4.8. REGENERATIVE DUMPING POSITION
Your valve is equipped with a regen position in the bucket circuit. When digging with the loader, feather the single
handle controller outward to angle the bucket forward and put the weight of the tractor on the cutting edge. If you
position the loader valve into regen position, weight of the tractor may not remain on the cutting edge. The loader
valve has a “Regenerative Spool” incorporated in the bucket spool. The tilt cylinders must be connected to this
spool allowing the operator to choose normal dump or fast dump during loader operation. While using regen
position some oil will bypass over relief which could cause a small amount of hose chatter and hydraulic relief
noise which is normal to operation.
NOTE: Regen position will speed up dump operation in most applications. However, operator may not see
significant speed increase at high RPM due to some oil being forced relief. Use of regen position will
eliminate bucket cylinder cavitation.
NOTE: Use normal dump position when digging with loader. This will allow operator to put full tractor
weight on cutting edge during this operation. The regenerative function can then be used when dumping
load from bucket.
NOTE: Valve circuits must be hooked up correctly to allow regen to operate correctly.
IMPORTANT: If the bucket or attachment does not operate as indicated on the directional decal, lower the
bucket to the ground, stop the engine, and relieve all hydraulic pressure. Recheck hydraulic circuit
hookup to loader valve and correct.
NOTE: Use of regen function during dumping will eliminate attachment cylinder cavitation, which will
reduce or eliminate any free movement of bucket or attachment during loader operation.
CAUTION: Do not tamper with relief valve setting. The relief valve is pre-set at the factory.
Changing the setting can cause overloading of the loader and tractor, which may result in serious
injury.
IMPORTANT: If the bucket and lift circuits do not operate correctly check single lever controller pivot
position along with cable position.
4.9. INITIAL LOADER OPERATION
NOTE: Keep engine speed at low idle during the initial loader operation.
Before operating the loader, fully raise and lower the boom two or three times. Then raise the loader bucket
approximately four (4) feet above the ground and cycle the tilt cylinders two or three times. Lower the bucket or
attachment to the ground. Check the tractor hydraulic fluid level and fill as required. Refer to the tractor Operator
Manual for the proper hydraulic fluid and the correct hydraulic fluid level.
CAUTION: Before leaving the tractor seat, lower attachment or loader boom to ground, stop
engine, lock brakes, relieve hydraulic pressure, and remove key.
IMPORTANT: Always keep the cylinders in a retracted position when the loader is not in use to guard
against rust and contamination which may cause damage to the cylinder rods and hydraulic system.
