Adjust the scale of the splitter
Tighten the fixing screw when the adjustment is
correct. The adjustment can be checked by
setting the splitter holder to a thickness and then
by sawing a test piece. When the adjustment is
correct, the thickness of the specimen will
correspond to the setting of the splitter content.
holder.
Slide the splitter
holder against the
blade along the rail.
Then move the scale
(B-Fig.11) sideways
and adjust the zero
size with the line on
the magnification
window (Fig.11).
Adjust the saw height
Release the blade
guide lock knob
(fig.12) and turn the
crank handle (fig.12)
to raise or lower the
upper blade guide to
the desired height.
Then the lower edge
of the blade guide is
approximately 3.5 cm
above the upper surface of the workpiece.
Change speed of the saw blade
WARNING! Before
changing speed,
always make sure
that the machine is
disconnected from
the power supply.
This band saw has
two blade speeds,
low speed and high
speed. The lower belt
wheel (A-Fig.13) has two integrated
multi-v-shaped pulleys and the motor shaft has a
double multi-v-shaped pulley (B-Fig.13). The multi-v
belt (C-Fig.13) passes around the belt pulley and
the engine pulley. The belt tension is released and
tightened using the crank handle (D-Fig.13). For
high speeds, the belt must be mounted on the rear
pulley on both the motor and the pulley. See fig. 13.
For low speed, the belt must be mounted on the
front pulley on both the motor and the pulley.
See Fig. 13
Replacing the band saw blade
WARNING!
Disconnect the
machine from the
power supply. This
ensures that the
band saw will not be
switched on
temporarily if
someone accidentally
accesses the ON /
OFF switch.
a) Open the upper and lower crawler doors by
turning the lock knob.
b) Remove the splitter contents from the front of
the worktable by loosening the four screws (fig.3)
c) Release the blade tension by turning the quick
release lever (fig.14) clockwise.
d) Remove the saw blade by inserting it through
the groove in the table, the upper and lower blade
guides and the slot in the back of the machine
(Be careful not to cut yourself. Wear gloves if
necessary).
e) When mounting the new blade, the blade teeth
should point downwards and towards you in that
position the blade passes through the table.
f) Tighten the new blade again by turning the quick
release lever (Fig.14) counterclockwise and
by checking the tracking. The blade should rotate in
the centre of the belt wheel.
g) Reset the blade guides as described in the ”blade
guide”.
h) Reset the blade tension as described in the
section ”Adjusting the blade tension”.
i) Put back the splitter holder and unscrew the 4
screws (fig.3).
back of the blade
by unlocking the
hex nut (C-Fig. 9).
When the correct
setting is reached,
lock the pressure
bearing in position
with the hexagon nut
(A-Fig.9).
Lower controls:
To adjust the lower blade guides, first, loosen the
hexagon nut (A-Fig.10) and then move the guide
carrier to approx. 0.15 cm behind the saw blade
tooth gaps and tighten the hex nut (A-Fig.10). Then
adjust the rollers to within 0.08 cm of the blade by
loosening the screw (B-Fig.10) on each side of the
blade. Finally, adjust the pressure bearing to be
absolutely free from the back of the blade by
unlocking the hex nut (C-Fig.10).
