EQUIPMENT MISUSE HAZARD
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.
NEVER alter or modify any part of this equipment;
doing so could cause it to malfunction.
CHECK all spray equipment regularly and repair or
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
recommendations on additional protective equipment,
such as a respirator.
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.
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 cover). Always read the chemical
manufacturer’s 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.
ALL FLUID HOSES MUST HAVE 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.
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.
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.
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
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 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.
NEVER alter the throttle setting, which is factory set.
Tampering with this adjustment can damage the
pressure washer and will void the warranty.
