re-start the mower for at least one minute, allowing for
the motor time to cool.
2. Press the overload protection switch inward
to reset. See Figure 4-2 in Operation section.

re-start the mower for at least 15 minutes to allow the
motor extra time to cool.
2. Press the overload protection switch inward to reset.
3. Restart unit.

4. The blade can be sharpened with a file or on a
grinding wheel. Do not attempt to sharpen the blade
while it is still on the mower. When sharpening blade,
follow original angle of grind. Grind cutting edges
equally to keep blade balanced.
5. Remove blade from the adapter for testing balance.
Balance the blade on a round shaft screwdriver to
check. Remove metal from the heavy side until it
balances evenly.
WARNING: An unbalanced blade
will cause excessive vibration when
rotating at high speeds. It may cause
damage to mower and could break
causing personal injury.
6. Place the cutting blade, locking plate, and blade bolt
on the motor shaft and thread the blade bolt in finger
tight. Refer to Figure 5-3.
NOTE: Make certain to replace the parts in the exact
order in which they were removed. When installing the
cutting blade, be sure it is installed with the curved ends
pointing towards the mower deck and not towards the
ground.
7. Torque the blade bolt down using a torque wrench to
assure the bolt is tightened properly. The recom-
mended torque for the blade bolt is 170-220 in. lbs.
WARNING: The blade hardware is not
only used to attach the blade as-
sembly, but is also an insulated safety
device and should never be altered in
any way. If replacement is necessary, use original
equipment parts as shown in the parts list.
To ensure safe operation of your mower, periodically
check the blade bolt for correct torque.
