Setup
1. Prepare the paint according to the manufactur-
er’s
recommendations.
This is probably the most important step
toward trouble-free spraying!
Remove any skin that may have formed on the top
of the paint. If necessary
, thin the paint. Finally
,
strain the paint through a fine nylon mesh bag
(available at most paint dealers) to remove par
-
ticles that could clog the spray tip.
2. Install a spray tip and RAC IV tip guard on the
spray
gun as instructed in manual 307–848.
3. Connect
the hose and gun.
Connect the other end
of
the hose to the sprayer
.
4.
Check the hydraulic oil level.
Unscrew the fill cap
(5).
The oil should be 1 inch (25 mm) from the top of
the
plate. If
the oil is low
, fill as necessary with light
-
weight hydraulic oil; use only Graco Hydraulic Oil,
Part
No. 218–797. Install the fill cap. See Fig. 1.
5. Check the electrical service which must be 120V,
60
HzAc, 15 Amp (minimum). Be sure the electrical
outlet is properly grounded.
Y
ou can use up to 100 foot (30 m) of 3 wire, 14
gauge (minimum) extension cord. Longer exten
-
sion cords may af
fect the sprayer performance.
Use more spray hose, not longer extension cords.
Do not remove the third (grounding) prong of the
plug, and do not use an adapter
.
6. Plug in the sprayer. First be sure the ON/OFF
switch (11) is OFF and the pressure control (4) is
turned
fully
counterclockwise
. Plug the sprayer into
a
grounded outlet that is at least 20 foot (6 m) away
from
the spray area to reduce the chance of a spark
igniting
spray vapors or dust particles.
