Wheel Alignment Test - Shop fox W1729 Owner's Manual

Model W1729 (For Machines Mfd. Since 1/12)
Wheel.Alignment.Test
Wheel alignment is an important adjustment to maintain.
When the wheels are "coplanar" with each other, they
are parallel and aligned, and the wheels automatically
track the blade by balancing it on the crown of the
wheel tire. When this alignment is achieved, the saw
will operate at a maximum, vibration-free efficiency and
produce smooth cuts.
For this procedure, you will make a simple Coplanarity
Gauge using the dimensions shown in Figure.48.from a
straight high-quality 2x4.
When you use the Coplanarity Gauge, the gauge must
contact the top and bottom of both wheels at the same
time for the wheels to be coplanar (see Figure.47).
After completing the steps on the following page and
finding out what alignment problem exists, use Figure.48
to point you to one or more applicable procedures to
correct any problems with coplanarity.
