Adjusting the reading glass

Fig.“5“

The guide tube must project over the sawblade

to such an extent that the scale on the guide

tube is positioned directly under the zero mark

of the magnifying glass.

Release the two belts of the magnifying glass

and set the graduation mark precisely above the

zero mark of the scale.

Retighten the bolts of the magnifying glass.

Setting before initial operation

The electrical current supply is interrupted

by a limit switch when the housing lid is

opened!

Cutting speeds

Fig. „6“

Band saw are quipped with 2 cutting speed.

IMPORTANT!

The cutting speed may only be set while the

machine is at a full stop. Pull the mains plug!

Two levels

460 m/min. for wood and hardwood

775 m/min. for soft wood

V-belt 10 x 1072 mm

Cutting speed - levels I - II

463 m/min. 1 to 3

775 m/min. 2 to 4

The machine is delivered with apre-set

cutting speed of 775 m/min for wood and hard-

wood

Sawband

Selecting the correct sawband is decisive for

cutting performance. Observethe table of the

Operating Instructions.

Narrow sawbands can cut smaller radii than

broad saw bands.

The smallest radius for blade widths

6/10/15/ 25mm

25/40/75/185 mm

Use only sharpened, awless sawbands.

Faulty sawbands increase the risk of acci-

dents and reduce cutting performance.

Changing sawbands

Fig.“8“

The machine is delivered with a new, stan-

dard sawband (15 mm).

The sawband may only be changed when the

mains plug is pulled!

Always wear suitable gloves when handling

sawbands!

The sawband is loosened for removal by

turning the upper handle counterclockwise.

The new sawband is tensioned by turning the

upper handle clockwise.

IMPORTANT when installing a sawband:

• Reset the counterpressure bearings

and guide rollers.

• Check sawband for aws (cracks,

broken teeth) before installation.

• Check the running direction of the

sawband before placing onto the band

wheels.Teeth should point downwards

towards the saw bench.

• The sawband must be placed between

the upper and lower guide rollers.

• Tighten the placed sawband lightly.

• Tum the band wheel clockwise by

hand and carry out the nal tightening

while the band is running evenly.

• Broad sawbands must be tensioned

more rmly than narrow ones.

• Overtensioning of the sawband can

lead to premature breakage.

Sawband path side correction

Fig.“9“

Side correction may only be carried

out with the machine at a tull stop and

with the mains plug pulled!

The sawband must run on the center of the

band wheels. Loosen the knurled nuts (1) on the

underside of the of the handle.

Turn the upper band wheel by hand in the

cutting direction while simultaneously tuming the

handle to the right (+).

The saw band then runs more toward the rear.

When the sawband runs evenly, re-tighten the

knurled nuts on the handle.

Counterpressure bearing

Fig. „10“

lnsure that the sawband runs evenly before

setting the counterpressure bearing.

The setting must be carried out while the

machine is at a full stop!

The counterpressure bearings take the feed

pressure of the workpiece.

Set the counterpressure bearings above and

below saw bench so that they contact the saw-

band lightly. Tum the band wheel by hand in the

sawing direction at the same time.

The counterpressure bearings must run with the

sawband during operation.

Reset the counterpressure bearings every time

the sawband is changed!

Guide rollers

Fig.“11“

lnsure that the sawband runs evenly before

setting the guide rollers.

The setting must be carried out while the

machine is at a full stop!

The guide rollers take the side pressure of the

workpiece.

Reset the guide rollers above and below saw

bench to the suitable sawband width. They may

reach up to the base of the teeth of the saw-

band.

Set the guide rollers so that they contact the

sawband lightly. Tum the band wheel by hand in

the sawing direction at the same time.

The guide rollers must run with the sawband

during operation.

The sawband must not jam!

Reset guide rollers every time the sawband

is changed!

Cutting height adjustment

Fig.“12“

The setting must be carried out while the

machine is at a full stop!

The cutting height is adjustable from 0 - 400 mm

over the beneh.

Height adjustment is carried out continually

using the large hand wheel and remains in any

position due to the automatie clamping function.

For your own safety, always set the sawband

guide as close to the workpiece as possible.

Sawbench

Fig.“13“

The saw bench is set at the factory.

The continuous saw bench swing range reaches

trom + 47° to - 15°.

The greatest swing range allows 45° mitered

cuts.

The setting must be carried out while the

machine is at a tull stop!

One can readjust the bench at a 90° angle to the

sawband using the setting screw (1) under the

bench. (Use a square as an aid)!

Table adjustment to + 47°

• Loosen both lock levers (2).

• Tum the handle (3) clockwise.

• Re-tighten the lock handles (2) in the

desired position according to the scale.

Table adjustment to - 15°

• Loosen both lock levers (2).

• Tum the handle (3) one quarter revolution

to the right and swing the adjustment

screw (1) on the ball handle to the lett.

• Tum the handle (3) counterclockwise.

• Re-tighten the lock handles (2) in the

desired position according to the scale.

Test the exact angle setting of the table with

a sampie piece before beginning work.

Parallel alignment of the sawband

to the saw bench

Fig. „14“

Exact parallel alignment is especially important

for work with the traverse cutting gauge spe-

cial accessory.

Check parallel alignment with the fence rail and

a low angle.

Place the fence rail on the saw band running

upwards and downwards. Place the low angle

on the fence rail as weil as along the longitudinal

groove.

If there are deviations, loosen the 8 hexagonal

nuts of the table attachment swinging segment

and readjust the saw bench appropriately.

Re-tighten the hexagonal nuts rmly!
