High pressure fluid in the hoses can be very dangerous. If the hose develops a leak, split or rupture due to any kind of wear, damage or misuse, the high pressure spray emitted from it can cause a fluid injection injury or other serious bodily injury or property damage.

ALL FLU/D HOSES MUST HAVE STRAIN RELEFS ON

BOTH ENDS. The strain reliefs help protect the hose from kinks or bends at or close to the coupling, which can result in hose rupture.

TlGHTEN all fluid connections securely before each use. High pressure fluid can dislodge a loose coupling or allow high pressure spray to be emitted from the coupling.

NEVER use a damaged hose. Before each use, check entire hose for cuts, leaks, abrasion, bulging cover, or damage or movement of the hose couplings. If any of these conditions exist, replace the hose immediately. DO NO7 try to recouple high pressure hose or mend it with tape or any other device. A repaired hose cannot

contain the high pressure fluid.

Connect to Water Supply

CAUTION

Before attaching to the water supply, check your local plumbing code regarding cross- connection

to the water supply. A backflow preventer P/N 801-l 33 is available to

prevent backflow of contaminated water into the fresh water supply. Install it upstream from the

pump. Install a regulating water valve, P/N 800-258, if

inlet water pressure is over 60 psi (4.1 bar). Do not exceed 160” F (70” C) inlet water

temperature.

Connect the high pressure hose between the pump outlet and the gun inlet.

Up to 100 ft (30 m) of high pressure hose may performance, and chemical injector performance,

Connect a hose with at least a 314 inch (19 mm) ID and not longer than 50 ft (15 m) to the unit’s 3/4 inch garden hose inlet.

NOTE:

The water source at the unit musl have a minimum flow rate equal to that of the unit (see Technical Data, page 22).

308-518 5

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. 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.

Trigger the gun until water sprays from the tip

3. indicating that the air is purged from the system.

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

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.

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.

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.

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

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 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.

DO NOT pump caustic materials; such materials

may corrode the pump components.
