Toyota 8FD25 Diesel Forklift – Monthly Maintenance Checklist

Perform monthly maintenance on Toyota 8FD25 diesel forklifts to ensure long-term durability and safety compliance.

Tyres and Wheels

  • Check tyre pressure (solid/pneumatic) for appropriateness and evenness.
  • Inspect tyre surface for cracks, splits, or embedded debris.
  • Verify adequate tread depth (visual check or gauge).
  • Inspect rims for damage, warping, or weld cracks.
  • Inspect wheel bearings for wear and ensure proper lubrication.

Fluid Checks

  • Verify engine oil level and condition.
  • Inspect hydraulic fluid level and clarity.
  • Check transmission fluid (if separate).
  • Check brake fluid level and ensure no signs of contamination.
  • Check radiator coolant level and ensure there are no leaks.
  • Confirm fuel level (diesel tank) and ensure the cap is tight.
  • Look for any visible fluid leaks under the forklift.
  • Check for any condensation in the fuel system or water separator.

Forks & Mast Assembly

  • Inspect forks for straightness, ensuring they are not bent and are securely mounted.
  • Verify fork heel wear is within acceptable limits (below 10% of original thickness).
  • Inspect locking pins and retaining clips for wear and security.
  • Check mast chains for lubrication and even tension.
  • Inspect lift cylinder pins and bushings for security and wear.
  • Inspect the backrest and carriage assembly for cracks and security.
  • Lubricate all moving parts of the mast assembly, including guide rollers and tilt mechanism.

Brakes & Safety Systems

  • Test both the service and parking brakes for effectiveness and functionality.
  • Check brake pads for wear and ensure they meet the required thickness.
  • Inspect emergency stop / kill switch functionality.
  • Inspect fire extinguisher for full charge and expiry.
  • Ensure overhead guard and operator compartment are secure.
  • Verify load capacity plate is still readable and accurate.
  • Test horn, backup alarm, and lights for functionality.
  • Inspect the seat belt for wear and ensure proper operation.

Hydraulics and Operational Functions

  • Check hydraulic hoses for any signs of leaks, damage, or chafing.
  • Inspect hydraulic fluid lines for proper attachment and routing.
  • Verify smooth operation of lift, tilt, and side-shift functions.
  • Ensure engine starts without abnormal noise or smoke.
  • Verify that the engine operates at the correct temperature.
  • Check the condition and operation of the steering mechanism.

Engine and Exhaust System

  • Inspect exhaust system for leaks, damage, or unusual noise.
  • Check engine air filter and replace if needed.
  • Inspect all cooling system components (radiator, hoses) for leaks or damage.
  • Clean or replace the air intake system filters if necessary.
  • Inspect the engine for excessive wear, leaks, or unusual vibrations.

Battery and Electrical Systems

  • Inspect battery terminals for corrosion and ensure they are tight.
  • Check battery charge levels and recharge as necessary.
  • Inspect all wiring for damage, wear, or exposure.
  • Test lights, indicators, and other electrical components for proper operation.
  • Ensure all battery compartment covers are in place and secure.

General Inspection

  • Inspect the general condition of the forklift body for any visible damage or wear.
  • Check for any loose bolts, fasteners, or components that need tightening.
  • Clean the forklift thoroughly, including removing debris from under the body and around the engine.
  • Perform an overall inspection for any abnormal wear or damage to critical parts.
