1.11. The switch should not show continuity when the
plunger is pressed. See Figure 1.11.
NOTE:
“OL” meter reading in Figure 1.11 indi-

INSPECTION OF THE DRIVE SYSTEM
2.1.
Begin with an operational test. Does the drive
system operate over the full range of speeds?
2.2.
Remove belt cover using a 3/8” wrench.
See Figure 2.2.
2.3.
Inspect variable speed pulley for full movement.
Run the self propel mechanism though its full
range of speeds. See Figure 2.3.
•
The crankshaft must be turning for the variable
speed mechanism to respond to the control
lever.This can be done with the engine running
or by pulling the engine through manually.
•
The belt and pulley system operates whenever
the engine is running. The variable speed func-
tion can be tested without pulling up the self-pro-
pel bail to engage the clutch.
