7.1. Mounting the saw table (Fig. 3 - 5)
Remove the web panel (4).
Place the saw table (15) on the machine housing
(25) from the right and fasten with 3 fixing screws
(27). Make sure that the blade (26) is positioned
exactly in the center of the saw table.
Re-insert the web panel (4).
Insert the plastic table insert (17) into the table
from above. Do this in such a way that a through-
going slot is the result.
To dismantle the saw table, proceed in reverse
order.
7.2. Tensioning the blade (Figure 6)
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 (26) in a clockwise direction.
The correct blade tension can be 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 (26) very slightly (approx.
1-2 mm).
IMPORTANT! The blade may break if the
tension is too high. BEWARE OF INJURY! If the
tension is too low, the powered blade pulley (7)
will spin while the blade does not move.
7.3 Adjusting the blade
CAUTION! The blade tension has to be set
correctly before you can adjust the blade.
Undo the fasteners (13) and open the side cover
(12).
Undo the toggle fasteners (13) and open the left
side cover (12).
Slowly turn the upper blade pulley (8) clockwise
by hand. The blade (26) should run in the middle
of the pulley. If it does not, you will have to adjust
the tilt of the upper blade pulley (8).
If the blade (26) tends to run to the back of the
blade pulley (8), i.e. towards the machine frame
(25), turn the setting screw (22) anti-clockwise
while turning the blade pulley (8) by hand until
the blade (26) runs in the middle.
If the blade (26) tends to run to the front edge of
the blade pulley (8), turn the setting screw (22) in
a clockwise direction.
After setting the upper blade pulley (8) you need
to check the blade (26) position on the lower
16:37 Uhr Seite 19
blade pulley (7). The blade (26) should run in the
middle of the blade pulley (7), as above. If it does
not, you will have to adjust the tilt of the upper
blade pulley (8) again.
Turn the upper blade pulley several times until
the adjustment to the upper blade pulley (8) has
an effect on the blade position of the lower blade
pulley (7).
After any adjustments have been carried out, the
side covers (12) must be closed again and re-
secured with the fasteners (13).
7.4. Setting the blade guide (Fig. 7 - 10)
Whenever you change the blade you must re-set
both the support bearings (30 + 31) and the guide
pins (28 + 29).
Undo the fasteners (13) and open the side cover
(12).
7.4.1. Upper support bearing (30)
Undo the screw (33).
Move the support bearing (30) so that it is no
longer touching the blade (26). There should be
a maximum gap of 0.5 mm.
Re-tighten the screw (33).
7.4.2. Adjusting the lower support bearing (31)
Dismantle the saw table (15).
Swing the blade guard (34) away.
Adjust in the same way that the upper support
bearing was adjusted.
The blade (26) is only supported by the support
bearings (30 + 31) during cutting. When idle the
blade should not touch the ball bearing.
7.4.3. Adjusting the upper guide pins (28)
Undo the Allen screw (35)
Move the mount (36) of the guide pins (28) so
that there is a gap of approx. 1 mm between the
front edge of the guide pins (28) and the gullet of
the blade in front.
Re-tighten the Allen screw (35).
CAUTION! The blade will be rendered useless if
the teeth touch the guide pins while the blade is
running.
Undo the Allen screws (37).
Move the guide pins (28) towards the blade so
that there is a gap of approx. 0.5 mm between
the guide pins (28) and the blade (26). The blade
must not jam.
Re-tighten the Allen screws (37).
