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 possible.
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, the use of 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
When using dull tool bits this 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 can
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.
4.
Inspecting the carbon brushes
The motor contains carbon brushes that are consumable parts; since an excessively
worn carbon brush could result in motor trouble, replace the carbon brush. Wear limiter
(6) No of carbon brush (7). (See Fig 5)
