MAINTAINING THE HYDRAULIC PUMP
HYDRAULIC FLUID SPECIFICATION
ADDING HYDRAULIC FLUID
Fill the reservoir with aviation hydraulic fluid or any
clean hydraulic fluid having a viscosity index that is
suitable for the climate conditions in which the unit will
be operated. Standard units are supplied with
automatic transmission fluid (ATF), and arctic units are
supplied with aviation hydraulic fluid.
PRIMING THE HYDRAULIC PUMP
The ports are marked UP and DN on the hydraulic
power unit casting.
To prime the hydraulic pump:
1 When facing the power unit with the motor up, plug
the DN (right) port.
2 Jog the motor until oil flows from the UP (left) port.
3 If oil does not flow from the UP port, reverse the wire
leads on the motor and repeat. The pump is now
primed.
4 Connect the hose or tubing to the UP port and
tighten.
5 Connect the other hose end to the blind end of a fully
retracted hydraulic cylinder.
6 With the hose fitting loose, operate the power unit
until oil (and no air) bleeds from the fitting.
7 Tighten the fitting, then refill the reservoir.
MAINTAINING THE LIGHT TOWER AND
LAMPS
CHANGING LAMPS
To change the lamps:
1 Turn off the lights and shut off the engine. Allow the
bulbs and fixtures to cool.
2 Lower the light tower to the full down position.
3 Loosen the lens channel screws to allow the removal
of the lens channel.
4 Remove the silicone gasket and lens.
5 Remove the support clip screws and support clip.
6 Carefully remove the old lamp and install the correct
replacement.
7 Clean the reflector and lens.
8 Install the support clip and screws.
9 Install the silicone gasket and lens (replace if
damaged).
