4. Remove the blade.
NOTE: The blade spacer and a bearing protector
will come off with the blade. The bearing pro-
tector and the space must be installed in the
same order when installing the blade.
See Figure 8.5.
5. Install the blade by following the above steps in
reverse order. Tighten the blade nut to a torque of
100 - 120 ft-lbs (136 - 163 Nm).
NOTE: A 1 1/8” wrench can be used to hold the top
of the spindle shaft.
Sharpening the blades:
• To properly sharpen the cutting blades, remove equal amounts of metal from both ends of the blades along the
cutting edges, parallel to the trailing edge, at a 25° to 30° angle.
• Sharpen the top of the blade only, maintaining the factory cutting edge angle.
IMPORTANT: It is important that each cutting blade edge be ground equally to maintain proper blade balance.
IMPORTANT: Replace any blade with severe nicks or dents that cannot be removed by filing.
• The blade can be tested by using a blade balancer. Grind metal from the heavy side until it balances
evenly.
