ADJUSTING BLADE TRACKING
While it's nearly impossible to set a band saw blade to run perfectly true, you
can adjust the tracking so the blade runs as close to centre as possible. If the
blade tracks too close to the front, it could slip off while cutting. If the blade
tracks to the rear of the wheel, it could damage the tire. Keep the blade at
least 1/8" from the front edge.
To adjust the blade tracking, first turn off and unplug the saw. Then confirm
that you have enough clearance between the blade and the upper and lower
bearing assemblies. (See page 11.)
1. Open the upper wheel cover door then rotate the wheel slowly forward by
hand. The blade should remain relatively centered as it turns. See Figure
39.
2. If the blade tracking needs to be adjusted, turn the TRACKING KNOB (A)
on the rear of the saw. See Figure 40.
• Turn the TRACKING KNOB (A) clockwise to tilt the wheel back and move
the blade from front to rear.
• Turn the TRACKING KNOB (A) counter-clockwise to tilts the top of the
wheel to the front and moves the blade from the read to the front.
Turn the knob in half-turn increments, check tracking and adjust again as
needed.
ADJUSTING BLADE GUARD
The BLADE GUARD (B) adjusts to accommodate the height
of the workpiece. To prevent the blade (which is flexible and
which would not otherwise be supported) from slipping out of
position during cutting, and to reduce risks of injuries, expose a
minimum amount of blade.
The blade guard should be set 1/8" to 1/4" above the workpiece
to prevent the blade from flexing out of position or offline
during cutting. See Figure 41.
To adjust the height of the blade guard follow these steps:
1. Make sure the band saw is turned off and the power cord is disconnected
from the power source.
2. Loosen the smaller LOCK KNOB (C) . See Figure 42.
3. Move the blade guide assembly up or down by turning the ADJUSTMENT
KNOB (D) . Then re-tighten the LOCK KNOB (C) .
