• Physical tness.

User must be physically suited and trained by a competent person prior to the rst use. People with disabilities may only use the machine after prior consultation by qualied personnel and if necessary use with aids.

• Keep children and visitors away from the workplace. Children and visitors must reside in a safe area outside the working area. Make the workplace safe for children by shutting off the workshop, interrupt or shutting off the supply.

• Do wear appropriate clothing. Danger from rotating parts.

Wear tight-tting clothes. Drop scarves, rings, bracelets or other jewelry and garments, which can get caught in the moving parts. Wear safety footwear and watch for a non-slip oor. Wear

a hat/hair net that protect long hair. Avoid wearing gloves, which can get caught in the turning.

• Use personal protective equipment (PPE). Ear protection: Various materials can produce a higher noise level when turning. In these cases when working, wear ear protection.

Eye / face protection: When working with the machine always wear goggles. Always use a

full edged eye- or face protection. Normal eye glasses are usually only shock-resistant and

protective goggles protect only your eyes. A face protection protects eyes and face.

Respiratory protection: Various kinds of wood, exotic wood or other harmful substances,

as well as certain types of work such as cutting, grinding, drilling can produce dusts that are hazardous to your health. Get yourself appropriately informed. Therefore only use the machine in well ventilated rooms and wear respiratory protection (PPE). Also use a suitable dust

extraction and/or ltering of the circulating air.

• Do not work in wet and dangerous environment. The MIDI FU-350 wood lathe is intended for indoor use only. Protect the lathe from damp or humid locations. Do not expose the lathe to moisture. Provide adequate lighting and ventilation of the workplace. Avoid areas with explosive atmosphere. The non-observance of the rules can lead to warranty and guarantee loss.

• Keep the work area clean! Not cleaned workplaces and tables can cause accidents. Do not turn the machine on until all items (tools,

pieces of wood and such) have been removed of the lathe. Keep the immediate working area and the oor free from dirt and surrounding off-cuts. Accumulated sawdust are a risk of re and accidents.

• Fire protection

Take note of the re alarm and re-ghting facilities such as location and use of re extinguishers. Regularly remove the shavings inside the bench bed on the electric motor so that the motor continues to be provided with the necessary cooling.

• Take note of the electrical safety standards. Make sure the electrical installation where you connect the lathe is proper. Only use the supplied safety plug. Do not use extension cords. The used safety sockets must be fused with 16 amp. Disconnect the machine from the power supply before attempting any user maintenance or repair.

• In case of power failure, the workpiece is no longer slowed down. The phasing-out of the speed may take some time to complete.

• Avoid unintentional starting.

The lathe is electrically ready to use when you connect the safety plug to the operator-side socket. Use the switch on the mobile control box to switch on and off. After work ends, pull the plug out of the socket.

• Never run the machine unattended. Do only leave the machine when it turned off and stopped.

• Protective devices Leave existing protective device on their positions and keep them operable.

• Use the correct tools. Only use suitable tools or accessories for the turning work. Avoid an unnecessary load on tool. Hold the turning tool in good condition. Sharp and clean tools guarantee best and safe results. Also bring the tools in the right position to the workpiece.

• Never step on machine and tools. A tilting machine or accidentally touched incisive tool can cause serious injury.

• Remove adjusting key and wrench. Never leave the socket wrench in the chuck. The socket wrench can be thrown out by starting the chuck and cause serious injuries. Make a habit of making sure that any tool has been removed before switching on the machine.

• Cleaning the lathe. Turn off the lathe before cleaning and disconnect the mains plug. Use a brush to remove shavings and dirt.

• Attention at work. Focus on your operation. A distraction through talks or carelessness can lead to serious injuries. Always ensure a correct body posture and balance. Do not operate the machine when you are tired or

under the inuence of drugs, alcohol or medication.

• Check for damaged parts. Before you use the lathe or tools, carefully inspect them for damage. Make sure that these parts are in a proper condition and their intended function is guaranteed. Check the alignment and fastening moving parts. Defective parts can affect the operation and cause injuries. Damaged parts must be repaired professionally or replaced.

