2.3 RECOMMENDED PROTECTIVE CLOTHING

• Gloves for moving work material and when carrying out the blade changes;

• Non-slip shoes;

• Protective eye glasses.

2.4 NOISE EMISSION

The measurements of noise, in the working position and during operation, were carried out under the standard ISO 7960 annex "J":

Instantaneous acoustic pressure: (Constant K4 dB measured in accordance with EN150 3746: 1995)

Sound power level (no load) <90 dB(A)

Sound power level (load) <100 dB(A)

Sound Pressure level (no load) <80 dB(A)

Sound Pressure level (load) <90 dB(A)

The figures quoted are emission levels and are not necessarily safe working levels. Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not further precautions are required. Factors that influence the actual level of exposure of the workforce include the characteristics of the work room and the other sources of noise etc. i.e. the number of machines and other adjacent processes. Also the permissible exposure level can vary from country to country. This information, however, will enable the user of the machine to make a better evaluation of the hazard and risk.

2.5 PRESCRIBED USE OF THE MACHINE

The machine was designed for cutting solid wood, wood derivatives, materials similar to cork, hard rubber and hard plastic materials using suitable blades.

THESE MACHINES MUST NOT BE USED TO CUT OTHER MATERIALS THESE MACHINES MUST NOT BE USED TO CUT METALS

2.6 HAZARDS

3. Installation

3.1 LIFTING

The machine can be lifted using a fork-lift truck, placing the forks under the feet or by using a “SLING”, as shown, with a lifting capability of 2000 Kg.

3.2 POSITIONING THE MACHINE

For a correct and rational organisation of the work area:

• Install the machine in an area that will not amplify vibration or noise.

• Ensure that the work area has adequately lighting.

• When placed between other machinery there should be a space of at least 80 cm. It is necessary to anticipate sufficient space for cutting long work pieces traversely and for the fitting of rollers or other types of support in front and at the rear of the table.

There are four holes for fixing the machine to the floor. When fixing to the floor it is recommended not to over tighten the fixtures to avoid increasing vibration. It is also advisable to place anti-vibration materials between the floor and the base of the machine.

NOTE: Due to the height of the machine, the centre of gravity will also be high causing the machine to be unstable or top heavy. The machine, where possible should always be fixed directly to a solid floor using appropriate fixings for the type of floor.

Extra care should be taken when moving the machine to ensure that it cannot fall. Always ensure that machine is fully supported and operators stand well clear whilst the machine is moved.

3.4 ELECTRICAL CONNECTION - START UP

Electrical installation should be carried out by competent, qualified personnel. The mains connection should be made using the terminal box. Ensure that the mains supply corresponds with that of the machine, use cables of a section suitable for the power of the motor. For a supply tension of 400 V the minimum section recommended is 2.5 mm, including the earth wire. For a mains supply of 230 V or a power rating greater than 15 A it will be necessary to increase the section of the connecting cables.

Connect the phase wires to the terminals R- S - T (L1 - L2 - L3) and the earth wire to the earth terminal. On initial start-up check the direction of rotation, if it is incorrect then invert the two phase wires (for machines with 3 phase supply). Direction of rotation of machines with single-phase supply is pre-determined during production . On completion of the installation check that the terminal box is closed correctly and that the plug points are locked. Starting the machine :

WARNING: Do not allow familiarity (gained from frequent use of your machine) to cause complacency. Always remember that a careless fraction of a second is sufficient to inflict severe injury.

NOISE EMISSION

The measurements of noise, in the working position and during operation, were carried out under the standard ISO 7960 annex "J":

Instantaneous acoustic pressure <130.0 dB

The value of the noise level indicated is an emission level and doesn’t necessarily represent safe working levels. Although there is a relationship between emission levels and exposure levels, it isn't precise enough to use in a way to determine whether it is necessary, or not, to implement further precautions. The factors that determine the true exposure level to operators are: the amount of exposure time, the characteristics of the working environment, other sources of dust and noise etc.. The permitted exposure level limits vary from country to country. this information allows the machine user to better evaluate the dangers and risks.

