How to use the electric hammer chisel
Place the bit you are going to use to do the job in your hand as in Fig 3 and 4
1. Pull the trigger switch after applying the chisel bit tip to the chiseling position.
2. It may be necessary to punch the bit against the crushing position forcibly in order to begin the
striking stroke. This is not due to malfunction of the tool, it means that the safeguard
mechanism against no-load striking is working.
3. By utilizing the weight of the machine and by firmly holding the hammer chisel with both hands,
one can effectively control the subsequent recoil motion.
Proceed at a moderate work rate, using too much force will impair efficiency.
Caution
Sometimes the tool does not begin the striking stroke even when the motor rotates. This may be
because the oil has become thick (due to low temperatures or if the power tool has not been used for a
long time). Run the chisel for approximately 5 minutes to bring the oil temperature up.

Maintenance and inspection
1. Inspecting the tool
Using dull tool bits can cause motor malfunction and degraded efficiency. Always replace dull
bits with new ones without delay when abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened. Should any
of the screws be loose, retighten them immediately. Failure to do so could result in serious
injury.
3. Maintenance of the motor
The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the
winding does not become damaged and/or wet with oil or water.
