GENERAL MAINTENANCE
14. Check the piston head nut for tightness and torque to 600-650 ft. lbs on 3 ½”
bore cylinders or 850-950 ft. lbs. on 4” bore cylinders. The upper clevis and pin
may be used to prevent the rotation of the rod while tightening.
15. Liberally
lubricate the piston and seal with CLEAN grease or oil.
16. Reinsert the piston into the barrel, taking care not to pinch or nick the new seal.
17. Slip the bearing assembly into place and align the retainer hole with the slot in
the barrel.
18. Turn the bearing with the Spanner wrench until the retainer is reinserted
completely.
19. Pull up the rod and reinstall the upper clevis pin and setscrew.
20. Reconnect the cylinder hose.

and hydraulic components.
22. Restore the oil level (see oil recommendations in the “Routine Maintenance”

remove the maintenance block.
24. Lower the lift completely and hold the “DOWN” button for 60 seconds to allow air
in the cylinders to bleed back into the tank.
25. Raise the lift to 25 – 50% of its full travel, then lower fully holding the “DOWN”
button for an additional 60 seconds. Repeat this step 8 – 10 times.
