Gardner Denver Base Mounted Compressor L90

Danger! Air/oil under pressure will cause severe personal injury or death.

Shut down the compressor, relieve the system of all pressure, disconnect, lockout and tagout the power supply to the compressor package before removing valves, caps, plugs, fittings, bolts and filters.

Caution! Fire hazard and slip hazard!

Oil residue and other deposits must be removed from the compressor coolers which are exposed to hot air in accordance with the user manual.

Look for leaks! Immediately take care of any spilled oil!

Turn off the screw compressor unit, secure it against accidental restarts and make sure that the demister vessel is depressurized.

Slowly open the oil screw plug to relieve the screw compressor of any residual pressure in the system

High voltage – Hazard of shock, burn, or death

 Be careful with electricity: only work on screw compressors which are not powered.

 Only for L90RS-L132RS: There is a risk of electric shock from charged capacitors! Disconnect the systemfrom the mains and wait 10 minutes before touching electrical components.

The power capacitors need this time to discharge.

Every 4000 hours operation or 12 months

1. Visually check for leakage on the shaft seal,replace as required.

The tool kit is required to change the oil seal. If the oil seal is a lip seal, the wear sleeve must always be replaced.

2. Replace lubricant every 8000 hours. Under adverse conditions, change more frequently. Flush system if required.

Danger! Air/oil under pressure will cause severe personal injury or death. Shut down the compressor, relieve the system of all pressure, disconnect, lockout and tagout the power supply to the compressor package before removing valves, caps, plugs, fittings, bolts and filters.

CAUTION! Fire hazard and slip hazard! Do not spill any oil! Look for leaks! Immediately take care of any spilled oil!

NOTICE! Do not mix oils with different specifications. If the compressor system is delivered without oil, oil must first be filled into the pressure reservoir up to the “maximum oil level” mark.

Shut off the compressor with the STOP button.

Wait at least 5 minutes until the oil has settled, i.e. until the air has bubbled out.

Check the oil level at each pause in operation and at regular intervals using the transparent plastic tube on the pressure reservoir.

The oil level must lie between the “maximum oil level” and “minimum oil level” marks on the oil container.

If required, top up oil. Use Gardner Denver oil only.

Close the oil filler cap firmly.

When checking pressure relief valve thereis an explosive release of pressure.

Failure to perform this operation in a safe manner or without safety equipment may result in personal injury ordeath.

 Use the appropriate safety equipment, hearing and eye protection, and use safety precautions when performing this PRV check on an operating machine.

Testing the pressure relief valve

1. On a separate compressed-air system.

2. When raising the system operating pressure toits normal level.

Danger! Air/oil under pressure will cause severe personal injury or death. Shut down the compressor, relieve the system of all pressure, disconnect, lockout and tagout the power supply to the compressor package before removing valves, caps, plugs, fittings, bolts and filters.

NOTICE!: Dispose of the oil filter cartridge properly - it is hazardous waste! Look for leaks!
