Important Safety Instructions

DANGER: Carbon Monoxide. Using an engine indoors can kill

you in minutes. Engine exhaust contains high levels of carbon

monoxide (CO), a poisonous gas you cannot see or smell. You

may be breathing CO even if you do not smell engine exhaust.

WARNING: This product and its exhaust contain chemicals

known to the State of California to cause cancer, and birth

defects and other reproductive harm.

 NEVER use an engine inside homes, garages, crawlspaces or

other partly enclosed areas. Deadly levels of carbon monoxide

can build up in these areas. Using a fan or opening windows and

doors does NOT supply enough fresh air.

 ONLY use outdoors and far away from open windows, doors and

vents. These openings can pull in engine exhaust.

Maintenance

WARNING: Risk of burning. When performing maintenance, you

may be exposed to hot surfaces, water pressure or moving parts that

can cause serious injury or death.

WARNING: Risk of fire. Always disconnect, spark plug wire, let

the engine cool and release all water pressure before performing

any maintenance or repair. The engine contains flammable fuel. Do

not smoke or work near open flames while performing maintenance.

To ensure efficient operation and longer life of your pressure washer,

a routine maintenance schedule should be prepared and followed.

If the pressure washer is used in unusual conditions, such as high

temperatures or dusty conditions, more frequent maintenance

checkswillberequired.

Engine

Consult the engine instruction manual for the man u fac tur er's recom-

mendations for any and all maintenance.

NOTE:Thepressurewasherframeisequippedwithanoildrain

hole to help make changing the engine oil easier.

Pump

NOTE: The pump was filled with oil at the factory. Change pump oil

after the first 50 hours of operation and every 300 hours thereafter,

or every 3 months. If using a 30W non-detergent oil, change oil every

150 hours thereafter.

TO CHECK OIL

The oil level should come to the dot in the middle

2. Place a container under the oil drain plug

(CC).

3. Remove pump oil drain plug.

4. After oil is drained, replace oil drain plug.

Tighten securely.

5. Remove pump oil plug and fill with pump oil. An oil designed spe-

cifically for pressure washers is recommended as these contain a

rust inhibitor and an anit-foaming agent. If this oil is not available,

an SAE 30W non-detergent oil may be used.

6. Replace pump oil plug and tighten securely.

Nozzle Cleaning

If the nozzle becomes clogged with foreign materials, such as dirt,

excessive pressure may develop. If the nozzle becomes partially

clogged or restricted, the pump pressure will pulsate. Clean the

nozzle immediately using the nozzle kit supplied and the following

instructions:

1. Shut off the pressure washer and turn off the water supply.

2. Pull trigger on gun handle to relieve any water pressure.

3. Disconnect the spray wand from the gun.
