Air filter
Generally air filters come in two different types, a
pleated-paper element or foam. A combination of the two
are used on the MTD engine. See Figure 3.1.
• Air filters used on the MTD engine are designed to
prevent particles larger than 3-5 micron from pass-
ing through into the engine.
• The filter should be checked on a regular basis
possibly several times in a season.
NOTE: Never use compressed air on a paper air filter.
Compressed air will remove the tiny fibers that are
used to catch the dirt in the air. Without these
fibers the filter is useless.
NOTE: Refer to Chapter 1: Introduction for the mainte-
nance interval and cleaning instructions for the air
filter.
To remove/replace the air filter:
1. Wipe down the air filter housing to prevent any debris
from getting into the engine.
2. Un-screw the two wing nuts. See Figure 3.2.
NOTE: The wing nuts are part of the air filter cover and do
not come off.
