Maintenance
1. Before each use, check for any Hitch Lift damage, loose hardware, crimped cable,
bent components. If any are found, do not use until properly repaired by a qualified
technician.
2. Periodically clean all components with a mild soap and water.
3. Periodically lubricate moving joints with a light oil.
Replacing the Lift Cable
1. Using a Phillips screwdriver, remove the screws holding the Limit Switch Cover Plate
to the Motorized Cable Module (27). Remove the Cover Plate.
2. Using the Pistol Grip Trigger, lower the Deck Plate to the ground.
3. Loosen the Adjuster Locking Nut. While pulling on the cable, move the Lower Limit
Cam (white) so that all the cable can be unwound.
4. Using an Allen Wrench, remove the two set screws (S) located on the cable drum
(above the cable holes). Pull the cable end out of the hole. See photo K.
5. Remove the other end of the cable from the Lifting Arm (33).
6. Unwind the new cable (22) and push the end through the
holes in the cable drum. See Assembly Drawing, Item # 3.
The cable end should not protrude out of the second hole,
but just meet the cable drum surface. Screw in the two new
set screws that came with the new cable. Securely tighten.
7. Using the Pistol Grip Trigger, rewind the new cable onto the
cable drum so that each turn is side-by-side.
Keep tension on the cable while rewinding. Leave enough
cable out to connect the other end to the Lifting Arm (33).
It may be necessary to adjust the Upper Limit Cam (black)
while rewinding.
8. Adjust the Upper and Lower Limit Cams as described on page 8.
9. Replace the Limit Switch Cover Plate and Screws.
