The Feed Roller Lift option uses a hydraulic cylinder to lift, lower
or apply down pressure to the top feed roller. The lower feed
roller is fixed.
The lift feature can be useful when feeding in large end-cut
material that the roller has difficulty climbing over. Lift the roller,
start the material then release the roller to begin feeding.
When feeding in extremely curved or bushy material, use the
cylinder down force to hold and help grip the material as it is fed
through.
• Push the control valve lever forward
to raise the top feed roller. Push it all
the way forward into the detent and
the cylinder holds the feed roller up
while you feed in large material.
• Pull the valve lever back to lower
the top roller or apply down force to
the top roller. Release the lever and
it returns to its neutral position. The
cylinder then remains stationary and
stops applying down force to the
roller.
For servicing purposes or clearing a jam, lock the upper feed
roller in the raised position by engaging the cylinder locking pin.
