FIGURE 1

5.0 OPERATING INSTRUCTIONS

The user should be familiar with the following statements prior to using the jack(s).

CAUTION!

1. Jacking adapters must be fully seated on mechanical extension.

2. Never put hands between aircraft and jack pad.

3. Always open reservoir vent screw before operating.

5.1 JACK INSTRUCTIONS

To Raise Nose Gear:

1. Place jack on hard level surface.

2. Connect pump hose to three-stage ram.

3. Open reservoir vent screw.

4. Screw out mechanical extension.

5. Close pump release valve and operate

pump.

To Raise Main Gear:

1. Place jack on hard level surface.

2. Connect the pump hose to two-stage ram.

3. Open the reservoir vent screw.

4. Adjust mechanical extension so the pad is

approximately one-quarter inch (0.25 in/0.63 cm) below the

bottom of the jack pad on the aircraft.

5. Place the jack between the tires and check the clearance

between the mechanical extension and the bottom of the jack

pad.

6. Measurement should be approximately one-quarter inch

(0.25 in/0.63 cm).

7. Close pump release valve and slowly begin to pump the jack to raise the aircraft wheel. Verify that there is clearance

between the jack cylinder assembly and the brake casting.

6.0 MAINTENANCE

6.1 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 MIL-PRF-5606 hydraulic

fluid.

No modifications shall be carried out which adversely affect the compliance of the jack with draft standard 98/37/EC.

6.2 SERVICING JACK

(Reference Parts List Illustrations during the following procedures.)

To Disassemble Jack:

1. Collapse jack ram.

2. Remove cap screws (Items 26 & 28) surrounding jack cylinder, then remove retaining rings, (Items 27 & 29).

3. Lift cylinder from axle jack base (Item 30). Operate jack hand pump to help remove cylinder.

4. Separate three-stage rams by removing internal rings (Items 6, 7 &8).

5. Separate two-stage rams by pushing second stage ram through bottom of cylinder. Unscrew first stage piston end cap

and pull out second stage piston end cap.

To Re-assemble Jack:

1. Replace all seals including internal rings.

2. Re-assemble in reverse order of above.

3. Torque each cap screw (Item 26) to 30 ft-lb (40.67 N-m) and Item 28 to 50 ft-lb (67.79 N-m) using standard cross torque

procedure.
