towbar
Remember to follow these steps when towing:
1. Lock the towbar coupler before towing and connect the safety chains.
2. Ensure that the ball is fully inserted into the coupler.
3. If necessary, use the adjustment nut inside the coupler to adjust the ball locking flange.

CHUTE LATCHES
Inspect all latches and pin lock when chutes are closed
toolbox

cutting drum
blades
Flip reversable blade to new edge or replace when dull. DO NOT SHARPEN. Changing the cut angle and the cutting edge temper will reduce the performance of the tornatic machine and reduce blade life. Use ONLY OEM Blades available on Bigbear Power Parts Store. Always wear thick gloves when changing these razor sharp blades.
Use red loctite on the bolt threads and torque to 70-100 FtLbs
drum jams
Hey there! Just a friendly reminder to run the drum clean before turning off the machine. Make sure to clear out any chips and branches from the drum and feed chutes. If there are any stubborn jams, you remove the drum shaft cover and with the provided drum shaft tool turn the drum shaft counterclockwise to remove the chips. To help the chips slide out, you can spray some WD40 under the drum, but avoid using water as it can cause the chips to swell. Remenber to run the drum clean before shutdown and everything keeps running smoothly!
CUTTING ANVIL
Replacing and flipping blades requires no adjustment to the cutting anvil. In the event you replace the anvil, set the cutting gap to 1/16 inch before tightening all the anvil bolts.
