Graco Inc. 308-517 Pressure Washer User Manual


 
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 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
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.
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.
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 RELlEFS 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.
HANDLEAND ROUTEHOSES 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 Grace hose to
temperatures above 200” F (93” C) or below -40” F
(-40” C).
MOVING PARTS HAZARD
Moving parts can pinch or amputate fingers or other
body parts.
KEEP CLEAR
of moving parts when starting
or operating the pressure washer.
Pressure Relief Procedure
before checking or
servicing the pressure washer to prevent discharging
high pressure fluid from the gun.
NEVER
operate the pressure washer without all guards
and interlocks installed and functioning. Follow the
