Maintenance is to be performed by shop employee or trained lift service personnel.
Worn, damaged or broken parts need replaced with parts approved by the original equipment manufacturer or with parts
meeting original manufacturer specications.
MAINTENANCE
SCHEDULE
PERFORM THE FOLLOWING MAINTENANCE
Weekly Check the turning angle gauges and rear slip plates for smooth and easy operation. Clean by
blowing out with clean, dry compressed air. Disassembly is not required. DO NOT lubricate turning
angle plates or slip plates. (CAUTION: Always wear eye protection when using compressed air).
Check anchor bolts on each post for tightness. Torque to 100-110 ft-lb. Check and lubricate rear
ramp pivots with SAE 30 oil.
Monthly Check wire ropes for damage and lubricate with a thin oil (SAE 5W-30). Note: Do not use used
motor oils. They contain contaminants that will break down factory applied lubricants. Also,
do not use oils containing a solvent base (solvent cutback oils). They also will break down
factory applied lubricants. Replace wire ropes immediately if any sign of wire rope damage is
found. Inspect entire lift for loose, damaged, or broken bolts. Replace as necessary. Blow dirt from
insides of slide plates with compressed air (do not grease). Swing Air/Power Jacks: Clean swing
air jacks thoroughly with a degreasing solvent and dry. Wipe cylinder tubes with oil. Apply SAE 30
oil to rollers and pivot pins.
Check proper operation of control levers.
Check for air leak. Check that the locks are fully engaging and unlocking at the correct times.
Perform general structural check for damage.
Check columns and runways for corrosion. Corrosive agents, solvents, and road salts can greatly
reduce the life of the lift in a very short period of time. If these types of agents are spilled or
splashed onto the lift, immediately rinse area thoroughly with water. If they come in contact with
the wire ropes, wash the wire ropes immediately with water and re-lubricate with low viscosity oil.
Check the power unit reservoir oil level. Add oil if necessary (use Hunter’s specially ltered
DEXRON III transmission uid, 148-128-2). NOTE: Oil must be checked and lled when the lift is
in its fully lowered position. Remove air breather cap and oil full level screw located at the top of
the reservoir. Fill reservoir with oil until the oil begins to drip from full level screw hole. Replace air
breather cap and oil full level screw. If the oil level is found to be low, determine the source of the
oil loss and repair immediately.
Apply SAE 30 oil to all pivot pins, ramp pins, wheel stop pins and leg shafts. Wipe hoist cylinder
with oily cloth and lubricate gear rack.
Notes about corrosion: The best preventive maintenance against wire rope corrosion is to keep
the wire ropes well lubricated. The oil prevents moisture from entering into the wire rope strands.
Once salt and moisture have penetrated into the core of the wire rope it is very dicult to displace
and corrosion will begin immediately. Remove top slip plate. Clean thoroughly with a degreasing
solvent and dry. Coat unpainted surfaces,where balls roll, with paran. Replace any broken balls.
Replace top plate.
Every 6 Months Check runways and re−level as required.
Annually The entire lift should be inspected yearly (more frequently for severe use applications) by your
factory authorized service representative.
