process 8 to 12 pounds of meat per minute. It consists of a 1 HP drive assembly with a No. 12 drive hub
operating at 250 RPM, a grinder head assembly with interchangeable plates to vary the texture of the
processed meat, an 8 quart feed pan to hold the meat that is to be processed, and a stomper to push the
meat into the grinder.

ASSEMBLY INSTRUCTIONS

Attach the pan support (Figure 1 [6]) to the housing cover using two 10-32 pan head screws. The PTO
adapter (Figure 2) should remain on the PTO drive shaft when the grinding head is removed. The com­ponents of the grinder assembly should be washed with a warm water and mild soap solution and dried
prior to use. Inspect the knife (Figure 4 [6]) for sharpness and handle it with care.

Remove the PTO cover cap. Insert the grinder housing (Figure 4 [4]) into the PTO hub of the drive
unit. Align the pin in the grinder housing with the hole in the PTO hub and push the grinding head fully
into the PTO. Tighten the thumb screw to secure the grinder head to the PTO.

Lightly coat the drive shaft and fiber washer of the worm assembly with Petrol-Gel. Insert the worm
assembly into the grinder housing aligning the square shaft end with the PTO adapter and fully engaging
it in the PTO adapter.

The knife (Figure 4 [6]) and grinder plate (Figure 4 [7]) should be coated with Petrol-Gel or beef
tallow prior to assembly. Place the knife, sharp edges facing out, on the square extension of the worm
assembly. Place the grinder plate on the pin in the end of the worm and into the grinder housing aligning
the notch in the plate with the pin in the grinder housing. Screw the ring (Figure 4 [8]) onto the grinder
housing using only minimum force. The ring controls the pressure between the plate and the knife. The
knife is easily damaged by running dry or excessive force on the ring.

Insert the spout on the feed pan into the throat of the grinder and rest the pan on the pan support
bracket on the drive unit.

OPERATING INSTRUCTIONS

Choose a location for the MG8912 that is convenient for the operator, allowing free access to the

power switch and sufficient clearance for safety and care of operation.

Slice the meat into strips which will easily fit into the throat of the grinder.

Place a suitable container at the discharge of the grinder.

Place the meat in the feed pan and start the grinder.

Hand feed the meat into the grinder. DO NOT place fingers inside the throat of the grinder, use the
stomper to push the meat into the worm. Do not use the stomper to force feed the meat into the
grinder at an increased rate. Best results are obtained when the meat is fed only as fast as the grinder
processes it.

Switch the power “OFF” when processing is interrupted.

When the processing has been completed, switch the power “OFF” and disconnect the power supply

cord.

Dismount the grinder from the drive unit and disassemble, wash and dry the components of the

grinder.

Store the components in a refrigerator for added sanitation.
