Key points for oil cylinder maintenance

-- Protect the Rod Surface
Avoid collisions or scratches on the piston rod to prevent seal damage.

-- Regularly Clean
Regularly clean the dust seals and surrounding areas to prevent contamination inside the cylinder.

-- Check and Tighten Connections
Inspect all connection points for looseness and tighten them in time to prevent oil leakage.

-- Ensure Proper Lubrication
Keep components well-lubricated to reduce corrosion and wear.

-- Maintain Hydraulic Oil Cleanliness
Replace hydraulic oil and clean the filter screen regularly to maintain a clean system.

-- Control System Temperature
Prevent high temperatures to avoid seal aging and damage.

-- Pre-Run Before Operation
Run the full stroke before each use to release trapped air and preheat the system, avoiding hydraulic shock.

-- Release Pressure After Use
After work, release the cylinder  pressure to prevent long-term compression of seals and extend cylinder life.
