Perform previous Checking Wheel
Alignment procedure, beginning on Page
63, and adjust wheels as necessary make
them parallel and coplanar.
Tip:
The first time you get the wheels
coplanar, place a mark on each wheel where
you held the coplanarity gauge, then use this
position again in the future if you need to
repeat the procedure. This assures repeated
accuracy every time you adjust the wheels.
— If no further adjustments are necessary,
remove blade, re-install table, and then
re-install blade.
— If the lower wheel is tilted in relation to
the upper wheel, proceed to Adjusting
Lower Wheel Shaft Position.
Shimming a Wheel
When the wheels are parallel but not coplanar,
one of the wheels must be shimmed out to bring
it into the same plane as the other wheel.
Tip:
Standard washers work well for shimming a
wheel because they can easily be stacked to get the
desired height.
To shim a wheel:
1.
DISCONNECT
MACHINE FROM POWER!
2.
Adjust upper wheel tracking so that it is
parallel with lower wheel.
3.
With coplanarity gauge touching both rims of
wheel that does not need to be shimmed out,
measure distance away from other wheel
with a fine ruler (see Figure
106). The
distance measured with ruler is distance this
wheel must be shimmed.
4.
Remove
blade.
5.
Remove wheel to be shimmed. Place as many
shims as necessary to correct gap measured
in Step 3 onto wheel shaft.
6.
Re-install and secure wheel.
7.
Re-install blade (refer to Changing Blade
on Page 43) and properly tension and track
blade.
Adjusting Lower Wheel Shaft
Position
If the lower wheel is tilted in relation to the
upper wheel, perform the following procedure to
make it coplanar with the upper wheel.
There are four adjustment bolts with hex nuts
in the lower wheel adjustment hub, shown in
Figure
107. These adjust the wheel tilt from
side to side and up and down.
Note:
If you make a mistake during the following
procedure, it can be very difficult to correct.
Therefore, it is important to double check wheel
alignment (see Page 63), and troubleshoot all
other possible solutions (see Troubleshooting)
prior to adjusting the lower wheel shaft position.
