H. Climate Guard Air® Cleaner
Some engines are equipped with an optional Climate
Guard Air Cleaner or Climate Guard. See Figures 15 and
16.
I. Moving The Inlet Air Scoop
For smooth and efficient engine operation, the inlet air
scoop must be aimed toward the engine and away from the
muffler for proper ambient air temperature to reach the
engine.
1. Remove the wing nut from the top of the air cleaner.
2. Lift the cover of the air cleaner.
3. Rotate the scoop to the desired position.
4. Replace the cover.
5. Install and tighten the wing nut.
NOTES
If the engine is not equipped with a CLIMATE GUARD air
cleaner, a CLIMATE GUARD Conversion Kit is available at
any Authorized Tecumseh Servicing Dealer. See Figure 15.
If the engine is equipped with a CLIMATE GUARD, no
changes need to be made when changing from summer to
winter operation. See Figure 16.
I. Winter Application
In temperatures below 32°F ( 0°C), the inlet air scoop
should be pointed directly at the muffler.
II. Summer Application
In temperatures above 32°F ( 0°C), the inlet air scoop
should be pointed toward the blower housing
(approximately 45° clockwise from ”WINTER” position).
