7.3
Tensioning the blade
•
CAUTION! Remove the tension from
the blade if the bandsaw is not going to
be used for some time. Be sure to re-
tension the blade before you start the
machine.
•
Turn the tightening screw (9) for
tensioning the blade (25) in a clockwise
direction.
•
The
correct blade tension
checked by applying pressure to the
side of the blade with your finger,
somewhere in the middle between the
two blade pulleys (7+8). You should
only be able to bend the blade (25)
very slightly (approx. 1-2mm).
•
CAUTION! The blade may break if the
tension is too high. BEWARE IF INJURY!
If the tension is too low, the powered
blade pulley (7) will spin while the
blade does not move.
7.4
Adjusting the blade
•
Undo the fasteners (13) and open the
side cover (12).
•
Turn the upper blade pulley (8) slowly
in a clockwise direction. The blade (25)
should run centrally on the blade pulley
(8). If it does not, the angle at which
the upper blade pulley (8) tilts must be
adjusted.
•
If the blade (25) runs more towards the
rear of the blade pulley (8), i.e. towards
the machine housing (24), the setting
screw (22) must be turned in an
anticlockwise direction. Then turn the
blade pulley (8) slowly with the other
hand to check the position of the blade.
•
If the blade (25) runs towards the front
edge of the belt pulley (8), the setting
screw (22) must be turned in a
clockwise direction.
•
After adjusting the upper blade pulley
(8), check the position of the blade (25)
on the lower blade pulley (7). Again,
the blade (25) should run in the middle
of the blade pulley (7). When adjusting
the upper blade pulley you have to turn
it several times until the adjustment
has an effect on the position of the
blade on the lower blade pulley.
•
7.5
Whenever you change the blade you must
reset both the support bearings (30+31) and
the guide pins (28+29).

When adjustment has been completed,
close the side cover (12) again and
secure it with the fasteners (13).
Adjusting the blade guide (Fig. 11-
13)
Undo the screw (33).
Move the support bearing (30) s that it
is almost touching the blade (25).
There should be a gap of approx.
0,5mm.
Re-tighten the screw.
(31)
Disassemble the saw blade (15).
Adjust in the same way that the upper
support bearing was adjusted.
The blade (25) is only supported by the
support
bearings
cutting. During idle run the blade
should not touch the ball bearings.
(Figure 11)
Undo the screw (35).
Move the mount (36) of the guide
bearings (28) so that there is a gap of
approx. 1mm between the front edge
of the guide bearings (28) and the
gullet of the blade in front.
Re-tighten the screw (35)
CAUTION! The blade will be rendered
useless if the teeth touch the guide
bearings while the blade is running.
Undo the screws (37)
Move the two guide bearings (28)
towards the blade so that there is a gap
of approx. 0,5mm between the guide
bearings (28) and the blade (25).
Re-tighten the screws (37).
