Autoquip PLD DOCK LIFT - Manual (Page 19)

19
Normally scissors lifts will require very little maintenance. However, a routine
maintenance program could prevent costly replacement of parts and/or downtime.
WARNING!
To avoid personal injury, NEVER go under the lift platform or perform any
maintenance on the lift until the load is removed and the scissors
mechanism is securely blocked in the open position. See "Lift Blocking
Instructions" section.
MONTHLY INSPECTION
1. Check oil level (see oil recommendations in this section) and add appropriate oil
when necessary.
2. Check for any visible leaks. Correct as necessary.
3. Check any unusual noise when it occurs. Determine the source and correct as
necessary.
4. Check the snap rings at all rollers, if not in place, and/or secure, replace or repair
immediately.
5. Check all rollers for signs of wear. Replace as necessary.
6. Do not grease roller or axles; they have lifetime-lubricated bearings.
7. Check all wiring for looseness or wear. Repair at once.
OIL REQUIREMENTS
Change oil yearly, or more frequently if it darkens materially or feels gummy or gritty.
Use detergent motor oils only. Do not use hydraulic-jack oil, hydraulic fluids, brake
fluids, or automatic transmission fluid.
