This guide covers installation, daily use, cleaning and basic troubleshooting for Eurodib spiral mixers, planetary mixers and dough sheeters. Always follow the manufacturer's manual for your model and have a qualified, licensed installer handle electrical and gas connections.

## Key takeaways

- Always disconnect power before cleaning or servicing any Eurodib mixer or sheeter.
- Use only the recommended batch capacities from the model's manual to avoid overload and motor damage.
- Clean bowls and agitators after each use with hot water and mild soap; M Series bowls and accessories are not dishwasher safe.
- For electrical or gas installation, hire a licensed professional to meet local code; the machine must be properly grounded.
- Contact the manufacturer's authorized service network for repairs beyond the basic troubleshooting steps in the manual.

## Which manual covers which model

Eurodib provides a separate operation manual for each equipment series. The LB Series manual covers the LB20T, LB30T, LB40T, LB50T and LB60T spiral mixers. The LM Series manual applies to the LM20T, LM30T, LM40T and LM50T floor pizza spiral mixers. The LR-GM Series manual is for the large LR-GM25B, LR-GM50B and LR-GM75B spiral mixers. The M Series planetary mixer user manual covers the M10ETL and M20B and the M30AETL and M40AETL. The P-Roll rolling machine user and maintenance manual covers the P-Roll 320/1+, 320/2+, 420/2 RP+ and related sheeters.

This guide references those manuals. Always keep the correct manual near the machine and ensure all operators have read it.

## Installation requirements

All Eurodib mixers and sheeters must be installed by a qualified, licensed professional. Electrical and gas connections must comply with local codes. The LB Series manual warns that the machine must be grounded properly and that the user's power supply must include a ground wire. The LM Series manual states that a competent person must carry out the electrical installation in accordance with local or national electricity board regulations.

Position the mixer on a horizontal, stable floor that can support the weight of the machine and a full bowl. The LM manual recommends setting the mixer at a height where the bowl handles are between knuckle and elbow height to reduce bending. The LR-GM manual describes fixing the machine in place using the two directed casters, one mecanum wheel and four regulating screws; after confirming the location, screw in the regulating screws to hold the machine firmly.

No universal clearance dimensions are given across all manuals. The LM manual advises ensuring sufficient space around the mixer for safe operation and that service access on the top, side and rear are clear. For specific clearance requirements, refer to the installation section of the manual for your model.

The video 'EURODIB LR-GM25/50/75 \| Wheel & Guard Installation Guide' demonstrates the step-by-step process for installing the wheel and guard on LR-GM25, LR-GM50 and LR-GM75 models. It shows the unboxing, required tools and installation procedure.

## Daily operation and controls

Each series has distinct controls and operating steps. The following summaries are based on the manufacturer's manuals.

- LB Series spiral mixers: The control panel has a Start button, Stop button, Speed control button and Timer button. Open the protective cover, add flour (do not exceed the maximum capacity for your model), then add water equal to 45–50% of the flour weight. Close the cover, start the machine and mix for approximately 8 minutes. Press the Stop button, open the cover and remove the dough. Never put hands or hard objects into the bowl while the machine is running.
- LM Series spiral mixers: Operation is similar. The LM manual lists mixing speeds of 202 r/min for the hook and 16 r/min for the bowl. Capacities: the LM20T handles 5 kg dry flour (11 lbs), the LM30T 8 kg (17.5 lbs), the LM40T 10 kg (22 lbs) and the LM50T 12 kg (26.5 lbs). Always close the protective cover before starting.
- LR-GM Series spiral mixers: These have a control panel with low-speed and high-speed timers, a power light, manual/automatic mode selector, Start, Stop and emergency stop buttons. You can set the duration of low- and high-speed operation up to 120 seconds each. In automatic mode, the mixer runs at low speed for the set time, then high speed for the set time and stops. The manual warns not to load the bowl over the specified capacity limit; for the LR-GM25B the flour mixing capacity is not more than 25 kg, for the LR-GM50B 50 kg, and for the LR-GM75B 75 kg. When mixing steamed bread or noodles, use only 80% of the listed maximum.
- M Series planetary mixers: The M10ETL and M20B have a Stop button, Start button, speed lever, safety guard and bowl lever. The M30AETL and M40AETL add a pulse button and attachment hub. To operate: rotate the guard back, lower the bowl support, place the bowl and lock it, attach the desired accessory (spiral, beater or whisk) by turning it clockwise onto the centre pole, add ingredients, raise the bowl, close the guard, select the speed with the speed lever and press the green Start button. Stop with the red button and wait for the mixer to come to a full stop before lowering the bowl. The manual provides a capacity chart: the M10ETL and M20B are not suitable for bread or pizza dough; the M30AETL can mix bread dough with 17.5 lb flour (8 kg) yielding 13.5 kg dough at 70% hydration, and pizza dough with the same flour weight at 60% hydration.
- P-Roll dough sheeters: The PLUS version adds a pedal control: with the pedal switch at O the machine does not start, pressing the pedal starts the rollers, and lifting your foot stops them. Adjust the roller gap with the knob. The dough must be lightly dusted with flour and risen for at least 6–8 hours. Squash the front edge into a wedge and feed it into the top rollers. The top rollers flatten the dough into an oval; on models with a rocker (32/2, 42/2), the dough rotates 90° and passes through the bottom rollers. On the 42 RP version, you must manually rotate the dough 90° and feed it through the second set of rollers. The manual cautions to run the dough through the rollers only once, otherwise it may break up and become sticky.

