 Remaining hazards

The machine has been built using modern technology in accordance with recognized safety rules. Some remaining hazards, however, may still exist.

• Only process selected woods without defects such as: Branch knots, edge cracks, and surface cracks. Wood with such defects is prone to splintering and can be hazardous.
• Wood that is not correctly glued can explode when being processed due to centrifugal force.
• Trim the workpiece to a rectangular shape, and center, and correctly secure it before processing. Unbalanced workpieces can be hazardous.
• Injuries can occur when feeding workpieces if tool supports are not correctly adjusted or if turning tools are blunt. Sharp turning tools which are free of defects are necessary for professional turning.
• Long hair and lose clothing can be hazardous when the workpiece is rotating. Wear personal protective gear such as a hair net and tight-fitting work clothes.
• Sawdust and wood chips can be hazardous. Wear personal protective gear such as safety goggles and a dust mask.
• The use of incorrect or damaged main cables can lead to injuries caused by electricity.
• Even when all safety measures are taken, some remaining hazards which are not yet evident may still be present.
• Remaining hazards can be minimized by following the instructions in „Safety Precautions“, „Proper Use“ and in the entire operating manual.

Start-up

Observe the safety notes in the operating instructions before operating the machine.
Remove the tensioning spindle or the chuck from the spindle in addition to any step-up tools before first operating the machine!
Speed adjustment
The speed can only be adjusted once the machine has been unplugged.
The correct number of revolutions is visible on the speed diagram located on the headstock. The speed diagram is intended for medium-hard dry woods.
The appropriate speed is based on various factors such as:

• type and composition of woods
• seasoned, dry woods
• diameter and length of workpieces
• squared or unbalanced woods
• width of pre-worked, balanced workpieces
• woodturner tools and technique
• workpieces out of glued wood

Successful wood turning does not result from high speeds, but rather, from the correct use of the machine.
Guidelines for speed adjustment
Low speeds for:

• workpieces with large diameters
• hard workpieces with large diameters
• long, unbalanced workpieces
• glued pieces of wood

Speed adjustment (Fig. 2+3)

• Open the casing by rotating the lock screw of a revolution to the left.

• Loosen the socket-head screw (C).

• Using the lever, raise the electric motor and move the belt to the desired level. The belt must lie exactly in the grooves of the belt disc.

• Lower the electric motor into place and tighten the belt by applying light pressure to the lever (2). Tighten the socket-head screw (C).
  NOTE: Extremely high belt tension causes rapid wear of the belt.

• Close the casing and lock it into place by turning the screw of a revolution to the right.

• When the cover is closed, read the adjusted speed from the viewing window.

• When working with highly unbalanced workpieces, select a speed at least one level lower.

Driver, Fig. 1.1, 5
The driver is used exclusively for work between both centers.
Faceplate, figure 1.1, 2
The face plate is used with flat larger tools.
Change of the clamping tools

• Loosen the grub screw on the shaft of the clamping tool.
• Retain the spindle with mandrel, and release the clamping tool with the hexagonal spanner.

Tailstock, Fig. 1.1, 6

• Once the eccentric clamp has been loosened, the tailstock can be moved over the entire length of the bed and can be secured at any distance from the headstock.
• To insert a workpiece between the centers, loosen the binder, and turn the sleeve approx. 20 mm outward and clamp.
• Slide the tailstock to the workpiece and place the tailstock center into the sunken point in the center of the workpiece.
• Screw out the tailstock sleeve until the tailstock center rests securely in the wood. Retighten the binder.
• Turn the workpiece to see if it rests securely between the two centers and can be rotated freely.

Tailstock center replacement, Fig. 1.1, 4

• Turn the tailstock spindle sleeve totally backward until the tip can be removed.

Tool holder, Fig. 1.1, 3

• The tool holder both ensures the safe use of wood-turning tools and at the same time serves as a support for the hand.
  The height of the tool holder can be adjusted once the binder has been loosened. To turn further, pull in the direction indicated by the arrow.

• Place the tool holder at a distance of 1 – 3 mm from the workpiece. Check the adjustment in addition to rotating the workpiece by hand.

• Set the tool holder ca. 3 mm above the axis of the workpiece. Check the adjustment once again by rotating the workpiece by hand.

• Once the eccentric clamp has been loosened, the holder console can be moved along the entire length of the bed and in the direction perpendicular to the workpiece. Furthermore, the holder console can be tilted over approx. 45º to either side.

