PRIOR TO OPERATION
1.
Power source
Ensure that the power source to be utilized
conforms to the power source requirements
specified on the product nameplate.
2.
Power switch
Ensure that the switch is in the OFF position. If the
plug is connected to a receptacle while the switch
is in the ON position, the power tool will start
operating immediately and can cause serious
injury.
3.
Extension cord
When the work area is far away from the power
source, use an extension cord of sufficient
thickness and rated capacity. The extension cord
should be kept as short as practicable.
WARNING:
Damaged cord must be replaced or
repaired.
4.
Check the receptacle
If the receptacle only loosely accepts the plug, the
receptacle must be repaired. Contact a licensed
electrician to make appropriate repairs.
If such a fautly receptacle is used, it may cause
overheating, resulting in a serious hazard.
5.
Confirming condition of the environment:
Confirm that the work site is placed under
appropriate conditions conforming to prescribed
precautions.

OPERATION
HOW TO USE THE DEMOLITION HAMMER
1.
After placing the tip of the tool on concrete surface,
switch ON.
The switch can be turned ON if the trigger is pulled
and OFF when it is released.
If the stopper is pressed while the trigger for the
switch is pulled, even if your finger is released from
the trigger, the switch remains ON - convenient
for continuous operation.
To turn the switch OFF, pull the trigger again, and
then the stopper comes off.
2.
By utilizing the empty weight of the machine and
by firmly holding the hammer by both hands, you
can effectively control the subsequent recoil
motion.
Proceed at a moderate work-rate, the use of too
much pushing force will impair efficiency.
3.
Even when the switch is on, the motor is running
and the tool head is pressed to the demolition
surface, the hammer sometimes does not start
operating. In these instances, turn the switch off,
press the tool head against the demolition surface
again, and turn the switch on and off. This should
start the hammer operating. Repeat this procedure
for several minutes, and the hammer will heat, after
which it will operate when switched to ON-LOCK.
CAUTION:
After long time of use, the cylinder case becomes
hot.
Therefore, be careful not to burn your hands.
