HYDRAULIC CYLINDER MAINTENANCE
The hydraulic cylinders which operate the rear door and side door (if installed) should be
inspected before each use. See figures (19) and (20) for precautionary measures that
must be taken before performing any maintenance.
•
Repair any leaking fittings found before operating the cylinder.
•
Keep the cylinder clean and free from foreign materials.
•
If there is leakage across the cylinder or the cylinder housing or the shaft is damaged,
replace the cylinder.
•
A light film of oil on the shaft of the cylinder is normal and should not be mistaken as a
leak.
•
Small burrs or scratches should be removed from the shaft using a honing stone or
emery cloth before use of the cylinder.
