exist between top of jack and threads on ram.
•
Always wear safety glasses.

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 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 inches
(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 manufacturers 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 prEN 1494:1994.
