Setup
- Unpacking: Carefully remove the compressor from its packaging. Inspect for any shipping damage.
- Placement: Place the compressor on a stable, level surface. Ensure adequate ventilation around the unit.
- Power Connection: Connect the compressor's power cord to a grounded 120 Volt AC outlet. The 1.5 max HP (running) motor draws only 12 amps, allowing for easy startup without tripping circuit breakers, even with a 14 GA or larger extension cord up to 50 ft. (15.2 m).
- Hose and Tool Connection: Attach your air hose to the universal female coupler on the compressor. Connect your desired pneumatic tool (e.g., finish nailer, stapler) to the other end of the air hose.
Operating Instructions
- Power On: Flip the ON/OFF switch to the "ON" position. The LED will illuminate, indicating the compressor is active. The compressor will begin to build pressure in the tank.
- Set Output Pressure: Use the pressure regulator knob on the control panel to adjust the output air pressure to the desired PSI for your tool. Monitor the regulated pressure gauge. The compressor can deliver up to 150 PSI max.
- Operation: Once the tank pressure reaches its maximum (150 PSI) and the regulated pressure is set, you can begin using your pneumatic tool. The compressor will automatically cycle on to maintain tank pressure as air is consumed.
- Power Off: When finished, flip the ON/OFF switch to the "OFF" position. Disconnect the air hose and unplug the power cord.
- Drain Tank: Always drain the air tank after each use to prevent moisture buildup and corrosion. Locate the drain valve at the bottom of the tank, open it to release air and moisture, then close it securely.
Maintenance
The BOSTITCH CAP1512-OF features an oil-free pump, significantly reducing maintenance requirements.
- Daily: Drain the air tank to remove accumulated moisture.
- Regularly: Inspect the air filter for dirt and debris. Clean or replace if necessary to ensure optimal airflow.
- Periodically: Check all hoses and fittings for leaks or damage. Tighten any loose connections.
- Storage: Store the compressor in a clean, dry environment. Utilize the integrated cord wrap and on-board storage pocket for neat organization.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not start or run. | No power, tripped circuit breaker, faulty switch. | Check power connection, reset breaker, ensure ON/OFF switch is engaged. |
| Compressor runs continuously or cycles too frequently. | Air leak in hose/fittings, drain valve open, excessive air demand. | Check for leaks, close drain valve, reduce air consumption. |
| Low air pressure at tool. | Regulator set too low, air leak, clogged air filter. | Adjust regulator, check for leaks, clean/replace air filter. |
| Excessive noise or vibration. | Loose components, worn parts. | Inspect and tighten all fasteners. If problem persists, contact customer support. |
