- Atharrachadh cuideam: The black box (Figure 3) automatically turns the compressor on and off to maintain tank pressure.
- Tomhas Brùthadh Tanca: Displays the current pressure inside the air tank (Figure 2).
- Working Pressure Gauge: Displays the pressure of the air being supplied to your tools, adjustable via the regulator (Figure 2).
- Riaghladair cuideam: The red knob (Figure 3) allows you to adjust the working pressure. Turn clockwise to increase pressure, counter-clockwise to decrease.
- Quick-Connect Air Outlet: For attaching air hoses and tools (Figure 3).
A 'tòiseachadh air an compressor
- Dèan cinnteach gu bheil am bhalbha drèanaidh aig bonn an tanca dùinte.
- Plug the compressor into a suitable power outlet.
- Turn the main power switch to the "ON" position. The compressor will start to build pressure.
- Once the tank reaches its maximum pressure, the compressor will automatically shut off.
Connecting and Using Air Tools
- Connect your air hose to the quick-connect air outlet.
- Attach your air tool to the other end of the hose.
- Adjust the working pressure using the red regulator knob to suit the requirements of your air tool. Monitor the working pressure gauge.
- Begin using your air tool. The compressor will cycle on and off automatically to maintain pressure as needed.
A' Sguabadh sìos
- Turn the main power switch to the "OFF" position.
- Dì-cheangail am pìob adhair agus na h-innealan.
- Fosgail am bhalbh drèanaidh aig bonn an tanca gu slaodach gus taiseachd dùmhail agus cuideam èadhair sam bith a tha air fhàgail a leigeil ma sgaoil. Dùin am bhalbh aon uair ‘s gu bheil an tanca falamh.
Cumail suas
Bidh cumail suas cunbhalach a’ dèanamh cinnteach gum mair an compressor adhair agad fad-beatha agus gum bi e ag obair gu sàbhailte.
Gach latha / às deidh gach cleachdadh
- Dùmhlachd drèanaidh: After each use, or daily if used frequently, open the drain valve at the bottom of the air tank to release accumulated moisture. This prevents rust and corrosion inside the tank.
Weekly/Monthly
- Dèan sgrùdadh air criathar adhair: Check the air filter for dirt and debris. Clean or replace if necessary to ensure proper airflow to the pump.
- Thoir sùil airson Leaks: Listen for any air leaks around fittings, hoses, and valves. Tighten connections as needed. A soapy water solution can help identify small leaks.
- Dèan sgrùdadh air pìoban agus uidheaman: Examine air hoses for cracks, cuts, or wear. Replace damaged hoses immediately. Ensure all quick-connect fittings are functioning correctly.
- Dèan sgrùdadh air sreang cumhachd: Check the power cord for any damage, fraying, or exposed wires.
Gach bliadhna
- Sgrùdadh Tanca: Visually inspect the air tank for any signs of external corrosion, dents, or damage. If any damage is found, do not use the compressor and seek professional inspection.
- Sgrùdadh Bhalbhaichean Sàbhailteachd: Briefly pull the ring on the safety relief valve to ensure it operates freely and reseats properly.
For any maintenance beyond these basic steps, it is recommended to consult a qualified service technician.