PRESCRIBED USE OF THE MACHINE

The machine was designed for cutting solid wood, wood derivates, materials similar to cork, hard rubber and hard plastic materials using suitable blades. Consult Startrite on Tel:01246 561 520 for advice on the most suitable blade selection. See section 4.2. THESE MACHINES MUST NOT BE USED TO CUT OTHER MATERIALS THESE MACHINES MUST NOT BE USED TO CUT METALS.

ATTENTION Bandsaws still present risks that cannot be eliminated by the manufacturer. Therefore the user must be aware that wood working machines are dangerous if not used with care and all safety precautions adhered to.

ATTENTION!! DISCONNECT THE ELECTRICAL SUPPLY BEFORE EVERY ADJUSTMENT

ATTENTION!! IN CASES OF BLADE BREAKAGE WAIT UNTIL THE UPPER BAND WHEEL HAS COMPLETELY STOPPED BEFORE OPENING THE DOOR.

6.2 CHOICE AND MAINTENANCE OF BLADES

The table below defines the blade length and maximum width, depending on the type of the machine. Selection of width and type of tooth depends upon the materials to be cut and the type of operation, narrow blades are suitable for cutting curved lines, profiles etc and wide blades are best for straight cutting. It is advisable to use finer teeth for hard woods or thin material and coarser teeth for softwoods or deep material. In every case, the distance between each tooth should be sufficient to clear the sawdust produced during the cutting operation. If the clearance is not correct this can cause overheating and jamming of the blade, causing subsequent breakage.

Do not use flawed or deformed blades. It is highly recommended that the blade be changed regularly. Use a specialised saw doctor for welding, sharpening and re-setting blades. The use of high quality blades is also recommended.

Causes of blade breakage:

• Excessive blade thickness in relation to the band wheel size.

• Defective welding

• Incorrect tension, particularly if the blade is over tensioned the tension spring no longer fulfils its function

• Overloading the blade caused by using a badly ground or badly set blade, or by not slackening the tension

• After use it is recommended to slacken the tension, especially overnight, (placing a visible notice of this operation on the machine). Re-tension before next operation.

• Misalignment of the bandwheels due to unauthorized intervention of the regulating screws of the lower band wheel.

• Irregularity of bandwheels surface, e.g an accumulation of sawdust whilst cutting resinous materials.

6.6 BLADE MOUNTING AND ADJUSTMENT

To mount blade first remove the steel bar (A of FIG. 6.6) underneath the table, and the table insert ( (A) FIG. 6.7) Place the blade onto the band wheel checking the teeth are in a correct position, and tighten the tension using the handwheel ( (A) of FIG. 6.8). The correct tension value is indicated on the tension scale inside the upper door, the indicated value corresponds to the width of the blade. (e.g. for blade width 25 mm tighten until no. 25 appears on the indicator).

Turn the bandwheels manually, checking that the blade does not interfere with any fixed parts and that the blade is placed correctly on the bandwheels. The points of the teeth should slightly protrude over the edge of the bandwheels. To adjust the blade position on the bandwheels slacken the locking lever ( (B) of FIG. 6.8), and then turn the knob ( (C) of FIG.6.8): the blade will move inwards when turning the knob clockwise and the blade will move further out when turning the knob anti-clockwise; A quarter of one turn is sufficient to make a noticeable displacement. Tighten the locking lever after the blade is positioned correctly.

Then reinstall the table insert, close the band wheels accessing doors.

IMPORTANT NOTE : After use we recommend slackening the blade tension, and to display a visible sign on the machine advising of this procedure. Remember to check and re-tension before use. This operation prevents damage to the band wheel tyres.

6.7 SETTING THE SAW BLADE GUIDE & GUARD

ADJUSTING THE SAW BLADE GUARD The adjustable saw blade guard should be positioned as close as possible to the workpiece. To adjust the height, release the locking knob ( (D) of Fig.6.8 ) and turn the handwheel ( (E) of Fig. 6.8) to adjust the guard up or down. Lock the knob once the correct position of guard is obtained. This operation must always be carried out while the machine is stopped.

