STORAGE INSTRUCTIONS
DANGER: Do not store flammable liquids (gasoline,
diesel fuel, petroleum, solvents, etc.) near pressure
washer, or in non-ventilated areas.
IMPORTANT: Machine must be stored indoors.
1.
Protect from freezing by storing in a heated area,
or by flushing the system with antifreeze (use an
automotive engine antifreeze or windshield washer
solvent to antifreeze). To flush the system fill the float
tank with antifreeze and remove pressure nozzle from
wand. Start the machine and allow it to run until an-
tifreeze runs from the end of the wand. Place wand
into float tank and circulate the solution through sys-
tem for several minutes. Open and close the trigger
gun several times to circulate antifreeze through the
unloader valve system. Also draw antifreeze through
the detergent inlet line to antifreeze the detergent
system. For added protection after antifreezing, dis-
connect the pressure hose from machine and remove
the coil drain plug (refer to
Component Identifica-
tion
illustration for location). After coil has drained,
replace pressure hose and coil drain plug. If the pres-
sure washer is not to be used for an extended length
of time, it is recommended that the system be flushed
with antifreeze for rust protection.
