OPERATING INSTRUCTIONS
Start-up
Refer to the “Safety Precautions” pgs. 3-5 before start-
ing the unit.
Locate the Safety Decals on your unit and heed their
warnings.
Never look directly into the nozzle. High pressure water
creates a risk of severe injury.
1. With the gun locked in the “OFF” position, point the
trigger gun away from yourself or anyone else. Ensure
the water supply is completely turned on.
2. Disengage the safety lock-off on the gun and squeeze
the trigger. Low pressure water will begin owing from
the nozzle.
3. Be certain the trigger gun remains in an open position
while starting the engine. Brace yourself as the gun
will kickback from the high pressure created by the
pump once the engine has started.
4. Steady the unit during engine start-up. (Refer to the
engine manual accompanying this pressure washer for
the correct procedures needed to start the engine.)
5. Once the engine has started, perform the following
procedures with the gun open:
Inspect for system oil leaks and fuel leaks. If a fuel leak
is found, turn unit off immediately. See “Fire & Ventila-
tion Precautions” pg. 4. Be sure that all damaged parts
are replaced and that the mechanical problems are
corrected prior to operation of the unit. If you require
service, contact Graco Customer Service.
Inspect high pressure hoses for kinking, cuts and leaks.
If a cut or leak is found, do not touch hose at leak. Turn
unit off immediately. Replace hose before restarting the
unit. See “Miscellaneous Safety Precautions” pg. 5. Be
sure that all damaged parts are replaced and that the
mechanical problems are corrected prior to operation of
the unit. If you require service, contact Graco Customer
Service.
6. Trigger the gun several times. Be certain to lock the
trigger gun in the “OFF” position whenever changing
the quick connect nozzles.
NOTICE
Do not allow unit to operate in bypass mode (with
trigger closed) for more than three minutes without
triggering the gun. Failure to follow this simple rule
can cause premature failure of pump packing seals,
resulting in costly pump repair.
Because your pressure washer delivers a high pressure
spray and a variety of spray patterns, there are many
cleaning jobs that can be done without the use of de-
tergents. If a cleaning agent is required, see “Cleaning
With Detergents” pg. 13 for the correct procedures.
NOTICE
Do not allow spray pattern to remain on a xed area
for an extended period of time. Possible damage
may occur to the area.
