Factory answers on LED display codes, battery charging and safety valve settings for this electric pallet truck sit in one place: the 45-page Utilev UT20RE operator manual PDF, OEM ID 66306325. A hydraulic principle diagram traces oil from pump to lifting cylinder and back through the safety valve, while the electrical troubleshooting section pairs wiring with encoder and voltage checks so you can trace a no-start to the right circuit. Battery chapters cover initial, equalizing and end-of-life charging, and the maintenance schedule runs from daily inspection through 50, 200 and 1200 hour services, with fault charts for lifting noise, steering and brakes. Match any replacement charger to the 24V, 30A output, and retire a drive wheel once its diameter has shrunk by 5%. Bookmarks and a live text layer put your chapter one click or one search away.

Utilev UT20RE Common Problems This Manual Covers
Utilev UT20RE brake gives no noise when operation handle switches between area A and B
Check the brake by swinging the operation handle between area A and B and listening for the brake noise. Measure brake clearance against 0.2mm to 0.8mm as listed on page 13. If it is out of range, contact the sales department. Never use the faulty truck (page 14). Lower the fork arms fully, put on the warning board and pull the key (page 13).
Manual Section: Inspection before operation p. 13Wheel diameter visibly worn and wheel pins or screws loose during pre-operation inspection
Check every wheel fastener, including pins and screws, for looseness as part of the pre-operation inspection on page 13. Measure wheel diameter and compare it against the parameter list. Replace the wheel when diameter reduces by 5%, per page 14. Do not run the truck on a worn or loose wheel: never use the faulty truck (page 14).
Manual Section: Inspection before operation p. 14Oil leaking from oil pipe or lifting oil cylinder and hydraulic oil level low
Inspect the oil pipe and lifting oil cylinder for leakage and verify appropriate hydraulic oil quantity during the pre-operation check on page 13. Hydraulic oil charge is 1.5L, listed on page 22. If you find a leak, contact the sales department and park the truck out of traffic. Never use the faulty truck (page 14).
Manual Section: Inspection before operation p. 13Truck will not start with electric lock ON and instrument not displaying normally
Check the start sequence on page 14: open the guardrail, turn the electric lock ON, move the operation handle to area B and rotate the accelerator knob slowly. Confirm the battery capacity display and that the battery connecting line and socket are firm. Keep tools and metal off the lidless battery (page 35). Then work through the start failure entry on page 27.
Manual Section: Common Faults and Troubleshooting p. 27Battery voltage dropping to 20.4V and electrolyte density falling to 1.17 during shift
Stop discharging and charge at once when total voltage reaches 20.4V or electrolyte density reaches 1.17, per page 18. Run a common charge at 20A first stage and 10A second stage, about 12 hours. A full automatic charger must deliver 24V and 30A (page 20). Charge with no open flame present at the charge place (page 15).
Manual Section: Usage, Maintenance and Charge of Storage Battery p. 18Storage battery electrolyte solution getting hot and temperature approaching 45℃ during charging
Measure electrolyte temperature while charging. It must not exceed 45℃. When it gets close, reduce charging current by 50% or stop charging temporarily, then wait until it drops to 35℃ before continuing, per page 18. Prolong the charging time to compensate. Keep the charge place free of open flame (page 15).
Manual Section: Usage, Maintenance and Charge of Storage Battery p. 18Frequently Asked Questions
What do UT20RE warning lights and fault codes mean?
Fault codes are displayed on the 1311 display. For example, code 1,2 indicates a motor speed encoder issue where the speed sensor signal cannot be detected, potentially due to incorrect wiring or a defective controller. Code 3,2 indicates a main contactor issue, such as a coil being open or the contactor being stuck closed. p. 30
How do you troubleshoot a UT20RE that will not lift or travel?
If the truck cannot start, check if the storage battery is used up, the wire terminal is loosened, the fuse is burnt out, or the accelerator is damaged. If there is abnormal noise during lifting, check if the oil-absorptive filter is blocked or if the oil-absorptive tube leaks and the oil is foaming. p. 27
What are the replacement specifications for the drive wheel on the Utilev UT20RE?
The drive wheel should be replaced when its diameter reduces by 5% compared to the original parameter list. p. 14
What are the replacement specifications for load wheels and wheel bearings on the Utilev UT20RE?
The bearings of the fork wheel and the fork wheels themselves have a maintenance replacement period of 1200 hours. p. 26
What is the required hydraulic oil level and capacity for the Utilev UT20RE?
The distance between the oil level and the bottom of the oil tank should be about 70mm, and the total oil charge is 1.5L. p. 22
