REEL AND REEL DRIVE (continued)
Reel Primary Belt Tension
IMPORTANT: Belt tension increases as reel is
raised. To avoid damaging belt or idler arm, do not
over-tighten belt. Operate at minimum tension
required to prevent slipping.
To adjust:
1. Fully raise reel and engage reel props at each
reel arm. Lower reel onto props.
2. To increase tension, slide channel (A) to
compress spring (B).
3. To decrease tension; push washer (C) against
channel spring (D) to release grip on rod, then
slide channel (A) away from spring (B).
4. Lower reel to check tension. If belt slips in
operation, repeat steps 1 and 2.

Reel Final Drive Belt Tension

Adjust reel final drive belt tension so belt will not
slip when reel is turned backward.
To adjust, move spring handle (D) to different
notches (E).
Rotating handle forward increases belt tension.
