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 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.
CAUTION: After long time of use, the cylinder case becomes hot.
Therefore, be careful not to burn your hands.
