Air filter (summer engines)
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 1.3.
1.
The main function of the air filter is to trap air borne
particles before they enter the engine. Dirt ingestion
can cause serious internal engine damage.
NOTE: Snow engines do not have air filters
because the snow will plug up the filter. Gen-
erally the air is clean enough that there is
minimal risk of dirt ingestion when the
ground is covered with snow.
2.
Air filters used on the MTD engine are designed to
prevent particles larger than 3-5 micron from pass-
ing through into the engine.
3.
The filter should be checked on a regular basis pos-
sibly several times in a season.
4.
Typically an air filter should be changed before every season.
5.
If a foam air pre-cleaner is dirty, but not in bad of condition it can be cleaned and reused. The paper pleated fil-
ters can be shaken or lightly tapped to free the debris from the filter.
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.
6.
Foam pre-filters can be washed in warm soapy water.
NOTE: When drying a foam filter either squeeze it in side of a paper towel or let it air dry DO NOT wring it
because the filter will tear.
7.
Before installing any foam filter, after it has been washed, it needs to be free of moisture.
NOTE: Always check with factory specification prior to servicing/replacing any engine components.
NOTE: Do not oil the foam pre-filter. The paper filer will absorb the oil and it will become plugged.
