STEP 10: INSTALL GRINDER RING
(Fig. 24 )
CAUTION: All threads must be cleaned and
lubricated with U.S.D.A. (or equivalent) approved
grease or mineral oil before installing ring onto
grinder head. Dirty threads will cause incorrect
plate/knifeholder spring tension and will result in
poor cutting action.
Place ring onto head. Hold pressure against the
ring as you turn CLOCKWISE. If threading does
not occur, reverse direction, still holding pressure
until the ring “jumps” a thread. Then thread on
clockwise, all the way.
Using the ring wrench or ratchet lever, turn the ring
on as far as it will go without forcing then unscrew
counterclockwise 1/8 turn.This will shift the
plate notch up against the supporting side of the
plate lug in the head, which will prevent premature
wear of the plate lug.
NOTE: The only exception to this tightening
method is when using a teardrop or round hole
plate with holes larger than 1” (25mm) diameter.
Then snug the ring onto the head HAND TIGHT
ONLY.
DO NOT FORCE THE RING ON. IF BINDING
OCCURS, REMOVE THE RING AND CHECK

MANUAL FEEDING (Fig. 30 )
WARNING
Manual feeding (hand−feeding) can
pose potentially dangerous situations.
Keep hands out of the feed hopper at all
times. Do NOT poke around in the feed
hopper with forks or rakes while the
grinder is in operation.
STOP THE GRINDER and LOCK OUT
MAIN POWER WITH A PADLOCK
BEFORE ATTEMPTING TO CLEAR THE
HOPPER.
If manual feeding is necessary for purposes of
inspection or other reasons, the product should be
gathered on a feed table. Use a fork or rake to feed
the product into the hopper at a steady rate and
from a safe distance. Make sure all appropriate
safety measures are taken. Refer to General Safety
Information on page 3.
KEEP FEED SCREW COVERED (Fig. 30 )
Keep the feed screw slightly covered with product
at all times to maintain efficient grinding.

off and lock out power with a padlock. Refer to
General Safety Information on page 3.
a. A dangerous situation exists or is
imminent.
b. Something other than product enters the
hopper.
c. Output slows down or product stops
coming from the grinder.
d. Associated take−away equipment has a
malfunction.
e. Drive belts begin to squeal or when other
maintenance must be performed to resolve
a problem.
LOCK OUT
WITH A
PADLOCK
Fig. 32 Shut Off and Lock Out Power with a Padlock.
WARNING
In all cases, after stopping the grinder,
shut off and lock out main power with a
padlock before trying to resolve the
problem.
NORMAL SHUT−DOWN
a. For Thawed & Tempered Meats and Other
Soft Products. The grinder can be stopped
at any time providing a re−start with
product in the feed hopper will not tax the
motor beyond the manufacturers’
specifications.
b. For Hard−Frozen Meats, Bones, Hides and
Other “Tough” Products. Except for an
emergency, stop the grinder only after all
of the product has been ground out of the
grinder, or when discharge ceases. If the
grinder is stopped under load, a re−start
may be difficult, or entirely impossible.
WARNING
Frequent starts in quick succession
may damage the drive or the motor, and
will subject the grinder to unnecessary
wear and tear.
