(2) Operation in Hot and Humid Conditions

a. Cooling system
Maintain a more frequent check of the coolant level in the radiator.

(3) Operation in Extremely Dusty Conditions

If unit is to be operated under dusty, out-of-door conditions, place it in a sheltered area. Take
advantage of any natural barriers which may offer protection from blowing dust. If the installation
is more than temporary, erect a protection shield.
a. Fuel system
Change the fuel filter at prescribed intervals and keep fuel containers covered and protected
against dust entry.
b. Air Cleaner
This filter needs more frequent attention under dusty conditions. Check Air Filter Restriction
Lamp located on control panel daily.
c. Crankcase Oil
The crankcase oil level will require close attention. Dusty conditions tend to load crankcase
oil with dirt. Watch for dirty and gritty oil conditions, and change oil more frequently as
required.

(4) Operation in Salt Water Areas

a. Canopy
Wash canopy regularly to remove salt film. Repaint any damaged places and oil the hinges
regularly.
b. Covering
To protect the engine and generator as much as possible from salt water atmosphere, keep
the side doors on the canopy closed, when not in use. It is advisable to keep the unit covered
with a tarpaulin, if available, when not in use. Salt water should be wiped from the engine,
and all terminals and connections in the electrical system wiped dry. Keep all linkage oiled.
c. Brushes
The brushes of the generator should be inspected regularly to make certain that they are free
in the holders. Lift the brushes in the brush holders about every two days to insure their
freedom to slide within the holder. Wipe dry all the parts that can be reached, and use
compressed air, if available, to dry the parts of the generator that cannot otherwise be
reached. See MAINTENANCE for brush care.
d. Field coils
The fields should be dried as thoroughly as possible. If they have become damp, proceed
with recommended procedure in MAINTENANCE section.
e. Battery terminals
Thoroughly clean the battery terminals and connections. Coat terminals and connections with
petroleum jelly to retard corrosion.
(5) Miscellaneous
Once a month, oil the hinged plexiglass cover.
