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 ON-Lock switch is pressed while the trigger for
the switch is pulled, even if your fi nger 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 ON-Lock switch comes off .
2. By utilizing the empty weight of the machine and by
fi rmly holding the hammer by 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.
3. Even when the switch is on, the motor is running and
the tool head is pressed to the demolition surface,
the hammer sometimes does not start operating. In
these instances, turn the switch off , press the tool
head against the demolition surface again, and turn
the switch on and off . This should start the hammer
operating. Repeat this procedure for several minutes,
and the hammer will heat, after which it will operate
when switched to ON-LOCK.
4. Warming up (Fig. 9)
The grease lubrication system in this unit may require
warming up in cold regions.
Position the end of the bit so makes contact with the
concrete, turn on the switch and perform the warming
up operation. Make sure that a hitting sound is
produced and then use the unit.
