−
a suitable guide for firm sup-
port 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 immedi-
ately.
•
Assume correct work position
(the band saw blade's teeth must
point towards the operator).
•
Never cut more than one work-
piece at a time – and also no bun-
dles containing several individual
pieces. Risk of personal injury if
individual pieces are caught by
the saw blade uncontrolled.
c
Drawing-in/trapping 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 and wires
are attached or which contain
such materials.
7.1
Adjusting the Upper
Blade Guide
The height of the upper blade guide
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!
Turn the machine OFF and wait for
the band saw blade to stop before
adjusting the upper blade guide or
the saw table.
1.
Loosen screw
.
2.
Set the upper blade guide
with
the twist handle
to the desired
height.
3.
Re-tighten screw
.
Cutting speed adjustment
1.
Open the lower housing door.
2.
Slacken the V-belt by turning the
tension crank handle anticlockwise.
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.
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.
Re-tighten the V-belt by rotating the
crank clockwise (the V-belt must be
able to be depressed in the middle
about 10 mm).
5.
Close the lower housing door.
7.2
Sawing
1.
Check the band saw blade tension
(see 'Tensioning the band saw
blade').
2.
If necessary, adjust the table tilt.
3.
Select rip fence and table tilt for the
type of cutting operation to be car-
ried out.
A
Hazard generated by a jam-
ming workpiece!
When sawing with the rip fence and a
tilted saw table, the rip fence must be
installed on that side of the saw table
which is tilted downward.
4.
Set upper blade guide 3 mm above
the workpiece.
3
Note:
Always make a trial cut in a piece
of scrap to verify settings; correct if nec-
essary before cutting the workpiece.
5.
Place workpiece on the saw table.
6.
Start saw.
7.
Cut workpiece in a single pass.
8.
Switch off if no further cutting is to
be done immediately afterwards.
9.
If no further cutting is to be done
immediately afterwards: decrease
the bandsaw blade tension and
attach a notice indicating that the
bandsaw blade tension must be
reset prior to the next cutting opera-
tion to the machine (see 'Tensioning
the bandsaw blade').
A
Danger!
Prior to all servicing:
1.
switch machine OFF;
2.
Wait for saw blade to stop
3.
Unplug mains cable.
−
Check that all safety devices are
operational again after each service.
−
Replace damaged parts, especially
safety devices, with genuine
replacement parts only, since parts
not tested and approved by the
manufacturer can cause unforesee-
able damage.
−
Repair and maintenance work other
than described in this section should
only be carried out by qualified spe-
cialists.
