(1) Mount the drill bit.
(2) Pull the trigger switch after applying the drill bit tip
to the drilling position (Fig. 8)
(3) Pushing the rotary hammer forcibly is not necessary
at all. Pushing slightly so that drill dust comes out
gradually is just sufficient.
CAUTION:
䡬
When the drill bit touches an iron reinforcing rod,
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.
8.
3. Rotation only
This rotary hammer can be set to rotation only
mode by turning the change lever to the mark
(Fig. 9).
To drill a wood or metal material using the
separately sold drill chuck and chuck adaptor,
proceed as follows. Installing drill chuck and chuck

(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:
䡬
Application of force more than necessary will not
only reducing drilling efficiency at all, but will
deteriorate the tip edge of the drill bit and reduce
the service life of the rotary hammer in addition.
䡬
Drill bit 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 main unit 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 adaptor attached. This would seriously
shorten the service life of every components of the
machine.
4. When driving machine screws (Fig. 11)
First, insert the bit into the socket in the end of chuck
adaptor (D).
Next, mount chuck adaptor (D) on the main unit
using procedures described in 5 (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.
CAUTION:
䡬
Exercise care not to excessively prolong driving
time, otherwise, the screws may be damaged by
excessive force.
䡬
Apply the rotary hammer perpendicularly to the
screw head when driving a screw; otherwise, the
screw head or bit will be damaged, or driving force
will not be fully transferred to the screw.
䡬
Do not attempt to use the rotary hammer in the
rotation and striking function with chuck adaptor
(D) and bit attached.
