regulate the number of rotations and times of
hammering. This Rotary Hammer can be used by
adjusting the dial, depending upon the contents
of operation, such as boring holes into fragile
materials, chipping, centering, etc.
The scale '1' of the dial is designed for a minimum
speed with the number of 110 rotations per minute
and 1,050 times of blow per minute. The scale '6'
is designed for a maximum speed with the number
of 230 rotations per minute and 2,150 times of blow
per minute.
CAUTION:
Do not adjust the dial during operation. Doing so
can result in injury because the Rotary Hammer
must be held by only one hand, disabling the
steady control of the Rotary Hammer.

HOW TO USE

1. How to drill holes (Fig. 4)
(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.
