WARNING!
never mow with dull blades. Blades
that are bent should be replaced. The cutting blades
are sharp and can cause severe injury. Wrap the
cutting surface of the blade with a rag to avoid
injury.
Sharpening the Blades
1. Set the parking brake.
2. Clean any debris from the blades. Keep blades sharp and
free of build up at all times.
3. Sharpen blades evenly at the original 30° angle to maintain
balanced cutting blades. Do not sharpen the underside of
the blades. Use a electric blade sharpener, a conventional
electric grinder or a hand file to sharpen the blades.
4. Replace any blade with severe nicks or dents that cannot
be removed by filing.
5. Check the balance of the blade after sharpening by placing
it on a blade balancer. Do not use un-balanced blades.
6. If the blade dips on one end, file stock off of the cutting
surface on that end.
NOTE: Replace any blades that cannot easily be balanced.
