Air filter and foam pre cleaner
A dirty air filter and/or foam pre cleaner can reduce
engine power, increase fuel consumption and make
starting more difficult.
The foam pre cleaner should be checked before
each use and cleaned every 25 hours.
The air filter should be cleaned before each use
and replaced every two months or 50 hours of use.
To check the air filter and pre cleaner:
1. Swing open the air filter door located at the front
of the engine. See Figure 9.3.
2. Lift up the wire retainer. See Figure 9.4.
