5.0 OPERATING INSTRUCTIONS (continued)

5.1 JACK INSTRUCTIONS

To Raise Aircraft:

1. Place jack on a hard level surface.

2. Raise jack as close to aircraft jack pad as possible. Screw out the center mechanical extension

for final adjustment.

3. Open reservoir vent screw.

4. Close pump release valve and operate pump.

To Lower Aircraft:

6.0 MAINTENANCE

GENERAL

• All maintenance and/or repair work should be done using good workmanship practices and proper tools.

• The work area should be clean and free of dirt.

• When O-rings and backup rings are removed, every effort should be made to avoid the contact of tools

with the critical surfaces of parts. Surface deformities could cause degradation of seals and failure.

• It is good practice to replace all O-rings and backup rings once removed. Cut and/or damaged rings

normally result in fluid leakage.

• At this time flush old hydraulic fluid and dirt from overall system and replenish with new, clean hydraulic

fluid.
