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
