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
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.
Inside Edge
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.
IGNITION GROUNDOUT TERMINAL
Inspect the ignition kill switch grounding clip for proper
alignment and contact with the brake arm. Insure that all
electrical connections are clean and secure (diag. 8 &
9).
