APPLICATIONS
This demolition hammer should be applied to breaking
concrete, chipping off concrete, grooving, bar cutting and
driving piles in installation of piping and wiring, sanitary
facility installation, machinery installation, water supply
and drainage work, interior jobs, harbor facilities and
other civil engineering work.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the
nameplate of this demolition hammer.
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, this demolition
hammer will start operating immediately, inviting
serious accident.
3. Extension cord
When the work area is remote 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 an accessory, such as a bull point, a
cutter, etc.
(1) With the retainer directed backward, insert the
accessory shank point into the hole on the front
cover. (Fig. 1)
(2) Swing the retainer back into place so that it engages
the accessory shank point and prevents the
accessory, such as a bull point, a cutter, etc. from
coming all the way out of front cover. (Fig. 2)
NOTE
Use a manual hammer to open/close the retainer,
as it is too heavy to move by hand.
When removing the accessory, such as a bull point,
a cutter, etc., follow the above procedure in reverse
order.
5. Always hold the body handle and side handle of
this demolition hammer firmly.
Otherwise the counterforce produced may result in
inaccurate and even dangerous operation.
OPERATION
1. Pull 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 stroke.
This is not due to malfunction of the power tool.
It means that the safe guard mechanism against
no-load striking is working.
