tions carefully before using.

  1.   Read  the  owner's  manual 

thoroughly.  Failure  to  fol-
low instructions could cause

and  result  in  death,  serious 
bodily injury and/or property 
damage.

  2.  All  installations  must  comply  with  local  codes.

— Use this product only in a well 
ventilated area.

  3.  Avoid  installing  machines  in 

small areas or near exhaust 
fans.  Exhaust  contains  poi-
sonous carbon monoxide gas;  
exposure may cause loss of 
consciousness and may lead  
to death. It also contains 

    chemicals known, in certain quantities, to cause 

cancer, birth defects or other reproductive harm.

liquids.

    4. Do not place machine near flammable objects as 

the engine is hot.

  5.  Allow engine to cool for 2 minutes before refuel-

ing.  If  any  fuel  is  spilled,  make  sure  the  area  is 
dry before testing the spark plug or starting the 
engine. (Fire and/or explosion may occur if this is 
not done.)

    Refuel  gasoline  engines  on  mobile  or  portable  

equipment:

    a.  outdoors;
    b.  with the engine on the equipment stopped;
    c.  with no source of ignition within 10 feet of  

 

the dispensing point; and

    d.  with an allowance made for expansion of the  

 

fuel should the equipment be exposed to a  

 

higher ambient temperature.

    In an overfilling situation, additional precautions are 

necessary to ensure that the situation is handled 
in a safe manner. 

WARNING:  High  pressure  De-
veloped  by  these  machines 
will  cause  personal  injury  or 
equipment damage. Keep clear 
of nozzle. Use caution when op-
erating. Do not direct discharge 
stream  at  people,  or  severe 
injury or death will result.
