ROUTINE MAINTENANCE
WARNING !
Before maintaining the lift, read & follow the recommended
safety practices in the Safety Practices section. Failure to follow
these safety practices could result in death or serious injury.
Normally scissors lifts will require very little maintenance. However, a routine
maintenance program could prevent costly replacement of parts and/or downtime.
DANGER!
Do not work under the lift without a Maintenance Device! To
avoid personal injury, NEVER go under the lift platform until the
load is removed and the scissors mechanism is securely
blocked in the open position and the appropriate OSHA lock-
out/tag-out procedure is followed . See "Lift Blocking
Instructions" section.
Daily Inspection List (10 hours of operation):
• Check hydraulic reservoir fluid level. Hydraulic pump unit is supplied by others.
• Check for hydraulic fluid leaks.
• Check all hydraulic hoses and electrical cords for cracks, abrasions, twisting, etc.
Small leaks at connections can be remedied by tightening connections or replacing
the faulty component.
• Check that hydraulic pressure does not exceed 2,000 psi.
• Check all pivot joints & roller bearings for noise and wear.
• Check overall condition of unit (i.e. bends, breaks, loose or missing screws, etc.).
Monthly Inspection (100 hours of operation):
• Check quality of hydraulic fluid. Replace if it becomes discolored (oxidized),
cloudy, or otherwise contaminated. Factory recommended fluid is SAE 10W-30 oil.
DO NOT OVERFILL. Always use clean fluid.
• Inspect lift cylinder rods for scoring and leaking, wipe away any foreign material.
• Inspect all structural and mechanical components for cracked, or broken welds and
any distortion caused by collision, overloading, or other misuse.
• Inspect snap rings/bolts at all rollers & pivot points for proper retention & tightness.
• Inspect retainer bolts which capture cylinder trunnion pins for proper retention.
When all above checks have been completed start unit and operate through all
functions. Inspect all components for signs of noise, vibration, erratic movement, and
any other abnormal behavior.
