Operation
Pressure Relief Procedure
WARNING
INJECTION HAZARD
System pressure must be manually
relieved to prevent system from starting
or spraying accidentally. Fluid under high
pressure can be injected through skin and cause
serious injury. To reduce risk of injury from injec-
tion, splashing fluid, or moving parts, follow Pres-
sure Relief Procedure whenever you:
D are instructed to relieve pressure,
D stop spraying for more than 10 minutes,
D check or service system equipment,
D install or clean spray nozzle.
1. Engage trigger safety latch.
2. Turn sprayer off.
3. Remove ignition cable from spark plug.
4. Remove siphon tube from water supply.
5. Disengage trigger safety latch and trigger gun to
relieve pressure. Engage trigger safety latch.
6. If spray tip or hose is completely clogged, or
pressure has not been fully relieved after following
steps above: Disengage trigger safety latch and
trigger gun to relieve pressure. Wrap rag around
hose end coupling and VERY SLOWLY loosen
coupling to relieve pressure gradually, then loosen
completely. Now clear tip or hose.
Startup
1. Check oil levels.
D Engine: Add SAE 30 or 10W–30 weight deter-
gent oil as necessary.
D Pump: Add SAE 20 or 30 weight non–deterg-
ent oil.
NOTE: This pressure washer is 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
FIRE HAZARD
Do not refuel a hot engine. Refueling a
hot engine could cause a fire. Use only
fresh, clean regular or unleaded gaso-
line. Close fuel shutoff valve during refueling.
3. Turn on the water supply.
CAUTION
Never run unit dry. Costly damage to pump will
result. Always be sure water supply is sufficient
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. Be sure the spark plug
ignition cables are pushed firmly onto the spark
plugs. Put the ignition shutoff switch in the “on”
position and the throttle 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. Press the start button. 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
partially closed. Start the engine as described in the
preceding paragraph. When the engine starts, be
sure to open the choke completely.
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.
