(1) Mount the drill bit.
(2) Pull the trigger switch after applying the
drill bit tip to the drilling position (Fig. 5)
(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 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. 5.
3. Rotation only
This rotary hammer can be set to
rotation only mode by pressing the
push button and turning the change
lever to mark. (Fig. 6)
Turn the grip slightly and confirm that
the clutch has been engaged with a
click.
To drill a wood or metal material using
the separately sold drill chuck and chuck
adaptor, proceed as follows. Installing
drill chuck and chuck adaptor (Fig. 7):
(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:
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.
Drill bit 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 main unit in
the rotation only function.
Do not attempt to use the rotary hammer in the rotation and hammering func-
tion with the drill chuck and chuck adaptor attached. This would seriously
shorten the service life of every components of the machine.
