Need help?

Do you have a question about the Panasonic MK-MG1300WTN and is the answer not in the manual?

This document is a service manual for the Panasonic Meat Grinder, specifically covering models MK-MG1300WTN, MK-MG1300WTZ, and MK-MG1300WTQ, as well as their MSG variants for specific regional markets (Qatar, UAE, Saudi, Kuwait, Russia, Ukraine, etc.). It provides detailed information for experienced repair technicians, emphasizing safety and proper maintenance procedures.

Function Description

The Panasonic Meat Grinder is designed for household use to process various types of meat. Its primary function is to grind meat efficiently using a motor-driven feed screw and a series of cutters and plates. The device is equipped with different cutter types to achieve various grind consistencies: Rough Grind (7 x 16 pcs holes), Middle Grind (5 x 30 pcs holes), and Fine Grind (3 x 78 pcs holes). It also supports Kubbe attachments for specialized food preparation, though these attachments are not included with all regional models (e.g., MK-MG1300WTQ for Russia).

Important Technical Specifications

The meat grinder operates on an AC power source, with voltage ranging from 220V to 240V at 50/60Hz. The motor power is specified between 220W and 240W. A crucial safety feature is the integrated circuit breaker, rated at AC250V 1.6A, designed to trip within 4.5 to 7.0 seconds in case of an overload, protecting the motor and user. The device uses a thumb-ler switch for operation. The power cord length is 0.9 meters.

The hopper, where meat is fed, is made of aluminum. The overall dimensions of the unit are 155mm (width) x 255mm (depth) x 214mm (height), and it weighs approximately 3.1kg. In terms of grinding capacity, the device can process BEEF at a rate of 1000 g/min and MUTTON at 650 g/min when using the Middle Grind Cutter.

Usage Features

The manual highlights several precautions for safe and effective use:

Meat Type: Users are cautioned not to grind excessively hard meat. If the grinder becomes stuck, forcing meat into it should be avoided to prevent damage.
Vibration: It's noted that the feed screw might vibrate during use, which is considered normal and not a malfunction.
Locking Knob: The locking knob should not be overtightened.
Cleaning: Some parts of the grinder are not suitable for dishwasher cleaning, requiring manual washing.
Intended Use: The device is strictly for household use.

The troubleshooting guide provides solutions for common operational issues:

Motor Interruption (Overload): If the AC motor is interrupted while feeding meat, it could be due to feeding too hard meat, too much meat at once, continuous use for too long, or the circuit breaker activating. Remedies include removing hard meat, reducing feed rate, adhering to specified operating times, and resetting the breaker.
Motor Failure to Start: If the switch is on but the motor doesn't start, potential causes are a broken power cord, poor lead wire terminal contact, a faulty switch, worn-out carbon brush, or a broken AC motor coil. Solutions involve replacing or repairing the respective components.
Feed Screw Failure to Turn: If the motor runs but the feed screw doesn't turn, it could be due to worn-out or damaged gears, or a worn-out or damaged feed screw. Replacement of these parts is recommended.
Noisy Operation/Slow Grinding: Excessive noise or slow grinding can be caused by a worn-out carbon brush, worn-out or damaged gears, or worn-out cutting blade or plate. Replacing these components will restore performance.
Unusual Motor Noise: Unusual motor noise might indicate foreign matter caught in the gears or worn-out/damaged gears. Removing foreign matter or replacing gears are the suggested actions.
Burning Smell from Motor: A burning smell from the AC motor is a serious sign, usually indicating degraded motor insulation, requiring replacement of the AC motor.

Maintenance Features

The service manual provides detailed instructions for disassembly and assembly, crucial for maintenance and repair:

Motor Housing Disassembly: Involves removing four screws, then the locking knob, and finally opening the motor housing.
Motor Set & Gear Box Disassembly: Requires pulling up the gearbox, removing two screws from the motor unit, detaching connectors from the motor unit, removing four screws, and releasing two rubber holders.
Switch Disassembly: Involves using a small screwdriver to push out a catch, removing the switch, desoldering a pin to detach wires, and removing the micro switch (with a caution to note the catches).
Switch P.C.B. Disassembly: Requires removing the switch cover (again, noting micro switch catches), removing a nut, and then removing the switch P.C.B.

The manual includes an exploded view and replacement parts list for each model variant (MK-MG1300WTN, MK-MG1300WTZ, MK-MG1300WTQ). This list details every component, from the plunger and hopper to various screws, gears, bearings, and the motor itself, along with their part numbers, descriptions, and quantities. Critical safety components are marked with a triangle (A), emphasizing that these parts must be replaced with manufacturer-specified parts to prevent hazards. The packing diagram illustrates how the various components and accessories (like Kubbe attachments, cutting plate, food pusher, grinder cap, and grinder head) are arranged within the packaging, along with the top and bottom cushions and the carton box.
