Setting the machine up

Danger!

1. Unpack the micro band saw and check for completeness.

Do not connect the machine to the 230V mains supply yet.

Note:

For safety reasons the machine should be fastened with the 5 wood screws to a strong work bench (fig. 2).

Checking tension and fit of the saw band

Note:

The machine is fitted with a saw band 1065 × 0.4 × 5,0 ~mm (14 Z) from the factory.

1. Unscrew four socket head cap screws from the housing 2 (fig. 1) and take the cover off.
2. Check the fit of the saw band in the lower band guide 1 (fig. 3). The guide slot must be exactly vertical. Adjust the band guide after loosening the clamping screw (2).
3. When cutting aluminium, metal, glass, tiles etc. remove plate 1 (fig. 4) to avoid accumulation of chips inside the machine.
4. Install the housing cover.

Note:

When cutting wood or plastic materials the machine should be connected to a dust extractor (vacuum cleaner) to avoid accumulation of saw chips inside the machine.

Using a vacuum cleaner

1. Remove the housing cover 1 (fig. 1), slide the plate 1 (fig. 4) in and connect the vacuum cleaner to the socket 1 (fig. 5).
2. Install the housing cover.

Mounting the work table

1. Unscrew the brass screw from the sawing gap 1 (fig.6) in the working table.
2. Slide the working table 3 (fig. 7) into the respective recess and fasten it with the star-shaped handle screw (2) with washer (1). Set the mark to "0".
3. Screw the brass screw 1 (fig.6) back in.

Tensioning the saw band

Note:

The saw band is tensioned correctly when it runs quietly and without vibrations.

1. Loosen the clamping screw 2 (fig. 8) in direction A for half a turn.

2. Turn the set-screw (1) in direction (A) to tension or in direction (B) to loosen the saw band.

Caution!

An extremely tensioned saw band may break and damage the machine!

1. Tighten the clamping screw (2).

Note:

The saw band must not run sideways off the wheels.

Checking the saw band guide

1. Adjust the upper saw band guide 1 (fig.9) to the width of the respective saw band. The edge A must thereby be in line with line "5" on the scale (e.g. saw band 1065 × 5 × 0.4 ). The band must now touch the rear roller.

Attention!

Switch the machine off and disconnect it from the mains supply when working on the saw band guide.

Adjusting the saw band width

1. Slightly loosen the socket head cap screw 3 (fig.9).
2. Slide the adjusting piece (2) until it matches line "5" on the scale.
3. Tighten the socket head cap screw (3), but not too tight!
4. The saw blade thickness can be corrected by means of the set-screw 4 (fig. 9).

Starting operation

Attention!

The band saw must be connected to a dust extracting device.

The saw must not be operated with the housing door (saw band protection device) open.

The saw band guide must be adjusted as close as possible to the work piece.

1. Set the On-Off switch 4 (fig. 11) to position "0".
2. Connect the machine to the mains supply.
3. Loosen the clamping screw (1) and lower the saw band guide (2) to just above the work piece. Tighten the clamping screw.
4. Switch the machine on (4).

Attention!

Before starting work, adjust the appropriate speed for the saw band and the material.
5. Adjust the band speed with the regulator 3 (fig.11). Refer to the diagram (5) for optimal band speed. The values are, however, only reference values.

Note:

Generally applicable: High band speed for thin material and low band speed for thick material.

Sawing

1. Mark the cut on the work piece. Never brake the band speed by pushing too hard. The saw band must "cut freely". In case of vibrations adapt the band speed respectively.

Free-hand sawing

Press the work piece onto the work table, guide it carefully and only with little force (fig.12a/b). More pressure against the work table, less pressure against the saw band.

Sawing with litre guide

Attention!

Adjustments must only be carried out with the machine switched off.

1. Adjust the desired angle on the litre guide. Press the work piece lightly against the saw band (fig. 13).

Mitre cuts

For litre cuts the working table can be tilted to any angle between 0^ and 45^ .

1. Loosen the clamping screw 1 (fig. 14) and tilt the table to the desired angle. Read the degrees on the scale (2).
2. Tighten the clamping screw (1).

Caution!

Use only saw bands in good condition!

Replace blunt and deformed saw bands immediately!

Always disconnect the machine from the mains supply for cleaning and service work!

Do not run the machine unattended!

Operation with diamond saw band

Note:

A diamond saw band must only be used in combination with a correctly mounted liquid coolant system. This is available as an accessory.

Note:

For operation with a liquid coolant system we recommend the installation of a liquid collecting trough 3 (fig. 15). This trough is available as an accessory. To seal the screwing holes stand the band saw on a rubber plate and fasten it with the wood screws.

Attention!

To install the liquid cooling system follow the enclosed instructions exactly!

Working with a diamond saw band

Caution!

Cutting of radii smaller than 15mm is not possible (fig. 16).

Do not use diamond saw bands for metal, plastic materials or wood.

Notes on the coolant:

Use only commercially available, mineral or synthetic, water soluble coolants.

Concentration: 2 - 5%, depending on material.

Dispose of liquids after work according to instructions from the manufacturer.

1. Switch the machine on.
2. Open the shut-off valve 1 (fig. 17) and adjust the flow. Use enough coolant.

Note:

Only sufficient cooling of the diamond saw band ensures better and quicker cutting of glass and ceramics and prolongs the lifetime of the diamond band.

1. Guide the work piece carefully and only with little force.
2. Close the shut-off valve (1) after finishing work or during breaks.

Changing the saw band

Caution!

Switch the machine off and pull the plug out!

1. Unscrew four socket head cap screws 2 (fig. 18) and take the housing cover (1) off.
2. Unscrew the brass screw 1 (fig. 19).
3. Loosen the clamping screw 3 (fig. 18) for half a turn.
4. Turn the set-screw 4 (fig. 18) until the saw band can be removed from the wheels 2 and 3 (fig. 19).
5. Insert the new saw band into the sawing gap with the non-toothed side forward and the teeth pointing downwards (towards the sawing table).

Note:

There is a possibility that the saw band has "turned over".

In such a case make sure to turn the saw band back. The teeth must point to the front and downwards.

Note:

When changing to a wider or narrower saw band the saw band guide must be adjusted accordingly (see "check the adjustment of the saw band guide").

1. Turn the set-screw 4 (fig. 19) until the saw band is lightly tensioned.

2. Tighten the clamping screw 3 (fig. 18) and reinstall the brass screw 1 (fig. 19).

Caution!

Extreme tensioning can cause damage to the machine and breaking of the saw band.

1. Install the housing cover 1 (fig. 18) and fasten the socket head cap screws (2).

Note:

The saw band must not run sideways off the wheels.

Changing the plastic rings on the wheels

Each wheel is covered with a plastic ring to protect the saw band.

These plastic rings are wear items and must be replaced whenever necessary.

The plastic rings must therefore be examined regularly. In case of a 'hollow shape' caused by abrasion (fig. 20), the respective ring must be replaced immediately.

1. Cut the worn plastic ring (fig. 21) by using a sharp, heated knife.

2. Warm up the new plastic ring for 10 minutes in hot water (not boiling).

3. Press the plastic ring firmly onto the wheel, until it sits perfectly in the groove.

4. Install the wheel and the housing cover and fasten it with the 4 socket head cap screws.
