Important
Refer to your engine operator's manual for additional maintenance procedures.
If you leave the key in the ignition switch, someone could accidently start the engine and
seriously injure you or other bystanders.
Remove the key from the ignition and disconnect the wire from the spark plug(s) before you do
any maintenance. Set the wire aside so that it does not accidentally contact the spark plug.

Cutting Blade Service

To ensure a superior quality of cut, keep the blades sharp.
For convenient sharpening and replacement, you may
want to keep extra blades on hand.

A worn or damaged blade can break, and a piece
of the blade could be thrown into the operator's
or bystander's area, resulting in serious personal
injury or death.
Inspect the blade periodically for wear or
damage.
