1. Cleaning the Intake Air Filter,
a. Checkand clean the air filter often. The fil-
ter needs cleaning if you can see a film of
dust on it. It will need cleaning more often
in dusty air.
b. Pull out the filter element out of the housing
and wash it with a mild detergent and hot or
cold water. (See figure 2.)
c. Dry thoroughly and install filter.
CAUTION: Do not oil the filter element.

2. Cleaning the Fan,
Cleanthe fan blades after every 500 hours of op-
eration, or whenever you see that they are getting
dirty. A build-up of dirt will reduce the air supply and
cause faulty operation.
To clean, wipe the blades with a cloth moistened
with kerosene or solvent. Be careful not to bend the
blades. Dry the fan thoroughly.
3. ‘Motor Lubrication,
The ball bearing on the pump-end of the motor
is lubricated for the life of the motor. Do not lubri-
cate it.
Oil the sleeve bearing at the fan-end of the motor
once a year with 10 to 20 drops of Mobil DTE-LC or
DTE-23 oil.

prevent loosening when the heater is
moved.
3. Be sure all parts are in place and all
screws and electrical connections are
tight, before attempting to use the heat-
er. Take care not to damage the spark
plug, andto keep the proper gap between
its electrodes.
6. Lubrication.
Lubricate the sleeve bearing at the fan end of the
motor as specified in paragraph 3.
