5. Health and Safety Information

5.1 General Safety Instructions for Power Tool Use

Warning! Read all safety warnings and instructions. Failure to follow may result in electric shock, fire, or serious injury.

Most important: Know how to safely start and stop the machine, especially in an emergency.

• Keep the work area tidy and clean. Clutter and spills create trip hazards.
• Find a suitable location: good lighting, avoid damp/dusty areas. Do not operate near flammable materials.
• Beware of electric shock: avoid contact with earthed surfaces. Protect the power cable.
• Keep bystanders away: restrict access to the work area.
• Unplug and house unused power tools. Never leave unattended while connected.
• Do not overload or misuse the tool. Use a tool appropriate for the job.
• Dress properly: wear close-fitted clothing, tie back long hair, remove jewellery. Wear fully enclosed footwear with non-slip soles.
• Wear personal protective equipment (PPE): dust mask for dust/fumes, vibration-reducing gloves, safety goggles or face shield. Identify hazards specific to the machine/work process.
• Do not breathe contaminated air: use extraction systems or work outdoors.
• Move the machine as instructed: do not carry by the power cable. Use a second person or mechanical device for heavy items.
• Do not overreach: maintain balance to avoid falls.

Maintain tools correctly: replace damaged parts, keep moving parts clean and oiled. Wait for the machine to stop before making adjustments. Remove setting tools. Prevent unintentional starting by ensuring the switch is OFF before plugging in. Carefully select extension leads: use leads rated for the machine's current and fully extend them. Concentrate and stay alert: never operate under the influence of drugs, alcohol, or when tired. Have the tool repaired by a qualified person using original parts.

5.2 Additional Safety Instructions for Pressure Vessels

• The pressure tank is for static use, charged with natural air within specified limits.
• Ensure tank safety and control devices are efficient and flawless.
• Drain condensation off the tank every day.
• Check for signs of inner corrosion at regular intervals; tank walls should have a minimum thickness of 1.0–2.0mm.
• Any kind of welding to the tank is forbidden.
• Comply with laws on pressure vessel operation in force in the country of use.
• Construction is mainly for permanent load by internal pressure; cyclic loads are limited to 10% PS.

5.3 Connection to the Power Supply

Ensure the power supply information on the machine's rating plate is compatible with your supply. This product comes with a UK standard 3-pin plug, designed for connection to a 230V AC domestic supply. It is Class I (earthed). If an extension lead is required, use an approved, compatible lead and fully extend it. Using a coiled extension lead can cause overheating and fire. This product requires an earth connection.

Ensure the oil level is between the 'MAX' and 'MIN' marks on the vial.

Image Description (Fig.3): Close-up view of the oil level indicator on the compressor, showing the 'MAX' and 'MIN' marks on the vial.

9. Operation

9.1 Installation

Do not tilt the compressor more than 15° in any direction, as this may cause running problems. Allow a minimum gap of 50cm around the compressor for airflow. The compressor can be connected to pneumatic tools and accessories for blowing, washing, and spraying. Connect to an in-line air supply kit with a pressure reducer, lubricator, and separator. Refer to accessory instructions for details.

9.2 Initial Startup - FIGS. 4 - 5

For the first startup, run the compressor for about 10 minutes with air escaping. To do this, pull back the collar on the female air outlet coupling, insert an empty male air line coupling, and release the collar.

After this, stop the compressor, remove the coupling, switch it back on, and allow the tank to fill. The compressor will stop automatically when maximum pressure is reached. Check the pressure on the tank pressure gauge (14).

The operation is controlled by the pressure switch, which stops the motor at maximum pressure and restarts it when pressure drops below a minimum threshold (approx. 2 bar less than max.).

Warning: Never unplug or switch off the main switch to stop the compressor. Always use the pressure switch. Replace the oil after the first 50 working hours.

