Operation
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 ªonº position and put the throttle in the ªrunº position.
CAUTION
Do not allow the pressure washer to idle for more than 10 minutes. Doing so may cause the recir- culating 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 operate the pressure washer with the inlet water screen removed. This screen helps keep abrasive sediment out of the pump, which could clog the pump or damage the cylinders. Keep this screen clean. Do not pump caustic materials; such materials may corrode the pump components.
CAUTION
Do not allow the starter rope to snap back against the engine. Return it gently to prevent damage to the recoil.
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.
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.
9.See the sandblaster kit manual for detailed clean- ing information if this accessory is used.
