HOW TO SHARPEN
THE BLADE
WARNING: Vibration
can be caused if the blade is
_i
ot 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 a Sears 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 a qualified 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".
