deflection when belt is pushed with
moderate force, as shown in
Figure 18.
Note: After the first 16 hours of operation,
re-tension the belt, as it will stretch and seat
during this time, which causes it to lose the
initial tension you set.
15. Tighten motor mount fasteners (see
Figure 15).
16. Re-install fence assembly, including belt
cover.

Alignment
— If pulleys are aligned, proceed to
Step 14.
— If pulleys are not aligned, perform
Steps 12–13.
12. Loosen motor pulley set screw and cutterhead
pulley set screw and align both pulleys. (Use
straightedge if needed.)
13. Tighten set screws and repeat Step 10 to ver-
ify proper pulley alignment. Pulleys should be
parallel and aligned, as shown in
Figure 17,
when belt is properly tensioned.
11. Look down length of belt and pulley faces to
check pulley alignment (see
Figures 16–17).
If available use a narrow straightedge against
pulley faces to check alignment.