9.3 Adjusting the Pressure Switch - FIG. 6

This is the only operation where the compressor can be switched off without using the pressure switch. To decrease pressure, run the compressor to the desired capacity, turn off the mains power, and do not operate the red button. Disconnect from power before loosening screw (13.1) to remove the black cover. Adjust the bolt (13.2) anti-clockwise until the switch releases pressure. Replace cover and tighten screw.

To increase pressure, remove the cover (after disconnecting power), turn the adjustment bolt clockwise 3 turns, and replace the cover.

Run the compressor to the desired capacity, turn off mains power, and disconnect from supply. Remove cover and adjust bolt anti-clockwise until pressure is released. Replace cover and tighten screw.

Image Description (Fig.6): Diagram showing the pressure switch with adjustment screw (13.2) and cover screw (13.1).

9.4 Overload Cut-Out - FIG. 7

The compressor has an overload cut-out (8) to protect the motor from overload or overheating. The device automatically disconnects the compressor. To restart:

• Allow three minutes.
• Position the pressure switch to “0” OFF.
• Manually reset the thermal cut-out (8).
• Position the pressure switch to “1” ON.

If the overload cut-out releases again, turn the main switch OFF, unplug the equipment, and contact an Authorised Service Centre.

Note: After reconnection, ensure the tap is opened. Connect an air line filter separator and lubricator for a good, clean air supply. If using a spray gun, use only a filter separator to prevent lubrication contamination.

10. Troubleshooting

USE ONLY ORIGINAL SPARE PARTS, AVAILABLE FROM AUTHORIZED SERVICE AGENTS.

11. Maintenance

Some operations require returning the compressor to an authorised service agent. Before any service, ensure power is cut off and all pressure is released from the tank. Ensure all components are fitted correctly after maintenance.

11.1 Operations to be Carried Out After the First 50 Working Hours

Check that all screws and bolts are tight, especially on the head and crank case. Replace the lubricant. Do not mix oils; use quality oils with good lubricating properties. Dispose of oil correctly according to local authority regulations.

11.2 Weekly Operations

Check the oil level and top up if necessary, without exceeding the 'MAX' mark. Ensure the oil does not drop below the 'MIN' mark. Drain condensation daily by opening the valve (1) located under the tank. Turn the valve anti-clockwise with a container underneath. Keep the compressor positioned to allow complete drainage.

Image Description (Fig.8): Close-up of the drain valve (labeled ①) located under the compressor tank.

11.3 Monthly Operations (or more frequently if the compressor operates in very dusty areas) - FIG. 9

Remove the air filter (9) and clean or replace the element. Do not operate the compressor without the air filter fitted, as foreign bodies or dust can damage internal components.

Image Description (Fig.9): View of the air filter (labeled 9) on the pump unit.

11.4 Operations to be Carried Out Every 6 Months - FIGS 10 - 12

Unscrew the oil dipstick and remove the drain plug (7) to change the oil into a suitable container. Perform this when the compressor is hot for rapid and complete drainage. Pour new oil via the oil dipstick hole up to the 'MAX' level.

Clean all finned parts to maintain efficient cooling and a long working life. Check belt tension: the belt should flex about 10mm when a weight of about 3kg is applied at its midpoint. Tension the belt if necessary, taking care not to disturb pulley-to-flywheel alignment.

Image Description (Fig.11): Illustration of checking the belt tension on the compressor's pulley system.
Image Description (Fig.12): Hand adjusting the air filter element.

11.5 Operations to be Carried Out Every 2 Years

Check the non-return valve and replace the seal if necessary. Check intake and delivery valves in valve plates.

11.6 Recommended Oils

Recommended oils with ISO grade 100 for compressors, in accordance with DIN 51506 Standard (suitable for room temperature ranging from +6°C and +25°C). Use oils with an ISO grade 46/68 for room temperature ranging from 0°C to +5°C. Use oils with an ISO grade 150 for room temperature ranging from +26°C to +45°C.
