7.0 MAINTENANCE
7.1 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 all O-rings and backup rings once removed. Cut and damaged rings normally result in fluid
leakage.

At this time flush old hydraulic fluid and dirt from overall system and replenish with new, clean hydraulic fluid

No modifications shall be carried out which adversely affect the compliance of the jack with draft standard 2006/42/EC.
