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.

TRACKING THE BLADE
Blade tension must be properly adjusted before
tracking the blade.
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.
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.

blade. Tighten the rear set screw. Repeat on the
other back-up bearing.
