1. Clamp the workpieces to be sawed in a vice or in another clamping device, i.e. directly between the two clamping jaws and without placing other objects
in between.
2. Bring the workpiece stop (10) in contact with the workpiece, and whilst doing so hold the saw band away from the workpiece.
3. Then switch the metal band saw on. To do this, press the on/off switch (5) and the release switch (6) at the same time.
4. Once the metal band saw has reached the desired speed, tilt the main body of the machine slowly and cautiously such that the saw band (11) comes into
contact with the workpiece. Do not apply any additional pressure. Be careful to avoid the saw band (11) coming suddenly and abruptly into contact with the
surface of the workpiece. This results in serious damage to the saw band. In order to achieve the maximum service life of the saw band, ensure that no sudden
impacts arise at the start of the sawing process.
5. Straight cuts can be achieved if the saw band is flush with the side surface of the engine housing. Be aware of your viewing angle in this case. Twisting the
saw band or holding it at an angle causes the cut to run alongside the cutting line, and this reduces the service life of the saw band.
NOTE: If the band saw becomes jammed or stuck in the workpiece during sawing, release the on/off switch (5) immediately to avoid damage to the saw
band and engine.
6. The net weight of the metal band saw delivers the most efficient cutting pressure. If the pressure is increased by the operator, the saw band (11) becomes
slower and the service life of the band is reduced.
7. End pieces that are so heavy they would cause injuries if they were to fall should be supported. Wearing safety shoes is strongly recommended.
Attention: End pieces may be hot and sharp.
8. Hold the metal band saw tight in both hands when sawing.
9. Prevent the metal band saw from falling against the clamped or supported workpiece after cutting.
Clamping the workpiece (Fig. 16-18)
1. First, open the workpiece clamping lever (25) anti-clockwise.
2. Pull the moving clamping jaw (24) back.
3. Place the workpiece on the front fixed clamping jaw (23).
4. Slide the moving clamping jaw (24) toward the workpiece.
5. Clamp the workpiece using workpiece clamping lever (25) anti-clockwise.
Mitre cut 0°- 45° (Fig. 19)
Mitre cuts of 0°-45° to the working surface can be carried out using the metal band saw.
1. To do this, open the locking handle (graduated scale) (26).
2. Set the support arm base plate (22) to the desired angle.
3. Re-tighten the locking handle (graduated scale) (26).
Sawing process with the saw table (Fig. 20 - 21)
Attention: Keep the mains cable away from the sawing area during the sawing process.
Risk of injury! Keep your hands away from the sawing area.
Mitre cuts of 0°- 45° to the working surface to the left can be carried out using the metal band saw.
1. Set the desired angle as described under point "Mitre cut 0°- 45°".
2. Clamp your workpiece as described under point "Clamping the workpiece".
3. Switch the metal band saw on. To do this, press the on/off switch (5) and the release switch (6) at the same time.
4. Once the metal band saw has reached the desired speed, pull the safety bolt (27) (see fig. 3) and tilt the main body of the metal band saw slowly and
cautiously downwards so that the saw band comes into contact with the workpiece. Do not apply any additional pressure.
Be careful to avoid the saw band coming suddenly and abruptly into contact with the surface of the workpiece. This results in serious damage to the saw band.
In order to achieve the maximum service life of the saw band, ensure that no sudden impacts arise at the start of the sawing process.
NOTE: If the saw band becomes jammed or stuck in the workpiece material during sawing, release the on/off switch (5) immediately to avoid damage to
the saw band and engine.
5. The net weight of the metal band saw delivers the most efficient cutting pressure. If the pressure is increased by the operator, the saw band becomes slower
and the service life of the band is reduced.
6. Swivel the metal band saw back into the initial position after the sawing process. Make sure that the metal band saw does not tilt back down again.
Attention: Wait until the saw band has come to a complete standstill before removing the workpiece.
OPERATING INSTRUCTIONS
The following recommendations are examples for safe use of metal band saws.
The following safe working methods are considered to contribute to safety but may not be appropriate, fully or extensively applicable for every use.
They cannot cover all possible hazardous conditions and must be interpreted carefully.
