2. Veiligheidsinligting
Volg altyd die volgende veiligheidsmaatreëls om beserings of skade aan die toerusting te voorkom:
- Elektriese veiligheid: Ensure the compressor is connected to a properly grounded electrical supply matching the specified voltage (208-230V or 460V). Disconnect power before performing any maintenance or service.
- Drukveiligheid: Moet nooit die maksimum bedryfsdruk van 175 PSI oorskry nie. Moenieamper with the safety relief valve.
- Bewegende dele: Keep hands, hair, and clothing clear of moving parts such as belts and pulleys. The belt guard must always be in place during operation.
- Warm oppervlaktes: The compressor pump and discharge lines can become very hot during operation. Avoid contact to prevent burns.
- Ventilasie: Operate the compressor in a well-ventilated area to prevent the accumulation of carbon monoxide and to ensure proper cooling.
- Dreinering: Regularly drain condensate from the air tank to prevent corrosion and maintain air quality.
- Persoonlike Beskermende Toerusting (PPE): Wear appropriate safety glasses or goggles, hearing protection, and other necessary PPE when operating or servicing the compressor.

4.1 Begin die kompressor
- Ensure all connections are secure and the power supply is connected.
- Open the air outlet valve slightly to allow the compressor to start without full load.
- Turn on the main power switch. The compressor will start automatically and build pressure.
- Once the desired pressure is reached, the compressor will shut off automatically due to the auto start/stop pressure switch operation.
4.2 Aanpassing van Druk
The operating pressure can be adjusted using the pressure regulator, typically located near the pressure gauge. Turn clockwise to increase pressure and counter-clockwise to decrease pressure. Monitor the pressure gauge during adjustment.
4.3 Afskakel
- Skakel die hoofskakelaar uit.
- Close the air outlet valve.
- Bleed any remaining air pressure from the tank using the manual condensate drain or an air tool connected to the outlet.
5. Onderhoud
