Tighten Fasteners
Before mounting and using the pump for the first time,
check and retorque all external fasteners. Follow
Torque Instructions, page 14, or see the torque tag on
your pump. After the first day of operation retorque the
fasteners.
Mount the Pump
1. Verify that the bolts holding the pump feet to the
brackets are tight. Torque to 40-45 ft-lb (54-61 N•m)
for Polypropylene and Stainless Steel, and 55-60
ft-lb (75-81 N•m) for Aluminum.
2. Secure the brackets to the floor. Do not mount on
any other surface. The pump must be mounted
upright.
3. Make sure the surface is flat and that the pump does
not wobble.
4. For ease of operation and service, mount the pump
so air valve, air inlet, fluid inlet, and fluid outlet ports
are easily accessible.
Ground the System
Pump: See FIG. 3. Loosen the ground screw (N). Insert
one end of a 12 ga. minimum ground wire behind the
ground screw and tighten the screw securely. Connect
the clamp end of the ground wire to a true earth ground.
A ground wire and clamp, Part 238909, is available from
Graco.
Air and fluid hoses: Use only grounded hoses with a
maximum of 500 ft (150 m) combined hose length to
ensure grounding continuity.
Air compressor: Follow manufacturer’s
recommendations.
Fluid supply container: Follow local code.
To avoid serious injury or death from toxic fluid or
fumes:
• Ventilate to a remote area. The pump exhaust air
may contain contaminants. See Air Exhaust Ven-
tilation on page 11.
• Never move or lift a pump under pressure. If
dropped, the fluid section may rupture. Always fol-
low the Pressure Relief Procedure on page 12
before moving or lifting the pump.

The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
• Aluminum and stainless steel pumps have a
ground screw. Always ground the entire fluid sys-
tem as described below.
• Polypropylene pumps are not conductive and are
not for use with flammable fluids.
• Follow your local fire codes.
