General Recommendations
1. The owner's responsibility is to maintain this
product. This will extend the life of the prod-
uct and is also necessary to maintain war-
ranty 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 operating condition.
WARNING: Before you make an in-
spection, adjustment, 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.

Inspect Blade (Figure 13)
WARNING: Before you inspect or
remove the blade, disconnect the
wire to the spark plug. If the blade
hits an object, stop the engine. Check the
unit for damage. The blade has sharp
edges. When you hold the blade, use
gloves or cloth material to protect your
hands.
If you keep the blade (1) sharp and inspect the
blade for damage, the blade will cut better and
be more safe to operate. Frequently check the
blade for excessive wear, cracks, or other dam-
age. Frequently check the nut (3) that holds the
blade (1). Keep the nut (3) tight. If the blade hits
an object, stop the engine. Disconnect the wire
to the spark plug. See if the blade is bent or
damaged. Check the blade adapter (5) for dam-
age. Before you operate the unit, replace dam-
aged parts with original equipment parts. See
the authorized service centre in your area. Every
three years, have an authorized service person
inspect the blade or replace the old blade with
an original equipment part.
