1. The owner's responsibility is to maintain this product. This will
extend the life of the product and is also necessary to maintain
warranty coverage.
2. Check the spark plug, drive brake, lubricate the unit, and clean
the air filter once a year.
3. Check the fasteners. Make sure all fasteners are tight.
4. Follow the Maintenance section to keep the unit in good operat-
ing condition.

HOW TO CHECK THE MUFFLER

Check the muffler every 50 hours. Make sure the muffler is correctly
mounted and is not loose. If the muffler is worn or burnt, replace with
a new muffler. A worn muffler is a fire hazard and can also damage
the engine.

USE
NOTE: Torque is measured in foot pounds (metric Nm). This
measurement describes how tight a nut or bolt must be. The
torque is measured with a torque wrench.
If you mount a spark arrester to the muffler, also check the spark
arrester when you check the muffler. If the spark arrester is worn or
damaged, replace it with a new spark arrester. See your nearest
authorized service center for a spark arrester.
