7. Operation
Danger!
To reduce the risk of personal
injury as much as possible, the
following safety recommendations
should be observed when operating
the saw.
Use personal protection gear:
-
dust respirator;
-
hearing protection;
-
safety goggles.
Cut only one work piece at a time.
Always hold the work piece down on
the table.
Do not jam the work piece.
Do not attempt to stop the band saw
blade by pushing the work piece
against its side.
If the type of work requires, use the
following:
-
work support
－
for long stock,
which would otherwise fall off the
table on completion of the cut;
-
push stick – if distance rip fence –
band saw blade
δ
120 mm;
-
dust collector;
-
an appropriate jig when cutting
round stock, to keep it from
turning;
-
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
working order:
-
band saw blade;
-
upper and lower blade guard.
-
Replace damaged parts at once!
-
Assume correct work position (the
band saw blade's teeth must point
towards the operator).
-
Never cut several work pieces at
the same time and also no bundles
containing several individual
pieces. Risk of personal injury if
individual pieces are caught by
the saw blade uncontrolled
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 materials.
Upper blade guide adjustment
The height of the upper blade guide
(39)
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
(50)
with the
adjusting knob
(49)
to the desired
Cutting speed adjustment
1. Open the lower housing door.
2. Slacken V-belt by turning the crank
clockwise
3. 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.
4. Tighten the V-belt again by turning
the crank counter-clockwise
(halfway between the pulleys the
V-belt should flex approx. 10 mm).
