Keep Your Forklift Running Smoothly: A Preventive Maintenance Guide

Written by Staff Writer

Imagine the constant movement of forklifts in a busy warehouse or a bustling construction site. These machines lift and carry massive loads, saving time and effort on the job.

But if something goes wrong — like a brake failure or a broken mast — the results can be expensive, dangerous or even tragic. That's where preventative maintenance comes into play, ensuring your forklifts perform reliably and operators stay safe.

Below, you'll find a detailed checklist for forklift maintenance, along with insights on why OSHA-compliant training and certification are crucial. You'll also see how you can combine preventative care with operator education to reduce mechanical failures, prevent accidents and satisfy regulatory requirements.

Why Preventative Maintenance Is Critical

Forklifts are integral to a range of industries, from warehousing and logistics to construction. A breakdown can cost thousands of dollars in repairs and lost productivity. Worse yet, it can pose a serious safety risk: malfunctioning brakes or faulty steering may cause collisions, injuring workers or damaging valuable inventory.

OSHA compliance underlines the importance of frequent inspections and addressing worn or failing parts. When your workforce understands how to perform daily checks and follow safe operating procedures, you substantially lower the possibility of hazards, injuries and citations.

Key Forklift Components

Although different types of forklifts exist — powered by combustion engines, electricity or propane — most models share these core components:

• Engine / Power Source: The heart of the forklift, which may be gasoline, diesel, electric or propane-powered.
• Counterweight: Balances the load so the forklift doesn't tip over.
• Carriage: The base for the forks and mast, supporting heavy loads.
• Mast: Houses the chains, forks and rails that enable lifting.

Understanding these components helps identify what to inspect for wear and tear, ensuring the forklift stays safe and operational.

Maintenance Checks Before Turning the Key

A significant part of forklift upkeep occurs while the forklift is shut down. This is your opportunity to pop the hood, check fluid levels and verify that vital components are in good shape. Although specific steps vary by power source — internal combustion engines, electric batteries or liquid propane — the core principle is the same: stop small issues from escalating into major failures.

Internal Combustion Engine Forklifts

These forklifts often rely on gasoline or diesel fuel and are common in outdoor or high-capacity settings.

• Oil Levels: Make sure the engine oil is topped off to the recommended mark. Low oil can lead to friction damage and engine seizure.
• Coolant and Brake Fluids: Keep a close eye on coolant levels to avoid overheating. Check brake fluid to ensure the brakes engage properly.
• Radiator and Air Filters: Clean the radiator to remove debris and replace the air filter periodically (often after every 500 hours).
• Hoses and Belts: Look for cracks, wear or looseness. Damaged belts can cause severe engine problems if not replaced in time.

Battery-Powered (Electric) Forklifts

Electric forklifts are popular for indoor use due to their quieter operation and zero emissions.

• Water Levels: If your lead-acid battery is low on water, it can affect the battery's performance and shorten its life.
• Sulfur Deposits: Lead-acid batteries can develop crystal-like deposits that reduce efficiency or even cause shorts. Check and clean regularly.
• Wiring: Make sure cables are secure and free from frays or cracks. Exposed wires are a significant safety hazard.

Liquid Propane Forklifts

Liquid propane is a highly flammable fuel, so extra care is necessary.

• Propane Tank: Confirm it's properly mounted. Any hissing sound may indicate a leak.
• Relief Valve: Ensure the valve is positioned upright for safe pressure release.
• Belts and Hoses: Just like with combustion engines, check for damage.

Maintenance Checks When the Forklift Is Running

After the "under-the-hood" examination, the next step is to turn the forklift on and see how it performs under basic operating conditions. These running checks involve evaluating tires, steering and safety devices to make certain everything works seamlessly.

Tires, Steering and Brakes

• Tire Condition: Inspect for wear, punctures or insufficient tread. Flat or damaged tires can compromise forklift stability and lead to rollovers.
• Brake Function: Test the brakes at low speed to ensure they respond promptly and stop the forklift smoothly.
• Steering Responsiveness: A forklift that veers or resists turning can create dangerous handling situations.

Accelerator, Clutch and Gears

• Acceleration: If the forklift lags when you press the pedal or lurches unpredictably, schedule a repair.
• Shifting / Clutch: Certain forklifts allow gear shifts for faster movement. Verify that each gear change is smooth and free of grinding noises.

Lights and Alarms

• Headlights / Brake Lights: Proper lighting is critical in darker areas or busy environments.
• Audible Alarms: Horns and backup alarms warn nearby workers of the forklift's movements, preventing accidents.

Safety Devices and the Forklift Mechanism

• Seatbelt: OSHA requires seatbelts on most forklifts to protect operators in a tip-over event.
• Carriage and Mast: Check for loose bolts, ensure the mast moves fluidly and lubricate moving parts regularly. Any unusual grinding or squeaking is a red flag.

Build a Regular Maintenance Schedule

Even the most thorough daily inspections won't be enough if you don't have a broader, systematic plan. Here are some steps to set up a proper maintenance regimen:

1. Follow Manufacturer Recommendations
   Each forklift model comes with specific guidelines for maintenance tasks and intervals. Adhering to these recommendations extends the life of your machine and preserves its warranty.
2. Schedule Inspections
   1. Frequent Basic Inspections: These can occur daily or every 200 hours of operation, depending on usage.
   2. Comprehensive Annual Inspection: Once a year, or approximately every 2,000 hours, conduct in-depth reviews of all forklift components.
   3. Pre-Use Checklist: Operators should use a standardized checklist before each shift to catch any obvious issues.
3. Use a CMMS (Computerized Maintenance Management System)
   If you have a large fleet or handle multiple operations, a CMMS automates tracking, scheduling and reporting. This system helps technicians and operators stay organized, ensures that inspections aren't missed, and logs completed maintenance tasks.
4. Encourage Operator Feedback
   Operators know the machines best. Implement a clear reporting process that allows them to flag issues early.

Strengthen Maintenance With Proper Training

Maintaining a forklift is only half the battle. Ensuring operators use it correctly is equally vital to safety and longevity. Consider how an online, OSHA-compliant course not only meets federal requirements but also teaches best practices that lower the risk of avoidable damage.

• Formal Instruction: Take our forklift certification course to fulfill the education portion of OSHA requirements.
• Hands-On Demonstrations: Learn to identify and handle jobsite-specific hazards.
• Evaluation: Once you pass the employer-led performance test, you'll have a valid forklift certification card — accepted nationwide.

Refresher training is recommended every three years or whenever an operator has been observed operating a forklift unsafely, is involved in an accident or works with new types of equipment.
