If you continue to turn the tool with slight pressure,
you can feel a spot where there is a hitch. At that
spot, pull the grip to the direction of an arrow mark
and insert the tool all the way until it hits the
innermost end.
Releasing the grip reverts the grip and secures the
tool in place.

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 demolish (Fig. 4)
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.
