HIGH PRESSURE WASHING
(Water and Mild Solvent)
High pressure cleaning with water and mild solvent is advisable provided the following points are
observed.
A. Begin wash down by flooding entire machine with solution. This assists in floating abrasive
particles off the machine, which might otherwise be blown into bearings and other critical surfaces as
the cleaning procedure continues. A safe distance of 2 to 3 feet between nozzle and machine is
recommended.
B. Avoid close contact of nozzle to machine (less than 12" to 15"), as high pressure jet stream at
this distance imparts a cutting action which could lift and remove paint where worn or broken spots
in paint occur. In addition, close nozzle contact may also blow grease from bearings and other
lubricated surfaces, leaving exposed parts susceptible to rusting.
NOTE:
Lubricate all bearings and other lubricated surfaces after washing and run machine
for a short period to aid in moisture removal.
C. Engine may be washed totally, but avoid trapping moisture in electrical components, and do not
wash a "hot" engine with cold water, as the differential in temperature could cause cracking of
exhaust manifold and other cast components.
D. Mild solvents of a non-flammable nature may be suitable for cleaning, provided manufacturer's
specs are compatible with alkyd enamels, rubber and plastics as used on the self-propelled combine
units.
E. Using steam as a cleaning agent is not recommended by ALMACO, as steam is viewed as a
potentially destructive agent to plastics, paint and rubber and promotes rust and corrosion of
components, which are not immediately protected after cleaning.
