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”.
