GENMA Maintenance · Hydraulic System | Cylinder Care: Keep It Clean, Keep It Going

Cylinders lift, luff, and move your GENMA machine. Their life depends on the piston rod and seals.

Daily checks
•    Look — scratches, rust, or dents?
•    Leaks — oil around the rod seal or fittings?
•    Listen — squeaking or clicking?

Keep the rod clean
•    Wipe regularly with a clean cloth.
•    Long-term storage? Apply grease and wrap with plastic film.
•    Before restarting, extend and retract 2–3 times.

Change seals every 2 years
•    Rubber ages. Use GENMA genuine seal kits. Have a pro do it.

Lubricate spring lubricators (if equipped)
•    Every 500 hours.

A clean rod is a happy rod. No welding, no drilling, no scratches. Don't ignore leaks — they only get worse.

Simple care now saves big trouble later.
