What if you had a small cut that wouldn’t stop bleeding?

It would probably worry you. You might wonder about the cause and what other issues it indicated. A quick internet search might give basic guidance, but you would still go see a doctor, no matter how minor the wound. After all, it could be something serious.

Hydraulic fluid is the lifeblood of your forklift’s hydraulic system.

Even a small leak can lead to larger issues. If left long enough, it will put your whole forklift out of commission, leading to expensive emergency repairs and unexpected downtime. It might be a small cut, but it becomes a big issue.

Read on to learn:

  • What makes hydraulic oil leaks dangerous
  • What to do if you have a leak
  • The best way to repair leaks

Can You Drive With a Hydraulic Fluid Leak?

Never continue to use a forklift with a hydraulic fluid leak.

Leaking hydraulic oil might seem like an unimportant issue. Still, it poses a significant risk to your facility, equipment, and associates. Operating a forklift with a leak is just plain dangerous.

  • Fire hazard. Oil is flammable. Excessive heat, sparks, or open flames from a cigarette can easily ignite hydraulic oil leaks. The resulting fires can quickly get out of control.
  • Injury risk. Oil is slick and significantly increases the risk of slips, trips, and falls. These injuries are some of the most common in warehouses and industrial settings. Unattended oil leaks are accidents waiting to happen.
  • Early indicator. Hydraulic oil leaks are an indicator of other problems. Ignored, they can lead to catastrophic failures down the line.
  • Damage to other components. Even if a technician fixes a leak before the forklift fails, continued use of a leaking forklift can damage other components.
  • Braking risk. The forklift's braking distance increases when operating on floors with standing oil, increasing the risk of a collision.
  • Expensive repairs and downtime. Hydraulic leaks are generally inexpensive to fix if caught early. However, the damage they cause leads to costly forklift repairs and revenue lost to unexpected downtime.

There is no upside to ignoring a forklift hydraulic leak.

What Should You Do for Forklifts Leaking Hydraulic Fluid?

Leaks are a relatively common service issue among forklifts.

Fixing them before they become a disaster requires immediate action. So vigilance and prevention are your best tools.

If your forklift has a leak, there are a few steps to take right away.

Spotting Forklift Oil Leaks


You can’t fix a leak you don’t know about.

Keep an eye out for the following signs:

  • Fluid drips or puddles
  • Lower hydraulic fluid levels
  • Unusual sounds
  • Performance issues
  • Running hot

If you notice any of these, remove the forklift from service immediately.

Safety First

Forklift hydraulic fluid can reach 300 degrees Fahrenheit, instantly burning skin even through leather work gloves.

Additionally, hydraulic systems maintain high pressure. This makes it critical to immediately depressurize the system before taking any diagnostic action. Even small leaks can rupture unexpectedly. A rupture during inspection or repair can spray the technician, causing 3rd-degree burns in under a second.

Never inspect or attempt to repair a pressurized hydraulic system.

Hydraulic System Inspection

Once depressurized, you can inspect the hydraulic system for the source of the leak.

A leak can form in a variety of locations. Examine these common failure points:

  • Control valve
  • Lift cylinder
  • Tilt cylinder
  • Hydraulic hoses
  • Auxiliary lines
  • Hydraulic filters
  • Loose nuts
  • Hydraulic fittings

Some leaks are easier to fix than others. For example, tightening a loose nut might fix a small leak. However, most repairs require a certified technician.

Check your warranty before attempting any repairs yourself.

Check Forklift Hydraulic Oil

The vast majority of forklift hydraulic system failures are caused by contaminated fluid.

Check your hydraulic oil for signs of contamination. Replacing dirty fluid isn't likely to fix an existing leak. Still, it can help prevent recurring leaks, reducing repair costs and downtime.

Additionally, routine fluid checks can prevent a leak in the first place.
