Adjusting the Clearance Between the Blade Frames
WARNING
ALWAYS DISCONNECT THE SLICER FROM THE POWER SUPPLY BEFORE
ATTEMPTING ANY TYPE OF MAINTENANCE TASK.
The distance between the blade frames is adjusted by rotating the eccentric pins located
above the blade frames. Two wrenches are used to do this. One wrench is used to
keep the eccentric pin from rotating while the second is used to loosen the lock nut on
the end of the pin. This nut secures the pin in position once its proper location is
determined. See the illustration below.
To adjust the eccentric, once the lock nut is loosened, rotate the pin using a wrench,
rotating the pin, (it is possible that both pins will need adjustment at the same time), until
the knives of the machine are in line, (alternating blades should not appear to be in front
of or behind each other when viewed from the side). A straight edge may be used from
the dull side of the knives to aid in determining if the knives are in line. When the
eccentric pins are in the desired position tighten each of the locknuts to secure the
position of the eccentrics. Check the blade frame clearance by turning the driven pulley
by hand. Two things may happen if the knives are not inline, the blade frames may hit
each other causing a loud knocking noise or the cutting efficiency of the machine may be
greatly reduced.
