Speedaire Operating Instructions
Oil-Lubricated Series
Operation (Continued)
6. Unplug power cord.
7. Close drain valve.
The compressor is now ready for use.
OPERATING PROCEDURE
1. Turn switch to OFF position and plug
in power cord.
2. Turn regulator knob
counterclockwise to close air flow.
3. Turn switch to AUTO position.
4. Compressor will build to maximum
pressure and shut off.
5. With hose attached to outlet of
compressor, attach tire chuck or
other tool to open end of hose.
6. Adjust regulator to proper pressure
for tool or tire. Operate tool per
instructions.
As air is depleted from the tank by use
of a tire chuck, tool, etc., the compressor
will restart automatically at its preset
"cut-in" pressure. When a tool is being
used continuously, the compressor will
cycle on and off automatically.
7. Turn switch to OFF position, unplug
power cord and drain tank of air
when finished using compressor.
MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form into droplets as it comes from an air
compressor pump. When humidity is high or when a compressor is in continuous
use for an extended period of time, this moisture will collect in the tank. When
using a paint spray or sandblast gun, this water will be carried from the tank
through the hose, and out of the gun as droplets mixed with the spray material.
IMPORTANT: This condensation will cause water spots in a paint job, especially
when spraying other than water based paints. If sand-blasting, it will cause the
sand to cake and clog the gun, rendering it ineffective. A filter in the air line,
located as near to the gun as possible, will help eliminate this moisture.
Model 6ZC63, disposable in-line dessicant dryer designed to hang on user's belt,
and available from Dayton Electric Mfg. Co., is the best answer to this moisture
problem.
Maintenance
Disconnect, tag and lock out
power source then release
all pressure from the system
before attempting to install, service,
relocate or perform any maintenance.
Check compressor often for any visible
problems and follow maintenance
procedures each time compressor is used.
ASME SAFETY VALVE
Do not remove or
attempt to adjust
the safety valve!
Figure 4
Check the safety valve by performing
the following steps:
1. Plug the compressor in and run until
shut off pressure is reached (see
Operating Procedure).
2. Wearing safety glasses, pull the
ring on the safety valve to release
pressure from compressor tank. Use
5
your other hand to deflect fast-
moving air from being directed
toward your face.
3. The safety valve should automatically
close at approximately 40 psi - 50 psi.
If the safety valve does not allow
air to be released when you pull
on the ring, or if it does not close
automatically, it MUST be replaced.
Safety valve must
be replaced if it
cannot be actuated or it leaks air after
ring is released.
A large amount of
fast moving air will
be released when the safety valve is
opened with pressure in the tank. Wear
ANSI approved Z87.1 safety glasses.
DRAIN TANK
Drain moisture from tank by opening
drain valve underneath tank. Tilt tank to
remove all moisture.
