SAFETY WARNINGS   

 

 

 

 

 

 

 

9.  Transformer  on  burner  is  20,000  volts.  
Disconnect battery cable before servicing burner or 
engine on 12-volt systems. 
 
 
 

FIRE PRECAUTIONS: 

1.  DO  NOT  use  improper  fuels  or  solvents  in  this 
equipment, and only fill with the correct fluids when 
the  unit  is  in  an  OFF  condition,  main  power  is 
disconnected, and engine and burner are cool. 
2.  Fill  the  diesel  burner  fuel  tank  with  #2  diesel 
fuel, kerosene, or approved alternate fuel.  NEVER 
use  gasoline.    Do  not  confuse  gasoline  and  diesel 
fuel tanks. 
3.  NEVER operate this equipment in the presence 
of  flammable  vapors,  dust,  gases,  or  other 
potentially combustible materials. 
4.  AVOID contact with the exterior of the coil/heat 
exchanger assembly, mufflers, and exhaust port or 
stack to prevent burns. 
5.  DO NOT store fuel or other flammable materials 
near the burner or any other open flame. 
6.  Diesel  fired  or  gasoline  power  units  are 
designed for outdoor use and installation only. 
7.  Burner on/off switch must be placed in the OFF 
position  when  the  pressure  washer  is  not  being 
used.  Do not depend on engine run switch to turn 
the burner off 

– this may cause a safety hazard. 

8.  Warning:    Burner  (water  heater)  should  start 
only  when  water  is  sprayed.    Stop  the 
system/engine  immediately  if  burner  continues  to 
fire when trigger gun is off. 
 

VENTILATION PRECAUTIONS: 

1.  Do  not  run  engine  or  burner  in  an  enclosed 
area.  Exhaust gases contain carbon monoxide, an 
odorless, deadly poison. 
2.  Observe  all  State,  Local,  and  National  codes 
providing for indoor use or installation of this unit. 
3.  Provide  adequate  ventilation  to  prevent  engine 
overheating and inefficient burner combustion (min. 
2’ air space).  Do not restrict normal engine airflow. 
4.  For engine driven units mounted in a van or box 
truck  type  vehicles,  provide  an  external  engine 
exhaust  line  that  is  larger  in  diameter  than  the 
factory  exhaust  pipe  and  vent  the  exhaust  to  the 
outside  of  the  vehicle,  but  not  below  the  vehicle’s 
interior floor height.  Also, insure adequate fresh air 
circulation  within  the  van  for  engine  cooling 
purposes  to  prevent  heat  build-up  and  for  engine 
fresh  air  intake.    Clearance  of  at  least  12”  is 
recommended  on  all  sides  of  the  unit.    Provide  a 
burner  exhaust  vent,  at  least  8”  diameter,  to  the 
outside  through  the  van  roof,  or  though  the  side 

panel  that  is  at  least  10”  in  diameter,  and  position 
this  vent  to  avoid  water,  dirt  and  debris  collection.  
No  flammable  liquids,  aerosols,  or  flammable 
materials should be stored within 24” of the unit and 
should  not  be  stored  under  the  unit.    During 
refueling, ALL ignition sources and switches should 
be  OFF  and  there  should  be  a  person  with  the 
proper  fire  extinguisher  and  training  within  the 
vicinity of the unit in case of fire.  Unit should not be 
left running unattended or out of site. 

 
SPRAY INJECTION PRECAUTION: 

1.  Fluid  from  high-pressure  spray  or  leaks  can 
penetrate the skin and cause serious injury.  If any 
fluid  appears  to  penetrate  the  skin,  get  emergency 
medical  help  at  once.  DO  NOT  treat  as  a  simple 
cut.    Tell  the  physician  exactly  what  fluid  was 
injected.    For  treatment  instructions,  have  the 
physician  call  your  local  poison  center.    Without 
proper treatment, complications can develop. 
2.  WARNING 

– Risk of injection or severe injury to 

persons 

–  Keep  clear  of  nozzle.    DO  NOT  direct 

discharge stream at people.  This machine is to be 
used  by  trained  operators.    Keep  operating  area 
clear  of  all  people.    U

se  only  48”  long  wands  on 

machines producing over 3000 PSI.  Also, only use 
straight wands or wands with a bend of 10° or less.  
CAUTION:  Hot discharge fluid 

– DO NOT touch or 

direct discharge stream at people.  Gun kicks back 
–  Hold  with  both  hands.    Stay  alert  –  Watch  what 
you are doing. 
3.  Always  wear  protective  eye  goggles  when 
operating  the  equipment.    Additional  protective 
items such as a rubber suit, gloves, and respirators 
are  advisable,  particularly  when  using  cleaning 
detergents with a corrosive content. 
4.  Know the detergents you are using.  Read and 
follow the directions on the detergent labels. 
 

PERSONAL HAZARD: 

1.  Shut  unit  off  and  disconnect  power  before 
removing belt guards or electrical covers. 
2.  Shut unit off before moving it. 
3.  NEVER lock the trigger on the gun valve in the 
on position. 
4.  Do 

not 

exceed 

recommended 

operating 

pressure or temperature. 
5.  Observe  all  regulations  when  towing  trailer-
mounted units. 
6.  Keep  hands  clear  of  belts:    Some  units 
equipped  with  auto-on  may  start  at  any  time  when 
power is connected. 
7.  Do  not  operate  the  product  when  fatigued  or    
under the influence of alcohol or drugs. 
 

Warning:  FIRE OR EXPLOSION HAZARD CAN CAUSE
