WARNING
If you are supplying 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 3000 psi (210 bar, 21 MPa) Maxi-
mum 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
To avoid damaging the pressure control, which may
result in poor equipment performance and compo-
nent damage, follow these precautions.
1. Always use nylon spray hose at least 50 ft. (15.2
m) long.
2. Never use a wire braid hose; it is too rigid to act
as a pulsation dampener.
3. Never install any shutoff device between the filter
and the main hose. See Fig 2.
4. Always use the main filter outlet (55) for one gun
operation. Never plug this outlet.
1. Be sure your system is properly grounded.
Read and follow the warning section, FIRE OR
EXPLOSION HAZARD, on page 4. If you are
using the sprayer with the gasoline engine, secure
the ground wire to a true earth ground. If you are
using the sprayer with an electric motor, plug it into
a properly grounded outlet.
