This unit has a steel coil which, after setting, will cause the water remaining in 

the coil from the  previous usage to turn brown or black.  This water must be 

flushed from the system before start-up.  This procedure should be performed  

without  the high pressure hose, gun and dual lance assembly installed.  

1.  Turn on the water supply.
2.  Move the switch to the "Pump" position.  Low pressure water will begin 

flowing from the water outlet.  This allows the unit to flush any particles from 

the system.  The unit is flushed when the water is clear.

3.  Once the system is flushed, move the switch to the "OFF" position and 

connect the high pressure hose to the water outlet of the unit.   

4.  Connect the trigger gun and dual lance assembly to the high  

pressure hose.

1.  Refer to the "Safety Precautions" pgs. 4-7 before starting the unit.
2.  Locate the Safety Decals on your unit and heed their warnings.
3.  Ensure that the switch is in the "OFF" position.
4.  Pointing    the  trigger  gun  in  a  safe  direction,  unlock  the  trigger  gun  and 

squeeze the trigger.  Brace yourself for possible gun kickback when the 

pump starts.

5.  Move the switch to the "Pump" position.   
6.  Once the unit has started, perform the following procedures with the gun 

open:

 a.  Inspect  for  system  water  leaks,  oil  leaks  and  fuel  leaks.  

If a fuel leak is found, TURN UNIT OFF IMMEDIATELY!   See "Risk of  

Explosion or Fire", pg. 5.  Be sure that all damaged parts are replaced  

and that the mechanical problems are corrected prior to operation of 

the  unit.  If you require service, contact Customer Service.

 b.  Inspect  high  pressure  hoses  for  kinking,  cuts  and  leaks. 

If a cut or leak is found, DO NOT TOUCH HOSE AT LEAK!!!   TURN UNIT 

OFF IMMEDIATELY! 

 Replace hose before starting the unit.  See "Risk  

of Injection or Severe Cutting Injury" pg. 6.  Be sure that all damaged 

parts  are  replaced  and  that  the  mechanical  problems  are  corrected 

prior to  operation of the unit.  If you require service, contact Customer 

Service.

7.  At this point, the unit is operating as a cold water pressure washer.  Trigger 

the gun several times and try adjusting the water pressure by rotating the 

grip on the dual lance.  NEVER place hand or fingers in front of the nozzle 

or look directly into the nozzle!  High pressure water creates a risk of severe 

injury!

8.  Do not allow unit to operate in bypass mode (with trigger closed) for more 

than three minutes without triggering the gun.  Failure to follow this simple 

rule can cause premature failure of pump packings, resulting in costly pump 

repair.

9.  Your pressure washer can deliver high pressure spray and a variety of spray 

patterns using cold water.  If you wish to use the Hot Water, Steam application 

or Cleaning with Detergents, see page 18 for the correct procedures.
