How to Sharpen the Blade
WARNING: Vibration can be caused if the blade is
not correctly balanced or if the blade is damaged. A
blade that is damaged with cracks can break and
cause an accident.
Keep a sharp edge on the
blade
. A
blade
that is not sharp
will cause the tips of the grass to become brown.
1. Sharpen the
blade
two times a year or every 25 hours.
2. Remove the
blade
according to the instructions in
“How To Remove And Install The Blade”.
3. Clean the
blade
with a brush, soap and water. Check
the
blade
. Look for cracks, nicks, or other damage.
Replace a badly worn or damaged blade with an
original equipment blade. See an authorized service
center in your area.
4. Sharpen the
blade
with a
file
(Figure 21). Make sure
you keep the original bevel angle.
5. Make sure the
blade
is balanced. Use a
screwdriver
and hold the
blade
parallel to the
ground
(Figure 21). A
blade
that is balanced will stay parallel to the
ground
. If
the
blade
is not balanced, the heavy end will rotate
toward the
ground
. Sharpen the heavy end until the
blade
is balanced.
6. A new blade will cut better than a badly worn blade.
Every three years, have an authorized service person
inspect the blade or replace the old blade with an
original equipment blade.
7. Assemble the
blade
according to the instructions “How
To Remove And Install The Blade”.
