Forklift Jack for Forklift

Frequently Asked Questions

Q: What is the lifting capacity of the FJ FLJ4 forklift jack?
A: The FJ FLJ4 is a manual or hydraulic jack with a standard 4-ton lifting capacity at full extension. This capacity assumes level, stable ground. Do not exceed the rated load as this can cause internal seal failure and loss of lift pressure.

Q: Which forklift models are compatible with the FJ FLJ4?
A: FJ FLJ4 fits most sit-down and stand-up electric and gas forklifts from Crown, Toyota, Raymond, Yale, and Hyster in the 4-5 ton class. Verify your lift truck has a compatible frame pocket or saddle before ordering.

Q: What hydraulic fluid type does the FJ FLJ4 use?
A: The FJ FLJ4 uses standard ISO 46 hydraulic fluid. Check your equipment manual for the exact specification. Using incorrect fluid can damage seals and reduce lift performance. Keep the reservoir full and change fluid per maintenance intervals.

Q: How often should the FJ FLJ4 be serviced?
A: Inspect the FJ FLJ4 annually for leaks, corrosion, and seal wear. Check hydraulic hoses for cracks or bulging. If the jack does not hold pressure or lifts slowly, internal seals may be worn and require replacement.

Q: What is the difference between FJ FLJ4 and FJ FLJ4-STAND?
A: The FJ FLJ4 is the jack unit alone. The FJ FLJ4-STAND includes the jack plus a set of support stands. The standalone jack is used when you already own compatible stands; the combo SKU is for customers who need both components together.
