Porter-Cable CF1540 - Operating Procedures

c. Turn the drain valve (J) Fig. 2, opening it fully, to prevent air pressure
build-up in the tank.
d. Move the pressure switch lever to “ON/AUTO”. The compressor will
start.
e. Run the compressor for 15 minutes. Make sure the drain valve is open
and there is no tank pressure build-up.
f. After 15 minutes, close the drain valve by turning knob. The air
receiver will fill to cut-out pressure and the motor will stop. The
compressor is now ready for use.
OPERATING PROCEDURES
Preparation for Use:
1. Before attaching air hose or accessories, make sure the OFF/AUTO lever
is set to “OFF” and the air regulator is closed.
2. Inspect air intake filter (H) Fig. 1. Clean or replace as necessary.
3. Attach hose and accessories.
WSDMEM TOO MUCH AIR PRESSURE CAUSES A HAZARDOUS
RISK OF BURSTING. CHECK THE MANUFACTURER’S MAXIMUM
PRESSURE RATING FOR AIR TOOLS AND ACCESSORIES. THE
REGULATOR OUTLET PRESSURE MUST NEVER EXCEED THE
MAXIMUM PRESSURE RATING OF THE TOOL BEING USED.
4. Turn the OFF/AUTO lever to “AUTO” and allow tank pressure to build.
Motor will stop when tank pressure reaches “cut-out” pressure.
5. Open the regulator by turning it clockwise. Adjust the regulator to the
correct pressure setting. The compressor is ready for use.
6. Always operate the air compressor in well ventilated areas; free of
gasoline or other solvent vapors. Do not operate the compressor near the
spray area.
After Use:
7. Set the “OFF/AUTO” lever to “OFF”.
8. Turn the regulator counterclockwise to set the outlet pressure to zero.
9. Remove the air tool or accessory.
10. Pull ring on safety valve (K) Fig. 3, allowing air to bleed from the tank until
tank pressure is approximately 20 psi. Release safety valve ring.
11. Drain water from air tank. Turn drain valve (J) Fig. 2, counterclockwise, to
open.
CBM WATER WILL CONDENSE IN THE AIR TANK. IF NOT
DRAINED, WATER WILL CORRODE AND WEAKEN THE AIR
TANK CAUSING A RISK OF AIR TANK RUPTURE.
NOTE: If drain valve is plugged, pull ring on safety valve (K) Fig. 3,
and hold until all air pressure has been released. The valve can then
be removed, cleaned, and reinstalled.
12. After the water has been completely drained, turn drain valve to close.
The air compressor can now be stored.
