3. Maintenance
3.1 Monthly
Inspection
All Anthony Tuckunder Liftgates are “Service-Free” which
means they have lubrication-free bushings at the major
pivot points.
Mechanical Components
1. Make sure the liftgate operates freely and smoothly
throughout its entire range of movement.
2. Check for damage to the liftgate, such as bent or
distorted parts. Check for excessively worn parts.
3. Check for cracked welds which may have resulted
from overload or abuse.
4. Check all pins and pivot points. Secure all pins with
proper retainers. Replace worn bushings and pins.
5. Oil the roller of the wheel arm and make sure it spins
freely.
6. Make sure platform is angled upward from truck
bed 1/2 to 3/4 inch when raised to bed height. See
Platform Adjustment for shimming procedure, “3.3
Mechanical Platform Adjustment” on page 8.
Power Unit
7. Check for oil leaks in the following areas:
a. Hydraulic lift cylinder.
b. Hydraulic hoses. Replace any hose that shows
signs of leakage or excessive abrasion of the
covering.
c. Check all hydraulic fittings for damage or leakage.
Tighten fittings to stop leaks or replace if damaged.
8. Check reservoir oil level and fill as required with
Dexron VI, Dexron III or Hyken Glacial Blu.
Electrical Components
9. Make sure all electrical wires, switches, and
connections are in good working condition and
operate properly.
10. Proper wire connection is crucial to the life and
dependability of the liftgate’s electrical components.
A poor connection can result in low Voltage, causing
the liftgate to work incorrectly.
11. Check the fluid level of the vehicle battery. Fill as
required.
Safety Signs and Informational Decals
12. Examine all warning, capacity, and operational
decals. If they are not readable, replace them.
Decals may be obtained free of charge your
authorized dealer.

ÀXVKWKHHQWLUHV\VWHP5H¿OOWKHV\VWHPZLWKWKH
recommended oil outlined in Step 8 of the “Monthly
Inspection” section.
3.3 Mechanical Platform Adjustment
The ramp (outboard) end of the platform should be 1/2 to
LQFKHVKLJKHUWKDQWKHWUXFNÀRRUZKHQLQWKHUDLVHG
position. If the outboard end of the platform is sagging,
add shims as described below. Shimming is a routine
procedure as the liftgate ages, and the parts become
worn.
1/2" to 3/4"
1. Lower the platform to the ground, it should touch at
the lift arm end and the ramp end (arrows).
2. To lower the ramp end:
a. Temporarily position a shim plate in the contact
area (arrows), between the cam plates and
platform, with tape.
