WARNING
FIRE AND EXPLOSION HAZARD
Proper electrical grounding is essential
to reduce the risk of fire or explosion
which can result in serious injury and
property damage. Also read FIRE OR
EXPLOSION HAZARD on page 2.
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 3000 psi (21.0 MPa, 210 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
To avoid damaging the pressure control, which may
result in poor equipment performance and compo-
nent 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 shutoff device between the filter
and the hose. See A, Fig. 2.
1. Connect gun (B) and 50 ft hose (C). Don't install
the spray tip yet. See Fig. 2.
2. Fill wet-cup (D) 1/3 full with Graco Throat Seal
Liquid, supplied.
Setup
3. Check electrical service. Be sure electrical service
is 120 Vac, 60 Hz, 20 A. Use properly grounded
outlet. Do not remove grounding prong of power
supply cord or of any extension cords used. Do not
use an adapter. Extension cords must have 3
wires of minimum 12 gauge size. Long extension
cords reduce sprayer performance. If 20 amp
service is not available, set 15/20 amp switch (C)
to 15 amp to avoid nuisance tripping of circuit
breakers.
4. With switch (E) to OFF, plug power supply cord
into grounded electrical outlet located at least 20 ft
away from spray area.
5. Flush pump before using it. See page 10.
