Starter cord kickback (rapid retraction) can result in

bodily injury. Kickback will pull hand and arm toward

engine faster than you can let go. Broken bones,

fractures, bruises, or sprains could result.

• NEVER pull the starter cord without first relieving the spray gun

pressure.

• When starting the engine, pull the cord slowly until resistance is

felt, then pull rapidly to avoid kickback.

• After each starting attempt, where engine fails to run, always point

the spray gun in a safe direction and squeeze the spray gun trigger
to release high pressure.

• Firmly grasp the spray gun with both hands when using high

pressure spray to avoid injury when the spray gun kicks back.

7. Return the starter grip handle slowly. DO NOT let the rope

“snap back” against the starter.

8. When the engine starts, slowly the move choke lever to the

“OPEN” position as the engine warms. If the engine falters,

move the choke lever to the “CLOSE” position, then to the

“OPEN” position (Figure 29).

9. After each starting attempt, where the engine fails to run,

always point the gun in a safe direction, and squeeze the

spray gun trigger to release high pressure.

10. If the engine fails to start after six pulls, move the choke lever

to the “OPEN” position, and repeat steps 6 through 10.

The high pressure stream of water that this equipment

produces can cut through skin and its underlying

tissues, leading to serious injury, possible amputation

or death. Spray gun traps high water pressure, even

when engine is stopped and water is disconnected,

which can cause injury.

• DO NOT allow CHILDREN to operate the power washer or play

nearby.

• Keep the high pressure hose connected to the pump and spray gun

while the system is pressurized.

• NEVER aim the spray gun at people, animals or electrical devices.

Serious injury will result.

• DO NOT secure the spray gun in the open position.

• DO NOT leave the spray gun unattended while the machine is

running.

• NEVER use a spray gun which does not have a trigger lock or

trigger guard in place and in working order.

• Always be certain the spray gun, nozzles and accessories are

correctly attached.

Contact with the muffler area can result in
serious burns. Exhaust heat/gases can ignite
combustibles, structures or damage the fuel
tank causing a fire.

• DO NOT touch hot parts and AVOID hot exhaust gases.

• Allow the equipment to cool before touching.

• Keep at least five (5) feet (152 cm) of clearance on all sides of the

power washer including overhead.

• It is a violation of California Public Resource Code, Section 4442,

to use or operate the engine on any forest-covered, brush-covered,

or grass-covered land unless the exhaust system is equipped with

a spark arrester, as defined in Section 4442, maintained in effective

working order. Other states or federal jurisdictions may have

similar laws.

• Replacement parts must be the same and installed in the same

position as the original parts.

AUTOMATIC COOL DOWN SYSTEM (THERMAL
RELIEF)

If you run the engine on your power washer for 3-5 minutes

without pressing the trigger on the spray gun, circulating water

in the pump can reach temperatures above 125°F. The system

engages to cool the pump by discharging the warm water onto

the ground.

ADJUSTABLE PRESSURE SETTING

Your pressure washer pump is equipped with a feature that allows

you to adjust the pressure setting. The pump is preset at the

factory to achieve the highest possible pressure. To decrease the

pressure, turn the pressure control knob counterclockwise to the

desired pressure. Turning the pressure control knob clockwise

until it stops will set the pressure back to the factory setting.
