receptacle, the green (or green and yellow) conductor in the cord is the
grounding wire. Never connect the green (or green and yellow) wire to
a live or neutral terminal.
3) Power switch
Ensure that the power switch is in the off position before any work is
carried out on the chisel. If the plug is connected to a power receptacle
while the power switch is in the on position, the power tool will start
operating immediately this could invite serious injury.
4) Extension cord
When the work area is away from the power source, use an extension
cord of sufficient thickness and rated capacity. The extension cord
should be kept as short as practicable.

HOW TO USE THE ELECTRIC HAMMER CHISEL
Place the bit you are going to use to do the job in hand as in page 11.
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 safe guard 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, the use of too much force will
impair efficiency.