• To work with a plane surface, turn the tool holder 90º and place up against the surface to be worked. Depending on the wood-turning tool, place the tool holder up to 6 mm underneath the axis of the workpiece.

Operations

A perfect and sharp wood turner tool is a precondition for professional wood- turning.
Selection of materials
• Wood to be turned must be of good quality and without imperfections such as fissures against the grain, a marred surface, or knots. Faulty wood tends to split and becomes a risk for both the operator and the machine.
• Workpieces that have been glued together should only be processed by experienced craftsmen. Because the workpiece can explode as a result of developing centrifugal force, turning such wood demands careful gluing without weak points.
Note: Beginners should first master fundamental skills by working exclusively with solid material.
Preparation of the materials
• To turn long pieces of wood, the material must be cut into a square form beforehand.
• To turn a cross-arm, the material must be cut to size in its natural state as well. Saw out the rough form with a band saw. An octagonal form is recommended for the material so that vibrations are reduced.

Centering of the workpiece, Fig. 05
Centering the prepared workpiece is an important operation to be performed before placing it into the machine.
Centering consists of measuring the middle point of the workpiece and marking it with a center punch.
Make a depression of 1.5 to 2 mm in the middle point. If the workpiece has not been centered exactly, strong vibrations will develop as a result of the imbalance. It is possible that the workpiece could be hurled outward as a result.
NOTE:
The exact centering of the workpiece produces smooth concentricity. While working with the turner

• Work with a rough workpiece should be conducted at low speeds.
• Only after the wood has been pre-turned (the pre-turning operation is complete once the basic form of the workpiece as well as an even concentricity have been achieved) can the speed be raised.

TURN OFF AND UNPLUG THE MOTOR FIRST

• The live center must be readjusted from time to time with the hand wheel. This operation only should be performed when the motor has been turned off. The tailstock center should rest firmly in the wood.
• Turn the workpiece by hand to check if it rests securely.

Marking of the workpiece
Sometimes the workpiece has to be taken out before it has been completed. It is advantageous to mark the workpiece and the driver with a pencil first. When placing the workpiece back in the machine, match the marks on the workpiece and the driver.
Specialized literature
Specialized shops offer appropriate specialized literature
about woodturning. They can be a great help for beginners in their work as well as a source of ideas for experts.

Electrical connection

The installed electric motor is completely wired and ready for operation.
The customer’s connection to the power supply system, and any extension cables that may be used, must conform with local regulations.
Important remark:
The motor is automatically switched off in the event of an overload. The motor can be switched on again after a cooling down period that can vary.
Defective electrical connection cables
Electrical connection cables often suffer insulation damage.
Possible causes are:

• Pinch points when connection cables are run through window or door gaps.
• Kinks resulting from incorrect attachment or laying of the connection cable.
• Cuts resulting from running over the connecting cable.
• Insulation damage resulting from forcefully pulling out of the wall socket.
• Cracks through the aging of insulation.

Such defective electrical connection cables must not be used as the insulation damage makes them extremely hazardous.
Check electrical connection cables regularly for damage. Make sure the cable is disconnected from the mains when checking.
Electrical connection cables must comply with the regulations applicable in your country.
Single-phase motor, Fig. 06

• The mains voltage must coincide with the voltage specified on the motor’s rating plate.
• Extension cables up to a length of 25 m must have a cross-section of 1.5 mm 2, and beyond 25 m at least 2.5 mm 2.
• The connection to the mains must be protected with a 16 A slow-acting fuse.

Only a qualified electrician is permitted to connect the machine and complete repairs on its electrical equipment. In the event of inquiries please specify the following data:

• Motor manufacturer
• Type of current of the motor
• Data recorded on the machine’s rating plate
• Data recorded on the switch’s rating plate

If a motor has to be returned, it must always be dispatched with the complete driving unit and switch.

Maintenance

• Overhauls, maintenance work, cleaning, as well as the elimination of any malfunctions must only be undertaken after turning off the motor.
• All protective and safety equipment must be reinstalled immediately upon completion of any repair or maintenance work.
• Clean and lightly oil the spindle thread of the tool holder when changing tools.
• When possible, the tail stock sleeve should be removed by unscrewing it, cleaned, and then sprayed with a dry lubricant. Grease the threaded spindle.
• Check the eccentric clamp of the tailstock as well as the tool holder and adjust if necessary. In addition, tighten the hex nut under the bracket.
• Check the drive belt and replace it when necessary.
