GENMA Maintenance · Hydraulic System | Leak Check: A Small Drip Can Be a Big Warning

Your GENMA machine’s hydraulic system is its powerhouse. Spot an oil stain on the ground or notice slower operation? Don’t shrug it off — that could be your system crying for help.

How to spot a leak

Check the ground — Before starting your shift, take a quick look under the machine. Fresh oil stains mean a leak is already there.

Check the hoses and pipes — Look for oil droplets on hydraulic hoses, steel tubes, and fittings, especially around bends and connections.

Check the oil level — If the tank level keeps dropping but you see no external leak, the problem might be internal (like worn piston seals in a cylinder).

Common leak spots

• Hose fittings — Vibration can loosen nuts over time

• Cylinder piston rods — Worn seals cause oil to seep out

• Pump and motor shaft seals — Leaks develop as seals wear

What to do when you find a leak

• Light seepage — Clean the area and monitor it for a few days. If it persists, tighten the fitting or replace the seal.

• Active dripping — Stop the machine immediately, release pressure, then repair. Don’t run with a leak — it only gets worse.

• High-pressure spray — Oil can jet out from a tiny hole. If you see a mist-like spray, do not touch it. Shut down and step away immediately.

Hydraulic oil leaks waste fluid, harm the environment, and can lead to pressure loss, poor lubrication, or even fire hazards. Take one minute each day to look — and even smell — for oil. Early detection saves you from big trouble later.
