Operating Procedures
Daily Start-Up Procedures
1. Set the Auto-On/Off switch to the Off position.
2. Inspect the air compressor, air hose, and any
accessories/tools being used for damage or obstruction.
If any of these mentioned items are in need of repair/
replacement, contact your local authorized dealer before
use.
3. Close the drain valve.
4. Connect the air hose to the quick connect socket on
the regulator assembly by inserting the quick connect
plug on the air hose into the quick connect socket. The
quick connect socket collar will snap forward and lock
the plug into place providing an air tight seal between
the socket and plug. To release the air hose push the
collar back on the quick connect socket.
5. Plug the power cord into the proper receptacle.
Turn the Auto-On/Off switch to the On-Auto position and
the compressor will start and build air pressure in the
tank to cut-out pressure and then shut off automatically.
Adjust the regulator to a PSI setting that is needed for
your application and be sure it is within the safety
standards required to perform the task. If using a
pneumatic tool, the manufacturer should have
recommendations in the manual for that particular
tool on operating PSI settings.
The air compressor is now ready for use. The following
inflation and cleaning accessories packaged with this
unit should only be operated at maximum pressure
of 90PSI: Blow gun, adapter and inflation needle.
3. Set the outlet pressure to zero on the regulator.
4. Remove any air tools or accessories.
5. Open the drain valve allowing air to bleed from the
tank. After all of the air has bled from the tank, close
the drain valve to prevent debris buildup in the valve.
Drain the tank in a suitable location; condensation will be
present in most cases of draining.
A WARNING
Water that remains in the tank during storage will corrode
and weaken the air tank which could cause the tank to
rupture. To avoid serious injury, be sure to drain the tank
after each use or daily.
