Porter-Cable CF1540 - Duty Cycle; Specifications

GLOSSARY
SCFM or CFM: Standard Cubic Feet per Minute; a unit of measurement of
air delivery.
PSIG or PSI: Pounds per square inch gauge.
CUT-IN PRESSURE: While the motor is off, air tank pressure drops as you
continue to use your accessory. When the tank pressure drops to
approximately 100 PSI the motor will restart automatically. The low pressure
at which the motor automatically re-starts is called “cut-in pressure.”
CUT-OUT PRESSURE: When you turn on your air compressor and it begins
to run, air pressure in the air tank begins to build. It builds to approximately
125 PSI before the motor automatically shuts off. The high pressure at which
the motor shuts off is called “cut-out pressure.”
DUTY CYCLE
Porter-Cable air compressors should be operated on not more than a 50%
duty cycle. This means an air compressor that pumps air more than 50% of
one hour is considered misused, because the air compressor is undersized
for the required air demand. Maximum compressor pumping time per hour is
30 minutes.
STORAGE
When you have finished using the air compressor:
1. Set the “ON/OFF” switch to “OFF” and unplug the cord.
2. Review the “Operating Procedures” section. Be sure to drain the water
from the air tank.
3. Protect the electrical cord and air hose from damage by winding them
loosely around the air compressor.
4. Store the air compressor in a clean and dry location.

* A circuit breaker is preferred. Use only a fuse or circuit breaker that is the same rating as
the branch circuit the air compressor is operated on. If the air compressor is connected to a
circuit protected by fuses, use time delay, type ‘T’ fuses.
