Blade Maintenance
Blade Safety
•
Inspect the blade 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.
Checking for a Bent Blade
After striking a foreign object, inspect the machine
for damage and make repairs before starting
and operating the equipment. Torque all of the
spindle-pulley nuts to 176 to 203 N∙m (130 to 150
ft-lb).
1.
Position the machine on a level surface, raise
the cutting unit, engage the parking brake, put
the traction pedal in
in the O
position, shut off the engine, and
FF
remove the ignition key.
Note:
Block the cutting unit to prevent it from
accidentally falling.
2.
Rotate the blade until the ends face forward and
backward and measure from the inside of the
cutting unit to the cutting edge at the front of the
blade
(Figure
Note:
Remember this dimension.
3.
Rotate the opposite end of the blade forward
and measure between the cutting unit and
cutting edge of the blade at the same position
as in step 2.
Note:
The difference between the dimensions
obtained in steps
