GETTING  STARTED:   

If  your  dealer  has  not 

prepared the machine for startup, you may need to 
connect  the  hose  to  the  pressure  outlet  on  the 
washer and connect the other end of the hose that 
swivels to the trigger gun inlet and tighten.  Mobile 
Wash Skids are engine powered and shipped from 
the  factory  with  the  fuel  tanks  empty  and  without 
the  battery.    Fill  the  battery  to  the  fill  line  with 
electrolyte (available through your dealer or a local 
auto parts store).  Connect the battery cables, and 
follow  the  operation  instructions  for  starting.  
Pressure  Steamers  are  electric  powered  and  will 
require  an  appropriate  electric  outlet  or  disconnect 
box  and  an  electric  plug  that  is  rated  for  your 
machine’s  voltage  and  amperage  and  matches  to 
your  electrical  socket.    Smaller  machines  are 

equipped  with  a  ground  fault  interrupter  on  the 
electrical cord and you will need to press the reset 
button  after  it  is  plugged  in.    (See  Operating 
Instruction 

section 

and
