MAINTENANCE
Bandsaw Blade
WARNING!
The bandsaw blade is sharp and
can cause cuts. Warning for
personal injury. Wear protective
gloves whenever you handle the
bandsaw blade.
The bandsaw blade should be set and sharpened
regularly to give optimal performance. During
normal sawing of most species of wood this
should be done at intervals of approx. 2 hours of
effective cutting time. Effective cutting time
refers to only the time that the bandsaw blade
actually works. The bandsaw blade should be
sharpened more frequently when cutting those
species of wood with a high sand content. For
blade sharpening, see the separate instructions
for the Grindlux bandsaw blade grinder.
Dismantling
Dismantle the bandsaw blade as follows:
1. Remove the guards over the band wheels.
See page 21.
2. Loosen the right-hand band wheel by
cranking about 10 turns counter-clockwise.
3. Carefully remove the bandsaw blade.
Cleaning and inspection
Clean sawdust and any coating from the bandsaw
blade. Now check whether there are any cracks
(A) in the gullets. Small cracks can be ground
away when sharpening the bandsaw blade. If the
cracks are so large that they cannot be ground
away, the bandsaw blade should be discarded.
Cracks in the gullets are the most common cause
of bandsaw blade breakage. The bandsaw blade
can be ground to a minimum width of 24 mm. See
FIG. 54. A new bandsaw blade is 32 mm wide.
The bandsaw blade should be discarded once
any part of it reaches the minimum width.
Setting the Saw
The bandsaw blade’s teeth should be set to the
dimensions shown in the adjoining figure. Every
third tooth should remain unset. The teeth
should be set as follows:
B=Set to the right, 0.4-0.5 mm.
C=Set to the left, 0.4-0.5 mm
D=Not set.
The more accurate the set is made, the straighter
and smoother the bandsaw blade runs when
cutting the log. The bandsaw blade should be set,
at a minimum, after every third sharpening.
WARNING!
Never use a damaged bandsaw
blade.
