INTRODUCTION
The Model PW4000A- GunJet is a high-pressure spray gun that offers exceptional
operator control, even at maximum flow and pressure conditions. A bottom pivot
trigger reduces operator fatigue by making trigger pull easier. The shut-off valve is
located in the base of the handle, concentrating heat away from the operator’s hand
and slowing heat build-up. A special trigger lock feature locks in the “off” position to
prevent accidental discharge and retracts flush into the handle when the gun is in use.
The Model PW4000AW- incorporates a continuous “Weep” feature to minimize the
chance of freezing and, with the exception of the valve seat sub-assembly, the
PW4000A- and PW4000AW- GunJet spray guns are identical and require the same
installation and operating procedures. The Model PW4000A- and PW4000AW-
GunJet spray guns with the “S” option have a built-in swivel to reduce operator
fatigue and prolong hose life.
