Complete Forklift Maintenance Checklist: What Gets Checked and Why

A full breakdown of what a proper forklift service covers — use this as a benchmark for any service quote you receive.

Many operators have no idea what their forklift service actually includes — and some service providers take advantage of that. This checklist covers what a proper 250-hour, 500-hour and 1000-hour service should include, so you can hold any provider accountable.

Pre-Service Visual Inspection (Every Service)

Fluid levels

Engine oil, hydraulic fluid, coolant, brake fluid — check and top up

Tyre condition and pressure

Solid tyres for chunking or flat spots; pneumatic for correct pressure

Fork and mast visual check

Cracks, bends, wear on heel plates and tine tips

Chain inspection

Lubrication, elongation, cracking or corrosion

Fluid leaks

Check under the machine and around cylinder seals

Overhead guard condition

No cracks, bends or missing bolts

Engine Service Items

Engine oil and filter change

Every 250 hours on most diesel engines; 500 hours on newer LPG

Air filter inspection and replacement

Blocked air filters cause fuel consumption spikes

Fuel filter replacement

Diesel: every 500 hours. LPG: inspect regulator and vaporiser

Spark plug inspection (LPG)

Replace every 1000 hours or if misfiring

Cooling system flush

Every 2000 hours or 2 years

Drive belt inspection

Alternator, fan and power steering belts for cracking or slipping

Hydraulic System

Hydraulic fluid level and condition

Dark or milky fluid means contamination — change immediately

Hydraulic filter replacement

Every 1000 hours or annually

Cylinder seal inspection

Check for weeping seals on lift and tilt cylinders

Mast chain lubrication

Must be properly lubricated at every service

Hose condition check

Cracking, swelling or rubbing on any hydraulic hose

Lift and tilt function test

Smooth operation under load at rated capacity

Brake and Drivetrain

Brake adjustment and inspection

Drum brakes: adjust shoes. Disc: check pad thickness

Brake fluid change

Every 2 years or when contaminated

Transmission fluid level

Check and top up; full change every 2000 hours

Drive axle oil level

Often overlooked — starvation causes bearing failure

Parking brake test

Must hold the loaded machine on the rated slope

Electrical and Safety Systems

Battery voltage and electrolyte check

Wet-cell batteries: top up distilled water, check specific gravity

Alternator output test

Should produce 13.8–14.4V at operating RPM

Warning light and horn function test
Seatbelt condition and latch function
Seat switch operation

Machine should not move without operator in seat

Lights (where fitted)
