How to properly maintain an electric forklift?

Proper maintenance of electric forklifts helps ensure stable operation, extend battery life, reduce repair costs, and minimize safety risks. Below is a detailed guide to the electric forklift maintenance process:

🔹 1. Daily Maintenance

• Check the battery:

  • Ensure charge level ≥ 20% before operation.

  • Avoid frequent partial charging; fully charge before use.

  • Check coolant level (for lead-acid batteries) and add distilled water if necessary.

• Check the wheels: wear, cracks, and pressure (if pneumatic).

• Brakes & horn: ensure proper function.

• Lighting system, mirrors, cameras (if equipped): work normally.

• Clean the truck: wipe off dust, dirt, and grease.

🔹 2. Weekly Maintenance

• Check hydraulic oil level and refill if necessary.

• Lubricate and check the tension of lift chains.

• Inspect forks for deformation or cracks.

• Clean air filters and radiator to prevent overheating.

🔹 3. Monthly Maintenance

• Inspect the entire electrical system: wiring, fuses, connectors, switches.

• Check the electric motor for overheating or unusual noises.

• Tighten bolts and nuts: wheels, axles, and frame.

• Lubricate joints and bearings.

🔹 4. Periodic Maintenance (Every 3–6 months)

• Replace hydraulic oil (according to manufacturer’s recommendation).

• Test the battery with specialized equipment: voltage and remaining capacity.

• Adjust steering and braking system.

• Inspect sensors and ECU (for modern electric forklifts).

• Perform professional maintenance at service centers for comprehensive safety checks.

🔹 5. Important Notes for Use & Maintenance

• Do not let the battery discharge below 20% before charging → prevents battery damage.

• Do not wash the forklift directly with high-pressure water into the electrical compartment, battery, or motor.

• Park in a dry, ventilated place, away from direct sunlight.

• Follow the manufacturer’s maintenance manual.
