normal operating pressure.
Refer to technical
specifications on page 6.
2. Pressure switch is not
operating properly.
SOLUTIONS
1. If pressure drops too
low, adjust the pressure
regulator knob while using
the air tool.
2. Check the air requirement
of air tool. Refer to
technical specifications
on page 6. If it is higher
than CFM and pressure
supplied by compressor,
use a compressor of high
capacity. Most tools are
rated at 25% of actual
CFM while running
continuously.
