Figure 19. Support bearing components.
To adjust the support bearings:
1. Loosen the lock bolt approximately
1
⁄4 turn.
Note—If you loosen the lock bolt too much,
the support bearing will fall out of place.
2. Turn the adjustment shaft until the support
bearing is positioned approximately 0.016"
behind the back of the blade. Use a feeler
gauge or four thicknesses of a dollar bill to
check this.
3. Tighten the lock bolt, and repeat with the
other support bearing.
4. Test the adjustment of the support bearings
by spinning the wheels by hand, at full blade
tension, in the same direction of operation.
While you are spinning the wheels, the sup
-
port bearings should not turn. (The support
bearings should only turn during cutting
operations.)
Support Bearing

blade to brace it from pushing backwards during
a cut.

ponents to clarify the adjustment instructions.
