2. Remove any remnants of the broken shear

pin. It may be necessary to unscrew the

nut from the broken shear pin and drive

out the broken pin.

3. Insert a new shear pin through the hole in

the auger shaft and tighten using the

shear pin nylon locknut. Do not over-

tighten the nylon locknut.

DRIVE SPEED CONTROL CABLE ADJUSTMENT

WARNING! Entanglement Hazard – Use caution when performing the speed

control cable adjustment.

The speed control lever is connected to two cables that work in tandem to

control machine speed and direction. As the speed control lever is moved from

forward to reverse gears, one cable is pulled and one is pushed (Fig. 10).

Depending on if the cable setting towards

forward or reverse, adjustment of the

cables will vary.

To adjust the cables, one cable should be

moved up and the other down equally in

their respective brackets until there is a

positive direction change when the lever

is shifted between F1 and R1. The middle

position between these two settings is

neutral (there is no actual neutral

‘notched’ position on the control panel).

1. With the engine running engage the drive control handle and move the

speed control lever between 1 and R1 to determine which way the cables

need to be adjusted. Release the drive control handle when shifting

between gears.

2. Loosen the jam nuts on each cable (only one or two threads) and move

each cable up and down as required until a positive direction change is

achieved when the lever is shifted between F1 and R1. This may take

multiple attempts to find the exact setting.

3. Tighten the cable jam nuts once the proper setting has been achieved.
