Inspect the blades periodically for wear or damage.
Use care when checking the blades. Wrap the
blades or wear gloves, and use caution when
servicing the blades. Only replace or sharpen the
blades; never straighten or weld them.
On multi-bladed machines, take care as rotating
one blade can cause other blades to rotate.
Replace worn or damaged blades and bolts in sets
to preserve balance.
Park the machine on a level surface, disengage
the blade-control switch, and engage the parking
brake.
Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
Inspect the cutting edges
If the edges are not sharp or have nicks, remove
and sharpen the blade; refer to
Blades (page 67).
Inspect the blades, especially in the curved area.
If you notice any cracks, wear, or a slot forming
in this area, immediately install a new blade
