Startup

Always use this startup procedure to ensure that the unit is started safely and properly.

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: 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

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 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. Be sure the spark plug ignition cables are pushed firmly onto the spark plugs. Put the ignition shutoff switch in the ªonº position and the throttle in the ªrunº 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.

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.
