WARNING

 - When using this pressure washer, basic precautions should always be followed, including the following: 

1.)  Read all the instructions before using this product. 
2.)  To reduce the risk of injury, close supervision is necessary when the pressure washer is used near 

children. Do not allow irresponsible use by children. Always stop the unit and bleed or relieve pressures 
before leaving unattended, disconnecting hoses, or servicing the pump. 

3.)  Know how to stop the unit and bleed pressures quickly.  Be thoroughly familiar with the controls. 
4.)  Stay alert - watch what you are doing. 
5.)  Do not operate when fatigued or under the influence of alcohol or drugs.  Never smoke while operating 

or fueling this machine. 

6.)  Keep operating area clear of all persons.   
7.)  Do not overreach or stand on unstable support.  Keep good footing and balance at all times. Wear 

footwear capable of maintaining a good grip on wet surfaces. Do not place the machine on soft or 
unstable ground. 

8.)  Follow the maintenance instructions specified in all manuals.  Do not run machine without sufficient 

lubrication or sufficient water to cool the pump. 

9.)  Wear safety glasses, gloves, face protection and appropriate clothing when operating the machine. 
10.) Do not operate this machine with broken or missing parts.  Never alter the manufacturer’s original design 

or deactivate any safety device on the machine. 

11.) Risk of exposure to dangerous chemicals.  Wear protective gloves when handling and cleaning with 

chemicals.  Follow the chemical manufacturer’s directions. Understand all safety hazards and first aid for 
all chemicals being used. Check whether dangerous chemicals have been used and take any 
precautions that may have been recommended by the supplier of these chemicals when cleaning filters.  
Do not pump highly abrasive fluids or use with incompatible chemicals or solvents. 

12.) Know the pressure and temperature limits of your machine.  Be sure all high pressure accessories meet 

or exceed your machine’s limits. Do not set the pressure relief valve above the machine’s limit. 

13.) Do not move this machine by pulling on the hose. 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. 

14.)To reduce risk of injury, do not secure the spray gun open. Your spray gun is equipped with a built-in 

trigger safety latch to guard against accidental trigger release and potentially dangerous high pressure 
spray.  Rotate the safety latch to the locked position when not spraying. 

15.) Do not clean this machine with its own spray.  Cleaning should be done with a damp sponge with the 

engine OFF.