## Cleaning and routine care

All Eurodib manuals stress that you must disconnect the machine from the power supply before cleaning. The M Series manual says to clean the mixer daily using mild soap and water. Do not use scouring powder, scouring pads or abrasive cleaners.

For spiral mixers (LB, LM, LR-GM), clean the bowl and agitators after each use. The LB manual advises lubricating chains and main moving parts about once a month, checking belt and chain tension every six months, and inspecting the electric circuit once a year. The LM manual gives the same lubrication and inspection schedule. The LR-GM manual's schedule includes adjusting the conveyor tension every two months.

For M Series planetary mixers, the bowl and accessories are not dishwasher safe. Wash them with hot water, mild soap and a soft bristle brush. The guard assembly can be removed for cleaning: lower the bowl, remove it, loosen the front screw with a screwdriver, take off the cage, clean it and reassemble.

For P-Roll sheeters, clean after every use. Remove the guards, slides, scrapers and springs, and open the rollers fully. Use a brush to remove dough and flour residues, then clean all parts with a sponge or cloth, water and neutral detergent. Rinse thoroughly, dry with food-safe paper towel, and wipe with a disinfectant for food processing machinery. The PLUS version has an AISI 430 ceramic coated slide held by magnets for easy removal. Lubricate the shafts and rollers once a year with paraffin oil, following the disassembly steps in the manual.

## Basic troubleshooting

The manuals include troubleshooting tables for common issues. Always disconnect power before inspecting the machine, unless the troubleshooting step requires the mixer to be energized—in that case, use extreme caution and only qualified personnel should proceed.

For LB and LM spiral mixers: if the machine cannot start, check that the electrical connections are tight and the protective cover is fully closed. If the safety switch does not work, inspect the press plate of the safety switch and its circuit. If the machine temperature is too high, the working time may be too long, the supply voltage may be low, or the bowl may be overloaded. Low mixing efficiency can be caused by worn transmission parts or loose belts and chains; tighten or replace them.

For LR-GM spiral mixers: if the machine stops suddenly and the indicator light flashes, the bowl has been overloaded. Turn off the power, open the electric box cover, press the reset button and remove the excess dough. If the power light does not illuminate, the bulb may be burnt out or the power line disconnected. If the mixer does not start when the Start button is pressed, check that the emergency stop button is reset (rotate clockwise) and that the protective cover is correctly positioned.

For M Series planetary mixers: if the mixing pole does not rotate, verify the power cord and connections, and ensure the accessory is locked by turning it clockwise. Oil leakage indicates worn oil seals; have them replaced. A tight bowl lever may be corroded or dry—clean and oil it. If the motor temperature is high, check the supply voltage, reduce the ingredient load to match the recommended capacity chart, and confirm the correct speed and accessory are selected.

For P-Roll sheeters, the manual says that if the machine is malfunctioning, do not use it and contact an authorized service centre immediately.

## When to call for service

All Eurodib manuals state that repairs must be performed by qualified technicians or authorized service personnel. The LB manual says repairs need an expert using original spare parts. For any issue beyond the basic troubleshooting steps above, contact the manufacturer's authorized service network.
