MACHINE!! ---

STEAM OPERATION:

1. Follow steps 1-7 of Start-up / Cold-Water Operation.
2. Move switch to burner position.
3. Recheck the system for water leaks and fuel leaks. If a leak is found,
TURN UNIT OFF IMMEDIATELY! See "Risk of Explosion or Fire, pg.
5)
NOTE: Upon initial start-up, water will begin turning hot in approximately
20 seconds and will reach steam temperature in approximately 5
minutes providing the trigger remains squeezed. The burner will
not fire when the trigger is released.
At this point, the unit will operate as a steam pressure washer. Be extremely
cautious when adjusting the pressure and controlling the trigger gun/dual
lance assembly to avoid the possibility of burns.

CLEANING WITH DETERGENTS:

NOTE: This feature is designed for use with mild detergents only. Since the
cleaning solution travels through various parts of the pressure washer,
do not use corrosives as they will cause extensive damage as well as
pose a considerable safety hazard.
1. Refer to "Risk of Bodily Injury/Detergents" pg. 7. Be certain to wear protective
safety attire as stated on pg. 10.
2. Prepare detergent solution according to label directions. (Never pump acids,
alkalines, abrasive fluids or solvents through the unit. Due to the unknown
and often corrosive characteristics of many detergents commonly used in
the pressure washer cleaning industry, it is recommended to use only mild
detergents with this unit.)
3. Fully immerse the strainer end of the clear vinyl detergent hose into the
detergent solution.
4. Adjust the amount of detergent desired by turning the detergent metering
valve [shown at right] completely counterclockwise to set at maximum siphon
rate.
5. To apply solution; unlock the trigger gun and squeeze the trigger. In a few
moments a detergent/water mixture will exit the nozzle. Start spraying the
lower portion of the surface being cleaned and move up, using long overlapping
strokes. Applying from the bottom up helps avoid streaking. Allow to soak
briefly. Avoid working on hot surfaces or in direct sunlight to minimize the
chances of the detergent drying, which may result in damaging surfaces.
Be certain to apply cleaning solution to a small section at a time.
6. To rinse; lock the trigger gun in the "OFF" position. Turn the detergent
metering valve to the "OFF" position. Unlock the trigger gun and spray. It
will take about 30 seconds to purge all detergent from the line. For best
rinsing results, start at the top and work down.
7. Siphon a gallon of water through the detergent injection system after each
use. This prevents the possibility of corrosion or detergent residue causing
mechanical problems during the next use.
