ENGLISH

Never cut several work pieces at
the same time – and also no bun-
dles containing several individual
pieces. Risk of personal injury if
individual pieces are caught by
the saw blade uncontrolled.

Entangelement hazard!

Do not wear loose clothing, jewel-
lery, or gloves, which may get
caught and wound up by revolv-
ing machine parts.

Contain long hair with a hairnet.

Never cut stock to which ropes,
cords, strings, cables or wires are
attached or which contain such
materials.

Upper blade guide adjustment

The height of the upper blade guide

(68)

needs to be adjusted:

prior to every cutting operation, to
accommodate the height of the work
piece (the upper blade guide should
be set approx. 3 mm above the work
piece);

after adjustments of band saw blade
or saw table (e.g. band saw blade
change, tensioning of the band saw
blade, saw table alignment).

Danger!

Before adjusting the upper

blade guide and saw table tilt:

switch machine OFF;

wait until the band saw blade has
come to a complete stop.

Set upper blade guide

(68)

with the

adjusting knob

(69)

to the desired

height.

Cutting speed adjustment

Open the lower housing door.

Slacken V-belt by turning the crank
clockwise.

Put V-belt on the required pulley of
the driving wheel (lower band saw
wheel) and the corresponding motor
pulley – note label inside the lower
housing door.

Caution!

The V-belt must run either on

both front or both rear pulleys. Never
have the V-belt run diagonally!

V-belt on front pulley
= low speed, high torque.

V-belt on rear pulleys
= high speed, low torque.

Tighten the V-belt again by turning
the crank counter-clockwise (half-
way between the pulleys the V-belt
should flex approx. 10 mm).

Close the lower housing door.

7.1

Sawing

Choose and install a table insert
extrusion suitable for the type of cut
to be performed:

table insert extrusion with a nar-
row slot for standard cross cuts
only;

table insert extrusion with bevel-
led slot for bevel cuts also.

Adjust the band saw blade speed.

If necessary, adjust the table tilt.

Risk of kickback (work piece is

caught by the band saw blade and
thrown against the operator)!

Do not jam any work pieces.

Select rip fence and table tilt for the
type of cutting operation to be car-
ried out.

Set upper blade guide 3 mm above
the work piece.

Note:

Always make a trial cut in a piece

of scrap to verify settings; correct if nec-
essary before cutting the work piece.

Place work piece on the saw table.

Plug in.

Start saw.

Cut work piece in a single pass.

10. Switch off if no further cutting is to

be done immediately afterwards.

Danger!
Prior to all servicing:

Switch machine OFF;

Wait until the saw has come to a
complete stop.

Unplug power cable;

Check to see that all safety devices
are operational again after each
service.

Replace defective parts, especially
of safety devices, only with genuine
replacement parts. Parts not tested
and approved by the manufacturer
can cause unforeseen damage.

Repair and maintenance work other
than described in this section should
only be carried out by qualified spe-
cialists.
