Basic Guide To Diesel Forklift Truck Maintenance

Diesel forklift trucks are a popular choice for many businesses due to their power and durability. However, like any other machinery, they require regular maintenance to ensure they operate at peak performance and last longer. In this guide, we’ll go over the basics of diesel forklift truck maintenance to help you keep your equipment in top condition.

Regular Inspections

Regular inspections are crucial to identify any potential issues before they become major problems. Inspect the forklift before each use and conduct a more thorough inspection weekly or monthly. Check the tyres, brakes, steering, and hydraulic systems, as well as the engine, transmission, and exhaust system. Look for signs of wear and tear, leaks, loose bolts, and damaged parts. Replace any worn or damaged parts immediately. Booking your forklift in for the required amount of services throughout the year is also advised.

Oil and Filter Changes

Regular oil and filter changes are essential for the proper functioning of the engine. Check the manufacturer’s recommendations for the frequency of oil and filter changes, as they may vary based on the forklift’s usage and operating conditions. Use the recommended type and grade of oil and filter and dispose of the old oil and filter properly.

Fuel System Maintenance

The fuel system is another critical component of a diesel forklift truck. Check the fuel tank, lines, and filters for any signs of damage or leaks. Replace any damaged or clogged filters and keep the tank clean to avoid contamination. Proper fuel system maintenance can prevent costly repairs and improve fuel efficiency.

Battery Maintenance

If your diesel forklift truck has a battery, proper maintenance is crucial to extend its life and avoid downtime. Check the battery and cables for any signs of corrosion or damage and clean them regularly. Make sure the battery is fully charged before each use and avoid overcharging or undercharging it. If the battery is damaged or no longer holds a charge, replace it immediately.

Cleaning and Lubrication

Regular cleaning and lubrication can prevent rust, corrosion, and wear and tear. Wash the forklift regularly with a pressure washer or a hose and a mild detergent and dry it thoroughly to avoid water damage. Lubricate the moving parts, such as the chains, forks, and mast, with the recommended grease or oil to reduce friction and prolong their lifespan.

Safety Precautions

Diesel forklift trucks can be dangerous if not operated and maintained properly. Make sure all employees who operate the forklift are trained and certified and follow all safety regulations and guidelines. Use personal protective equipment, such as gloves, eye protection, and steel-toed shoes. Keep the forklift clean and free of clutter and avoid overloading or exceeding the maximum load capacity.


Regular maintenance is essential to keep your diesel forklift truck operating at peak performance and avoid costly repairs and downtime. Follow these basic maintenance tips to extend the lifespan of your equipment, improve fuel efficiency, and ensure workplace safety. If you’re unsure about any aspect of maintenance, consult with a forklift expert or a manufacturer’s representative. With proper maintenance, your diesel forklift truck can serve your business for many years to come.
