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  
sprayer. DO NOT exceed the maximum working  
this  
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  
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  
CHECK all spray equipment regularly and repair or  
replace worn or damaged parts immediately  
.
cover). Always read the chemical manufacturer  
literature before using any chemical in this pressure  
washer.  
’s  
ALWAYS wear protective eyewear and appropriate  
clothing. If using a chemical injector, read and follow the  
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  
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  
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.  
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.

MOVING PARTS HAZARD  
Moving parts can pinch or amputate fingers or other body  
parts. KEEP CLEAR of moving parts when starting or  
NEVER operate the pressure washer without all guards  
and interlocks installed and functioning. Follow the

Technical Data, inside back cover).  
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 (800–412 &  
800–413 only).  
Connect to Air Supply  
Be sure that the air supply has a minimum flow rate equal  
to the air consumption of the motor and that the pressure  
is less than the maximum allowed (see Technical Data,  
inside back cover).

CAUTION  
DO NOT run the pump dry , which will quickly

DO NOT pump caustic materials; such materials  
may corrode the pump components.  
OPERATION  
Two factors control the flowrate and spray pressure of  
Graco air–powered pressure washers: the orifice size of  
the spray tip and the air inlet pressure. Adjust these  
factors to get the desired flowrate and spray pressure,  
Changing Spray Tips). This causes a drop in pressure  
that actuates the chemical injector. Changing back to a  
small diameter spray tip deactivates the chemical injector  
and produces high pressure for rinsing. The flow rate of  
the chemical may be regulated by turning the chemical  
adjustment knob on the injector. Maximum chemical flow  
is at a full two turns counterclockwise from the closed  
(clockwise) position.  
but never allow the pump to exceed 60 cpm. T increase  
o
the flowrate, increase the spray tip orifice or the air inlet  
pressure. Both factors will increase the pump speed, but  
the larger tip orifice will reduce the spray pressure. T o  
increase the spray pressure, increase the air inlet  
pressure.  
Cleaning  
No more than 100 feet (30 m) of spray hose may be used  
between the chemical injector and the spray gun when  
Adjustable Nozzle (800–412 & 800–413)  
the operator is at the same level as the chemical injector  
.
Insert the chemical filter (attached with the clear tubing to  
the chemical injector) into the container of chemical. Turn  
the control ring on the adjustable nozzle clockwise. This  
causes a drop in pressure that actuates the chemical  
injector. Closing the adjustable nozzle deactivates the  
chemical injector and produces high pressure for rinsing.  
The flow rate of the chemical may be regulated by turning  
the chemical adjustment knob on the injector. Maximum  
chemical flow is at a full two turns counterclockwise from  
the closed (clockwise) position.  
If the operator is over 25 feet above the chemical injector  
,
no more than 50 feet (15 m) may be used.  
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 wood, hold the  
nozzle about 3 ft (1 m) from the surface and gradually  
bring it closer, checking to see if the high pressure spray  
is damaging the surface.  
Mist wet the surface with cleaning solution, moving from  
bottom to top. Let it soak briefly , then use the high  
pressure rinse to “chisel” off the soil, moving from top to  
bottom. Keep the nozzle angled to the surface and at a  
distance determined to be best for the surface. If some  
soil remains, repeat the procedure, letting the chemical

WARNING  
Installing and Changing Spray Tips  
(800–295 only)  
WARNING  
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.  
,
To reduce the risk of serious bodily injury including  
,
fluid injection or splashing in the eyes or onto the  
skin, use extreme caution when changing spray  
tips. If a spray tip clogs while spraying, engage the  
gun safety latch immediately  
.
ALWAYS follow the  
procedure below  
.
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.  
1. Follow the Pressure Relief Procedure  
.
2. Point the gun and wand away from yourself and  
anyone else.  
3. Without holding your hand over the spray tip (A), pull  
back the quick coupler ring (B). Remove the old tip  
and install a new one, and then release the ring. See  
Figure 3.  
4. Be sure the tip is secure before starting to spray  
again.  
5. Tip holding holes are provided on the chassis.  
CAUTION  
To avoid blowing the o–ring out of the  
coupler, due to the high pressure in the system,  
never operate the pressure washer without a tip

SHUTDOWN, FLUSHING AND STORAGE  
1. If the pressure washer will be exposed to freezing  
temperatures, drain all water out of the pump. If it  
must be stored in freezing temperatures, flush the  
unit with a 50% anti–freeze solution. Relieve  
pressure. Flush the pressure washer before using it  
again to remove the anti–freeze.  
WARNING  
Pressure Relief Procedure  
To reduce the risk of serious bodily injury  
,
including fluid injection and splashing in the eyes,  
or on the skin, always follow this procedure  
whenever you stop spraying for more than 10  
minutes, when shutting down, and before  
checking or repairing any part of the system.  
CAUTION  
1. Engage the trigger safety latch.  
2. Turn the air supply off.  
If water does freeze in the pressure washer, thaw  
it in a warm room before trying to start it. DO NOT  
pour hot water on or into the pump!  
3. Disconnect the air supply  
.
4. Shut off the water supply  
.
5. Disengage the trigger safety latch and trigger  
the gun to relieve pressure, and then engage  
the trigger safety latch again.  
2. After each use, wipe all surfaces of the pressure  
washer with a clean, damp cloth.
