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. 8)

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.

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.

(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. 10)

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)	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. 11).
