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 backup 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 2.629 in (66.78 mm) 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.
9.2.1
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
SERVICING JACK
To Disassemble Jack:
1. Remove mounting plate (Item 63) by unscrewing three socket head cap screws (Item 57).
2. Raise ram assembly (Item 59) to the point where it can be lifted from the jack cylinder.
To Re-assemble Jack:
Re-assemble in reverse order of above.
NOTES:
Dispose of hydraulic fluid per local and federal regulations.
To minimize air entrapment under the ram, raise the oil level in the cylinder to chamfer of the cylinder prior to
ram insertion.
Torque socket head cap screws (Item 57) to 35 ft-lbs (47 Nm)
9.4
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-1753 Hand Pump Parts List.
2. Clamp suction (push on) hose and remove hose from pump.
3. Uncouple fitting of hydraulic hoses from pump.
4. Remove pump from jack.
5. Remove cotter pin from clevis pin.
6. Remove four (4) socket head cap screws.
7. Remove flanges.
8. Remove tube assembly.
9. Replace O-rings and backup ring. (See Appendix III for kits available.)
