Quick Answer

Before using your 50L air compressor for the first time, check the oil level, ensure all components are correctly assembled, place the compressor on a stable surface, and verify the electrical supply is suitable. Completing these checks will help ensure safe and reliable operation.

Tip: Always keep the compressor upright during transport and use to prevent oil leakage.

Before You Begin

Before connecting your compressor to the mains power supply:

• Read and understand the user manual.
• Check that all supplied components have been fitted correctly.
• Place the compressor on a flat, stable surface.
• Ensure the surrounding area is clean, dry and well ventilated.

Important: Never operate the compressor without the correct oil level or with missing components.

1. Check the Oil Level

Before every use:

• Keep the compressor in an upright position.
• Check that the compressor contains sufficient oil (the compressor is supplied pre-filled with oil).
• Ensure the oil level is within the recommended range shown on the oil sight glass or dipstick (depending on model).

If this is the first time using the compressor:

1. Remove the transport cap from the oil fill opening.
2. Install the supplied oil filler plug.
3. Tighten the plug securely.

2. Assemble and Inspect the Compressor

Before switching the compressor on, check that:

• The wheels are securely fitted.
• The support feet are correctly installed.
• Both air filters are fitted and securely tightened.
• All supplied components have been assembled correctly.
• No parts are loose or damaged.

Refer to your user manual for the complete parts list if required.

3. Position the Compressor Correctly

For safe operation:

• Place the compressor on a firm, level surface.
• Ensure it cannot move during operation.
• Do not position it near the edge of a bench or platform.
• Leave at least 1 metre of clearance around the compressor, particularly from walls or other objects.
• Make sure all cooling vents and air openings remain unobstructed.

Operate the compressor only in:

• A dry environment.
• A clean, dust-free area where possible.
• A well-ventilated location.

Important: Never operate the compressor in wet conditions.

4. Check the Electrical Supply

Before plugging the compressor in:

• Avoid using long extension leads or cable reels wherever possible.
• Connect the compressor to a suitable mains power supply.
• Use a Residual Current Device (RCD) with a maximum trip current of 30 mA for additional protection against electric shock.

When the compressor starts, you may notice a brief voltage drop. This is normal and may cause nearby lights to flicker, particularly where the mains supply quality is poor.

You're Ready to Start

Once you have completed all of the checks above, your compressor is ready to use.

Frequently Asked Questions

Does my compressor already contain oil?

Yes. The compressor is supplied with oil, but you should always check the oil level before first use and before each subsequent use.

Why must the compressor remain upright?

Keeping the compressor upright prevents engine oil from leaking into areas where it should not be and helps avoid damage during transport and operation.

Can I use an extension lead?

Where possible, avoid using long extension leads or cable reels as they can reduce performance. If one is required, ensure it is fully unwound and suitable for the compressor's power requirements.

Why should I use an RCD?

An RCD provides additional protection against electric shock by disconnecting the power supply if a fault is detected.

How much space should I leave around the compressor?

Leave at least 1 metre of clear space around the compressor to allow adequate ventilation and cooling.
