DC Motor.
DC motor - The DC motor can be removed without
worrying about oil spillage. Just remove the 2 long
bolts
(1)
at the end of the motor. You can now
withdraw the motor. Take care not to strain the wires.
To ensure optimum performance from the DC motor
we recommend replacing the motor brushes when
they are 2/3 worn. If the machine is used extensively
(quite normal in a hire environment) this can be
required at least every 6 months. To replace the
brushes, fully remove the motor from the power pack.
Blow out all the brush dust using compressed air
before reassembling the motor.
Check the motor shaft bearing and replace if worn.
We also recommend replacing the contactor at the
same time as replacing the brushes. The unit is fully
sealed (to prevent sparks igniting battery gases) and
contain no serviceable parts.
If the motor is not stopping when the green motor run
button is released and no power is at the contactor
coil. Replace contactor immediately. To stop the
motor in this case. Use the battery disconnect plug or
lightly tap the contactor on its end
(2)
with the handle
of a large screw driver to free the internal contact
points
IMPORTANT
The main relief valve is factory set at 210 bar and should normally not need
adjusting. Breaking the seal (3) during the warranty period, for whatever rea-
son, will invalidate the warranty.

When the pump has been removed it can be split and the gears can be inspected for wear. If
the gears are worn (or broken) we recommend replacing the complete pump. The
replacement pump is complete with gears, front and back plate all ready to bolt on in place of
the old unit (strainer is not included). Before fitting the pump, apply a liberal amount of clean
hydraulic oil to the gears. Take great care to torque the 4 - 5/16 Hex fixing bolts evenly to 13
ft/lbs to ensure correct operation of the pump.
DO NOT OVERTIGHTEN
. Before fitting the
tank. Thoroughly clean the tank and the magnet you will find inside the tank. De-grease,
replace the large “O” ring and apply a small amount of silicone around the circumference of
the de-greased tank neck. Push the tank back on and secure with the 4 bolts removed
earlier .
