4. When not using the dust-collecting
adaptor
When removing the dust-collecting
adaptor and the dust bag to use as a
normal rotary hammer, insert the pro-
vided cap in the hose attachment hole.
(see Fig.14) After removing the dust
bag, the air blowing out from the at-
tachment hole is reduced and no air will
blow onto your face.
5. Rotation only
Remove the dust-collecting adaptor as
it cannot be used. Insert the provided
cap in the hose attachment hole.
The rotary hammer can be set to rota-
tion only mode by rotating the change
lever fully clockwise to mark. (Fig. 15)
To drill a wood or metal material using
the separately sold drill chuck and
chuck adaptor, proceed as follows. In-
stalling drill chuck and chuck adaptor
(Fig. 16):
(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 effi-
ciency 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 striking function
with the drill chuck and chuck adaptor attached. This would seriously shorten
the service life of every components of the machine.
