SERVICING THE MOWER BLADES
WARNING
Do not handle the blade with bare hands. Do not touch
the cutting edge.
Sharpening & Balancing
1. To remove a blade, wedge a wood block between blade
and housing to prevent rotation. Then, turn capscrew
counterclockwise to remove.
2. Use a file to sharpen blade to a fine edge. Remove all
nicks and dents in blade edge. If blade is severely
damaged it should be replaced.
3. To balance the blade, use a balancing machine or the
following procedure. Drive a small nail into the side of a
workbench or other vertical surface. Lubricate the nail
with a drop of oil. Center the blade center hole on the
nail. A balanced blade will remain level. File material off
heavier end of blade until it is balanced.
Blade Installation
1. Reinstall the blade(s) with the tabs pointing upward.
Install the spline washer, cup washer, and capscrew (see
figure 20). Be sure the splines on the spline washer are
engaged with the shaft splines. Be sure cup washer is
installed with the concave side up.
2. To tighten the capscrew, wedge a wood block between
blade and housing to prevent blade from turning.
Torque the capscrew to 50 to 70 ft. lbs. (68-76 Nm).
