ADJUSTMENTS
ADJUSTMENT OF BELT TENSIONER
There are four maximum belt tensioners on the Big Vac. Two
control the tension on the belts on the blower housing, one
each on the finger reel and the thatcher reel. The proper
tension of the idler should be 12 to 15 as per the gauge (A)
on the side of the tightener. Over tightening the belt will
shorten the life of the belt and the machine may not perform
to the best of its ability. To adjust belt tensioner, loosen bolt
holding tensioner. Bring idler pulley tight to belts and turn
tensioner into belts to 15°. Tighten holder bolt.
CONTROL PANEL ADJUSTMENT ARM
On the right hand side of machine is the
adjustment lock arm, by lifting up you
can adjust the control panel by moving it
forward or rearward. Make certain that
the lock arm is locked back in place
after adjustment. For up and down ad-
justment loosen the four adjustment
bolts place the control panel to where
you want it and tighten the four bolts.
