HOW TO USE

How to drill holes (Fig. 5)

the rotary hammer to an extent that clips are freely
discharged.
CAUTION:
Although this machine is equipped with a slip
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 demolish (Fig. 6)
By applying the tool tip to the chiseling or
demolishing position, operate the rotary hammer
by utilizing its empty weight. Forcible pressing or
thrusting is unnecessary.
