Inspecting and Adjusting the Lift Column

NOTE: For this procedure, refer to FIGURE 3.3.

NOTE: The six nylon bearings installed in the outer column have been adjusted at the factory before shipping. They keep the outer column centered around the inner column and provide a smooth glide up and down. The ends of the bearings can wear with use and should be checked periodically. Approximately every six months, check the adjustment of the bearings (Detail “C”).

1.Remove the outer shroud by removing the two front and four rear mounting screws, and the self tapping screws holding the two halves of the shroud together (Detail “A”).

2.Raise the lift until about 18” of the inner column are exposed.

3.Rub a light coat of machine oil up and down the inner column until a film of oil is clinging to all four surfaces.

4.Raise and lower the lift.

5.Check the four surfaces of the inner column to see if there is a noticeable track in the oil film from the nylon bearings (Detail “B”).

NOTE: If the bearings are making sufficient contact with the inner column, you will see four tracks in the oil.

6.If there is not a track in the oil film in one or more of the sides of the inner column, that sidesbearingsneedtobeadjustedINtowardthecolumnbyperformingthefollowing:

A.Using a very large bladed screwdriver or a quarter held firmly with a pair of pliers, turn the bearing IN just an 1/8th of a turn (Detail “C”).

B.Run the lift up and down again and see if the bearing is now contacting the inner column enough to make a track in the oil. If not repeat STEP “A”.

NOTE: When both the left and right sides and the front and back sides of the inner column show a slight track in the oil film, your bearings are properly adjusted.

NOTE: It is very important that you DO NOT run the bearings in so far as to make the lift bind going up and down.

7. Wipe the excess oil film and replace the shroud.
