Information on how to use the electric hammer chisel
Prior to operation
1. Power source Ensure that the power source to be utilized conforms to the power requirements specified
on the product nameplate.
2. 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.
3. 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 Fig 2
(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.
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.
CLEANING AND MAINTANCE
Oil feeding
Caution!
Prior to oil feeding, always disconnect the plug from the power supply receptacle. Since an oil chamber is
built in this electric hammer chisel, it can be used for approximately 20 days without supplying lubrication
oil, assuming that the chisel is used continuously 3–4 hours daily.
Feed oil into the oil tank as described below before using the hammer chisel.
(1) When the chisel is held upright look through the oil gauge window to see if oil is visible, if no oil shows
oil must be installed before operating.
If chisel is used without oil this could seriously damaged the chisel and forfeit any warranty given.
(2) Before feeding oil, use the provided wrench to remove the oil gauge (4). Be careful not to lose the
rubber packing attached below the oil gauge.
(3) Check the oil level once daily, confirming that oil is filled.
(4) After feeding oil, securely clamp the oil gauge.
Note: Oil for the electric hammer chisel is sold separately, use Shell oil ROTELLA 40 (engine oil) or
equivalent, this is sold at most shops or filling stations anywhere.
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 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
