DeVilbiss HARG-510 Service Manual

SERVICE MANUAL
EN
IMPORTANT: Read and follow all Instructions and Safety
Precautions before installing, operating or maintaining this
equipment. Keep this manual for future reference.
Improper use can cause bodily injury or equipment
damage. Read the following:
• This air regulator and gauge assembly is intended only
for use in general service air systems. Do not use for
liquids or gases other than air.
• Do not use where pressure or temperature can exceed
rated operating conditions (see specifications).
• Regulated outlet pressure must never be set higher
than the maximum operating pressure of the down-
stream air tool or equipment. An outlet pressure gauge
should always be used.
The accuracy of the indication of pressure gauges can
change during shipment and normal use. If gauge
accuracy is necessary for preventing risks of injury or
property damage, the gauge should be checked before
use and on a routine periodic basis. (See ANSI B40-1974
for gauge standards.)

DESCRIPTION

This unit is used in a compressed air system to maintain a nearly
constant outlet pressure despite change in inlet air pressure and
changes in downstream flow requirements. It is also used for
finer control of air at the spray device. The air setting can be
locked in place by pushing the adjusting knob downward.
