Adjusting Blade Tension - Delta 28-195 Instruction Manual

OPERATING CONTROLS AND ADJUSTMENTS
STARTING AND
STOPPING SAW
The switch (A) Fig. 17, is located on the front side of the
band saw. To turn the saw "ON" move the switch (A) to
the up position.To turn the saw "OFF" move the switch
(A) to the down position.
LOCKING SWITCH
IN THE "OFF" POSITION
IMPORTANT: When the machine is not in use, the
switch should be locked in the "OFF" position to prevent
unauthorized use. This can be done by grasping the
switch toggle (B) Fig. 18, and pulling it out of the switch,
as shown. With the switch toggle (B) removed, the
switch will not operate. However, should the switch
toggle be removed while the machine is running, the
switch can be turned "OFF" once, but cannot be
restarted without inserting the switch toggle (B).
ADJUSTING
BLADE TENSION
1. With the saw blade centered on the two band saw
wheels, turn the tension adjustment knob (A) Fig. 19,
clockwise to increase blade tension or counterclockwise
to decrease blade tension.
2. Blade tension can be checked by pushing on the
blade midway between the two band saw wheels. The
blade should move slightly with average finger pressure.
NOTE: Do not over tension the blade. Too much tension
may cause blade breakage. Too little tension may cause
the blade to slip on the wheels.
3. A series of graduation numbers (1 though 5) shown
at (B) Fig. 19, can be used as reference points in
determining proper blade tension for different width
blades. These graduations will be accurate for average
work and are not affected by re-brazing of the saw
blade. You should use these graduations until you have
become familiar enough with the operation of the band
saw to vary the tension for different kinds of blades or
work. Over tensioning is a common cause of blade
breakage and unsatisfactory blade performance.
4. When the band saw is not in use, it is good practice
to release tension to prolong the life of the blade and to
prevent the blade from taking a set in the band saw
wheels.
5. NOTE: Wider blades need more tension than narrow
blades.
