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.

may result in poor equipment performance and
component damage, follow these precautions:
1.

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.
