Installation
Grounding
To reduce the risk of static sparking, ground the pump,
object being sprayed , and all spray/dispensing equip-
ment used or located in the spray/dispensing area.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment. Be
sure to ground all of this spray/dispensing equipment.
1. Pump: loosen the grounding lug locknut (W) and
washer (X). Insert one end of a 1.5 mm2 (12 ga)
minimum ground wire (Y) into the slot in lug (Z)
and tighten the locknut securely. See Fig. 1. Con-
nect the other end of the wire to a true earth
ground. Order Part No. 237569 Ground Wire and
Clamp.

2. Hydraulic hoses: use only electrically conductive
hoses.
3. Fluid hoses: use only electrically conductive fluid
hoses.
4. Hydraulic power supply: follow manufacturer’s
recommendations.
5. Spray gun/dispensing valve: grounding is obtained
through connection to a properly grounded fluid
hose and pump.
6. Fluid supply container: according to your local
code.
7. Object being sprayed: according to your local
code.
8. All solvent pails used when flushing, according to
your local code. Use only metal pails, which are
conductive, placed on a grounded surface. Do not
place the pail on a nonconductive surface, such as
paper or cardboard, which interrupts the grounding
continuity.
9. To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
spray gun/dispensing valve firmly to the side of a
grounded metal pail, then trigger the gun/valve.

CAUTION
Keep the hydraulic system clean
To reduce the risk of damaging the hydraulic power
supply, blow out all hydraulic lines with air, flush
thoroughly with solvent, and then blow out with air
again before connecting the lines to the reciprocator.
Always plug the hydraulic inlets, outlets and lines
when disconnecting them to avoid introducing dirt
and other contaminants into the system.
Carefully follow the manufacturer’s recommendations
on reservoir and filter cleaning, and periodic changes
of hydraulic fluid.
CAUTION
Recommended Hydraulic Oil
Use Graco-approved Hydraulic Oil or the equivalent.
Order Part No. 169236 5 gallon (20 liter) or 207428 1
gallon (3.8 liter). The equivalent is a premium, ISO
grade 46 petroleum-based hydraulic oil containing
rust and oxidation inhibitors and anti–wear agents.
Before using any other type of oil in this Graco
reciprocator, contact your Graco distributor. Un-
authorized use of lesser grade oil or substitutes may
void the warranty.
The Typical Installation shown in Fig. 2 is only repre-
sentative. Contact your Graco distributor for specific
information. Pump dimensions and mounting hole
layout are shown on page 14.
Hydraulic Power Supply
Be sure that the hydraulic power supply is equipped
with a suction filter to the hydraulic pump and a system
return line filter of 10 micron size. Carefully follow the
manufacturer’s recommendations on reservoir and
filter cleaning, and periodic changes of hydraulic fluid.
