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 lock-on button 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 the lock-on button will release.

2.In some cases, it is necessary to thrust 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.

3.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.

NOTE:

Sometimes the tool does not begin the striking motion even when the motor rotates because the oil has become thick.

If the tool is used at low temperatures or if it is used after being idle for a long time, the tool should be run for five minutes in order to warm it up.
