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.
Inspecting the Blades
Service Interval: Before each use or daily
1. Inspect the cutting edges (Figure 62). If the edges
are not sharp or have nicks, remove and sharpen the
blades. Refer to Sharpening the Blades.
