7.5. TRACTOR REMOTE VALVE EQUIPPED WITH
2 OR 3 CONTROL HANDLES
7.5.1. Tractor remote valve equipped with 2 or 3 control
handles will function as described at right.
7.6. NEUTRAL POSITION
The loader external valve provided by KMW has a “neutral
position” which prevents movement of the loader or
attachment. When the control handle is manually released
from the work position, the valve spool will return to the neutral
position.
7.7. FLOAT POSITION
7.7.1. The loader external valve provided by KMW has a “float position” incorporated into the lift cylinder circuit
which allows the loader to float. This float feature is important for satisfactory operation when scraping, sweeping,
leveling, or any job where it is necessary to follow the contour of the surface. To activate the float position, lower
the bucket or attachment and push the control handle all the way forward into detent. The valve will stay in float
detent position until the operator manually pulls the control handle out of detent position to deactivate float.
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.
7.8. REGENERATIVE DUMPING POSITION
Your valve is equipped with a regen position in the bucket circuit. When digging with the loader, feather the loader
valve control handle 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 attachment 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 over loader valve 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.
