Check for Shipping Damage

Check the unit for any damage that may have occurred in shipping. Notify the carrier immediately if there is any damage.

Set Up

Connect the high pressure hose between the pump outlet and the gun inlet. Both of these connections are made with quick couplers.

CAUTION

Up to 100 ft (30 m) of high pressure hose may be used. Longer hoses may affect sprayer performance, and chemical injector performance, if used.

Install the appropriate spray tip on the wand. See Installing and Changing Spray Tips. If you are using a sandblaster kit, see its separate manual for installation instructions.

Connect to Water Supply

CAUTION

Before attaching to the water supply, check your local plumbing code regarding cross±connection to the water supply. If required, a backflow preventer may be installed.

If inlet water pressure is over 60 psi (4.1 bar), a regulating water valve must be installed at the garden hose connection.

Do not exceed 160_F (70_C) inlet water temperature.

Connect a hose with at least a 3/4 inch (19 mm) ID from the water supply to the unit's 3/4 inch garden hose inlet. The supply hose should not be more than 50 ft (15 m) long

NOTE: The water source at the unit must have a minimum flow rate equal to that of the unit (see Technical Data, inside back cover).

Operation

Pressure Relief Procedure

WARNING

INJECTION HAZARD

The system pressure must be manually

relieved to prevent the system from spraying accidentally. To reduce the risk

of an injury from accidental spray from the gun, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:

Dare instructed to relieve the pressure,

Dstop spraying for more than 10 minutes,

Dcheck or service any of the system equipment,

Dor install or clean the spray nozzle.

Startup

Always use this start±up procedure to ensure that the unit is started safely and properly.

1. Check oil levels:

NOTE: All units are 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.

Pressure Relief Procedure

1.Engage the trigger safety latch.

2.Turn the sprayer off.

3.Remove the ignition cable from the spark plug.

4.Shut off the water supply.

5.Disengage the trigger safety latch and trigger the gun to relieve pressure, and then engage the trigger safety latch again.

6.If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the steps above:

Disengage the trigger safety latch and trigger the gun to relieve pressure. Wrap a rag around the hose end coupling and VERY SLOWLY loosen the coupling to relieve pressure gradually, then loosen completely. Now clear the tip or hose.

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.

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.

3. Turn on the water supply.

824±001 5

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 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 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 cleaning information if this accessory is used.
