Air Line and Accessories
NOTE: Install air line accessories in the order shown in
the Typical Installation.
D Install a pump runaway valve (G) to shut off the air
tp the pump if the pump accelerates beyond the
preadjusted setting. A pump that runs too fast can
be seriously damaged.
D Install an air line lubricator (F) for automatic air
motor lubrication.
D Install a bleed-type master air valve (H) to relieve
air trapped between the valve and the motor when
the valve is closed.
WARNING
Trapped air can cause the air motor to cycle unex-
pectedly, causing serious injury if you are adjusting
or repairing the pump. Be sure to follow the Pres-
sure Relief Procedure on page 12.

D Install the air regulator (C) to control pump speed
and pressure.
D On the main air supply line from the compressor,
install an air line filter (E) to remove harmful dirt and
contaminants from the compressed air supply.
D For Models 240880 through 240886, install the
provided air regulator/safety valve (K) at the pump
air inlet with the nipple (7a, also included).
Avoid hanging air accessories directly on the pump
air inlet. The fittings are not strong enough to sup-
port the accessories and may cause one or more to
break. If accessories must be installed directly on
the pump, provide a bracket on which to mount
them.
