This power sprayer troubleshooting section shows how to diagnose and resolve problems that
may  occur  in  the  course  of  normal  operation.  If  you  experience  a  problem,  take  the  steps
indicated for the applicable diagnosis.  When you can't determine the cause of a problem or
if  you  have  any  difficulty,  please  feel  free  to  contact  your  nearest  dealer  or  this  company's
sales  office.  Please  have  the  following  information  ready:    1.  Model  designation    2.  Serial
number    3.  Description  of  problem  (What  happened?  What  were  you  doing  when  it
happened? What were the conditions when it happened?)  For items marked with *, please
request adjustment or repair from your nearest dealer or from this company's sales office.

WARNING:

Do  not  change  the  setting  of  the  screw  that  is  under  the  cap  on  the  top  of  the

pressure regulator knob. This screw absolutely must not be changed, since that will raise the
pressure above rated specifications, damage the machine, and possibly cause injury.
