2. Continue to pull up on the tension assembly until it
has moved two or three notches above where the
blade first straightened out. Engage the teeth on
the catch into the notches. This is the proper ten­
sion for a 1/4" blade.
NOTE: If using an 1/8" blade the tension assembly
should be positioned one to two notches above the
point where the blade first straightened out.
3. Tighten the tension lock knob in order to hold the
tension assembly in place.
NOTE: Over tensioning of blade can cause excessive
wear of wheel bearings and motor and shorten blade
life.
WARNING: Push the on-off knob off, lock with a
padlock, and unplug before making any adjust­
ments.
TRACKING THE BLADE
Blade tension must be properly adjusted before
tracking the biade.
1. Slowly turn the upper wheel clockwise by hand
and watch the blade on the tire. If the blade moves
away from the center of the tire the tracking will
have to be adjusted.
2 . Insert a 1/8" hex wrench into the tracking adjust­
ment screw located on the back of the saw behind
the upper wheel.
3. a. If the blade moved toward the front of the saw
turn the adjustment screw in (clockwise) while
turning the wheel by hand, until the blade rides
in the center of the tire.
b. If the blade moved away from the front of the
saw turn the adjustment screw out (counter
clockwise) while turning the wheel by hand, until
the blade rides in the center of the tire.
4. Check the position of the blade on the other tires.
The blade should be completely on the tire. If not,
adjust the tracking until the blade is on all three
tires.
5. Rotate the upper wheel by hand in a clockwise
direction for a few more turns. Make sure the blade
stays in the same location on the tires. Readjust if
necessary, until blade is tracking properly.

ADJUSTING THE BLADE GUIDES AND
BACK-UP BEARING
NOTE: The upper and lower blade guides and back­
up bearings support the band saw blade during cut­
ting operations. The adjustment of the guides and
bearings should be checked whenever a different
blade is installed.
1. Adjust the back-up bearing first. Loosen the rear
set screw using a 1/8" hex wrench. (This set screw
is located on the right side of the upper slide for
the upper bearing and on the right side of the
frame just below the table for the lower bearing.)
2. Move the back-up bearing to within 1/32" of the
blade. Tighten the rear set screw. Repeat on the
other back-up bearing.
NOTE: The back-up bearing is to support the back
edge of the blade while cutting. The blade should not
contact the bearings when you stop cutting.
Adjust the position of the blade guide support next.
Loosen the front set screw using a 1/8" hex
wrench. (This set screw is located on the left side
of the support for the upper guides and the right
side for the lower guides.)
Slide the blade guide support on the shaft until the
front edge of the blade guides are about 1/32"
behind the gullet of the blade. Tighten the set
screw. Repeat for the other guide.
