Cog Belt
To replace the cog belt ( Figure 12 ), loosen
the phillips screws on the belt cover and
set the belt cover aside. To remove the
belt, turn the belt and pull it off the pulley at
the same time. To install the belt, place the
belt over the large pulley first, then pull and
turn the belt onto the smaller pulley.
Motor Brushes
To replace the motor brushes, loosen the
phillips screws on the vented motor cover
and set the motor cover aside. Remove the
brush holders and brushes, and replace
with new ones as shown in
Figure 13 .
12. Using an allen wrench, adjust the set
screws in the cutterhead (
Figure 10 )
until the blade edge just touches the
straightedge (
Figure 11 ) . Note–If the
blade edge is set lower than the out-
feed sole, the end of the workpiece will
not pass smoothly onto the outfeed
sole. If the blade edge is set higher
than the outfeed sole, accurate planing
results will not be achieved.
13. The edge of the outfeed and infeed
soles should be aligned with the edge
of the blade. Adjust if necessary.
14. Using the open-end wrench, tighten
the 3 gib bolts to secure the blade
holder into position.
15. Recheck the blade holder alignment
and blade height using a straightedge,
16. Repeat the blade changing process for
the second blade.
