V-belts (D) using light finger pressure.

ADJUSTING SPRING TENSION OF CUTTERHEAD GUARD
The cutterhead guard (A) Fig. 18, completely covers the cutterhead. During
operation the material being jointed or planed pushes the guard out of the way
and at the completion of the cut, the guard springs back over the cutterhead
providing full coverage. If it ever becomes necessary to adjust the spring tension
of the cutterhead guard, loosen two set screws (B) and turn screw (C) clockwise
to increase or counterclockwise to decrease the spring tension. Then retighten
the two set screws (B).
Warning! Before operating jointer, check guard to make sure it functions properly
and quickly returns to the closed position.
