GROUNDING INSTRUCTIONS
This product must be grounded. If it should malfunction
or break down, grounding provides a path of least
resistance for electric current to reduce the risk of electric
shock. This equipment is equipped with a cord having an
equipment–grounding conductor and a grounding plug.
The plug must be plugged into an appropriate outlet that
is properly installed and grounded in accordance with all
local codes and ordinances.
DANGER
Improper connection of the
grounding conductor can result in the risk of
electrocution. Check with a qualified electrician or
service person if you are in doubt as to whether
the outlet is properly grounded.
equipment–
GROUND FAULT CIRCUIT INTERRUPTER PROTECTION
To comply with the National Electrical Code (NFP A 70)
and to provide additional protection from the risk of
electric shock, connect this pressure washer to a circuit
that is protected by a ground–fault circuit–interrupter
(GFCI).
EQUIPMENT MISUSE HAZARD
General Safety
System Pressure
Any misuse of the pressure washer or accessories, such
as overpressurizing, modifying parts, using incompatible
chemicals and fluids, or using worn or damaged parts,
can cause them to rupture and result in fluid injection,
splashing in the eyes or on the skin, or other serious
bodily injury, fire, explosion or property damage.
This sprayer can develop high operating pressure. Be
sure that all spray equipment and accessories are rated
to withstand the maximum working pressure of
sprayer. DO NOT exceed the maximum working
pressure of any component or accessory used in the
system.
this
NEVER alter or modify any part of this equipment; doing
so could cause it to malfunction.
Chemical Compatibility
CHECK all spray equipment regularly and repair or
BE SURE that all chemicals used in the chemical injector
are compatible with the wetted parts of the hose, gun,
wand and tip, as given in the Technical Data (inside back
replace worn or damaged parts immediately
.
ALWAYS wear protective eyewear and appropriate
clothing. If using a chemical injector, read and follow the
cover). Always read the chemical manufacturer
literature before using any chemical in this pressure
washer.

HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If
the hose develops a leak, split or rupture due to any kind
of wear, damage or misuse, the high pressure spray
emitted from it can cause a fluid injection injury or other
serious bodily injury or property damage.
NEVER use a damaged hose. Before each use, check
entire hose for cuts, leaks, abrasion, bulging cover , or
damage or movement of the hose couplings. If any of
these conditions exist, replace the hose immediately DO
.
NOT try to recouple high pressure hose or mend it with
tape or any other device. A repaired hose cannot contain
the high pressure fluid.
ALL FLUID HOSES MUST HA VE STRAIN RELIEFS
ON BOTH ENDS. The strain reliefs help protect the hose
from kinks or bends at or close to the coupling, which can
result in hose rupture.
HANDLE AND ROUTE HOSES CAREFULL Y. Do not
pull on hoses to move the pressure washer. Do not use
chemicals which are not compatible with the inner tube
and cover of the hose. DO NOT expose Graco hose to
TIGHTEN all fluid connections securely before each use.
High pressure fluid can dislodge a loose coupling or allow
high pressure spray to be emitted from the coupling.

Check for Shipping Damage
Check the unit for any damage that may have occurred in
shipping. Notify the carrier immediately if there is any
damage.
Connect to Water Supply
CAUTION
Set Up
Before connecting the unit, be sure the electrical service
matches the specification in Technical Data (inside back
cover) and the voltage label on the unit. With the unit off,
connect the power supply cord to a grounded,
GFCI–protected circuit.
Before attaching to the water supply, check your
local plumbing code regarding cross–connection
to the water supply

A
backflow preventer P/N 801–133 is available to
prevent backflow of contaminated water into the

If you are using a downstream chemical injector, install it
between the pump unloader and the high pressure hose.
Connect the high pressure hose between the pump outlet
and the gun inlet.

