Use this procedure whenever starting the pressure washer to help insure that the unit is ready to operate and starting is done safely.

1.Check the oil level.

Pump: Add SAE 20 or 30 weight non-detergent oil as necessary.

2.Turn on the water supply.

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.Trigger the gun until water sprays from the tip indicating that the air is purged from the system.

4.Plug the electrical cord into a proper, grounded, GFCI-protected outlet.

5.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.

6.Most pressure washer spraying is done at full pressure. On this pressure washer there is an adjustable unloader valve that permits operation at less than maximum pressure. To reduce pressure, for special cleaning applications, turn the pressure control knob on the unloader counterclockwise, as needed.

7.ALWAYS observe the followinq CAUTIONS to avoid costly damage to the pressu‘;e washer.

CAUTION

DO NOTallow 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 NOToperate 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.

8.See the chemical injector or kit manual for detailed cleaning information if this accessory is used.

Chemical Injector

BE SURE that all chemicals used in the chemical injector are compatible with the wetted pans of the hose, gun, wand and tip, as given in the Technical Data (page 22). Always read the chemical manufacturer’s literature before using any chemical in this pressure washer.

826:A downstream chemical injector is provided with the pressure washer. Insert the chemical strainer (attached with clear tubing to the chemical injector) into the container of chemical. Turn the control ring on the adjustable nozzle clockwise. This causes a drop in pressure that actuates the chemical injector. Close the adjustable nozzle to deactivate the chemical injector and produce high pressure for rinsing. The flowrate of the chemical is regulated by turning the chemical adjustment knob on the injector. Maximum chemical flow is at a full two turns counterclockwise from the closed (clockwise) position.

1235: The chemical injector is an accessory. See the chemical injector instruction manual.

WARNING

rDO NOT attempt to open or close the adjustable nozzle when the spray gun is in use. Be sure that the trigger safety latch on the gun is in the “ON” position before adjusting to avoid serious bodily injury or fluid injection.

Check the distance that you will need to hold the spray nozzle from the surface by test spraying on a scrap of similar material. For soft surfaces, such as wood, hold nozzle 3 ft (1 m) from the surface and gradually bring it closer, checking to see if the high pressure spray is damaging the surface.

Mist the wet surface with cleaning solution. Let it soak briefly, then use the high pressure rinse to “chisel” off the soil. Keep the nozzle at an angle to the surface and at a distance determined to be best for the surface. If some soil remains, repeat the procedure, letting the chemical soak a little longer. Stubborn soil can be cleaned off better with a stronger, heated cleaning solution.

Protect surfaces that might be damaged by the cleaning solution or the high pressure spray. Rinse the solution before it dries.
