Preventative Maintenence and Quick Check
The PTV needs preventive maintenance in order to achieve maximum performance. Lubricate and inspect
regularly. Also, check that there are no damaged components such as hoses, cables, controls, etc.
8.1
Quick Check List
1. Operate the liftgate throughout its entire cycle and check for noise and damage such as bent parts,
scratches, or cracked welds.
2. Inspect all welds and fasteners that attach the mount frame to the truck.
3. Check all pin retainer lock bolts for tight fit.
4. Visually inspect the hydraulic hoses for damage, scratches, bending or leakage. Also ensure that hoses
are not routed such that rubbing/wear on the hoses will occur- hoses should be securely fastened, not
loose.
5. Inspect the cylinders for leakage and make sure the cylinder pins are secured.
6. Check the oil level when platform is down. The level should be approx. 1.5
” below the top of the Oil Reser-
voir. PALFINGER Liftgates recommends replacing oil after the first 500 cycles, and then on a yearly basis
in the fall before winter begins.
7. Check for oil leakage around the power pack. Tighten or replace components if needed. If you perform
work on any hydraulic components, bleed the air out of the system by operating all functions several times
to self-bleed the lift cylinders. Run the gate all the way up and down to remove air from the fluid.
8. Check all electrical connections. Clean the battery terminals.
9. Inspect all terminals on the solenoid-operated valves at the port of the cylinder. Lubricate the terminals with
dielectric grease for better protection from corrosion, if needed.
10. Grease all zerks and link arms on the liftgate per the lubrication instructions and make sure that they all
accept grease. It helps to operate the liftgate while you do this.
11. Test all liftgates functions, if possible, with maximum loads placed according to load diagram.
12. Check the function of the pressure relief valve.
13. If you find any kind of damage that can make the operation of the liftgate dangerous, DO NOT CONTINUE
TO USE THE LIFTGATE. It must be completely repaired before using. All repairs must be made by an au-
thorized technician. Use only original spare parts. If in doubt contact your PALFINGER Liftgates distribu-
tor or PALFINGER Liftgates directly.
14. Perform the Trailer to Tractor Ground Test. Reference Section 8.3.
Do not ignore any liftgate damage; it can be dangerous for you and your co-workers.
