Forklift service frequency depends on the type of forklift, how intensively it is used, and its operating environment. As a general rule, internal combustion (IC) forklifts require service every 250–300 hours, while electric forklifts can typically go 500 hours between services.
Service Intervals by Usage Level
Usage Intensity Recommended Interval Typical Schedule
Light Use (1 shift, intermittent) Every 250–300 hours ~Every 6 months
Moderate Use (1-2 shifts, consistent) Every 200–250 hours ~Monthly to quarterly
Heavy Use (Multi-shift, max capacity) Every 100–200 hours ~Monthly or more frequently
Electric Forklifts Every 500 hours ~Every 3–6 months
For businesses using a forklift only 1–2 hours per day, servicing about twice a year is typically sufficient.
Service Schedule by Hours
A typical preventive maintenance schedule follows these hour-based milestones:
Every 250 Hours (~2 months):
Change engine fluids and filters (IC forklifts)
Lubricate chassis and mast components
Inspect hydraulic system and mast
Check belts, hoses, drivetrain, steering, and electrical system
Blow out and inspect brakes
Inspect tires for damage and wear
Inspect attachments (if applicable)
Every 500–600 Hours (~4 months):
All 250-hour service items
Replace spark plugs (IC forklifts)
Change differential and transmission oil
Inspect chains for damage and proper tension
Check mast operation and carriage rollers
Inspect hydraulic oil pump and filter
Clean radiator
Check/adjust chassis links and clutch release bearing
Every 1,000 Hours (~6 months):
All 250- and 500-hour service items
Change all fluids and filters (hydraulic, transmission, brake)
Replace spark plugs
Full tune-up
Every 2,000 Hours (~1 year):
All previous service items
Replace antifreeze, differential and transmission oil
Hydraulic pressure check
Cooling system check
Inspect steer axle and brake drums
Compression check
Clean and check fuel system
Electric vs. Internal Combustion (IC) Forklifts
Service Aspect Electric Forklifts IC Forklifts (Diesel/LPG)
Base Service Interval Every 500 hours Every 250–300 hours
Key Maintenance Areas Battery watering/cables, motor inspection, electrical diagnostics Engine oil, fuel filters, spark plugs, belts, exhaust
Why the Difference Fewer moving parts, less mechanical wear More moving parts, engine and fuel system wear
Additional Mandatory Inspections
Inspection Type Frequency Requirement
Daily Pre-Operation Inspection Every shift OSHA requirement (29 CFR 1910.178)
LOLER Inspection (UK) Every 12 months Legal requirement for lifting equipment
Safety Systems Check 6 months Lights, horns, brakes, seatbelts
Hydraulic Oil Filter Change Every 2 years Prevents lift system contamination
Factors That Require More Frequent Servicing
Extreme temperatures (heat or cold)
Dusty or dirty environments
Use of fork attachments (hydraulics work harder)
Heavy loads near maximum capacity
Seasonal spikes (service before peak season to avoid downtime)
Aging equipment (requires closer monitoring)
The bottom line: Forklifts should be serviced every 250–300 hours for internal combustion models and every 500 hours for electric models. Adjust intervals based on usage intensity—heavy use may require service as often as every 100–200 hours. Daily pre-shift inspections are legally required by OSHA, and comprehensive maintenance should follow manufacturer guidelines for your specific forklift model.
