stop in the required time, check and adjust belt
tension. Inspect belt frequently for signs of excessive
wear. Observe drive belt for slippage due to wear
when operating machine. If slippage does occur
adjust as follows.

position to full extended position. Move control
lever against handle. Measure the overall length of
the spring. The length of the cable spring should
increase by 1/2" to 3/4" when the clutch control is
depressed. See Figure 4.1.