• Work on the lathe When turned off electric voltage, check the spindle by turning it by hand whether the workpiece can move freely. Check the workpiece to prevent a breaking out of parts of the workpiece during the turning. Keep in mind that hollow areas or wide cracks can still be liquid after hours when using adhesives, also Cyanoacrylate Superglue. They can then when turning, due to the centrifugal forces, get out and be thrown

towards the ying chips, therefore in the direction of the turner, and be a risk of injury or pose a health

hazard. Before starting the spindle, always check whether the correct speed is set. Use of lowest speed for new or non-circular workpieces. Do the turning with recommended speed (table g. 29). Never slow down outgoing workpieces by hand. Set the hand rest as close as possible (approx. 5-10 mm) to the workpiece. Turn the workpiece before each start by hand, to ensure that it runs freely. Turn off the lathe from time to time to adjust the hand rest.

4. Functional instructions

A Midi FU-350 lathe is a machine, that is generally used to edit cylindrical or prismatic timber workpieces.

Here, the workpieces with special xing between headstock and tailstock or using special jigs (chuck, face

plate, etc.) are clamped and driven by an electric motor. The machine is driven by the electric motor via pulleys on the spindle. The Midi has three speed groups (Translations) that you can choose. The ne tuning of the motor speed is done through a frequency conversion, which should be regulated over the potentiometer (short POTI) at the mobile control box so that you can adjust the motor speed continuously in the respective group speed. This will help you to choose a reasonable peripheral speed according to the workpiece diameter. This improves the security when turning and the quality of the workpiece surface.

To turn on the drive unit, rst connect the plug of the Midi in the operator’s existing grounded socket. Turn

on the motor on the mobile control box (Fig. 2) and adjust the motor speed slowly up on the potentiometer.

Automatic shutdown

The Midi is equipped with a zero-voltage switch, which switches off the bench during a power outage and prevents a restart if the power supply is restored. If overloaded, the speed can be switched off by the frequency converter while turning. To be able to take the lathe back into operation in all cases, the cause must be eliminated. During a power failure the power supply shall be restored, when lifting the cover it shall be closed again and when overloaded it shall be reduced or the pulley with the lower speed indication shall be chosen.

By means of the hand rest the turning chisel will be guided to the workpiece by hand, which entails a risk of injury, since the cutting forces must be absorbed by the operator.

In order to derive the resultant forces, the turner knifes must continually lie rmly on the knife support.

It is important that you read the manual carefully prior to rst use to learn about the dangers which might arise caused by the operation of the machine (in particular rotating parts, occurring forces or danger of injury).

If you do not have any previous experience with turning, inform yourself before rst start of the lathe. Please

consult turning specialists and knowledgeable people and be instructed. At our company location, we offer courses for beginners and advanced courses.

Electronic frequency converter FU

The Delta frequency converter is programmed particularly quiet and ready for operation. Please do not make any changes to the frequency converter itself. The knurled screw or programming screw on the rear of the FU

drive shall be operated only by qualied personnel. Speed changes to the lathe by the user or

turner may only be made via the potentiometer on the control box with the magnet at the bottom. The FU is programmed with a soft start and soft stop. You can not shorten the phasing-out time after stopping with the handwheel, let the workpiece simply phase out after stopping.

6. Requirements for the set-up location

Requirement Recommendation

Set-up location of the lathe Place the Midi FU - 350 in a dry interior close to a power source (mains).

Watch out for at, rm and stable surface. Allow sufcient space in front of the machine as a workspace.

Other established machines in the workshop shall not affect the operation of the lathe.

Lighting and ventilation Make sure that there is a good light (illuminance levels according to DIN5035)

and ventilation. Additionally use an adjustable lighting system for your workspace on the lathe, so that no shadows will be thrown on the workpiece. We recommend the establishment of a light source which worth at least 300 LUX, better has a 500 LUX on the cutting edge. If possible, place the machine near a window.

Electrical equipment A suitable standard household 230 V socket which is fused with 16 amp. is

required to operate the lathe. Electrical cables and sockets must comply with local electrical regulations. If in doubt, ask your professional electricians. Avoid the use of an extension cord (see also the chapter « Connection of the lathe to the power supply»).

Ventilation Ventilate your workplace sufciently. The degree of ventilation depends on the

size of the workshop and the number of nished workpieces. The use of dust extraction systems and lters reduce your health risk.

Working height The lathe should be located such that the spindle center position is at the

height of the operators elbow. Working space Before the lathe shall be a free space of at least 80 cm. Base unit Since the MIDI FU-350 is a benchtop, the operator has to ensure to use a pro-

per installation space or a suitable base unit. Your dealer offers a base unit.

The provided 3/8 «x 50 mm screws can be rmly connected to a base unit

instead of using the feet.
