The air cleaner is a dry type with replaceable filter cartridges. A definite time schedule for changing the
filter cartridge cannot be determined because of varying operating conditions. Change the filter
cartridge when the green indicator "flag" reaches the top of the viewing chamber and locks in that
position. Change the cartridge as follows:
a. Cartridge Removal (See Fig. 5)
(1) Remove air cleaner access panel from rear of unit.
(2) Remove clamp assembly (2) from air cleaner.
(3) Remove baffle assembly (3) .
(4) Remove primary element (4) , and replace with new element.
CAUTION
(5) Inspect the interior of the cleaner housing (7) . Make certain it is free from all foreign material.
b. Cartridge Installation (See Fig. 5)
(1) Carefully install the new cartridge into the housing. Avoid bumping the cartridge tubes against
the housing sealing flange. Seat the cartridge properly within the housing. Press all edges and
corners of the cartridge firmly with fingers to effect a positive air seal against the sealing flange
of the housing.
CAUTION
(2) Lock the cartridge in place by installing the baffle assembly (3) and clamp assembly (2) with cup
assembly (1) in place. Tighten clamp (2) down in place.
5. Engine Fuel

performance. Fuel oil must be clean, completely distilled, stable, and non-corrosive. Only distillate
fuel No. 1d is recommended for use both summer and winter.
