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 by component ruptures, all
accessories added to the reciprocator power supply
side of the pump fluid outlet side must have at least a
1500 psi (10 MPa, 103 bar) maximum working
pressure.
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.
Pump: Use a ground wire and clamp. Remove the
ground screw (Z) and insert through the eye of the ring
terminal at end of ground wire (Y). Fasten the ground
screw back onto the pump and tighten securely. Con-
nect the other end of the ground wire to a true earth
Pump Accessories
Suction Tube Kit: A suction tube kit is available for
siphoning from 55 gallon containers.
Intake Tube: To install, apply PTFE tape to the female
threads at the top of the tube (Q). Screw the tube tightly
into the intake housing of the stubby pump.
Low-Level Cutoff Valve: To install, screw the low-level
cutoff valve into the bottom of the pump intake tube or
the suction tube. This valve closes the pump intake
when the fluid level is low, causing the pump to stall to
avoid running all day.

Hydraulic and fluid hoses: Use only electrically con-
ductive hoses.
Hydraulic power supply: Follow manufacturer’s recom-
mendations.
Pump Outlet Drain Valve: Install a drain valve (D) close
to the pump fluid outlet assist in relieving fluid pressure
in the pump, hose, and dispense valve when the pump
is shut off.

Pressure Regulation: The hydraulic fluid control reduces
the hydraulic oil pressure to the operating pressure
required for the application.
Flow Regulation: The hydraulic fluid control limits the
maximum amount of oil flow to the motor to keep the
hydraulic motor within the cycle rate limit. This prevents
pump runaway. The limit on the Power-Star is 66 cpm.

Operation
Operation
Pressure Relief Procedure
Before Starting the Pump
Follow the Pressure Relief Procedure whenever
you see this symbol.
Recommended Hydraulic Oil
Use a Graco-approved Hydraulic Oil or a premium, ISO
grade 46 petroleum-based hydraulic oil containing rust
and oxidation inhibitors and anti-wear agents.
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.
Before using any other type of oil in this motor contact
your Graco distributor. Unauthorized use of lesser grad
oil or substitutes may void the warranty.
1. Close the supply line shutoff valve, and then the
return line shutoff valve.
1. Check the hydraulic fluid level in the hydraulic power
supply before each use, and add fluid as necessary
to fill the lines.
2. Open the dispensing valve to relieve the pressure.
2. Flush the pump before using it for the first time to
remove the light oil that was left in after factory test-
ing to protect the pump from corrosion. Be sure the
solvent used is compatible with the fluid to be
pumped and the pump’s wetted parts. See Techni-
from the outlet hose.
3. Place a container under the drain valve to catch any
drainage. Open the pump outlet drain valve.
4. Leave the drain valve open until you are ready to
dispense again.
NOTE: If you suspect that the dispensing valve, exten-
sion, or grease fitting coupler is clogged, or that the
pressure has not been fully relieved after following the
steps above, VERY SLOWLY loosen the coupler or
hose end coupling and relieve pressure gradually, then
loosen completely and clear the clog.
To Start the Pump
1. Turn on the hydraulic power supply.
2. Open the return line shutoff valve (H) first, and
slowly open the hydraulic supply line shutoff valve
3. Adjust the hydraulic inlet pressure from 500 to 1500
psi (3.5 to 10.3 MPa, 35 to 103 bar) with the regula-
tor control adjustment (M) on the hydraulic fluid con-
trol (A). Increasing the inlet pressure increases the
outlet pressure. Decreasing the inlet pressure
decreases the outlet pressure.
4. Always use the lowest pressure possible to obtain
the desired results. This reduces pump wear.

Operation
5. Never allow a pump to run dry of the fluid being
pumped. A dry pump quickly speeds up and can
damage itself. If it speeds up, shut off the power
supply to the reciprocator immediately. Refill the
supply container and prime the pump to eliminate
air.
NOTE: To prevent the pump from running dry, use a
low-level cutoff valve.
Shutdown and Care
At the end of the work shift or when the pump is unat-
tended, always relieve the pressure, see Pressure Relief
Procedure on page 8.
Emergency Stop Procedure
Close the supply line shutoff valve marked STOP.
