SECTION 6. (CONTINUED) MAINTENANCE INSTRUCTIONS
8. Never work on the pneumatic systems unless the unit is fully lowered or properly
sitting on the safety support or wheel block.
9. Never apply a load to the equipment until the baseframe is continuously supported.
10. WARNING! Never expect to hold the leg assemblies open by simply lifting one end
of a platform.
A. The roller end of most lifts is not “gibbed” or captured in any way, so lifting on the
roller end will simply tilt the platform.
B. Even if you raise the clevis end of the platform, if the base frame is not firmly
lagged to the ground or held down by some other means, the legs will come up
with the platform in an unpredictable manner and could cause personal injury.
C. The only safe way to hold a lift’s legs open other than the factory designed safety
support, is to block between the clevis end of the platform and the baseframe.
Routine Maintenance: (All lifts)
Weekly: Once a week or after repetitive operation, the unit shall be raise to its full
height. The air spring and supply hose shall be examined for signs of wear.
Monthly:
WARNING! Be sure a maintenance safety leg or safety bars are properly engaged
before performing maintenance checks 2 through 6 or reaching beneath a raised lift.
(See instructions 3, 4 and 10 above).
1. Clean all debris from the vicinity of floor and pit mounted units in order to avoid
interference with the lift mechanism or rollers.
2. Check for presence and proper seating of all snap rings and clips on all axles and
rollers.
3. Check rollers, pins and bushings for any signs of wear such as flat spots, missing
fasteners, or dislodged bearing material.
4. Check the pneumatic fittings for cracks or leaks.
5. Check hoses for abrasions or other abuse and check for snug connections.
6. Operate the unit and check for any abnormal noise or vibrations.
7. Check all safety devices on the unit such as the condition of the pleated bellows or
smooth operation of a limit switch.
