5.3 PRIME THE PUMP
When using the pressure washer for the first time or after a long storage period, follow this procedure to
ensure that the pump primes:
1. Prepare unit and worksite. Turn on the supply water.
2. Hold the trigger for at least one minute until the spray leaves the nozzle in a steady stream (no
sputtering).
3. Start the engine.
4. Always use this technique after the pressure washer is brought out of storage. The pump may lose its
prime during storage and this allows it to prime quickly.
5.4 STARTING/STOPPING THE PRESSURE WASHER
To start or stop the pressure washer, follow this procedure:
1. Starting
a) Review Section 5.2.
b) Make sure that water is available to the pump by turning on water from the garden hose line.
c)
CHECK THE OIL LEVELS IN THE PUMP
AND ENGINE
(see Section 5.2).
d) Ensure the pump is primed (see Section 5.3).
e) Install the spark plug wire if it was removed.
f) To start the engine, refer to the engine owner’s manual.
2. Stopping
a) If it is necessary to stop washing, release the spray gun trigger and flip the safety latch into
position under the trigger.
b) Lay the spray gun down.
c)
IMPORTANT!
The pump goes into
bypass
when the gun trigger is released and the motor is still
running. Exit bypass by pressing the gun trigger to spray water.
DO NOT LET THE PUMP
REMAIN IN BYPASS FOR LONGER THAN 1-2 MINUTES
. Prolonged bypass will damage the
pump.
d) For
complete
shutdown:
i.
Move the throttle control lever to the idle position to reduce engine speed (RPM).
ii. Turn the engine switch to the OFF position.
iii. Turn off the outside water supply.
iv. Continue to depress the spray gun trigger until the water stops flowing to relieve the internal
pressure.
v. Remove the spark plug wire to prevent accidental start up.
vi. Refer to Section 6.2.1 if the unit will see freezing temperatures during its shutdown or storage
period.
