Summary of Important Information 

 

47 

dangerous chemicals have been used with the filter and take any precautions that may have been recommended by the supplier 
of these chemicals.  Always dispose of hazardous fluids per local, state, and national guidelines. 

 

Do not exceed pressure and or temperature limits

. Do NOT operate this pump with components (such as hose, connections, 

and spray gun) rated for lower pressure and or temperature limits than the machine's maximum rated pressure and temperature, 
or component could rupture and cause serious personal injury from escaping high pressure fluids.  Do not set the pressure relief 
valve above the rated pressure. 

If the high-pressure relief valve ever discharges water, turn the engine off and do not use 

the machine.  The valve will no longer function properly.  See a dealer or call Product Support at 1-800-270-0810.

 

 

Never pull by hose

.  Do not move this machine by pulling on the hose.  Hose or connections could fail and result in 

catastrophic high-pressure release of fluid as well as hose whipping. 

 

Avoid sharp objects

.  Keep hose away from sharp objects.  Bursting hoses may cause injury. 

 

No load bearing

. Do not use the pump to support other items of equipment that impose unacceptable loads on the pump. Do 

not attempt to use this machine as a prop. 

 

Hot exhaust/parts

. Stay clear of engine exhaust.  Never touch hot engine muffler or other hot surfaces.  All are very hot and 

will burn you.   

 

Smoking/sparks

.  Never smoke near the running engine, and never operate near sources of sparks or flames as flammable fuel 

vapors are in the vicinity of the pressure washer. 

 

Lock trigger safety latch when not spraying

.  Spray gun is equipped with a built-in trigger safety latch to guard against 

accidental trigger release.  Rotate safety latch to the locked position when not spraying. 

 

Relieve water pressure.

  Always stop the product and relieve system pressure before leaving the sprayer unattended, or when 

disconnecting hoses, removing nozzles, or servicing the pump. 

 

Refueling

.  Never add gasoline to the engine unless unit is off and has cooled. 

 

Do not direct spray at this machine.

 Do not attempt to clean this machine with its own spray.  Engine damage will result. 

Cleaning should be done with a damp sponge with the engine OFF. 

 

Seek medical aid for suspected carbon monoxide poisoning

.  The running engine gives off carbon monoxide, a poisonous 

gas that can kill you.  If you start to feel sick, dizzy, or weak while using the pressure washer, shut off the engine and get to 
fresh air RIGHT AWAY.  See a doctor. You may have carbon monoxide poisoning. 

 

Seek medical aid for suspected injection injury

. If injured by high-pressure fluid, no matter how small the wound is, see a 

doctor at once.  A typical injection injury may be a small puncture wound that does not look serious.  However, severe 
infection or reaction can result if proper medical treatment is not administered immediately by a doctor who is familiar with 
injection injuries.

 

 

Other exhaust dangers

.  This product contains or emits chemicals known to the State of California to cause cancer, birth 

defects or other reproductive harm.  Avoid inhalation of exhaust. 

 

After use 

 

Cool engine before storing.  

Let engine cool for at least five minutes before storing.  A hot engine is a fire hazard.

 

 

Prevent accidental starting.

  When pressure washer is not in use, remove spark plug or spark plug wire in order to ensure 

that pressure washer cannot be started in a storage location or by untrained persons. 

 

Storage location.

  Store the pressure washer in a dry location away from sources of heat, open flames, sparks or pilot lights – 

such as water heaters, space heaters, furnaces, clothes dryers, or other gas appliances – EVEN IF the pressure washer's gas 
tank is empty, residual vapors or fuel could ignite.

 

 

 

Periodic maintenance.

  Perform periodic maintenance as directed in this manual to keep the pressure washer in safe working 

condition. 

 

 

 

Safety - Inspection/Maintenance 

Inspect and maintain your pressure washer on a regular basis and repair as needed to keep it in safe working condition:   

 

Turn off / relieve pressure first.  

Turn off pressure washer and relieve system pressure before inspection or maintenance.  

Remove spark plug or spark plug wire before working on the engine or pressure washer to prevent accidental starting.  

 

Fuel valve off.

  Turn fuel shut-off valve to OFF position before transporting or servicing the pressure washer. 

 

Follow maintenance schedule.

  Follow all maintenance instructions in this pressure washer manual and the engine manual. 

 

Replace guards / shields.

  Make sure all guards and shields are replaced after servicing the pressure washer. 

 

Replacement parts.

  If a part needs replacement, 

only use factory approved repair parts

.  Replacement parts that do not 

meet specifications may result in a safety hazard or poor operation of the pressure washer and will void the warranty.
