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 signs of wire rope damage is found.
Inspect entire lift for loose, damaged, or broken bolts. Replace as necessary.
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 a thin oil.
Check the power unit reservoir oil level. Add oil if necessary (use Dexron III ATF).
NOTE: Oil must be checked and filled 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.
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 difficult to displace and corrosion will begin immediately.
