MAINTENANCE AND SERVICE
3.Power s
witch
Ensure t
hat 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
source
while the power switch is in the on position, the
power tool will start operating immedia
tely this
could invite serious injury.
4.Extensi
on cord
When th
e work area is away from the power
source, us
e an extension cord of sufficient
thickness and rated capacity. The extension cord

How to
use the electric hammer chisel
Place the bit you are going to use to do the job in
hand as i
n 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. 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.
Oil feeding
Caution. Prior to oil feeding, always disconnect
the plug from the power supply
source
. 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.
