HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read and understand all instruction manuals beforeoperating equipment.
FLUID INJECTION HAZARD
General Safety
mis pressure washer generates very high fluid
pressure. Spray from the gun, leaks or ruptured
components can inject fluid through
your skin and into
your body and cause extremely seriousbodily injury
including the need for amputation. Also,fluid
injectedor
splashed into the eyes or on skin
the can cause serious
damage.
Pressure Relief Procedure
To reduce the risk of serious
bodily injury, includingfluid
injection and splashing in the eyesor on the skin,
always follow this procedure whenever you stop
10 minutes, when shutting down,

safety latch again.
Be sure equipment safety devices are operating
properly before each
use.
6. Before long-term (overnight) storage, disconnect
the water supply and disconnect the electricity.
Medical Treatment
If any fluid appears to penetrate your skin, get
EMERGENCY MEDICALTREATMENTATONCE.DO
NOT TREATAS A SIMPLE CUT. Tell thedoctor exactly
what fluid was injected.
Spray Gun Safety Devices
Be sure all gun safety devices are operating properly
before each use.Do not remove ormodify any part of
the gun; this can cause a malfunction and result in
serious bodily injury.
NOTE TO PHYSICIAN lnjectionin the skinis a
traumatic injur,! It Is Important to treat the injury
surglcaily as soon as possible. Do not delay
treatment to research toxicity Toxicity
is a
concern with some exotic coatings injected
direct& into the bloodstream. Consultationwith a
hand surgeon
plastic surgeon or reconstructive
may be advisable.
SAFETY LATCH: Whenever you stop spraying for a
moment, always set the gun Safety latch
in the engaged
or "safe"position, making the gun inoperative. Failureto
properly set the safety latch can resultin accidental
triggering of the gun.
SPRAY TIP SAFEPI: Use extreme caution when
cleaning or changing spray tips. If a spray tip clogs
while spraying, engage the gun safety latch
immediately. ALWAYS follow the Pressure Rellet
Procedure and then remove the spray tip
to clean it.
GROUNDING INSTRUCTIONS
mi s Droduct mustbe grounded. Ifit should malfunction or bieak down, grounding provides a path of least
resistance for electric current to reduce the risk of
electric shock. This equipment
is equipped witha cord
having an equipment-grounding conductor and a
grounding plug. The plug must be plugged into an
aooromiate outlet that is DroDerlv installed and
giunded in accordance with ail lbcal codes and
ordinances.
1
DANGER
improper connectionof the equipment- grounding
conductor can resultIn the risk of electrocution.
Check with a qualified electrician or service
person if you are in doubtas to whether the outlet
Is properly grounded.
GROUND FAULT CIRCUIT INTERRUPTER PROTECTION
To comply with the National Electrical Code
(NFPA 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-fauit circuit-intempter
(GFCI).
EQUIPMENT MISUSEHAZARD
General Safety
Any misuse of the pressure washer or accessories,
such as overpressurizing, modifying parts, using
incompatible chemicals and fluids,
or using wom or
to rupture andresun in
damaged parts, can cause them
fluid injection, splashing in the eyes
or on the skin, or
other serious bodily injury, fire, explosion or property
damage.
NEVER alter or modify any part ofthis equipment;doing
so could cause it to malfunction.
CHECK ail spray equipment regularly and repair or
replace wom or damaged parts immediately.
ALWAYS wear protective eyewear and appropriate
clothing. If using a chemical injector, read andfollow
the
chemical manufacturer’s literature for
recommendations on additional protective equipment,
such as a respirator,
System Pressure
This sprayer can develophigh operating pressure. Be
sure thatall 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.
Chemical Compatibility
BE SURE that ail chemicals used in the chemical
injector are compatible with the wetted parts of the
hose, gun, wand andtip, as givenin the Technical Data
(inside back cover). Always
read the chemical
manufacturer’s literature beforeusing any chemical in
this pressure washer.

HOSE SAFETY
High pressure fluid
in the hoses can
be very dangerous.
If the hose developsa leak, splitor rupture due to any
kind of wear, damage or misuse, the high pressure
spray emittedfrom it can causea fluid injectioninjury or
other serious bodily injury or property damage.
ALL FLUID HOSESMUST HAVE STRAlN RELIEFSON
BOTH ENDS. The strain reliefs help protect the hose
from kinks or bends at or close to the coupling, which
can resultin hose rupture.
TlGHTEN all fluid connections securely before each
use. High pressure fluid can dislodge
a loose coupling
or ailow high pressure spray to be emitted from the
coupling.
N N E R use a damaged hose. Before each use,'check
entire hosefor cuts, leaks, abrasion,bulging cwer, or
damage or movement of the hosecouplings. 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.
HANDLEAND ROUTE HOS€S W F F U L L 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 ofthe hose. DO NOT expose Graco hoseto
