A forklift that quits mid-shift costs far more than the repair invoice. Add an idled crew, rush freight on parts, and a rental to cover the gap. A single breakdown can run into thousands. A planned maintenance program stops most of that before it starts by putting inspections and service on a set schedule.
What a Planned Maintenance Program Covers
Also called a PM program, it is a documented system for inspecting, servicing, and repairing equipment on a schedule instead of after a failure. Work is triggered in advance by hours of operation, calendar dates, or measured condition, and every visit is recorded.
What Triggers the Service
- Hour meter readings, the most accurate measure of real wear
- Calendar dates, useful for low-hour trucks that still age
- Condition data gathered during inspection and monitoring
Why Hours Beat the Calendar
A truck running two shifts accumulates four times as many hours as one running four hours a day. Putting both on the same quarterly cycle over-services one and neglects the other. Hour-based intervals fix that.
Key Takeaway: If your schedule is built on months rather than hours, your hardest-working trucks are almost certainly overdue right now.
Planned, Preventive, Reactive, and Condition-Based Maintenance
These terms get used interchangeably, and the difference matters when you compare service agreements.
Reactive Maintenance
Work happens after something breaks. It is the most expensive approach per incident because you pay premium rates for parts, labor, and downtime at the same time.
Preventive Maintenance
Service happens at set intervals. Oil and filter changes, lubrication, battery service, and routine inspection all fall here.
Planned Corrective Maintenance
Repairs flagged during an inspection get scheduled for a convenient window, such as a Saturday shutdown, instead of interrupting production.
Condition-Based Maintenance
Measurement triggers the work. Hydraulic oil sampling, chain elongation checks, and telematics fault codes are common examples.
Planned maintenance is the umbrella covering the last three. Reactive work is what a good program is built to eliminate.
What We Check During a PM Visit
Power System and Drivetrain
- Engine oil, filters, coolant, and belts on internal combustion (IC) trucks
- LPG regulator, hoses, and fittings
- Lead-acid batteries: water levels, specific gravity, terminals, and cables
- Lithium batteries: fault history, connectors, and charger compatibility
Mast, Forks, and Hydraulics
- Lift chains gauged for elongation and correct tension
- Forks measured at the heel, where wear concentrates
- Hoses, cylinders, fittings, fluid level and condition
Brakes, Tires, and Safety Systems
- Service and parking brake performance
- Tire wear and mounting
- Horn, lights, seat belt, overhead guard, legible data plate
ANSI/ITSDF B56.1 calls for a fork to be pulled from service once blade thickness drops to 90 percent of original. At that point the fork has lost roughly 20 percent of its rated capacity, which quietly turns a 5,000 lb truck into a 4,000 lb truck. The same standard calls for fork inspection at least annually in single-shift operations, and more often under heavy use.
Pro Tip: Federal OSHA does not require written records of daily forklift examinations. It does require the examination itself, and it holds you responsible for showing that trucks are properly inspected. Service reports are the cleanest way to do that, and they pay off again at trade-in.
How Often Should Forklifts Be Serviced?
Follow the manufacturer manual for your specific model. Most fleets we service fall into this range.
Typical Service Intervals
- Every shift: operator daily examination
- Around 250 hours: fluids, filters, visual inspection
- Around 500 hours: expanded service
- Around 1,000 hours: major service
- Around 2,000 hours or annually: comprehensive inspection
Conditions That Shorten Your Intervals
Shorten intervals for cold storage, foundries, dusty or abrasive environments, outdoor yards, and multi-shift operations. Heavy attachment use accelerates mast and hydraulic wear as well.
How to Build a Planned Maintenance Program for Your Fleet
Start With an Asset Inventory
Tag every truck with model, serial number, and current hour meter reading. You cannot schedule around hours nobody is tracking.
Rank Trucks by Criticality
Decide which failures stop production and which are only an inconvenience. Tighten intervals on the first group, then review service history quarterly and adjust.
Key Takeaway: OSHA requires daily examinations and removal of unsafe trucks from service. A maintenance schedule is what makes both routine instead of reactive.
Does OSHA Require Forklift Maintenance?
In part. Under 29 CFR 1910.178, powered industrial trucks must be examined at least daily before being placed in service, and after each shift in operations that run around the clock. Any truck that is not in safe operating condition has to be removed from service, and repairs must be made by authorized personnel.
That standard covers general industry. Construction sites fall under 29 CFR 1926.602. A scheduled program is how many operations meet either set of obligations without relying on memory.
What Skipping Scheduled Service Actually Costs
Run the numbers on one unplanned failure:
- Idled labor rate multiplied by workers affected
- Emergency rental to replace the downed truck
- Expedited freight on parts
- Overtime to recover the missed output
- Late shipment penalties, where applicable
Compare that to a scheduled visit that catches a stretched chain or a weeping cylinder early. In our experience, trucks on a consistent program also come back at trade-in in noticeably better shape than fleets that run to failure.

Questions to Ask Before You Sign a Service Agreement
Not every agreement is built the same. Ask these before committing:
- Are intervals based on hours or calendar dates?
- What is the response time on a breakdown call?
- Are parts included or quoted separately?
- Do I receive written inspection reports?
- Are your technicians trained on my brand of equipment?
- Do you stock parts locally?
- Can you service a mixed-brand or older fleet?
- Is rental equipment available during major repairs?
Pro Tip: Mixed-fleet coverage is the question that trips up most providers. Ask it early, before the pricing conversation starts.
Put Your Fleet on a Schedule
Downtime becomes predictable when maintenance is. Our technicians handle field and shop service across Independence, Lee’s Summit, Olathe, Lenexa, Gardner, Spring Hill, Edgerton, and St. Joseph, backed by a parts department and a rental fleet for coverage during major repairs.
Call RDS Equipment, and we will walk your operation, review your hour meters, and build a planned maintenance program that fits how your trucks actually work.
