Assembly and adjustments
Blade tension adjustment (Fig. 11)
A change in blade width or type of material being cut will
affect the blade tension. If the blade tension is too loose,
the blade may slip on the wheels. If the blade is too
tight, the blade may break.
1. Turn the blade tension knob
(1)
clockwise, to raise
the upper blade wheel
(2)
and increase the tension
on the blade. The blade should be tight on the wheel,
but do not overtighten the blade.
2. Turn the blade tension knob
(1)
counterclockwise to
lower the upper blade wheel
(2)
and reduce the
tension on the blade.
Blade tracking adjustment (Fig. 11 and 12)
Check for proper blade tension before making any
blade tracking adjustments.
1. Rotate the upper blade wheel
(2)
clockwise and
check the position of the blade on the wheel. The
blade should remain in the center of the wheel.
a. If the blade moves toward the front of the wheel,
loosen the blade tracking lock knob
(4)
and turn the
blade tracking knob
(3)
slightly clockwise. At the
same time, turn the upper wheel
(2)
until the blade is
centered.
b. If the blade moves toward the back edge of the
wheel, turn the blade tracking knob
(3)
slightly
counterclockwise. At the same time, turn the upper
wheel
(2)
until the blade is centered.
2. Tighten the blade tracking lock knob
(4)
when you are
finished making adjustments.
3. Check the position of the blade on the lower wheel. If
the tracking is off, continue adjusting the blade until it
sits properly on both wheels.
