SERVICE

IF LIFT DOES NOT RISE TO FULL HEIGHT -- check for leaks or shortage of oil. Maintain the proper oil level.

IF THE LIFT TENDS TO CREEP DOWNWARD UNDER A LOAD -- a speck of dirt may be obstructing the seating of the valve and allowing leakage. To correct, follow these instructions:

•Raise lift to full lifting height and then lower it to lowest point of lift. It may be necessary to do this five or six times. In lowering the lift, lower it in stages, that is, lower the lift six inches to a foot at a time. This will dislodge the dirt and lift will operate properly.
