5.2.3 VALVE MANUAL OVERRIDES
WARNING!
Manually over riding valves should only be done in an emergency, or when troubleshooting and not in normal
operation. Some valves when manually overridden will cause mixer functions to move, so ensure other
equipment and personnel are out of harms way before attempting to over-ride a function manually.
Cartridge Valves:

Remove acorn nuts to get access to the manual override
hex adjustment using a 1/2” wrench.

Loosen locknut before attempting to adjust override
adjustment.

Using a 4mm Allen key turn the override adjustment screw
in CW until function movement begins, or adjustment is far
enough for desired speed / diagnostics.

Once testing is complete ensure override adjustment is
turned all the way out CCW until it stops. If the override is
left in even a little bit the function may creep or go into an
alarm once in normal operation.

The mixer is designed to control these valves electrically
only unless in an emergency.

Ensure locknut is hand tight and acorn nut is replaced.
Sectional Valves:

To manually override the mix auger section, use a small
Allen key and push down on override pin . The more you
push down the faster the auger will turn.

To manually override the boom, chute, or swing functions
push in on override pin .

Do not loosen locknut or attempt to adjust the bias
screw in or out. This is factory set and will affect function
performance if adjusted incorrectly.
INFORMATION
There is more detailed information when to use manual overrides for
individual functions in the following sections. Manual overrides should
only be used when electrical diagnostics have not shown any issues and
as a last resort.
