STARTUP
Use this procedure whenever starting the pressure
washer
to help
insure that the unit is ready to operate and
starting
is done safely
.
1.
Check oil levels.
Engine:
Add SAE 30 or 10W–30 weight detergent oil
as
necessary
.
Pump:
Add SAE 20 or 30 weight
non–detergent oil as
necessary.
NOTE:
Some
units are equipped with a low–oil sensor
that shuts the engine off if the oil level falls
below a certain level. If the unit stops
unexpectedly, check both the oil and the fuel
levels.
Check the oil level each time the unit is
refueled.
2. Check
fuel level.
WARNING
DO NOT
refuel a hot engine. Refueling a hot
engine
could cause a fire. Use only fresh, clean
regular or unleaded gasoline. Close the fuel
shutoff
valve during refueling.
3. T
urn on the water supply
.
CAUTION
Never run the unit dry. Costly damage to the
pump will result. Always be sure the water
supply is completely turned on before
operating.
4. Trigger the gun until water sprays from the tip
indicating
that the air is purged from the system.
5. Open the fuel shutoff valve and be sure the spark
plug ignition cable is pushed firmly onto the spark
plug.
On
those units equipped with an ignition shutof
f
switch, the switch should be in the “on” position.
Throttle
should be in the “run” position.
6.
Start the engine.
NOTE: For easier starting, have one person start the
pressure
washer while
another person triggers
the
spray gun.
If the engine is cold, completely close the engine
choke.
Grasp the starter rope, brace one foot on the
pressure washer chassis and pull rope rapidly and
firmly. Continue holding the rope as it returns. Pull
and return the rope until the engine starts. In cool
weather,
the
choke may have to be kept closed for 10
to 30 seconds before opening it to keep the engine
running. Otherwise, open the choke as soon as the
engine
starts.
If the engine is warm, leave the choke open, or just
partly close it. Start the engine as described in the
preceding
paragraph. When it starts, be sure to open
the
choke completely
.
CAUTION
On
recoil start engines, never let the starter rope
return
by itself. It could jam the recoil system.
7.
ALWAYS
engage the gun’s trigger safety latch
whenever
you stop spraying, even for a moment,
to
reduce the risk of fluid injection or splashing in the
eyes
or on the skin if the gun is
bumped or triggered
accidentally.
8.
ALWAYS
observe the following
CAUTIONS
to
avoid
costly
damage to the pressure washer
.
CAUTION
DO NOT
allow the pressure washer to idle for
more
than 10 minutes. Doing so may cause the
recirculating water to overheat and seriously
damage the pump. Turn off the pressure
washer if it will not be spraying or cleaning at
least every 10 minutes. If heated inlet water is
used,
reduce this time further
.
DO NOT
run the pump dry, which will quickly
damage
the pump. Be sure the
water supply is
fully
turned on before starting the pump.
DO
NOT
operate the pressure washer with the
inlet
water
screen removed. This screen helps
keep
abrasive sediment out of the pump, which
could clog or scratch the pump. Keep this
screen
clean.
DO NOT
pump caustic materials; such
materials
may corrode the pump components.
9. See the chemical injector or sandblaster kit manual
for
detailed cleaning information if these accessories
are
used.
