6 MONTH MAINTENANCE
Pressure check all valve and internal seals. Replace as required.
Check Ram feet for damage and wear.
Pressure check all valves and internal seals. Replace as required.
Check operating pressure, unloaded through full operating cycle.
Check Ram feet for chips, cracks or other damage.
Check opening and closing times.
Replace operating decals, if necessary.
Replace hoses, couplings and fasteners as required.
Clean and lubricate Ram.
Protect unit against moisture.
Store in adequate space to prevent damage to hoses, connectors or Ram
itself.
