Pallet Jack Maintenance: A Practical Guide for Manual and Electric Trucks
A pallet jack fails at the worst possible moment — mid-shift, mid-aisle, under load. A few minutes of routine upkeep is what keeps that from happening.
What is a pallet jack?
A pallet jack (also called a pallet truck) is the most basic type of forklift, used to lift and move pallets over short distances inside a trailer or warehouse. Both manual and powered versions are used to load and unload trucks, and electric models with drive wheels can also move pallets horizontally around a facility. Pallet jacks are among the most essential pieces of material handling equipment in any warehouse — they make it easy to transport heavy loads, which improves efficiency and reduces the risk of injury to workers. Like any equipment, though, they need regular upkeep to keep doing that safely.
Types of pallet jacks
- Manual (standard) pallet jacks: hand-powered jacks most common in retail and personal warehousing operations, used for lifting, lowering, and steering pallets from one place to another.
- Motorized (electric) pallet jacks: also called electric pallet trucks, walkies, or power jacks — motorized to lift and move heavier and stacked pallets. A throttle on the handle drives forward or reverse; the jack is steered by swinging the handle.
- Corrosion-resistant pallet jacks: built for settings with regular exposure to corrosive chemicals and water, such as moving fish, meat, or poultry. Stainless steel and galvanized steel are the most effective materials for this resistance.
- Custom pallet jacks: a standard design doesn’t work for every operation — custom jacks let you match fork height, width, and materials to your warehouse’s specific size and function.
Pallet jack vs. forklift
Both are material handling equipment used to move heavy loads, but they serve different jobs. A forklift is a larger, more powerful vehicle for loads too heavy for a person to lift alone, using a set of prongs (forks) to lift and move the load. A pallet jack is smaller and less powerful, built for lighter loads a single person can move, using forks to lift and transport a pallet — the platform goods sit on.
Daily checks and component-level maintenance
The highest-value pallet jack maintenance happens before each shift, in under two minutes. Operators should confirm the jack lifts and lowers smoothly, rolls straight, and stops when expected — and pull it from service the moment any of those fail. Beyond the daily walk-around, each component has its own upkeep rhythm:
| Component | Maintenance task | Frequency |
|---|---|---|
| Hydraulic pump | Check for leaks and spongy lift; confirm forks hold load without drift; top up or bleed fluid as needed | Weekly / as needed |
| Wheels & rollers | Clear wrapped shrink-wrap and debris; check for flat spots, cracks, and free rotation; replace worn polyurethane | Weekly |
| Forks | Inspect for bends, cracks, and welds; verify entry/exit rollers move freely | Daily walk-around |
| Grease points & linkage | Lubricate steer axle, load wheel links, and pump pivot points | Monthly |
| Battery (electric) | Check charge level and connections; water lead-acid cells; charge fully, avoid partial top-offs | Per shift / weekly |
| Brakes & controls (electric) | Test brake engagement, throttle response, horn, and emergency reverse (belly button) | Daily walk-around |
Protect the wheels
The wheels depend heavily on the surface they’re used on. Wire, strapping, and other debris can wedge between the wheels and wear them out much faster — routine wheel cleaning and sweeping debris before use largely prevents this. Watch for curbs and steps, too: it takes longer, but two trips instead of one keeps a wheel from forming a flat spot, and gets more life out of it.
Check the forks for wear
Forks carry heavy loads every day, so they’re the part most prone to wear if neglected. Inspect them daily for chipping, buckling, or bending, and report any structural damage immediately — paint chips are normal, but bends or cracks aren’t.
Verify the chain position
Confirm the chain is still seated correctly on a regular basis. A common symptom of a slipped chain is the forks no longer lowering when the lowering valve is operated — reconnecting the chain to the lever is usually a quick fix.
Check the hydraulic system
A manual pallet truck uses a hydraulic pump to raise and lower the load, and it needs the same ongoing care as any other component. Check daily for leaks and damage. If air gets trapped in the pump, the jack will struggle to lift — pumping the lever about ten times usually clears it.
Verify and refill the oil
Top off or replace the hydraulic oil roughly once a year, and check the level every six months. Most pallet trucks call for hydraulic oil around 0.4 liters total, with a viscosity of 30cSt at 40°C (ISO VG32) — check the manufacturer’s spec, since a thicker oil makes the truck harder to pump.
Lubricate regularly
The manufacturer greases all bearings and axles with long-life grease at the factory. Reapply long-life grease to the wheels, axles, and grease fittings once a month and/or after each cleaning.
Recharge electric batteries
Fully charge an electric pallet jack’s battery before operation — a partial charge risks downtime mid-shift.
Common pallet jack problems and how to fix them
The most common pallet jack failures are a jack that won’t lift, one that won’t lower, leaking hydraulic fluid, and flat-spotted or seized wheels. Most trace back to fluid or debris and are fixable in-house before they force a replacement.
- Won’t lift or lifts partway: usually low hydraulic fluid or air trapped in the pump. Top up the fluid and bleed the system by working the handle with the lower valve open.
- Won’t lower: a bent release lever, misadjusted linkage, or debris in the valve — or, as above, a slipped chain. Check and reset the lowering adjustment before assuming the pump is bad.
- Leaking fluid: a worn seal or overfilled reservoir. Replace the seal kit; don’t just keep refilling a leaking unit.
- Flat-spotted or noisy wheels: from parking under load or hardened debris. Replace polyurethane wheels in pairs so the jack tracks straight.
