DRIVE CHAIN
To adjust front drive chain, loosen jam nut turn nut on adjusting
rod (located at the right hand front side of spreader) clockwise.
There should be 1/2” deflection at the center of the drive chain.
Over tightening or too loose of a chain will result in excessive
wear on the bearing, chain and sprockets. Retighten jam nut.

ADJUSTMENTS
APRON SPEED AND BEATER CONTROL
One cable controls both the beater clutch and two speed
clutch. To compensate for wear or stretching of this cable,
adjust the turnbuckle behind shield at the front of the
spreader.
TWO SPEED CLUTCH
If clutch control yoke becomes worn, it may be necessary to adjust the high speed clutch so it engages
and disengages completely. Adjustment to compensate for this wear is made by sliding spring stop (A)
on control rod closer to the clutch engaging lever. Initial adjustment should be made as follows: Distance
(B) between spring stop and jam nut is seven (7”) inches. Distance (C) between jam nut and shifting rod
bracket is one-eighth (1/8”) inches. This distance may be achieved by adjusting the turnbuckle at front of
spreader.

WHEEL HUBS
To adjust wheel hubs, tighten the castellated nut on
the spindle to the point where there is no end-play
and a slight drag on the bearings. Replace the
cotter key with a new one of the correct size.
