Installation  
Installation  
Grounding  
The equipment must be grounded to reduce the risk  
of static sparking and electric shock. Electric or static  
sparking can cause fumes to ignite or explode.  
Improper grounding can cause electric shock.  
Grounding provides an escape wire for the electric  
current.  
Z V W  
Pump: use ground wire and clamp (supplied). Loosen  
grounding lug locknut (W) and washer (V). Insert one  
2
end of a 12 ga (1.5 mm ) minimum ground wire (Y) into  
Y
the slot in lug (Z) and tighten the locknut securely. Con-  
nect the other end of the wire to a true earth ground.  
Order Part No. 237569 Ground Wire and Clamp.  
Hydraulic Hoses and Fluid Outlet Hoses: use only  
electrically conductive hoses.  
FIG. 1  
Hydraulic Power Supply and Air Compressor: follow  
manufacturer’s recommendations.  
Any pails used when flushing: use only metal  
grounded pails when flushing. Make firm metal-to-metal  
contact between a metal part of the dispense valve and  
the pail. Use the lowest possible pressure.

Pressure Regulation: The hydraulic fluid control pres-  
sure reducing valve (J) reduces the hydraulic oil pres-  
sure to the operating pressure required for application.  
Flow Regulation: The hydraulic fluid control valve (K)  
limits the maximum amount of oil flow to the motor to  
keep the hydraulic motor within the recommended cycle  
rate limit. This prevents pump runaway. The limit on the  
K
L
Dyna-Star is 60 cpm. The limit on the Power-Star is  
66 cpm.  
Pump Isolation: The hydraulic fluid control (A and B) has  
ball valves on the supply and return sides of the mani-  
fold. The ball valves isolate the hydraulic fluid control  
and pump for servicing without stopping the hydraulic  
power source.  
Hydraulic Fluid Control: The hydraulic fluid control pro-  
vides pressure regulation, flow regulation, and pump  
isolation. See the Typical Installation as a guide. For  
assistance in designing a system to suit your needs,  
contact your Graco Representative.

Installation Notes  
Hydraulic Components  
NOTICE  
The hydraulic supply system must be kept clean at all  
times to reduce the risk of damaging the reciprocator  
hydraulic power supply.  
• Always turn off the supply side valve (G) to avoid  
possible serious injury or component damage.  
See the Typical Installation on page 5.  
Blow out all hydraulic lines with air, flush thoroughly  
with solvent, and then blow out the air again before  
connecting the lines to the reciprocator.  
Maximum Working Pressure of Accessories  
To reduce the risk of serious injury including fluid  
injection and splashing in the eyes or on the skin,  
which may be caused if a component ruptures, all  
accessories added to the reciprocator power  
supply side must have at least 1500 psi (10.5  
MPa, 105 bar) maximum working pressure and  
those to the pump fluid outlet side must have at  
least a 375 psi (2.6 MPa, 26 bar) maximum  
Hydraulic Power Supply  
To reduce the risk of over pressurizing the hydraulic  
reciprocator, which could cause a rupture and  
serious injury, including fluid injection, the hydraulic  
power must have a means to limit the incoming fluid  
flow to the reciprocator to a maximum of 3 gpm (11  
liter/min) at 1500 psi (10.5 MPa, 105 bar) for the  
working pressure for Dyna-Star and 1500 psi  
(10.5 MPa, 105 bar) for the Power-Star .  
Do not kink hoses. Adjust swivel connections if nec-  
essary.  
Always use permanently coupled electrically con-  
ductive hoses.  
Dyna-Star and 10 gpm (37 liter/min) at 1500 psi  
(10.5 MPa, 105 bar) for the Power-Star .  
Refer to the application data from Graco to make  
determinations as to the location and height to  
mount the control.  
Recommended Hydraulic Oil  
Use Graco approved Hydraulic Oil or 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 control,  
contact your Graco distributor. Unauthorized use of  
lesser grade oil or substitutes may void the warranty.  
See Technical Data on page 12 for hydraulic oil  
working temperatures.

Pressure Relief Procedure  
Hydraulic Fluid Level Check  
Follow the Pressure Relief Procedure whenever  
you see this symbol.  
Check the hydraulic fluid level in the hydraulic power  
supply before each use, and add fluid as necessary to  
fill the lines.  
This equipment stays pressurized until pressure is  
manually relieved. To help prevent serious injury from  
pressurized fluid, such as skin injection, splashing  
fluid and moving parts, follow the Pressure Relief  
Procedure when you stop spraying and before  
cleaning, checking, or servicing the equipment.  
Starting the Pump  
Never exceed 1500 psi (10.5 MPa, 105 bar) Maxi-  
mum Hydraulic Pressure to the control.

with a 1:1 Power-Star pump.  
Be sure all accessories added to the reciprocator  
power supply side of the control are capable of at  
least 1500 psi (10.5 MPa, 105 bar) maximum work-  
ing pressure and all of those for the pump fluid out-  
let side of the control have at least 375 psi (2.6 MPa,  
If you suspect that the dispensing valve nozzle or hose  
is completely clogged, or that pressure has not been  
fully relieved after following the steps above, VERY  
SLOWLY loosen the hose end coupling and relieve pres-  
sure gradually then loosen completely, now clear the  
obstruction.  
26 bar) maximum working pressure for Dyna-Star  
and 1500 psi (10.5 MPa, 105 bar) for Power-Star .  
1. Turn on hydraulic power supply.  
Emergency Stop Procedure  
2. Open the return line shutoff valve (E) first and slowly  
open the hydraulic supply shutoff valve (G).  
Close the red-marked supply line shutoff valve marked  
STOP.  
3. Remove the cap on the pressure reducing valve to  
reveal the cap screw adjustment.  
Before Starting the Pump  
4. Adjust the hydraulic inlet pressure from 50 to 1500  
psi (0.3 to 10.5 MPa, 3 to 105 bar) with an allen  
wrench inserted in the regulator pressure control  
adjustment on the pressure reducing valve (J).  
Increasing the inlet pressure (clockwise) increases  
the pump outlet pressure. Decreasing the inlet pres-  
sure (counter clockwise) decreases the pump outlet  
pressure.  
When starting up the hydraulic system, open the return  
line shutoff valve (E) first.  
5. Always use the lowest pressure possible to obtain  
the desired results. This reduces pump wear.
