ADJUSTING THE CARRIAGE BEARINGS See Figures 21A - 21B. Loose carriage bearings permit the blade to wander slightly while cutting, which will result in a poor cut and more wear and tear on the saw. Use the following steps to check for tightness and to then adjust the bearings if needed. [] On the left side of the arm, remove the carriage lock knob, the carriage cover screws, and the carriage cover. [] With one hand, grip the front bearing hard to keep it still, and pull the carriage forward with the other hand. The bearing should turn. if it stays still as the carriage is moved, it needs to be adjusted. CARRIAGESEARING [] Use a 9/16 in. wrench to hold the eccentric screw (top of bearing) and a 1/2 in. wrench to loosen the nut below the bearing. [] Turn the eccentric screw a partial turn as needed to tighten the bearing. [] Retighten the nut and repeat the second step to test the tightness. Adjust it so the bearing turns even against resistance when the carriage is moved - but not so much that the carriage is difficult to move and return it to its rear position. [] Repeat for the left rear bearing. Note: Adjust bearings on the left side only. Bearings on the right side do not adjust. [] Replace the carriage cover, carriage cover screws, and carriage lock knob. ECCENTRICSCREW 9/16 in. WRENCH GRASPAND HOLD CARRIAGESEARING Fig. 21A 1/2 in.

ADJUSTING
THE CARRIAGE
BEARINGS
See Figures 21A
-
21B.
Loose carriage bearings
permit the blade to wander
slightly
while cutting, which will result in a poor cut
and more wear and tear on the saw. Use the following
steps to check for tightness
and to then adjust the
bearings if needed.
[]
On the left side of the arm, remove the carriage
lock knob, the carriage cover screws,
and the
carriage cover.
[]
With one hand, grip the front bearing hard to keep it
still, and pull the carriage forward with the other
hand. The bearing should turn. if it stays still as the
carriage is moved, it needs to be adjusted.
CARRIAGESEARING
[]
Use a 9/16 in. wrench to hold the eccentric
screw
(top of bearing) and a 1/2 in. wrench to loosen the
nut below the bearing.
[]
Turn the eccentric
screw a partial turn as needed to
tighten the bearing.
[]
Retighten the nut and repeat the second
step to
test the tightness. Adjust it so the bearing turns
even against resistance
when the carriage is
moved - but not so much that the carriage is difficult
to move and return it to its rear position.
[]
Repeat for the left rear bearing.
Note: Adjust bearings on the left side only. Bear-
ings on the right side do not adjust.
[]
Replace the carriage cover, carriage cover screws,
and carriage lock knob.
