777-NT Variety Slicer 

0777S20039  

6-8 

 
Replacing the Belt 
 

Remove the infeed table, crumb chute, and discharge table.  First remove the four black 
knobs securing the tables, (see the illustration below).  In addition to the knobs the 
infeed and discharge tables are held in place by friction so pull the infeed table straight 
out and hard to separate them. 
 
Turn the adjustment nut, at the lower end of the motor mounting plate, counterclockwise 
with a wrench to loosen the drive belt, see “Tightening the Belt” above. 

Disconnect the end of the connecting rod at the rocker by removing the two cap screws 
and cap as shown below.  The drive belt may now be removed from the pulleys