BLADE GUIDE ROLLER BEARINGS The side rollers should almost touch the blade, to prevent vibration during operation and ensure correct direction of cutting. The positioning of these rollers is controlled by screw ( (A) of Fig.6.9), once they have been adjusted, tighten grub screw ( (B) of Fig.6.9); they should be 2mm behind the teeth of the blade. The thrust shaft prevents excessive backward movement of the blade whilst in operation and should be 1-2 mm from the back of the blade: this can be adjusted by screw ( (C) of Fig.6.9).

LOWER SAW BLADE GUIDE To adjust the lower blade guide move the table insert and adjust it from the top of the table. The lower blade guide should be positioned as close as possible to the workpiece (5-10mm)

The side rollers should lightly touch the blade, to prevent vibration during operation and ensure correct direction of cutting. The positioning of these rollers is controlled by screw ( (A) of Fig.6.10), once they have been adjusted, tighten nut ( (B) of Fig.6.10); they should be 2mm behind the teeth of the blade. The thrust shaft prevents excessive backward movement of the blade whilst in operation, and should be 1-2 mm from the back of the blade: this can be adjusted by screw ( (C) of Fig.6.10).

6.8 TABLE INSERT FOR DUST EXTRACTION

The machines are equipped with a removable plastic insert under the worktable(A of FIG.6.11), the insert improves dust extraction. It is recommended that the insert “ A “ be replaced when the blade cutting clearance widens, this will maintain maximum efficiency of dust extraction.

6.9 CUTTING DIRECTION AND PARALLELISM

If the cut is not perfectly parallel when using the parallel rip fence the possible causes are:

• Incorrect grinding and setting of the blade

• Insufficient blade tension

• Incorrect setting of the parallel rip fence in respect of the saw blade; to adjust the parallelism of the guide, slacken, without removing, the 2 screws (B of FIG. 6.11), adjust the guide position and firmly re-tighten the 2 screws.

6.10 TILTING THE WORK TABLE

7. Safety Advice

a) Machine out of order Before making any adjustments or repairs to the machine, disconnect from the electrical supply. If any faults are suspected, disconnect the electrical supply and put a visible notice on the machine. Always report faults on the machine (including guards and saw blades) as soon as they are discovered. b) Before operating

• Keep the surrounding floor space clean;

• Wear suitable clothing, not loose garments;

• Check that the blade is sharp, correctly tensioned, the correct width, and correctly positioned on the bandwheels and always observe the maximum speed marked on the saw blade;

• Use support stands for long or wide material;

• Use a dust extractor of adequate performance as detailed in section 3.3 of this manual. c) During operation Never clean the table with hands, use a brush or a piece of wood. Do not remove off cuts or work pieces from the cutting area unless by using a push stick. In case of an emergency such as blade breakage or other emergency do not attempt to intervene before the bandwheels have completely stopped. When the band wheel has stopped, lower the upper blade guides to the level of the table, loosen the blade and leave a sign advising of this operation. REMOVE THE ELECTRICAL CONNECTION PLUG. d) During maintenance

• Place the machine out of order as indicated above;

• Use gloves to handle the saw band;

• Periodically check the electrical grounding of the machine. e) Tensioning When the machine is not in use, for example at the end of a shift, release the saw blade tension and place a notice on the machine to indicate this and to remind the next user to adjust the tension before starting up. f) Guard removal/replacement Where guards are removed replace them in accordance with the manufacturer's instructions. g) Noise reduction Regular maintenance of saw blades, extraction system, cleaning and lubrication of the saw blade etc. is necessary to help control machine noise. h) Operator training It is essential that all operators are adequately trained in the use, adjustment and operation of the machine. This covers in particular:

other principles of machine setting and operation, including the correct use and adjustment of workpiece holding and guiding devices and guards;

• the safe handling of the workpiece when cutting;

• the use of personal protective equipment for ear and eye protection. i) Tooling Care should be taken to avoid damaging the saw blade. When not in use, untensioned band saw blades should be coiled and secured. They should be stored in a safe, dry place. Before use they should be checked for damaged teeth and cracks.

