5. Turn the motor switch to the ON position
6. Set the fuel valve to the OPEN position.
7. Engage the choke (if cold starting) and set
the throttle to 3 ⁄
4
open.
8. Squeeze the spray gun trigger until a steady
stream of water comes out, then release.
10. Pull the start rope to start the motor.
Note: For best pull-starting results, pull the
start rope with forceful, but even pressure to
spin the motor.
When pull-starting, pull the start rope slowly
until resistance is felt, then pull with forceful,
even pressure. Rapidly jerking the start rope
can cause it to forcefully recoil, potentially
causing hand and/or arm injury.
11. Allow the motor to run long enough to achieve
normal operating temperature (at least two
minutes), then set the throttle to the desired
speed.
12. Pull the trigger on the spray gun to release
pressurized water and begin work.
Note: If the motor does not start after several
pulls of the start rope, or brief turns of the
start switch, repeat the starting instructions
from
Step 8. If you are still unable to start the
motor, refer to the troubleshooting guide on
Page 20.
NOTICE
Never allow the motor to run for more than
five minutes without pulling the trigger
on the spray gun to release water. Failure
to follow this instruction can damage the
pump and void the warranty.
Shutdown Procedure
To shut down the pressure washer:
1. Release the trigger on the spray gun and
return the spray gun to the bracket on the
washer handle.
2. Turn the pressure adjustment knob
counterclockwise until there is no more
pressure.
3. Close the fuel valve.
4. Switch the motor to the OFF position.
5. Shut off the water at the spigot, or remove
the input hose from the water if drawing from
a standing source. Purge the pressure from
the system by pulling the spray gun trigger.
NOTICE
To reduce the risk of damaging engine
components, DO NOT stop the engine
abruptly when it is running under load.
