Always use Genuine Graco Parts and Accessories,
available from your Graco distributor.
Grounding
•
Pump: Use a ground wire and clamp. See separate
system manual.
•
Hydraulic, and fluid hoses: Use only electrically
conductive hoses.
•
Hydraulic power supply: Follow manufacturer's
recommendations.
•
Spray gun: Ground through connection to a prop-
erly grounded fluid hose and pump.
•
Fluid supply container: Follow your local code.
•
Object being sprayed: Follow your local code.
•
Solvent pails used when flushing: Follow your
local code. Use only metal pails, which are conduc-
tive, placed on a grounded surface. Do not place the
pail on a nonconductive surface, such as paper or
cardboard, which interrupts the grounding continu-
ity.
•
To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the spray
gun firmly to the side of a grounded metal pail, then
trigger the gun.

Startup
Before each use, check the hydraulic fluid level and add
fluid as necessary to fill the lines.
FIRE AND EXPLOSION HAZARD
If hydraulic oil becomes too hot, it can reach its flash
point and cause a fire. Operating at too high an oil tem-
perature can also cause faster motor seal wear and
leakage. The recommended hydraulic oil operating
temperature is 80 to 115° F (27 to 45° C). If the oil tem-
perature approaches 130° F (54° C), shut off the motor
and check the hydraulic oil supply cooling system, fil-
ters, etc. Clean or repair as needed.
Always use Graco-approved Hydraulic Oil or equivalent
(see Accessories). Do not substitute a lower grade oil
or one with a lower flash point.
The equivalent is a premium, ISO grade 46
petroleum-based hydraulic oil containing rust and oxi-
dation inhibitors and anti-wear agents. Before using
any other type of oil in this equipment, call your Graco
distributor. Unauthorized use of lesser grade oil or sub-
stitutes will void the warranty.
