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.

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 faulty receptacle is used, it may cause
overheating, resulting in a serious hazard.
Confirming condition of the environment:
Confirm that the work site is placed under
appropriate conditions conforming to prescribed
precautions.
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.
By utilizing the empty weight of the machine and
by firmly holding the demolition hammer with both
hands, one can effectively control the subsequent
recoil motion.
Proceed at a moderate work-rate, the use of too
much force will impair efficiency.
