HOW TO USE
1. How to drill holes (Fig. 5)
(1) Pull the switch trigger after applying the drill
bit tip to the drilling position.
(2) It is unnecessary to forcibly press the Rotary
Hammer main body. It is sufficient to slightly
press the rotary hammer to an extent that clips
are freely discharged.
CAUTION:
Although this machine is equipped with a
safety clutch, if the drill bit becomes bound in
concrete or other material, the resultant
stoppage of the drill bit could cause the
machine body to turn in reaction. Ensure that
the main handle and side handle are gripped
firmly during operation.
2. How to chisel or crush (Fig. 6)
By applying the tool tip to the chiseling or
crushing position, operate the rotary hammer
by utilizing its empty weight. Forcible pressing
or thrusting is unnecessary.
3. When drilling at “rotation + hammering”
CAUTION:
If you switch the selector lever during motor
rotation, the tool can start to rotate abruptly,
resulting in unexpected accidents. Be sure to
switch the selector lever when the motor is at
a complete stop.
(1) Switching to “rotation + hammering”
(a) Push the button, release lock and turn the
selector lever clockwise.
(b) Align
of the selector lever and of the
lever holder as illustrated in Fig. 7.
(c) Release the button to lock the selector
lever.
NOTE: Turn the selector lever (do not push the button) to check if it is completely locked
and make sure that it does not turn.
