How to Maintain a Jack: Inspection, Storage, and Safe Use Checks

Jack maintenance keeps lifting predictable and reduces the risk of leaks, slipping, corrosion, or sudden failure. The exact maintenance method depends on the jack type, but the basic checks are similar: keep it clean, inspect before use, protect moving parts, and store it correctly.

Relevant product category: jacks series.

Before use

Check the rated capacity, base, lifting point, saddle or toe, handle, release valve, screw, frame, and any visible damage. Do not use a jack if it is bent, leaking, cracked, unstable, or missing markings.

Hydraulic jack checks

Hydraulic jacks need attention to oil level, seals, cylinder condition, release valve behavior, and smooth lifting/lowering. If the jack feels spongy or cannot hold pressure, remove it from service until inspected.

Mechanical jack checks

Mechanical jacks need attention to screw threads, gears, pawls, lubrication, handle fit, and deformation. Dirt and corrosion can make operation rough and unsafe.

Storage

Store jacks in a clean, dry place. Keep hydraulic jacks in the recommended position and protect them from dust, moisture, and impact.

Safety boundary

A jack is for lifting or positioning. Use proper support equipment before working near or under a raised load.
