SERVICE
If the brake system fails to kill the ignition and stop the blade within 3 seconds the following service procedures
should be followed.
FLYWHEEL REMOVAL
NOTE: BEFORE THE FLYWHEEL IS REMOVED OR REPLACED, THE BRAKE PRESSURE ON THE FLYWHEEL
MUST BE RELIEVED AS OUTLINED BELOW UNDER "BRAKE LEVER AND PAD".
Remove the flywheel as outlined in Chapter 9 under "Disassembly".
BRAKE LEVER AND PAD
Bottom Surface
UNHOOK TORSION SPRING
To relieve the brake pressure on the flywheel, remove
the torsion spring by firmly grasping the short end of
the spring with a pliers and unhook the spring from the
bracket then remove the flywheel (diag. 6).
Remove the brake lever and pad assembly. Inspect the
brake pad for dirt, oil or grease contamination. If the
pad is contaminated, or if there is less than .060" (1.524
mm) of brake pad material at the pad's thinnest point,
replacement is necessary. The brake pad is bonded to
the brake lever and must be replaced as an assembly.
Install the brake lever and pad assembly and continue
to reassemble the brake system in the reverse order of
disassembly.
NOTE: WHEN REMOVING THE BRAKE BRACKET THE
TORSION SPRING MUST BE RELEASED BEFORE THE
TOP STARTER BOLT IS REMOVED OR THE THREADS
IN THE CYLINDER BLOCK WILL BE DAMAGED.

To relieve the brake pressure on the flywheel, compress
the spring by moving the lever toward the spark plug,
when the hole in the lever aligns with the hole in the
bracket, secure the lever with alignment tool 670298
then remove the flywheel (diag. 7). Remove the alignment
tool. Release the spring tension by unhooking the short
end of the spring from bracket with a pliers. Remove
the “E” clip from the brake pad shaft. Slide the pad lever
from the shaft and unhook the link. Inspect the brake
pad for dirt, oil or grease contamination. If the pad is
contaminated, or if there is less than .060" (1.524 mm)
of brake pad material at the pad's thinnest point,
replacement is necessary. The brake pad is bonded to
the brake lever and must be replaced as an assembly.
Rehook the link, install the brake lever and pad assembly,
install the "E" clip, rehook the short end of the spring
and continue to reassemble the brake system in the
reverse order of disassembly.
