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.
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
25/40/75/185 mm
Use only sharpened, flawless 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 flaws (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 final tightening
while the band is running evenly.
• Broad sawbands must be tensioned
more firmly than narrow ones.
Setting before initial operation
• 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
6/10/15/ 25mm 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 firmly!
