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. Refer to the preceding table. Standard
units are supplied with automatic transmission fluid
(ATF), and arctic units are supplied with long life
synthetic hydraulic fluid.
PRIMING THE HYDRAULIC PUMP
Pumps that have been disassembled for repair, or
pumps that have been replaced require proper priming
to avoid possible pump failure. A pump is said to be
“primed” when the internal portions of the pump are
filled with oil and all air has been expelled.
To prime the hydraulic pump:
1
Make sure that the oil reservoir is filled with oil to the
full mark.
2 Place a catch pan under the pump to catch excess oil.
3
Loosen the hose end to allow oil and air to escape.
4 Turn on the ignition switch and move the tower raise
/ lower switch to the “raise” or up position. Do so
intermittently, or “jog” the pump. This will expel air
and oil through the loosened fitting. Repeat until oil
flow is free of air.
5
Re-tighten the hose end. Turn off the ignition switch.
6 Remove the catch pan and dispose of the oil
following the guidelines of governmental agencies.
7
Replenish the oil in the reservoir to the full mark.

Reservoir
Once the pump has been primed, the cylinder should
be purged of air. To purge the cylinder of air:
1
Make sure that the oil reservoir is filled with oil to the
full mark.
2
Clean the bleeder fitting on the upper end of the
cylinder barrel.
3
Place a bleeder hose over the end of the bleeder
fitting. Place the other end of the bleeder hose in a
suitable catch container.
4
Turn on the ignition switch and move the tower raise
/ lower switch to the “raise” or up position.
5
Open the bleeder fitting. Allow oil and air to bleed
out of the cylinder. Close the bleeder when oil flow is
free of air.
6
Remove the catch container and the bleeder hose.
Dispose of the oil in the catch container following
the guidelines of governmental agencies.
7
Move the tower raise / lower switch to the “lower” or
down position. Be sure that the tower is fully
lowered. Turn off the ignition switch.
8
Replenish the oil in the reservoir to the full mark.
