SPEED CONTROL ADJUSTMENT (See Figure 21)

NOTE: When operating the unit initially or after replacing the belts, there will be little difference between the highest two speeds until after the belts have gone through a break-in period and have seated themselves into the pulleys.

If speed control adjustment is needed, adjust the speed control links as follows. (A 3/4" shim or suitable spacer is required.)

Start the engine.

Place the shift lever in NEUTRAL position.

Place the speed control lever in highest speed position.

Release the clutch-brake pedal completely, then slowly depress the pedal all the way (to park position). Hold the pedal in this position.

Turn the engine off.

After engine stops completely, release the clutch- brake pedal.

Remove the transmission cover by removing the parking brake knob, shift knob and two truss machine screws.

Disconnect the rear speed control link from the variable speed torque bracket by removing the cotter pin and flat washer.

Models 820 thru 829: Place the speed control lever in the first position.

Models 840 thru 849: Place the speed control lever in the second position.

Disconnect the front speed control link from the variable speed torque bracket by removing the cotter pin and flat washer.
