ASSEMBLY AND ADJUSTMENT

WARNING: To reduce the risk of injury, turn unit off

and disconnect machine from power source before

installing and removing accessories, before adjusting

or changing set-ups or when making repairs. Be sure

the trigger switch is in the OFF position. An accidental start-

up can cause injury.

The machine is fully assembled except for the table and rip fence.

Installing the Machine

To ensure safe operation, the machine has always to be mounted to the

workbench or to the ground. Use diameter 8mm bolts with 100 mm

length.

1. Mark the position of the four mounting holes provided in the base

of the machine on the workbench (p, fig. 1).

2. Place the machine on the workbench and insert the proposed bolts

through the mounting holes into the workbench.

Mounting the Table (ﬁ g. 1, 4A–4F)

1. Turn the table tilt locking lever (i in fig. 1) counterclockwise

approximately half a turn to release the tilt segments (aa in fig. 4B).

2. Swing back the connecting plate (z) which covers the blade slot in

the table (fig. 4A).

3. Place the table onto the segments (aa) with the blade slot pointing

to the front of the machine (fig. 4B).

4. Carefully guide the table along the saw blade and align the holes in

the table with those in the segments.

5. Insert one hex bolt M8 x 20 (bb) with washer into the two front

holes and fasten them hand-tight (fig. 4C).

6. Tilt the table to a 45° angle.

7. Insert one hex bolt M8 x 20 (bb) with washer into the two rear

holes (fig. 4D).

8. Tighten all four bolts using the box spanner.

9. Press the table insert (d) into place (fig. 4E).

10. Swing the connecting plate (z) back into place (fig. 4A).

11. Completely raise the blade guard (c) by turning the height adjuster

(k) clockwise (fig. 1).

12. Use a set square to check that the table is at a right angle to the

saw blade when in the horizontal position. If adjustment is needed,

loosen the table tilt locking lever and adjust the grub screw (cc) as

required (fig. 4F).

Mounting the Bandsaw Blade

(ﬁ g. 1, 2, 4A, 4E, 5A–5D)

WARNING: The teeth of a new blade are very sharp and

can be dangerous.

1. Unscrew the two cover retention bolts (h) with box spanner to open

the hinged door (fig. 1).

2. Swing back the connecting plate (z) which covers the blade slot in

the table (fig. 4A).

3. Remove the table insert (d).

4. Guide the blade through the blade slot in the table. Make sure that

the teeth point to the front of the machine and downwards in the

working area (fig. 5B).

5. Carefully insert the blade into the blade guard slot (dd) while turning

it for 90° (fig. 5C & 5D)

6. Position the blade between the guide blocks (s) and (u).

7. Move the blade around the band wheels (ee) and (ff) (fig. 5B).

If necessary, lower the upper band wheel by turning the blade

tension adjuster (f, fig. 5B) counterclockwise.

8. Mount the table insert (d) (fig. 4E).

9. Swing the connecting plate (z) back into place (fig. 4A).

10. Adjust the blade tension, the guide blocks and the support

bearings as described below.

WARNING: Be aware the bandsaw blade shall be replaced

in the described way only. Do never fit other bandsaw blade

dimensions as specified under Technical Data.

Adjusting the Blade Tension (ﬁ g. 6A)

The correct tension depends on the width of the blade used. Refer to

the table on the machine.

Adjust the blade tension using the blade tension adjuster (f) until the

scale indicates the tension corresponding to the blade width.

Adjusting the Blade Position (ﬁ g. 1, 6B & 6C)

The blade must be centred on the rim of the band wheels.

1. Open the hinged cover as described above.

2. While rotating the upper band wheel with one hand, slightly rotate

the blade centring adjuster (g) with the other (fig. 1, 6C).

WARNING: Do not touch the blade but rotate the upper

band wheel with your finger on one of the spokes.

Adjusting the Blade Guide Blocks and Rear

Support Bearings (ﬁ g. 2, 7A–7C)

During the sawing operation, the blade is exposed to frontal and lateral

forces. The rear support bearings (q) are positioned 0.5 mm behind the

blade to control the blade front-to-back movement. The 45° and 90°

guide blocks are positioned 0.1 mm from the blade to control the lateral

blade position.

1. Remove the table insert and tilt the table to 45°.

2. Slacken the grub screws (r) and position the rear support bearings

(q) away from the blade (fig. 7A).

3. Adjust the knurled knob (gg) to position the blade guide blocks just

behind the blade teeth (fig. 7A).

4. Position the rear support bearings (q) 0.5 mm behind the blade and

tighten the grub screws (r) (fig. 7A).

5. Slacken the grub screws (t) and (v) and insert the blade guide

blocks (s) and (u) in the holders (fig. 7A).

6. Set the guide blocks to a distance of approx. 0.1 mm from the

blade.

7. Tighten the grub screws (t) and (v) (fig. 7A).
