i WARNING
Pressurized fluids can penetrate the skin.
Hydraulic hoses can fail from age, damage and exposure.
Do not search for hydraulic leaks without body and face
protection. A tiny, almost invisible leak can penetrate the skin, requiring
immediate medical attention.
Use wood or cardboard to detect hydraulic leaks, never your hands.
i WARNING
Spilled hydraulic fluid is slippery and may also present a fire
hazard.
Clean up spilled hydraulic fluid.
Normally, scissor lifts will require very little maintenance. However, a routine maintenance program
could prevent costly replacement of parts and/or downtime.
6.2.1 Every Day or 10 Hours Of Operation
•
Check reservoir fluid level.
•
Check for fluid leaks.
•
Check all hoses and electrical cords for cracks, abrasions, twisting, etc. Small leaks at
connections can be remedied by tightening connections or replacing faulty component.
•
Check that oil 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.).
6.2.2 Every Month or 100 Hours Of Operation
•
Check quality of oil. Replace if discolored (oxidized), cloudy, or otherwise contaminated. Do not
overfill reservoir. 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 rollers & pivot points for proper retention & tightness.
•
Inspect cylinder base pin keeper bolts. Tighten if needed.
•
Inspect all cylinder rod roll pins for proper seating & retention.
When all 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.
