7.4 OPERATING INSTRUCTIONS (continued)
7.4.3 Jack Instructions
To Raise Aircraft:
1. Place jack on a hard, level surface.
2. Hydraulic ram must be completely retracted before operating the jack.
3. Release caster levers and maneuver jack into jacking position.
4. Raise mechanical extension as close to aircraft jack pad as possible.
NOTE: Mechanical extension has a built-in mechanical stop and is limited to a 4” travel
5. Close pump release valve and operate pump.
6. Hydraulic rams must extend in order from largest to smallest diameter.
7. Largest diameter hydraulic ram must fully extend before the next stage ram begins to raise.
8. Lower mechanical ram locknut(s) while extending rams. Keep within 1 inch of bottom of extending ram
9. Do not continue to operate air pump after all rams have fully extended.
WARNING!
The ram locknuts are user operated safety devices. Failure to utilize these locknuts may result in personal
injury or death and/or damage to aircraft or equipment.
To Lower Aircraft:
1. Lower all jacks simultaneously.
2. If ram locknut(s) is tight, raise jack slightly to release nut(s) ¼ inch from tripod.
3. Ensure proper staging as aircraft is being lowered: loosen ram locknut beginning wih smallest ram (1 inch max) until stag
is completely lowered. Repeat for next smallest stage.
4. Loosen pump release valve slightly to slowly lower aircraft.
5. Lock caster levers and remove jack from aircraft.
NOTE: When using jack during washing operations, completely cover top of jack near ram seal.

8.0 TRAINING
Training of operating personnel is the responsibility of the employer. This jack must be used in accordance with aircraft
manufacturer’s instructions.
9.0 MAINTENANCE
9.1 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 both O-rings and back-up rings once removed. Cut and damaged O-rings normally result in
fluid leakage.
If cylinder bore is found to be rusty, it may be honed to a maximum diameter of .002 in (.05 mm) over on diameter and a
surface finish of 16 micro inches. If pitting in the bore cannot be removed by this process, the jack cylinder must be
replaced before the jack can be returned to service.
At this time, flush old hydraulic fluid and dirt from overall system and replenish with new, clean hydraulic fluid.
When refilling the hydraulic system the characteristics of the hydraulic fluid used in the jack and the level of the hydraulic
fluid as it is noted on the jack shall be observed.
Jacks shall be maintained and repaired in accordance with the manufacturer’s instructions. Such maintenance and repair
shall be carried out by qualified persons.
No modifications shall be carried out which adversely affect the compliance of the jack with draft standard 2006/42/EC.
9.2 MAINTENANCE SCHEDULE
Check Fluid Level................................................................Each Use
Lubricate Casters................................................................3 Months
Cleaning..............................................................................Annually Or As Needed
Capacity Test (105%-110% of jack’s rated capacity) ..........Annually
NOTE: Wipe with soft cloth only, do no pressure wash or spray water directly at ram seal.
9.2 Maintenance schedule continued on following page.

10/2012 | Rev. 02 Page | 7
9.2 MAINTENANCE SCHEDULE (continued)
9.2.1 Storage/Low Usage
If jack is unused for 90 days, raise ram to full hydraulic extension, spray ram with DoALL RPM, LPS or equivalent water
repellant, BUNA N compatible lubricant.
9.3 REMOVING AND SERVICING PUMP
NOTE: If pump is found faulty, call the factory for replacement or replace seals as follows:
1. Review Appendix III HC-1961 Hand Pump Parts List.
2. Clamp suction (push on) hose and remove hose from pump.
3. Uncouple fittings of hydraulic hoses from pump.
4. Remove pump from jack.
5. Remove cotter pin from clevis pin.

7. Remove flanges.
8. Remove tube assembly.
9. Replace O-rings and backup ring. (See Appendix III for kits available.)
10. Re-assemble in reverse order.
9.4 JACK FUNCTION LOAD TEST
NOTE: If function load testing is required:
1. Take all necessary precautions to prevent injury.
2. Always jack against a load and never against the jack itself.
3. Do not exceed a test load equal to the jack rated capacity plus 10%.
9.5 PNEUMATIC PUMP
