system required for some applications. While
running at the FAST speed position, the flywheel
brake MUST stop the engine within three
seconds when the operator releases the
equipment safety control.
Test Brake Torque
1. Disconnect spark plug wire.
2. Remove static guard/rewind assembly.
3. Unscrew and remove fuel tank.
4. Remove dipstick and oil fill tube.
5. Unscrew and remove blower housing.
Figure 1 - 13
6. Using a torque wrench ( A , Figure 1-13)
and socket to fit the flywheel nut, turn
flywheel clockwise with brake engaged.
While turning at a steady rate, torque
value should be 26 lb.-in. (3 Nm) or higher.
7. If reading is low, check thickness of brake
pad ( B ). Replace brake assembly if
thickness is less than 0.090” (2.28mm).
8. If brake pad thickness is acceptable,
adjust control cable to position pad closer
to flywheel when safety control is in RUN
position.Repeat Step 6.
9. Replace brake assembly if correct
adjustment cannot be made.
