General Safety
.
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.
System Pressure
This sprayer can develop high operating pressures. Be
sure that all spray equipment and accessories are rated
to withstand the maximum working pressure of
this
sprayer. DO NOT exceed the maximum working
pressure of any component or accessory used in the
system.
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 cover). Always read the chemical manufacturer’s
literature before using any chemical in this pressure
washer.
replace worn or damaged parts immediately
.
ALWAYS wear protective eyewear and appropriate
clothing. If using a chemical injector, read and follow the
chemical manufacturer
’s literature for
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 CAREFULLY. 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.
temperatures above 200_ F (93_ C) or below –40_
F
(–40_ C).
FUEL AND EMISSION HAZARDS
NEVER fill the fuel tank while the unit is running or hot.
The fuel used in this unit is combustible and when spilled
on a hot surface can ignite and cause a fire. ALWAYS fill
tank slowly to avoid spilling.
NEVER alter the throttle setting, which is factory set.
Tampering with this adjustment can damage the
pressure washer and will void the warranty
.
NEVER operate the unit in a closed building. The
exhaust contains carbon monoxide, a poisonous,
odorless, invisible gas which can cause serious injury or
death if inhaled.

Set Up (2340)
Connect to Water Supply
CAUTION
If you are using a downstream chemical injector, install it
between the pump unloader and the high pressure
hose, using the quick couplers provided.
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 fresh water supply .
Install it upstream from the pump.
Connect the high pressure hose between the pump
outlet and the gun inlet. Both of these connections are
made with quick couplers.

If the engine is cold, completely close the engine
choke. Grasp the starter rope, brace one foot on the
pressure washer chassis and pull rope rapidly and
firmly. Continue holding the rope as it returns. Pull
and return the rope until the engine starts. In cool
weather, the choke may have to be kept closed for
10 to 30 seconds before opening it to keep the
engine running. Otherwise, open the choke as soon
as the engine starts.
is started safely and properly
.
1. Check oil levels.
Engine: Add SAE 30 or 10W–30 weight detergent
oil as necessary
.
Pump: Add SAE 20 or 30 weight non–detergent oil
as necessary
.
If the engine is warm, leave the choke open, or just
partly close it. Start the engine as described in the
preceding paragraph. When it starts, be sure to
NOTE: Some units are equipped with a low–oil sensor
that shuts the engine of f if the oil level falls
below a certain level. If the unit stops
unexpectedly, check both the oil and the fuel
levels. Check the oil level each time the unit is
refueled.
open the choke completely
.
CAUTION
On recoil start engines, never let the starter rope
return by itself. It could jam the recoil system.
2. Check fuel level.
7. 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.
WARNING
DO NOT refuel a hot engine. Refueling a hot
engine could cause a fire. Use only fresh, clean
regular or unleaded gasoline. Close the fuel
shutoff valve during refueling.
8. ALWAYS observe the following
CAUTIONS to
avoid costly damage to the pressure washer
.
3. Turn on the water supply
.
CAUTION
CAUTION
DO NOT allow the pressure washer to idle for more
than 10 minutes. Doing so may cause the
recirculating water to overheat and seriously
damage the pump. Turn off the pressure washer if it
will not be spraying or cleaning at least every 10
minutes. If heated inlet water is used, reduce this
time further.
Never run the unit dry. Costly damage to the pump
will result. Always be sure the water supply is
completely turned on before operating.
4. Trigger the gun until water sprays from the tip
indicating that the air is purged from the system.
5. Open the fuel shutoff valve. Be sure the spark plug
ignition cable is pushed firmly onto the spark plug.
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.
On those units equipped with an ignition shutof
f
switch, put the switch in the “on” position and put the
throttle in the “run” position.
DO NOT operate the pressure washer with the inlet
water screen removed. This screen helps keep
abrasive sediment out of the pump, which could
clog or scratch the pump. Keep this screen clean.
6. Start the engine.
NOTE: For easier starting, have one person start the
pressure washer while another person triggers
the spray gun.
DO NOT pump caustic materials; such materials
may corrode the pump components.
9. See the chemical injector or sandblaster kit manual
for detailed cleaning information if these
accessories are used (2340 only).

Chemical Injector
Trigger Safety Latch
WARNING
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 cover). Always read the chemical manufacturer’s
literature before using any chemical in this pressure
washer.
To reduce the risk of serious bodily injury
including fluid injection, splashing in the eyes or
on the skin, ALWAYS engage the trigger safety
latch whenever spraying stops, even for a
moment.
,
WARNING
Observe chemical manufacturer
precautions regarding use of goggles, protective
clothing or respirators.
In the engaged position, the trigger safety latch
prevents the gun from being triggered
accidentally by hand or if it is dropped or bumped.
Be sure the latch is pushed fully down when
engaging it or it cannot prevent the gun from being
triggered. See Figure 2.
’s safety
1026 & 1530: A downstream chemical injector is
provided with the pressure washer. Insert the chemical
strainer (attached with clear tubing to the chemical
injector) into the container of chemical. Push the nozzle
holder on the end of the wand away from the gun. This
causes a drop in pressure that actuates the chemical
injector. Pull the nozzle holder to deactivate the
chemical injector and produce high pressure for rinsing.
The flowrate of the chemical is regulated by turning the
chemical adjuctment knob on the injector . Maximum
chemical flow is at a full two turns counterclockwise from
the closed (clockwise) position. T wisting the nozzle
holder will change the spray fan angle.
2340: The chemical injector is an accessory. See the
chemical injector instruction manual.
TRIGGER SAFETY LATCH SHOWN ENGAGED
WARNING
DO NOT attempt to open or close the adjustable
nozzle when the spray gun is in use. Be sure that
the trigger safety latch on the gun is in the ”ON”
position before adjusting to avoid serious bodily
injury or fluid injection.
Check the distance that you will need to hold the spray
nozzle from the surface by test spraying on a scrap of
similar material. For soft surfaces, such as wook, hold
nozzle 3 ft (1 m) from the surface and gradually bring it
closer, checking to see if the high pressure spray is
damaging the surface.
TRIGGER SAFETY LATCH SHOWN
DISENGAGED
Figure 2
Mist the wet surface with cleaning solution. Let it soak
briefly, then use the high pressure rinse to ”chisel” off the
soil. Keep the nozzle at an angle to the surface and at a
distance determined to be best for the surface. If some
soil remains, repeat the procedure, letting the chemical
soak a little longer . Stubborn soil can be cleaned of f
better with a stronger, heated cleaning solution.
Protect surfaces that might be damaged by the cleaning
solution or the high pressure spray. Rinse the solution
before it dries.
