WARNING
The blades are sharp; contacting a blade could
result in serious personal injury.
• Disconnect the wire from the spark plug.
• Wear gloves when servicing the blade.
Inspecting the Blades
Service Interval: Before each use or daily
1. Inspect the cutting edges (Figure 42). If the edges
are not sharp or have nicks, remove the blades and
have them sharpened or replace them.
2. Inspect the blades themselves, especially the curved
area (Figure 42). If you notice any damage, wear, or
a slot forming in this area (Figure 42), immediately
replace it with a new blade.

DANGER
If you allow a blade to wear, a slot will form
between the sail and flat part of the blade.
Eventually a piece of the blade may break off
and be thrown from under the housing, possibly
resulting in serious injury to you or bystanders.
• Inspect the blade periodically for wear or
damage.
• Never try to straighten a blade that is bent or
weld a broken or cracked blade.
• Replace a worn or damaged blade.
3. Check for bent blades; refer to
Checking for Bent Blades (page 21).
Checking for Bent Blades
1. Rotate the blades until they are positioned as shown
in Figure 43.

at locations A and B, (Figure 43), and record both
dimensions.
3. Rotate the blades so that their opposite ends are at
locations A and B.
4. Repeat the measurements in step 2 and record them.
Note: If the difference between the dimensions A
and B obtained in steps 2 and 4 exceeds 1/8 inch
