To operate the change lever, press the push button, and release the lock of the change lever. Also, check and make sure after operation that the push button has returned and that the change lever has been locked.

Switch the change lever without mistake. If it is used at a position halfway, there is a fear that the service life of the switching mechanism may be shortened.

HOW TO USE

CAUTION:

To prevent accidents, make sure to turn the switch off and disconnect the plug from the receptacle when the drill bits and other various parts are installed or removed. The power switch should also be turned off during a work break and after work.

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.

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. 3).

Turn the grip slightly and confirm that the clutch has been engaged with a click.

(1)Mount the drill bit.

(2)Pull the trigger switch after applying the drill bit tip to the drilling position. (Fig. 4)

(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. 4.

3.Rotation only

This rotary hammer can be set to rotation only

mode by pussing the push button and turning the

change lever to the mark. (Fig. 5)

Turn the grip slightly and confirm that the clutch has been engaged with a click.

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. 6)

(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.

CAUTIONS:

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.

Drill bits may snap off while withdrawing the rotary hammer from the drilled hole. For withdrawing, it is important to use a pushing motion.

Do not attempt to drill anchor holes or holes in concrete with the machine set in the rotation only function.

Do not attempt to use the rotary hammer in the rotation and hammering function with the drill chuck and chuck adapter attached. This would seriously shorten the service life of every component of the machine.

4.When driving machine screws (Fig. 7)

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.

CAUTIONS:

Exercise care not to excessively prolong driving time, otherwise, the screws may be damaged by excessive force.

Apply the rotary hammer perpendicularly to the screw head when driving the screw; otherwise, the screw head or bit will be damaged, or driving force will not be fully transferred to the screw.

Do not attempt to use the rotary hammer in the rotation and hammering function with the chuck adapter and bit attached.

5.When driving wood screws (Fig. 7)

(1) Selecting a suitable driver bit

Employ cross-recessed screws, if possible, since the driver bit easily slips off the heads of slotted-head screws.

(2) Driving in wood screws

Prior to driving in wood screws, make pilot holes suitable for them in the wooden board. Apply the bit to the screw head grooves and gently drive the screws into the holes.

After rotating the rotary hammer at low speed for a while until the wood screw is partly driven into the wood, squeeze the trigger more strongly to obtain the optimum driving force.

CAUTION:

Exercise care in preparing a pilot hole suitable for the wood screw taking the hardness of the wood into consideration. Should the hole be excessively small or shallow, requiring much power to drive the screw into it, the thread of the wood screw may sometimes be damaged.

6.Hammering only

This rotary hammer can be set to hammering only mode by pressing the push button and turning the

change lever to the

mark (Fig. 8).

(1)Mount the bull point or cold chisel.

(2)Press the push button and set the change lever to mark. (Fig. 9)

The rotation is released, turn the grip and adjust the cold chisel to desired position. (Fig. 10)

(3)Turn the change lever to mark. (Fig. 8) Then bull point or cold chisel is locked.

7. Using the stopper (Fig. 11)

(1)Loosen the side handle, and insert the stopper into the handle bolt hole.

(2)Adjust the stopper position according to the depth of the hole and thighten the side handle securely.
