HOW TO USE THE DEMOLITION HAMMER

1. Switch operation
The switch turns ON when it is pulled, and turns OFF
when it is released.
While the switch is pulled all the way, if the push
button is pushed toward "A", the switch becomes
locked and stays ON even if your fi nger releases it,
enabling continuous operation. (Fig. 7)

2. After placing the tip of the accessory, such as a bull
point, etc. on a concrete surface, turn the switch ON.
The trigger switch turns ON when it is pulled and turns
OFF when it is released.
3. 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.
4. By utilizing the empty weight of this demolition
hammer and by fi rmly holding the demolition hammer
with both hands, you can eff ectively control the
subsequent recoil motion.
Proceed at a moderate work-rate. The use of too
much pushing force will impair effi ciency.
