Maintenance
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 operating condition.
WARNING
Before you make an inspection, 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 the Blade
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 (see Figure 7). Frequently check the blade
for excessive wear, cracks,or other damage.
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 damage.
Before you operate the unit, replace damaged parts
with original equipment parts. See the authorized serv-
ice center in your area. Every three years, have an au-
thorized service person inspect the blade or replace
the old blade with an original equipment part.

rotating.
3. Remove the nut (3) that holds the blade (1) (see
