Before conducting any troubleshooting work, operators must first complete standardized safety pre-checks: fully lower the loaded forks to the flat ground, pull up the parking brake, cut off the main power supply, and hang a clear warning sign around the vehicle to inform passing staff not to approach the operation zone. Never carry out any troubleshooting procedures with forks suspended or loads kept at lifting height, and do not perform related operations on sloped ground to avoid accidental sliding of the equipment.

For the common no-start fault of electric forklifts, operators can carry out 3 basic inspection steps first without professional intervention. First, check the residual power of the battery pack to confirm whether the power level falls below the warning threshold that supports normal driving. Second, check the emergency stop button on the operation panel to confirm whether it is touched by mistake and stays in the locked position. Third, check the connection terminals of the battery to confirm whether there are loose connections or slight oxidation caused by long-term vibration. If all above items are confirmed to be normal and the fault still exists, operators should contact professional maintenance personnel in time instead of disassembling the battery compartment privately.

For abnormal walking control faults, operators can check if there are packaging fragments or small sundries stuck under the brake pedal that hinder its full rebound, confirm whether the forward and reverse gear lever is pushed to the correct position completely, and check whether the walking induction wire bundle at the bottom of the vehicle is scratched and displaced by scattered cargo debris on the passage. Do not step on the acceleration pedal repeatedly to try to force the vehicle to move, which may cause extra load on the control circuit and expand the fault range.

For abnormal lifting hydraulic faults, operators can check the oil level observation window to confirm whether the hydraulic oil stock stays within the specified range, check whether the dust cover of the lifting control lever is blocked by foreign matters, and check whether the fork body is hooked to the protruding structure of the surrounding shelf to cause motion locking. All basic troubleshooting operations must comply with the official operation specification, and operators shall not disassemble the core circuit or hydraulic components without permission to avoid unnecessary safety risks.
