Assembly And Adjustments - Skil 3386 Operating/Safety Instructions Manual

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,
it will be difficult to cut a straight line. If the blade is too
tight, the blade may break or come off the wheel.
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) counter-clockwise to
lower the upper blade wheel (2) and reduce the
tension on the blade.
Blade tracking adjustment (Fig. 11 & 12)
Note: The band saw blade tracking is pre-set at the
factory. Check for proper blade tension before making
any blade tracking adjustments.
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.
If an adjustment is needed:
1.Using a wrench, loosen the blade tracking lock
nut (3).
2. If the blade moves toward the front edge of the
wheel: turn the blade tracking knob (4) slightly
clockwise. At the same time, turn the upper wheel (2)
until the blade is centered.
If the blade moves toward the back edge of the
wheel: turn the blade tracking knob (4) slightly
counter-clockwise. At the same time, turn the upper
wheel (2) until the blade is centered.
3. Tighten the blade tracking lock nut (3) when you are
finished making adjustments.
4. 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. If blade does not sit
properly on wheels, return to blade tension
adjustment.
Blade guide adjustment
The upper and lower blade guides and support bearings
(located above and below the table) keep the blade
moving in a straight line during operation. These guides
must be checked and adjusted before each use, after
changing the blade, and after blade tension and tracking
adjustment.
Note: Make sure the blade tension and tracking are
properly adjusted before adjusting the upper and lower
blade guides.
