ENGLISH
Position power supply cable so it
does not interfere with the work and
is not damaged.
Protect power supply cable from heat,
aggressive liquids and sharp edges.
Use only rubber jacketed cable of suf-
ficient lead cross section.
Do not pull on power supply cable to
unplug.
A
Changing the direction of rota
tion (3-phase motor only):
Depending on phase sequence the
band saw blade may turn in the wrong
direction. This can cause the work-
piece being tossed away when
attempting to cut. Therefore, always
check direction of rotation after every
connection to the power supply.
If the direction of rotation is incorrect,
the electrical connection must be
changed by a qualified electrician!
1. When the saw is assembled and all
safety devices are installed, connect
it to the power supply.
2. Start saw briefly and turn OFF
immediately again.
3. Check the band saw blade's direc-
tion of rotation: in the cutting area
it must run from the top down-
wards.
4. If the band saw blade turns in the
wrong correction, unplug the power
supply cable at the saw.
5. Have the electrical connection
changed by a qualified electrician!
A
Danger!
To reduce the risk of personal
injury as much as possible, the fol-
lowing safety recommendations
should be observed when operating
the saw.
Use personal protection gear:
− dust respirator;
− hearing protection;
− safety goggles.
Cut only one workpiece at a time.
Always hold the workpiece down on
the table.
Do not jam the workpiece.
Do not attempt to stop the band saw
blade by pushing the workpiece
against its side.
If the type of work requires, use the
following:
− push stick – if distance rip fence
– band saw blade ≤ 120 mm;
− work support – for long stock,
which would otherwise fall off the
table on completion of the cut;
− dust collector;
− an appropriate jig when cutting
round stock, to keep it from turn-
ing;
− a suitable guide for firm support
when cutting thin stock layed on
edge.
Before starting work, check to see
that the following are in proper work-
ing order:
− band saw blade;
− upper and lower blade guard.
Replace damaged parts immediately.
Assume correct work position (the
band saw blade's teeth must point
towards the operator).
Never cut several workpieces at the
same time – and also no bundles con-
taining several individual pieces. Risk
of personal injury if individual pieces
are caught by the saw blade uncon-
trolled.
c
Drawing-in/trapping hazard!
Do not wear loose clothing,
jewellery, or gloves, which may get
caught and wound up by revolving
machine parts.
Contain long hair with a hairnet.
Never cut stock to which ropes,
cords, strings, cables and wires are
attached or which contain such mate-
rials.
Upper blade guide adjustment
The height of the upper blade guide (48)
needs to be adjusted:
− prior to every cutting operation, to
accommodate the height of the
workpiece (the upper blade guide
should be set approx. 3 mm above
the workpiece);
− after adjustments of band saw blade
or saw table (e.g. band saw blade
change, tensioning of the band saw
blade, saw table alignment).
A
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.
1. Loosen locking screw (49).
2. Slide the upper blade guide (48) into
desired position.
3. Tighten the locking screw (49)
again.
Cutting speed adjustment
1. Open the lower housing door.
2. Slacken V-belt by turning the crank
clockwise.
3. Shift the V-belt to the desired pulley
on the drive wheel (lower band saw
wheel) and to the corresponding
motor pulley.
A
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.
4. Tighten the V-belt again by turning
the crank counter-clockwise (half-
way between the pulleys the V-belt
should flex approx. 10 mm).
5. Close the lower housing door.
Information on how to set the cutting
speed can also be found on the label on
the inside of the lower housing door.
