Chemical Injector

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

WARNING

Observe chemical manufacturer ’s safety precautions regarding use of goggles, protective clothing or respirators.

1026 & 1530: 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. Push the nozzle holder on the end of the wand away from the gun. This causes a drop in pressure that actuates the chemical injector. Pull the nozzle holder to deactivate the chemical injector and produce high pressure for rinsing. The flowrate of the chemical is regulated by turning the chemical adjuctment knob on the injector . Maximum chemical flow is at a full two turns counterclockwise from the closed (clockwise) position. T wisting the nozzle holder will change the spray fan angle.

2340: The chemical injector is an accessory. See the chemical injector instruction manual.

WARNING

DO 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 wook, 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.

Trigger Safety Latch

WARNING

To reduce the risk of serious bodily injury

,

including fluid injection, splashing in the eyes or

 

on the skin, ALWAYS engage the trigger safety

 

latch whenever spraying stops, even for a

 

moment.

 

In the engaged position, the trigger safety latch prevents the gun from being triggered accidentally by hand or if it is dropped or bumped. Be sure the latch is pushed fully down when engaging it or it cannot prevent the gun from being triggered. See Figure 2.

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 of f 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.
