This rotary hammer can be set to rotation and
hammering mode by pressing the push button and
turning the change lever to
(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 suffi cient.
CAUTION
When the drill bit touches an iron reinforcing

hammer will react to revolve. Therefore please grip
the side handle and handle tightly as shown in Fig.
8.

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.
