Autoquip DOUBLE PANTOGRAPH LIFT - Manual (Page 36)

Daily Inspection List (10 hours of operation):
• Check reservoir fluid level.
• 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 3,000 psi.
• Check overall condition of unit (i.e. bends, breaks, loose or missing screws, etc.).
Monthly Inspection (100 hours of operation):
Normally scissors lifts will require very little maintenance. However, a routine maintenance
program could prevent costly replacement of parts and/or downtime.
• Check quality of oil in reservoir. Replace if it becomes discolored (oxidized), cloudy, or
otherwise contaminated. Factory recommended fluid is SAE 5W30 motor oil. DO NOT
OVERFILL. Always use clean oil.
• 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.
• Check all rollers for signs of wear. Replace as necessary. Do not grease roller or
axles; they have lifetime-lubricated bearings.
• Check all wiring for loose connections or wear. Repair at once.
• Check for damage on all hinged, throw-over bridges. Any lift which has a damaged
bridge, to the point of hanging more than 30 degrees below horizontal is in violation of
safety standards as set forth in ANSI MH29.1 and MUST be taken out of service until
the bridge is repaired or replaced.
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.
Annual Inspection (1000 hours of operation):
• Drain oil in reservoir and clean reservoir as needed. Always fill reservoir with New
SAE 5W30 motor oil. Never fill reservoir with used oil or excess oil from a drip pan or
pit. Dispose of and handle the used or excess oil as a hazardous material.
• If noise or vibration has been noticed, remove lift cylinder pins, pivot pins, and roller
bearings. Inspect for wear and replace as necessary.
• Replace any hydraulic hose that shows signs of chafing or leaking.
• Replace suction filter.
• Check for permanent mechanical deformation.
