6.4.2
Jack Instructions (continued)
5. Hydraulic rams must extend in order from largest to smallest diameter.
6. Largest diameter hydraulic ram must fully extend before the next stage ram begins to rise.
7. Lower mechanical ram locknut(s) while extending rams. Keep within 1 inch from bottom of extending ram
8. Do not continue to operate hand 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 with smallest ram (1
” max) until stage is
completely lowered. Repeat for next largest stage.
4. Loosen pump release valve slightly to slowly lower aircraft.
NOTE: When using jack during washing operations, completely cover top of jack near ram seal.
CAUTION!
Do not place hands on top of jack near ram locknuts while lowering jack. Pinch points exist between top of
jack and threads on ram.
Always wear safety glasses.
7.0 TRAINING
Training of operating personnel is the responsibility of the employer. This jack must be used in accordance with aircraft
manufacturer’s instructions.
8.0 MAINTENANCE
8.1 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.
NOTE: Lubricate cylinder, ram(s) and o-ring(s) for assembly:
Lubricate inner cylinder wall(s) with MIL-PRF-5606 hydraulic fluid
Apply suitable o-ring lubricant grease to installed o-ring(s) and to o-ring lead-in chamfer at opening of
cylinder

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.
8.2
SERVICING JACK
90-Day Routine Maintenance
If jack is not being used on a regular basis, every 90 days the jack should be fully extended and retracted to exercise the seals
and to prevent rust build up on the cylinder I.D. While ram is extended, clean the threads and spray with DoALL RPM, LPS, or
equivalent that is water repellent and will not harm BUNA “N” O-rings.
To Disassemble Jack for Seal Replacement:
1. Raise first stage ram high enough to allow removal of the threaded tube stop.
2. Raise both first and second stage rams
together to the point where this assembly can be lifted from the jack cylinder.
NOTE: If the second stage ram is allowed to precede the first stage ram, it will fill with oil causing an oil spill when
the assembly is removed from the cylinder.
