Air Cleaner
The PT 70/80 are equipped with two air filter elements
to remove contaminants from the air used for combus-
tion. Regular inspection and replacement is necessary
to ensure proper performance and to prolong engine
life.
To remove and inspect your air cleaner elements:
1. Turn the engine off.
2. Open the hood at the rear of the machine to gain
access to the engine compartment.
3. Locate the black air cleaner enclosure near the top
left of the engine compartment (when viewed from
the rear).
4. Twist the tension screw (A) counter-clockwise until
the band is loose enough to remove the cover,
then remove the cover. The primary element (B)
should be exposed.
5. Remove the primary element and inspect it. If it
appears damaged in any way, replace it. If the ele-
ment is heavily soiled, replace it. If it appears to be
in good condition, clean if necessary and re-install.
6. Once the primary element has been removed, the
secondary element (C) should be visible. Remove
and inspect it. If the element is damaged or heavily
soiled, replace it.
Note: The secondary element is not serviceable. It
should be replaced after every three cleanings of the
primary filter.
Note: The primary element may be cleaned and reused
up to five times if properly maintained, but should be
replaced at least once a year.