DO NOT run the pump dry, which will quickly
damage the pump. Be sure the water supply is
fully turned on before starting the pump.
3. Trigger the gun until water sprays from the tip
indicating that the air is purged from the system.
DO NOT pump caustic materials; such
materials may corrode the pump components.
4. Start the unit.
5. ALWAYS engage the gun’ s trigger safety latch
whenever you stop spraying, even for a moment to
reduce the risk of fluid injection or splashing in the
eyes or on the skin if the gun is bumped or triggered
accidentally.

NOTE: Plunger repair kit, P/N 803–677 is available to
replace retainers, o–rings, washers and
backup rings for three cylinders.
follow the
Pressure Relief Procedure
Warning before proceeding.
1. Loosen the plunger retaining screw five to six turns,
using an M10 wrench. Push the plunger towards the
crankcase to separate the plunger and retaining
screw.
NOTE: The following metric wrenches are needed:
M10, M13 and M30. Repair kits are available.
Refer to the individual repair sections and the
pump parts page for more details. For the best
results, use all parts in the kits.
2. Remove the screw from the plunger and examine the
o–ring, backup ring and copper bearing/gasket
washer. Replace these parts, if necessary, using kit
801–474.
NOTE: There are two dif ferent tool kits to aid in
servicing the pump. P/N 800–298 is used to
ease installation of packings. P/N 800–271
includes the items in 800–298 and tools to aid in
the removal of packing retainers.
3. Remove the plunger and flinger from the plunger
shaft. Clean, examine and replace parts as
necessary.
4. Inspect the plunger shaft for oil leakage from the
crankcase. If leaking is obvious, replace the oil seals.
Otherwise, DO NOT remove these seals as they
cannot be reused. An oil seal kit is available to
replace the seals.
Valves
NOTE: For a set of six valves, order P/N 803–664 or
803–666.
5. Lightly grease the oil seal, if it is being replaced, and
the flinger and replace them on the plunger shaft.
1. Remove the hex plug from the manifold using an
M30 wrench.
Then install the plunger
.
6. Lightly grease the retaining screw and the outer end
of the plunger. Place the washer, o–ring and backup
ring around the screw and install the screw through
the plunger. Torque to 14.4 ft–lb (19.5 Nm).
2. Examine the o–ring under the hex plug and replace it
if it is cut or distorted.
3. Remove the valve assembly from the cavity; the
assembly may come apart.
NOTE: If you plan to replace the packings, refer to
Servicing the V–Packings.
4. Install the new valve. Install the o–ring and hex plug;
torque to 75 ft–lb (103 Nm).
7. Lubricate the outside of each plunger . Slide the
manifold onto the crankcase, being careful not to
damage the seals.
NOTE: Retorque the plug after 5 hours of operation.
8. Install the capscrews and washers
finger–tight.
Pumping Section
Torque the screws to 21.7 ft–lb (29 Nm) following the
tightening pattern (Figure 4). Uneven tightening may
cause the manifold to bind or jam.
1. Remove the eight capscrews and lockwashers from
the manifold using an M13 wrench.
2. Carefully separate the manifold from the crankcase.
NOTE: It may be necessary to tap the manifold lightly

5. Thoroughly clean the packing cavities and examine
for debris and damage.
Servicing the V–Packings
NOTE: There are two types of packing kits: one is
packings only, the other includes the packings,
rings and retainers.
6. Lightly grease the packing cavities and then replace
the packings in the following order: head ring,
v–packing, intermediate ring, head ring, v–packing
and packing retainer with the o–ring installed in the
retainer groove.
1. Remove the manifold as outlined in the Pumping
Section.
2. Carefully pull the packing retainer from the manifold.
Examine the o–ring and replace it if it is cut or
damaged.
CAUTION
Install the parts in the proper order and facing
the correct direction. Improperly installed parts
will cause a malfunction.
3. Remove the v–packing and head ring. Pull out the
intermediate retainer ring. Remove the second
v–packing and second head ring.
7. Reassemble the manifold as instructed in Servicing
the Plungers.
4. Inspect all parts and replace as necessary
