OPTIONS OPERATION
HIGH PRESSURE SPRAYER
The high pressure sprayer option gives the
machine the ability to spray wash grease, oil, and
other dirt from trucks, racks, walls, etc. The water
and detergent solution is taken from the solution
supply line located under the operator seat. The
solution is directed first to the spray pump which
is driven off the machine hydraulic system. The
spray pump has a 4 gpm (15 L/min) capacity up
to 800 psi (5515 kPa). From the pump, the water
flows through the hand-held sprayer.
NOTE: Pump only approved machine detergents
and solutions through the high pressure sprayer .
Acids and abrasive fluids may damage the unit.
The engine idle must be set between 700 and
850 rpm to allow the pump to operate at normal
speed.
