b) Setting the hole-drilling depth.

Move the stopper to determine the stroke. The

stroke is the hole-drilling depth (see Fig. 12).

䡬 The maximum hole-drilling depth when using the

dust-collecting adapter is 100 mm.

䡬 It is possible when using the dust-collecting

adapter to use HITACHI drill bits up to a overall

length of 216 mm. A hole-drilling depth of 45 mm

will allow dust-collecting when the overall length

of the drill bit is 116 mm.

(3) Drilling holes

When drilling holes, secure the main unit so that the

end of the dust-collecting adapter contacts with the

concrete surface perfectly during drilling. Dust-

collecting effectiveness is reduced if the adapter is

not in contact with the surface (see Fig. 13).

(4) Removing dust

Excessive dust in the dust bag will reduce dust-

collecting effectiveness. Remove dust from the dust

bag regularly.

Remove the dust bag from the main unit, pull out the

rail and throw away the dust and clean (see Fig. 14).

4. When not using the dust-collecting adapter

When removing the dust-collecting adapter and the

dust bag to use as a normal rotary hammer, insert

the provided cap in the hose attachment hole. (see

Fig. 15). After removing the dust bag, the air blowing

out from the attachment hole is reduced and no air

will blow onto your face.

5. Rotation only

Remove the dust-collecting adapter as it cannot be

used. Insert the provided cap in the hose attachment

hole.

This rotary hammer can be set to rotation only mode

by pussing the push button and turning the change

lever to the

mark (Fig. 16).

To drill wood or metal material using the drill chuck

and chuck adapter (optional accessories), proceed as

follows.

Installing drill chuck and chuck adapter: (Fig. 17)

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

(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:

䡬 Application of force more than necessary will not

only expedite the work, but will deteriorate the tip

edge of the drill bit and reduce the service life of the

rotary hammer in addition.

䡬 Drill bits may snap off while withdrawing the rotary

hammer from the drilled hole. For withdrawing, it is

important to use a pushing motion.

䡬 Do not attempt to drill anchor holes or holes in

concrete with the machine set in the rotation only

function.

䡬 Do not attempt to use the rotary hammer in the

rotation and striking function with the drill chuck and

chuck adapter attached. This would seriously shorten

the service life of every component of the machine.

6. When driving machine screws (Fig. 18)

First, insert the bit into the socket in the end of chuck

adapter (D).

Next, mount chuck adapter (D) on the main unit

using procedures described in 4 (1), (2), (3), put the

tip of the bit in the slots in the head of the screw,

grasp the main unit and tighten the screw.

1. Switch operation

The rotation speed of the drill bit can be controlled

steplessly by varying the amount that the trigger

switch is pulled. Speed is low when the trigger switch

is pulled slightly and increases as the switch is pulled

more. Continuous operation may be attained by

pulling the trigger switch and depressing the stopper.

To turn the switch OFF, pull the trigger switch again

to disengage the stopper, and release the trigger

switch to its original position.

However, the switch trigger can only be pulled in

halfway during reverse and rotates at half the speed

of forward operation.

The switch stopper is unusable during reverse.

2. Rotation + hammering

This rotary hammer can be set to rotation and

hammering mode by pressing the push button and

turning the change lever to the

mark (Fig. 6).

(1) Mount the drill bit.

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

the drilling position (Fig. 7).

(3) Pushing the rotary hammer forcibly is not necessary

at all. Pushing slightly so that drill dust comes out

gradually is sufficient.

CAUTION:

When the drill bit touches construction iron bar, the

bit will stop immediately and the rotary hammer will

react to revolve. Therefore grip the side handle and

handle tightly as shown in Fig. 7.

3. Using the dust-collecting adapter and dust bag

Using this unit with the dust-collecting adapter and

dust bag attached creates a more hygienic working

environment free of flying dust. Attach as shown in

Fig. 8. The unit can be used as an ordinary rotary

hammer when the dust-collecting adapter and dust

bag are not attached.

(1) Attaching the dust-collecting adapter and the dust

bag.

a) Attaching the dust-collecting adapter.

Loosen the knob on the side handle and insert the

attachment rod on the dust-collecting adapter in

the mounting hole.

The adapter can be inserted from either direction

A or B (see Fig. 9). Insert and push in the hose in

the hose attachment hole of the main unit until it

reaches the inner surface (depth 15 mm) and

confirm that it is firmly fixed (see Fig. 10).

b) Attaching the dust bag.

Insert the dust bag firmly in the dust bag

attachment hole on the main unit and fasten

securely (see Fig. 11).

CAUTION

䡬 The dust-collecting adapter and dust bag is made

for use when drilling concrete. Do not use for

drilling holes in metal or wood.

(2) Adjusting the dust-collecting adapter.

a) Adjusting the position of the dust-collecting

adapter.

After firmly inserting the drill bit, loosen the wing

bolt and drill bit tip and the end of the dust-

collecting adapter in contact with each other (see

Fig. 12).