- Electric: short runtime or won’t hold charge: often a battery kept in partial-charge cycles. Correct charging habits first, then load-test the battery.
The same discipline that keeps larger lift trucks running applies here — see our guide to common forklift problems for the failures that carry over across your material handling fleet.
A preventive maintenance schedule for pallet trucks
A workable PM schedule for pallet jacks runs on three intervals: a daily operator check, a monthly hands-on service, and an annual inspection. That cadence catches wear early without pulling equipment out of service unnecessarily.
- Daily (operator): lift/lower test, roll and steer check, fork and wheel look-over, chain position, and — on electric units — brakes, controls, and charge level.
- Monthly (technician): grease all pivot and linkage points, inspect hydraulic fluid, check wheel wear, and tighten fasteners. Water and clean electric battery terminals.
- Annually: full teardown inspection of the pump, seals, and frame welds; verify or replace hydraulic oil; load-test the hydraulics; capacity-check and, if needed, replace electric batteries.
Running these intervals consistently is exactly what a preventive maintenance system is built to enforce — so the monthly service never quietly slips a quarter behind.
Using a pallet jack safely
A pallet jack may not look like the most dangerous piece of equipment, but crushed toes, trip hazards, scratched knuckles, and twisted backs are all real risks without a few basic precautions.
Before you start
- Give the jack a general inspection to confirm it’s in good operating order, and check that the controls are responsive and undamaged.
- Check the wheels for cracks or wear — worn wheels handle sloppily and raise the odds of the load becoming unstable mid-move.
- Inspect the pallet itself for loose or rotting sections, and check that no leakage from a prior load has weakened its structure. Store pallets somewhere dry.
Personal protective equipment
- Protective eyewear to guard against material strapping and any hazardous chemicals being moved.
- Safety-toed footwear to prevent foot injuries from the wheels, falling materials, or a stubbed toe.
- Gloves to reduce cuts, bruises, blisters, and smashed fingers.
While operating
- Never put your feet beneath a pallet jack, and check the floor for ruts, bumps, and other flaws before moving.
- Never exceed the jack’s rated load capacity, and never use it to transport people.
- Push, don’t pull, when going down an incline, and avoid slopes where the jack could reverse and hit something if released.
- Use a spotter if your view is restricted, and move loads slowly so you can react if your surroundings change.
- Stay alert for pinch points, stick to correct traffic lanes, and watch for collisions around corners.
- Confirm the path is clean, flat, and free of obstacles before moving a load, and use proper lifting technique when loading and unloading.
Storage
Store pallet jacks somewhere they won’t create a tripping hazard when not in use, and never let them block emergency resources like fire extinguishers or exits.
Manual vs. electric: which pallet jack fits your operation?
Electric pallet jacks are, at their core, manual pallet jacks with automation added. Each comes with real tradeoffs.
Manual pallet jacks
Pros: lower maintenance costs, since there are no electrical parts to service and replacement parts are easier to source; a tough, simply-built truck that holds up well to demanding facilities; easy to customize with different fork heights, widths, and materials for dry or wet areas; and a lower purchase price, which is why manual models are more common overall.
Cons: more physically demanding and less comfortable to maneuver, since a person supplies all the power; more worker fatigue and injury risk over a shift; and a practical weight limit — even a jack rated for 5,000 lbs may exceed what a worker can move manually.
Electric pallet jacks
Pros: less physical strain, since aided lifting does the work; higher productivity, moving, lifting, and lowering pallets faster than manual models; and easier handling of heavy loads, since the motor does the lifting.
Cons: higher upfront cost, though it can pay for itself through productivity gains; more maintenance and repair complexity and cost; and more operator training required before use.
Why maintenance software helps
A CMMS gives pallet jack maintenance a centralized, organized system instead of memory and paper. It lets you build a schedule for recurring tasks — like lubricating wheels or checking hydraulic fluid — and track when each pallet jack or truck was last serviced, so you always know what’s due. When something does break down, the same system helps you quickly log the issue and schedule the repair, minimizing downtime. Over time, it also surfaces the data — cost and frequency of maintenance tasks per asset — that helps you spot which units are becoming a maintenance drain versus which are running clean.

Frequently Asked Questions
How often should a pallet jack be serviced?
Give every pallet jack a daily operator check, a monthly hands-on service (grease, fluid, wheel wear), and a full inspection annually. High-use electric units in multi-shift operations may need monthly tasks moved to a two-week cycle.
Why won’t my pallet jack lift?
The most common cause is low hydraulic fluid or air trapped in the pump. Top up the fluid, then bleed the system by pumping the handle with the release valve open. If it still won’t lift or hold a load, the pump seals likely need replacing.
What’s the difference between a pallet jack and a forklift?
A forklift is larger and more powerful, built to move loads too heavy for a person to lift alone. A pallet jack is smaller, built for lighter loads a single person can move, and is generally used for shorter-distance work like loading and unloading trailers.
What maintenance does an electric pallet jack need that a manual one doesn’t?
Electric pallet trucks add battery care (correct charging, watering lead-acid cells, checking connections) plus brake, throttle, and controller checks. The hydraulics, wheels, and forks are maintained the same way as on a manual jack.
Can a CMMS track pallet jack and forklift maintenance together?
Yes. A CMMS manages all material handling equipment in one system — scheduling recurring PMs, logging repairs, and tracking parts and costs per asset — so pallet jacks, forklifts, and the rest of your fleet share one maintenance history.