• To avoid cracking, tensioned saw blades should be stored in accordance with Fig 7.1.

• At least two operators will be needed to change a wide saw blade.

• Suitable carrier equipment should be provided for transporting tensioned wide saw blades.

• Suitable gloves (or other handling aids) should be worn whenever saw blades are handled. j) Saw blade thrust wheel The purpose of the thrust wheel on a table band saw is to give support to the saw blade when cutting. Position it just clear of the back of the saw blade when the saw blade is running free after being strained and tracked. Lack of clearance will cause grooving of the thrust wheel and lead to saw blade failure. k) Machine operation It is necessary to adjust the adjustable saw blade guard as close to the workplace as practicable. l) Straight work Always use a fence for straight cutting, to prevent the workplace rocking or sliding. When hand feeding against the fence, it is necessary to use a push stick for feeding close to the saw blade. m) Cross cutting round stock If cutting round stock it is necessary to secure the workpiece against rotation by using a jig or holder and to use a saw blade suitable for cross cutting. n) Operator training It is essential that all operators are adequately trained in the correct use and adjustment of safety appliances such as jigs, templates and extension tables.

8. Maintenance

BEFORE ANY INTERVENTION ALWAYS DISCONNECT THE ELECTRICITY SUPPLY

Periodically check that all screws are tightly fastened and the condition of the various guards

V belts

After the first few hours of operation it is necessary to check that the tension of the belts is correct. To control the tension of the belts push the mid-point of the belt applying 3-4 Kg of pressure, the displacement should not exceed 5-6 mm. To adjust the belt tension turn the handwheel (A, FIG.

8.1) clockwise, this will increase the tension. It is recommended that the correct belt tension is maintained as loose belts

reduce the motor power and can increase the braking time. Belts that are too tight may become hot.

To change the belts

Slacken the tension as described above, remove the screw (“B”, FIG. 8.1), pull-out the band wheel from the shaft, repeat the operations in reverse to re-assemble. (CAUTION: Bandwheels are heavy and assistance may be required)

Dismantling the upper fly-wheel

To remove the upper flywheel, follow the same procedure as for the bottom flywheel.

Replacement of rubber covering of the fly-wheels

It is recommended that this be carried out by a competent specialist or the manufacturer. This is because the rubber covering is not only glued onto the fly-wheel, but also ground in a crown form. It is strongly advised not to grind and shape the rubber directly on the machine using gouges, files or abrasives.

Cleaning and lubricating

Periodically clean the inside of the machine with the aid of a dust extractor for any saw-dust deposits, remove any resinous deposits from the flywheels surface. The fly-wheel bearings do not require any greasing. It is not necessary to lubricate any part or component of the machine as the sawdust circulating within will adhere to any oiled or greased surface jeopardizing the sliding of moving parts such as the shaft of the blade guide adjustment and the slide of the tensioning group.

Frequently control the cleanliness of the rubber surfaces on the fly-wheels, particularly in cases of cutting resinous materials or chip-board. Clean the surfaces, while machine is not in motion , of any resinous deposits taking care do not damage the surface.

• Incorrect sharpening and consequent overheating, otherwise incorrect setting of the teeth.

• Incorrect blade thickness in relation to bandwheels diameter.

• The band wheel tyres are damaged or have incrustation deposits.

• Badly aligned bandwheels: requires correction by a qualified technician.

The blade is cracked at the back

• Excessive feed during cutting.

• Imperfect weld alignment: eliminate badly welded part and repeat the weld.

• The rear thruster of the blade guide is damaged.

The blade breaks at the weld

• Overheating of the blade during welding: remove the weak area and repeat the welding.

• Cooling down the weld too quickly after welding, proceed as above.

The machine stops with the blade jammed into the workpiece

• Stop the motor and release the brake, widen the cut using a wedge to aid removing the workpiece, after this operation check the blade and its position on the bandwheels before recommencing.
