HOW TO USE

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 fi rmly during operation.

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.
