308532

Operation

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 gasoline. 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.

Operation

CAUTION

Pressure washer is equipped with a thermal relief valve. If pressure washer is operated without spraying for an extended period (approximately 10 minutes) the valve will expel hot water.

Do not operate pressure washer with inlet water screen removed. Keep screen clean. Screen keeps abrasive sediment out of pump, Abrasive sediment can clog pump or damage cylinders.

Do not pump caustic materials; such materials may corrode pump components.

9. See the chemical injector or sandblaster kit manual for detailed cleaning information if these accessories are used.

Trigger Safety Latch
