12’ DISCHARGE AUGER
Transport Cradle
The unloading auger must always be moved to and set into the transport cradle before the mixer is
transported. If the auger does not set in the cradle, adjust the stop bolt on the vertical rotating auger at
the rear of the machine.
ADJUSTMENTS
TANK LID
The tank lid on top of the mixing tank is designed to be self-
unlatching in the event that the mixing tank accidentally becomes
overfilled. The latching mechanism should be properly adjusted by
the latch nut to maintain proper tension on the lid to keep it closed
and weather-tight, but still allow it to be forced open from the inside
of the tank by overflowing material. If the latch handle can be pulled
straight up approximately ½” (12 mm), completely compressing the
spring, tension is correct.
IMPORTANT:
The latch springs should never be completely
compressed when the handle is all the way down or the lid will not
open during over filling.

3’ & 6’ Discharge Auger Extensions
The 3’ and 6’ discharge auger extensions fold back and lock into position with a safety lock pin. If the
main pin does not line up with the hole on the bracket of the standard 12’ auger, loosen the bolts and
adjust the bracket.
NEEDLE VALVES
An adjustable needle valve is provided on each hose of the discharge auger rotation to control the speed
of auger swing to provide smooth rotation. Needle valves are located at the rear of the machine by the
hydraulic rotation motor. Unlock the set screw on the valve - adjust each valve by dialing it left or right to
decrease or increase auger rotation speed. After the speed has been set, lock the set screw down.
DRIVE CHAIN
Chain tension is self-adjusted by a spring-loaded idler and requires
very little adjustment. there should be approximately an 1/8” gap
between the spring coils for proper tension. The chain, sprockets,
and spring should all be inspected periodically for signs of wear.
