HOW TO USE THE DEMOLITION HAMMER

1. After placing the tip of the accessory, such as a bull point,

 

etc. 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

 

accessory, such as a bull point, a cutter, etc. against the

 

crushing position forcibly in order to begin the striking

 

motion.

 

This is not due to malfunction of this demolition hammer. It

 

means that the safe guard mechanism against no-load

 

striking is working.

 

3. By utilizing the empty weight of this demolition hammer

 

and by firmly holding this demolition hammer by both hands,

Fig. 7

you can effectively control the subsequent recoil motion.

 

Proceed at a moderate work-rate, the use of too much

 

pushing force will impair efficiency.

 

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