Allied Front-End Loader
- 12 - P4493
All Buhler-Allied hydraulic valves are self-centering and return to neutral from all
positions except float. The float or detent spool is only to be used on the boom
circuit. This position allows the oil to freely flow through the valve so the lift
cylinders can extend or retract. It can be engaged by slightly pushing control
beyond full lower. Float will allow for the loader to lower and rise as the
attachment follows the ground contours. To disengage float, slightly pull control
back towards the neutral position. The Allied Remote Hydraulic Control can be
locked in the neutral position to minimize unintentional movement.
CAUTION Lower and dump heavy loads slowly by feathering.
Stop tractor movement gradually. Never drop a loaded attachment and “catch”
hydraulically. Stopping with such downward momentum may cause damage to
the loader or tractor.
When handling heavy loads be sure to raise and lower the loader slowly while
leveling the attachment as required. Feathering can assist in accurately
controlling operations by regulating oil flow through cylinders.
A third function hydraulic control is available for grapple or other hydraulic
applications. An optional divertor valve is connected to the loader attachment
spool and is operated via the Allied Remote Hydraulic Control momentary switch
and simultaneously engaging the bucket spool through dump or rollback.
Bucket:
When loading a bucket, approach straight
and enter the pile with a level bucket parallel
to the line of motion.
IMPORTANT: Attempting to turn while
loading may cause damage to the loader or
tractor.
Work controls to raise and rollback the bucket
simultaneously. The combined actions of lift
and bucket cylinders increases loading
efficiency and minimizes resistance to lift.
NOTE: On tractors with low hydraulic oil
flows, both functions may not be possible
