Removing and Replacing the Swinging Blades
NOTE: Replace the Blade(s) when worn or damaged.
Tools and Supplies needed:
•
Two 15/16" Wrench
•
Gloves
1.
Using two 15/16" Wrenches, remove the Top Lock Nut (right-hand, regular thread), the Backing Nut, and then the Blade Bolt
followed by the Pro-Tek™ Swinging Blade (
Figure 23 ).
2.
Reinstall the sharpened or a new Pro-Tek™ Swinging Blade in the orientation shown ( Figure 24 ).
3.
Install the Backing Nut until it seats finger tight against the Blade Carrier to allow for the Blade Swinging action ( Figure 23 ).
4.
Using two 15/16" Wrenches, install and tighten the Lock Nut against the Backing Nut while holding the Backing Nut with one
Wrench and tightening the Lock Nut with the other Wrench.
5.
Repeat steps 1 through 3 for the other Pro-Tek™ Swinging Blade.
When performing any adjustment or maintenance, you must first shut off the engine, wait five (5) minutes to allow parts to cool
and disconnect the spark plug wire(s), keeping it away from the spark plug(s).
Use caution when pushing or pulling the wrench next to the blade. Wear gloves; if the wrench slips off the bolt, you may be
seriously injured.
