7.9 Feed Rollers
The top and bottom feed rollers may occasionally require some
maintenance (for example, removing a jam, cleaning, inspection,
repair, and so on). In order to safely raise and gain access to
the rollers, a turnbuckle has been included with the chipper. (On
BX102R models, the turnbuckle is stored under the feed table
with 2 link pins.)
To raise the upper feed roller:
1. Remove the bridge guard.
2. Remove the tension spring jam nut and hex nut from each
side.

3. Attach the turnbuckle to the attachment points on the
hopper and roller bridge using the two link pins.
