Tensioning/changing the saw blade
Procedure for exchanging the saw blade:
Disconnect machine from the power supply.
Loosen the two screws M6x20 (S) and nuts (N).
Remove the u-shaped clamp (C) from the worktable.
Open the upper and lower front door (F).
Release the saw blade tension with the hand wheel
(H).
-
Turn the hand wheel counter-clockwise: the band
saw blade tension is reduced.
-
Turn hand wheel clockwise: the band saw blade
tension is increased.
Unthread the old band saw blade through the work
table and the table insert.
ATTENTION:
For this purpose use cut-proof gloves!
Thread the new saw blade (SB) into the work table
and into the table insert.
In the next step, place new saw band (SB) in the
bearings (B) of the saw band guide, then place it in
the middle of the rubber tracks of the two band saw
wheels (W).
ATTENTION:
note the cutting direction! The teeth of
the band saw blade must point downwards in the
cutting direction and towards the front of the machine.
Tension the band saw blade with the hand wheel
(H).
Close the upper and lower front door (F).
Mount the clamp (K) back on the worktable using
two M6x20 screws (S) and two nuts (M).
To check whether the band saw blade is correctly
positioned in the rubber bands of the two band saw
wheels (W), let the machine run for at least one
minute; stop the machine, open the upper and lower
front doors and check the settings and, if necessary,
readjust the band saw blade run using the hand
wheel for band saw blade tracking adjustment (see
paragraph 16.4).
Adjust the saw band guide.
NOTICE
The saw band tension must be
adjusted according to the saw band
width.
