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 sharp-
ened 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 only refers to 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.
Dismantling
Dismantle the bandsaw blade as follows:
1. Remove the guards over the band wheels.
2. Loosen the right-hand band wheel by crank-
ing about 10 turns anticlockwise.
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. 76. 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.
