instructions below.
BLADE TRACKING ADUSTMENT
First, inspect the blade wheels for wear or damage and repair as required, Blade tracking adjustment should always begin
at the wheel where the tracking is farthest out of specification. Using the instructions below, adjust the worst wheel, jog the
blade and recheck both wheels. Repeat this process until both wheels are within specification.
Idler Wheel Adjustment
The Idler Wheel must be adjusted so that it is aligned with the drive wheel. The purpose of the adjustment is to ensure
that the back of the blade remains about .040-.080” away from the wheel flange during rotation.
