How to use the electric hammer chisel
Place the bit you are going to use to do the job in 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
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. (See Fig 5
)
Proceed at a moderate work rate, the use of too much force will impair efficiency.
Fig 5
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 temperature or has been standing idle for long period. Run the chisel for
approx 5 minutes to bring the oil temperature up.
Be prepared for binding and bit breakthrough. When these situations occur, the chisel
bit has the tendency to grab the workpiece.
This action will kick the chisel opposite to the direction of chisel bit rotation and could
cause loss of control when breaking through material as you complete chiseling the
hole.
If you are not prepared, this loss of control can result in possible serious injury.
