MECHANICS MAINTENANCE
Every year a mechanic or service technician should perform the following inspection and
carry out the respective maintenance as required:
Warning: FOR SAFETY, TURN OFF SLICER AND DISCONNECT ELECTRICAL CORD.
1. BELT DRIVE - This drive features a multi-ribbed high performance belt for
long trouble-free service. Inspect belt for proper tension. If glazed or
belt wear-in and stretching. However, if additional tension is required, it may
be obtained by turning adjustment nuts (Fig. 3 [21]) clockwise on take-up rod
(Fig. 3 [26])
the compressed length of the spring should be approximately 7/8".
2. CARRIAGE - Check for free smooth operation of last slice device and for
smooth travel of carriage arm (Fig. 4 [23]). Check for excess backlash
between slide bearing (Fig. 4 [50]) and carriage slide (Fig. 4 [55]).
lash (clearance) required for smooth carriage operation is obtained when a
carriage striking and damaging the knife edge. Too little lash results in binding
and a loss of smoothness in carriage travel. Lash is adjusted by loosening
locknut (Fig. 4 [47]) and turning nylon tipped stud (Fig. 4 [48]) clockwise to
reduce lash and counterclockwise to increase lash. Tighten locknut while
holding nylon tipped stud stationary with a screwdriver so it does not move.
Grease only the side of the carriage slide (Fig. 4 [55]) on which this nylon
