SUPPORT BEARINGS
ADJUSTMENT
The guide bearings (beside) and thrust
bearing (behind) the blade, support the
blade to move in a straight line during
cutting operation. Properly adjusted support
bearings play an important role in getting
accurate cuts.
TO ADJUST THE UPPER AND LOWER
THRUST BEARINGS:
Disconnect the cord from the power source.
Make sure the blade is tracking and
tensioned properly.
For the upper thrust bearing, loosen the
thumb screw and for the lower blade guide,
loosen the set screw. See figure-15.
Figure-15 Upper and lower thrust bearings
Slide the adjustment shafts so that the
blade is positioned in the middle of the
thrust bearings.
The thrust bearings are mounted on
concentric shafts. When the shaft is rotated,
the relative position of the bearing to the
back of the blade can be changed.
Rotate the adjustment shaft so the thrust
bearing just clears the back of the saw
blade.
Once the thrust bearing is in correct
position tighten thumb screw.
Loosen the socket head screw with a
wrench and adjust the entire assembly back
or forth to just clear the back of the saw
blade. Tighten screw, then fine tune it by
adjusting the bearings as mentioned above.
Secure the upper thrust bearings by
tightening the thumbscrew and the lower
one by tightening the set screw.
GUIDE BEARINGS
ADJUSTMENT
The guide bearings are positioned beside
the blade.
TO ADJUST THE GUIDE BEARINGS:
Disconnect the cord from the power source.
Make sure the blade is tracking and
tensioned properly.
For the upper guide bearings, loosen the
two thumb screws and for the lower guide
bearings, loosen the two set screws. See
figure-16.
