WARNING
If you supply your own hoses and spray gun, be
sure the hoses are electrically conductive, that the
gun has a tip guard, and that each part is rated for
at least

2750 psi (195 bar) Working Pressure

. This
is to reduce the risk of serious injury caused by
static sparking, fluid injection or over-pressurization
and rupture of the hose or gun.
CAUTION
T
o avoid damaging the pressure control, which
may result in poor equipment performance and
component damage, follow these precautions:
1.
Always use a nylon spray hose at least 50 ft.
(15 m) long.
2.
Never use a wire braid hose as it is too rigid to
act as a pulsation dampener
.
3.
Never install any shutof
f device between the
filter and the hose.

See Fig. 2.
1. Connect the hose (74) and gun (67)
and screw it
