APPLICATIONS
Demolishing concrete, chiseling off concrete, grooving,
bar cutting.

Installation of piping and wiring, sanitary facility
installation, machinery installation, water supply and
drainage work, interior jobs, harbor facilities and other
civil engineering works.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the
power switch is in the ON position, the power tool
will start operating immediately, which could cause
a serious accident.
3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Mounting a tool
NOTE:
For tools such as a bull point and a cold chisel,
use only genuine HITACHI parts.
(1) Clean, then smear the tool shank with grease or
machine oil. (Fig.1)
(2) Rotate the stop lever 180° in a clockwise direction
while pulling it toward you. Next, insert the tool
shank into the hexagonal hole on the frontcover.
(Fig.1)
(3) Clamp the tool by turning the stop lever by half
a turn in the opposite direction. (Fig. 2)
HOW TO USE THE DEMOLITION HAMMER
1. Squeeze the trigger switch after applying the tip of
the bit to the crushing position.
In some cases, it is necessary to punch the tip of
the bit against the crushing position forcibly in
order to begin the striking motion.
This is not due to malfunction of the tool. It means
that the safe guard mechanism against no-load
striking is working.
2. Operate the tool by utilizing its empty weight. The
performance will not be better even if the tool is
pressed or thrust forcibly against the work surface.
Hold the tool with a force just sufficient to counteract
the reaction. (Fig. 3)
