7.1 Maintenance Checklist
DAILY
Check the truck on the following points before operation.
Remove load from truck and lower the forks to the lowest position.
DO NOT USE THE TRUCK IF ANY MALFUNCTION OR FAULT IS FOUND.
• Check for visible structural deformation or cracks of arms, forks, or any other component; and
unusual noise or binding of the lifting mechanism.
• Check if there is any oil leakage.
• Check the vertical creep of the lifting mechanism.

ANNUALLY
• Change the oil (more frequently if color has substantially darkened or feels gritty). The required
hydraulic fluid type is ISO VG32, its viscosity should be 30cSt at 40°C, total volume is about 33.8-44 fl
oz (1-1.3 L).
• Check all parts of the truck for wear and replace defective parts where necessary.
NOTE: If hydraulic oil is milky white in color, water is in the hydraulic system. Change the hydraulic oil
immediately.
7.2 Deaerating the Hydraulic System
Air may find its way into the pump during transportation, tilting or usage on uneven ground. It can result
in the forks no longer rising while pumping in the ‘Lift
’
position. The air can be removed in the following
way:
Move the control handle to the
Lower
position, move then the tiller down several times. Thereafter
normal operation can be resumed.
7.3 Check and Refill Hydraulic Oil
1) Ensure forks are in lowered position.
2) Lay pallet truck on side. Position drain plug of hydraulic cylinder up.
3) Remove the screw plug.
4) Add hydraulic oil until level of oil is at bottom of hole.
5) Replace drain plug, upright the truck
