ADJUSTING THE CARRIAGE BEARINGS
See Figures21A and 215.
Loose carriage bearings permitthe blade to wander
slightlywhile cutting,which will resultin a poor cut
and more wear and tear on the saw. Use the following
steps to check for tightness and to then adjust the
beadngs if needed.
• On the leftside of the arm, remove the carriage
lock knob, the carriage cover screws, and the
carriage cover.
• With one hand, grip the front bearinghard to keep it
still, and pull the carriage forwardwith the other
hand. The beadng shouldturn. If it stays stillas the
carriage is moved, it needs to be adjusted.
CARRIAGE BEARING
• Use a 9/16 in. wrenchto hold the eccentricscrew
(top of beadng) and a 1/2 in. wrench to loosen the
nut belowthe bearing.
• Turn the eccentricscrew a partialturn as needed to
tightenthe bearing.
• Retighten the nut and repeat the second stepto
test the tightness.Adjust if so the bearingturns
even against resistancewhen the carriage is
moved - but not so much that the carriage is difficult
to move and retum it to its rear position.
• Repeat for the left rear bearing.
Note: Adjust bearingson the leftside only. Bearings
on the right side do not adjust.
• Replace the carriage cover, carriage cover screws,
and carriage lock knob.
