To Start You r Pressu re Washer

To start your pressure washer for the first time_follow these

instructions step=by=step.This starting information also applies if

you have let the pressure washer sit idle for at least a day.

. Place the pressure washer in an area close enough to an

outside water source capable of supplying water at a flow

rate greater than 2.2 gallons per minute.

. Check that the high pressure hose is tightly connected to

the spray gun and to the pump. See "Preparing Pressure

Washer For Use" for illustrations.

o Hake sure unit is in a level position.

° Connect the garden hose to the water inlet on the

pressure washer pump. Turn ON the water.

CAUTION! Do Not run the pump without the water

supply connected and turned on.You must follow this

caution or the pump will be damage&

° Squeeze trigger on gun until you have a steady stream of

water.This purges the pump of air and impurities.

. Attach nozzle extension to spray gun (Figure I I).Tighten

by hand.

o Position the nozzle in the low pressure mode (slide

nozzle forward) and squeeze the trigger on the spray gun

to relieve pressure caused by turning ON the water.

VVater will flow out of the gun in a thin stream. Continue

to hold trigger until there is a steady stream of water

and no air remains in the system. Release the trigger.

° Engage the safety latch to the spray gun triger

(Figure 12).

o Hove the throttle lever to "Fast" position, shown here

as a rabbit (Figure 13).

Throttl

Choke Lever

o Hove the choke lever to the "Choke" position

(Figure 13).

NOTE: For a warm engine, be sure the choke lever is in

the "P_un" position.

o Place your left foot on the lower frame and grasp the

handle as shown (Figure 14).Your unit may appear slightly

different from that shown here.

For Rinsing:

, SHidethe nozzHe backward to high pressure and press the

trigger. It wiHHtake a few seconds for the detergent to

clear.

NOTE:You can aHsostop detergent from flowing by simpHy

removing detergent siphon tube from botde.

, Keep the spray gun a safe distance from the area you

pHanto spray.

" AppHy a high pressure spray to a smaHHarea, then check

the surface for damage. If no damage is found, it is okay

to continue rinsing.

° Start at the top of the area to be rinsed, working down

with same overHappingstrokes as you used for cHeaning.

Automatic Cool Down System

(Thermam Remief}

If you run the engine on your pressure washer for

3=5minutes without pressing the trigger on the spray gun,

circuHating water in the pump can reach a temperature

between H25°-H 55°EWhen the water reaches this

temperature, the automatic cool down system engages and

cooHs the pump by discharging the warm water onto

the ground. This system prevents internaH damage to the

pump.

Nozzle Maintenance

A puHsing sensation fek whiHe squeezing the spray gun

trigger may be caused by excessive pump pressure.The

principa[ cause of excessive pump pressure is a nozzHe

c[ogged or restricted with foreign materiak such as dirt,

etc.To correct the problem, immediately clean the nozzle

using the tooHs incHuded with your pressure washer and

foHHow these instructions:

I. Shut off the engine and turn off the water supply.

the nozzHe c[ockwise to the stream position. Using the

suppHied 2ram (5/64) aHHen wrench, remove the nozzHe

from the end of the nozzHe extension (Figure 21).

3. Remove the inoline filter from the other end of the

nozzHe extension.

4. Use the wire incHuded in the kit (or a smaHHpaper chip)

O-Rin 8 Maintenance

Through the normal operation of your pressure washen

o-rings, which keep the connections of the hoses and spray

gun tight and leak-free, may become worn or damaged.

Provided with your pressure washer is an O-Ring

Haintenance Kit which includes rephcement o-rings, rubber

washer and water inlet filter. Refer to the instruction sheet

provided in the kit to service your unit's o-rings. Note that

not all of the parts in the kit will be used on your unit.

To remove a worn or damaged o-ring:

Use a small flathead screwdriver to get underneath the

o-ring and pry it off.

ENGINE MAINTENANCE

See the engine owner's manual for instructions on how to

properly maintain the engine.

CAUTION! Avoid prolonged or repeated skin

contact with used motor oil. Used motor oil has

been shown to causeskin cancer in certain

laboratory animag.ThorougNy wash exposed areas

with soap and water.

KEEP OUT OF REACH OF CHILDREN. DON'T

POLLUTE. CONSERVE RESOURCES. RETURN

USED OILTO COLLECTION CENTERS.

PREPARING THE UNIT

FOR ,STORAGE

Water should not remain in the unit for long periods of

time. Sediments or minerals can deposit on pump parts and

"freeze" pump action. If you do not plan to use the pressure

washer for more than 30 days, follow this procedure:

I. Flush detergent siphoning tube by placing the filter into

a pail of clean water while running pressure washer in

low pressure mode (adjustable nozzle in the forward

position). Flush for one to two minutes.

2. Shut off the engine and let it cool, then remove high

pressure and garden hoses. Disconnect spark plug wire

from spark plug.

3. Empty the pump of all pumped liquids by pulling the

recoil handle about 6 times.This should remove most

of the liquid in the pump.

4. Use Generac brand PumpSaver to prevent corrosion

build up and freezing of pump.

5. Store unit in a clean, dry area.

Protecting the Pum

To protect the pump from damage caused by mineral

deposits or freezing, use the Generac PumpSaver to treat

pump.This prevents freeze damage and lubricates pistons

and seals.

NOTE: Generac PumpSaver, model number 01559, is available

as an optional accessory. It is not included with the pressure

washer.

CAUTION!You must protect your unit from freezing
