TROUBLESHOOTING

If your unit fails to operate, contact LEM Products technical assistance Toll Free at 877-536-7763. If meat is mashing instead of extruding in strings from the grinding plate, chill the meat to 40°, and check to see that the plate and blade are properly installed, check that the washer is installed on the back of the auger. A dull knife or plate will also cause mashing of the meat.

For an overheated plug or grinder housing discontinue use and contact technical assistance Toll Free at 877-536-7763. This product is equipped with a polarized AC (Alternating Current) plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. (If the plug does not fit fully into the outlet, contact a qualified individual to install the proper outlet.)
DO NOT DEFEAT THE SAFETY PURPOSE OF THIS POLARIZED PLUG IN ANY WAY.

CAUTION

  • Before using the device for the first time please make sure to read carefully and thoroughly through these operating instructions and the safety advice.
  • Familiarize yourself completely with the functions of the appliance.

OPERATING INSTRUCTIONS

GRINDING

When making burger from wild game we suggest adding a minimum of 10% pork fatto the meat. This will give the burger moisture, but still not make it fatty. Cut meat into strips that will easily fit into the throat of the grinder head. Meat should be 40° or colder and free of bone, gristle and sinew. Feed meat slowly into the throat of the head. Use the meat stomper to push meat into the throat of the head. Allow grinder to do the work. Do not force meat.

NEVER USE FINGERS TO PUSH MEAT INTO THE HEAD

Place meat into freezer for 15-20 min. Grind meat through the coarse plate first. Return meat to freezer. Turn motor off and unplug the grinder. Remove the coarse plate and clean the head of sinew, fat or gristle that has accumulated during the first grind. Assemble the unit with the fine plate, plug grinder in and regrind the meat.

SECOND GRIND

It is highly recommended to place ground meat into the refrigerator or freezer for 15-20 minutes prior to second grind. Turn on the grinder (make sure to have a clean and meat free head/throat). Feed the ground meat into the head/throat slowly. Do not pack the throat full of meat. Keep the throat clear of meat. Resist the urge to stomp or push the meat faster than the auger can move it.

CLEANING

  • Unplug grinder and disassemble the grinder head. Wash all parts in hot, soapy water and thoroughly rinse in hot water.
  • Dry completely. Spray parts with food-grade silicone (Available at LEM Products) to prevent rust and keep your grinder in like new condition.

STUFFING SAUSAGE WINGS

There are several methods for stuffing sausage with your grinder. Before you begin, review the helpful tips listed below:

  • When making sausage, use at least 20% fat with your meat and grind it like burger. Without adequate fat, your sausage will be dry when cooked, and will tend to crumble when cut or sliced.
  • Make sure the meat is well-chilled (28-32° F).
  • Use only the finest natural casings- hog for large sausages and sheep for small, breakfast-style links. Soak and rinse well before use. Eddible collagen casings are a nice alternative without the prep.
  • Slide casings onto stuffing tube making sure to leave the end of the tube open. Turn grinder on and feed meat into the head until meat is at the end of the stuffing tube. Stop grinder and pull casing out past the opening of stuffing tube about 1”. Twist, knot or clip casing closed. Restart grinder. This procedure will keep the casing from filling up with air when you first start stuffing. Continue to feed meat into head until the casing is filled.
  • Stuff the casing firm, but not to the bursting point. To divide the sausage into links, give the casing two or three quick twists before adding more meat. Twist links in alternating directions (clockwise for the first, counter-clockwise for the second) to ensure that they keep their forms.
  • If air bubbles form in your sausage, you can pop them with a sharp, sterilized needle.

CAUTION

  • Before cleaning, assembling or disassembling meat grinder, make sure the grinder motor is OFF and the plug is removed from the outlet/power source.

GRINDER ASSEMBLY

BEFORE USE: WASH ALL PARTS OF THE HEAD ASSEMBLY IN HOT SOAPY WATER. THIS WILL REMOVE ANY GREASE RESIDUE AND DIRT LEFT FROM THE MANUFAaURING PROCESS DO NOT PUT PARTS IN DISHWASHER.

SEE DIAGRAM

  1. Remove the Retaining Ring (#1), Grinding Plate (#5), Knife (#8), and Auger (#9) from the grinder head (#12). Be sure that the Star Bolt (#15) on the side of the motor coupler is backed all the way out. Insert the grinder head into the motor coupler so that the auger fits properly into the Main Gear (#21). The head should be positioned upright so that the locking screw can be firmly tightened to hold it in place during operation.
  2. Place Washer (#10) on back of Auger Drive.
  3. Insert Auger (#9) into grinder head and turn until the auger slips into the shaft of the motor.
  4. Place the knife (#8) on the square Auger Stud (#11) of the Auger (#9) with blades facing out.
  5. Place Grinding Plate (#5) on auger stud in front of knife. Make sure notch in plate is on locating pin in head. Cutting edge of knife should be facing and flush against the grinding plate.
  6. When assembled, plate will stick out past the end of the head by 1/8″- 3/16”.
  7. Screw Retaining Ring (#1) onto head until tight. Hand-tighten, do not over-tighten. Over-tightening will cause undo wear on the knife and plate of the grinder.
  8. Insert Meat Pan (#14) into grinder head securely and snap pan holder on to handle.
