Autoquip VERTICAL RAM LIFTS - DUAL RAM - Manual (Page 28)

28
Normally platform ram lifts 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 platform is
securely blocked in the open position. See "Blocking Instructions"
section.
MONTHLY INSPECTION:
1. Check oil level (see “Oil Requirements” in this section) and add appropriate oil when
necessary.
a. Rams already in service need prefilling to the proper checkpoint before bleeding,
only when they are suspected of having less than two-thirds of their normal oil
supply.
b. To bleed the trapped air from rams already in service: Raise the empty lift half
way and loosen the bleeder plug four turns. When the oil comes out air-free,
tighten the bleeder plug.
c. All rams should be lowered fully to check the oil. However, when there is no
superstructure on the ram, it should not be lowered below the cylinder flange,
except for seal-ring replacement and/or cleaning the seal-ring groove.
d. Remove the fill plug of the reservoir and fill it to within two inches from the top.
e. Replace the fill plug.
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 all wiring for looseness or wear. Repair at once.
5. Keep all bolts tight.
6. Keep the superstructure and surrounding area free of oil, grease, and dirt.
