Maintenance
Servicing the Cutting Blades
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.
WARNING
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 blades periodically for wear or
damage.
• Replace a worn or damaged blade.
Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the blades and
set the parking brake. Turn the ignition key to off. Remove
the key and disconnect the spark plug wires from the spark
plugs.

Service Interval: Before each use or daily
1. Inspect the cutting edges ( Figure 61 ).
Note:
If the edges are not sharp or have nicks, remove
and sharpen the blades; refer to Sharpening the Blades
