chuck to the chuck adaptor.

(2) The part of the SDS-plus shank is the same as the

drill bit. Therefore, refer to the item of “Mounting

the drill bit” for attaching it.

CAUTION

⅜ Application of force more than necessary will

not only expedite work at all, but will deteriorate

the tip edge of the drill bit and reduce the

service life of the rotary hammer in addition.

⅜ Drill bit may snap off while withdrawing the

rotary hammer from the drilled hole. For

withdrawing, it is important to use a pushing

motion.

⅜ Do not attempt to use the rotary hammer in the

rotation and striking mode with the drill chuck

and chuck adapter attached. This would seriously

shorten the service life of every component of

the machine.

4. When driving wood screws (Fig. 13)

(1) Selecting a suitable driver bit

Employ plus-head screws, if possible, since the driver

bit easily slips off the heads of slotted-head screws.

When using a rotary hammer for upward drilling

operations attach a dust cup or a dust collector (B)

to collect dust or particles for easy operation.

⅜ Installing the dust cup

Use the dust cup by attaching to the drill bit as

shown in Fig. 7.

When using a bit which has big diameter, enlarge

the center hole of the dust cup with this rotary

hammer.

⅜ Installing dust collector (B)

When using dust collector (B), insert dust collector

(B) from the tip of the bit by aligning it to the

groove on the grip. (Fig. 8)

CAUTION

⅜ The dust cup and dust collector (B) are for exclusive

use of concrete drilling work. Do not use them for

wood or metal drilling work.

⅜ Insert dust collector (B) completely into the chuck

part of the main unit.

⅜ When turning the rotary hammer on while dust

collector (B) is detached from a concrete surface,

dust collector (B) will rotate together with the drill

bit. Make sure to turn on the switch after pressing

dust cup on the concrete surface. When using dust

collector (B) attached to a drill bit that has more

than 190 mm of overall length, dust collector (B)

cannot touch the concrete surface and will rotate.

Therefore, please use dust collector (B) by attaching

to drill bits which have 166 mm, 160 mm, and 110

mm overall length.

⅜ Dump particles after every two or three holes when

drilling.

⅜ Please replace the drill bit after removing dust

collector (B).

4. Selecting the driver bit

Screw heads or bits will be damaged unless a bit

appropriate for the screw diameter is employed to

drive in the screws.

5. Confirm the direction of bit rotation (Fig. 9)

The bit rotates clockwise (viewed from the rear

side) by pushing the R-side of the push button.

The L-side of the push button is pushed to turn the

bit counterclockwise. (See Fig. 9) (The

and

marks are provided on the body.)

CAUTION

The push button cannot be switched while the

power tool is turning. To switch the push button,

stop the power tool, then set the push button.

6. Continuous drilling

The number of holes that can be drilled in concrete

after one recharge is shown in Table 4.
