hydraulic cylinder maintenance

Check the fluid level every month.Fill the reservoir with the jacks in the fully retracted position. The fluid should be within 1/4 inch of the fill port lip and checked only with all jacks retracted.Hydraulic slideout systems should be checked the same way,retract all slides before adding fluid.

If jacks are down for extended periods, it is recommended to spray exposed chrome rods with a silicone lubricantevery seven days for protection. If your coach is located in a salty environment (within 60 miles of coastal areas), it is recommended to spray the rods every 2 to 3 days.

Jacks equipped with grease fittings at the bottom of the cylinder should be greased with a light weight lithium greaseusing a hand pump style grease gun only. 2 or 3 pumps should be sufficient for 20-30 uses.

Inspect and clean all hydraulic pump electrical connections every 12 months.

Remove dirt and road debris from jacks as needed.

Change fluid every 24 months
