Operation
Startup
Always use this start-up procedure to ensure that the pressure washer is started safely and properly.
D Always engage the gun trigger safety latch when
you stop spraying even for a moment. This reduces
the risk of fluid injection or splashing in the eyes or
on the skin if the gun is bumped or triggered
accidentally.
D Always observe the CAUTIONS in this section to
avoid costly damage to the pressure washer.
D If you use the Sandblaster Kit, see the Sandblaster
Kit manual for detailed cleaning information.
1. Check the oil level.
NOTE: All pressure washers are equipped with a
low-oil sensor that shuts the engine off if the oil
level falls below a certain level. If the engine stops
unexpectedly, check both the oil and the fuel
levels. Check the oil level each time you refuel.
2. Check the fuel level.
WARNING
FIRE HAZARD
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. Turn on the water supply.
CAUTION
Never run the pressure washer without water.
Costly damage to the pump will result. Always be
sure the water supply is completely turned on
before you run the pressure washer.
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. Be sure the spark plug
ignition cable is pushed firmly onto the spark plug.
Put the switch in the START position, and put the
throttle in the RUN position.
CAUTION
Do not allow the pressure washer to idle for more
than 10 minutes. Doing so could cause the
recirculating water to overheat and seriously
damage the pump. Turn off the pressure washer if
it will not be spraying at least every 10 minutes. If
heated inlet water is used, reduce this time more.
Do not operate the pressure washer with the inlet
water screen removed. The screen helps keep
abrasive sediment out of the pump, which could
clog the pump or damage the cylinders. Keep the
screen clean. Do not pump caustic materials; such
materials could corrode the pump components.
6. Pull the starter rope to start the engine. Brace one
foot on the pressure washer chassis, and pull the
starter rope out quickly. Pull and return the rope
until the engine starts.
CAUTION
Do not allow the starter rope to snap back against
the engine. Let the rope recoil gently to prevent
damage to the recoil.
NOTE: For easier starting, have one person start
the pressure washer while another person triggers
the gun.
If the engine is cold, start the engine with the
choke completely closed. In cool weather, you
might have to let the engine run with the choke
closed for the first 10 to 30 seconds. In warm
weather, open the choke completely as soon as
the engine starts.
If the engine is warm, start the engine with the
choke completely open or partially closed. When
the engine starts, open the choke completely.
