HOW TO USE THE DEMOLITION
HAMMER
1. Pull the trigger switch after applying the tip of the
bit to the crushing position.
2. Operate this demolition hammer by utilizing its own
weight. The performance will not be better even if
it is pressed or thrust forcibly against the work
surface. Hold this demolition hammer with a force
just sufficient to counteract the reaction.
This demolition hammer is equipped with a spring
cushion on the handle so that chipping vibration is
not conveyed to the operator.
Operate this demolition hammer without forcing the
handle too strongly.
