Scissor Lift Inspection and Maintenance
Draper recommends inspecting the Scissor Lift at least annually or every 300 cycles—whichever comes first.
A recommended maintenance schedule includes:
• Cables: Check for fraying.
• Drive Chain Gears: Check for
rust, breaks, secure attachment.
• Fasteners along scissor arm assemblies: Make sure they are not loose.
If any are loose, hand tighten the nuts.
Please Note: There is no need to tighten nut in the top scissor which
slides back and forth in the side slot in the lift. Tightening this fasteners
assembly will cause the unit to lock up and lead to damage to the unit.
• Closure: Ensure threaded rod remains
seated firmly in the closure panel
corners, and that nuts remain tight. If
they are loose, tighten them.
