GENERAL RECOMMENDATIONS

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.

WARNING: Before you make an inspection, adjust- ment, or repair to the unit, disconnect the wire to the spark plug. Remove the wire from the spark plug to prevent the engine from starting by accident.

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.

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.

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.
