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.
