from drill rear.
7. How to install tool
CAUTION:
For tools such as a bull point and a cold chisel,
use only Hitachi genuine parts.
(1) Clean, then smear the tool shank with the
grease provided.
(2) Slide the tool holder in the direction of arrow
A and rotate it 180˚.
Turn the notch of the tool shank downward and
insert it fully into the hexagonal hole of the
front cover. (Fig. 3)

HOW TO USE

1. How to drill holes (Fig. 4)
(1) Use the Bar type handle.
Do not use D type handle when drilling
operation, since it may not be enough to hold
the body firmly.
(2) Pull the switch trigger after applying the drill
bit tip to the drilling position.
(3) 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 bar type handle are
gripped firmly during operation.
