INSTALLING BLADE
To replace the blade, the table stud must be removed as
described in "Removing Blade" above.
Although many of the adjustments may not be altered
when the blade is removed, every adjustment should be
checked prior to using a newly installed blade,
Follow safety precautions which should be observed
every time the band saw isturned on,
Make sure the blade teeth are pointing in the correct
direction. Blade teeth must point down° Turn blade in-
side out if necessaryH
Center the blade on the blade wheel. Tension and track
the blade as described in the following sections.
NOTE: Do not use a new blade to complete a
previously started cut,
TENSIONING BLADE
Refer to Figure 4.
Tension blade by turning the handwheel (Key No. 15).
Be sure blade guides are not interfering with the path of
the blade.
Tighten blade until it is properly tensioned, A properly
tensioned blade will ring slightly when back of blade is
plucked, (Like a string on an instrument ,)
NOTE: CHECK THE TENSION OF A NEW BLADE.
ADDITIONAL TENSION MAY BE RE-
QUIRED AFTER A FEW MINUTES OF
OPERATION.
TRACKING BLADE
Refer To Figure 6.
Track the blade after it has been tensioned°
Proper tracking is achieved when drive wheel and idler
wheels are aligned,
The knob (Key No, 16) is used to tilt tracking bracket
(Key No. 6) and align blade wheels,
