TC-12 TREE CHIPPER OPERATING INSTRUCTIONS
3.12 Feeding Chipper with Auto Feed Height
1. Select log RPM on the right control panel.
2. Never enter feed hopper while engine is running.
3. Always stand to the side of the feed hopper while feeding the chipper to avoid being pulled into feed hop-
per by trailing branches, standing to the side of the feed hopper insures access to a safety bar.
4. Cut pieces into manageable sizes. Trying to feed logs too heavy or branches not easily handled by one
operator increases the chances of strains and fatigue.
5. Load trees and limbs so the trunk end of the limb enters rst with crotches and brush after. Once material
has engaged the feed wheels and is advancing, step back from infeed hopper to avoid trailing limbs and
branches.
6. Load end of limb or log onto feed hopper and pass under height sensor. Height sensor will immediately
open feed wheel throat to accept the material and release the top feed wheel to the spring applied down
pressure to close the throat. The diameter of the material being fed will determine how high the top feed
wheel will rise. Once material has engaged the feed wheels and is advancing step back from hopper to
avoid trailing limbs and branches.
3.13 Unplugging Procedure
Always run the chipper at full engine speed. Dull knives can create chunks, and slivers, causing the engine to
lug. This also contributes to the chipper plugging. Follow the steps below if your TC-12 TREE CHIPPER becomes
plugged:
1. Follow the normal shut-down procedure.
2. Open the hinged portion of chipper hood when the disc is NOT turning.
3. Install disc/drum lock pin, and disconnect battery.
4. Open the hinged portion of chipper hood when the disc is NOT turning.
5. Open cleanout door on bottom of chipper housing.
6. Using a raking tool or gloved hands dig the chips out of the chipper housing.
7. If the discharge chute is plugged, use a raking tool to pull out the majority of the chips out of the open end
of chute. Remove chute access located beneath curve in chute. Push/pull chips to clean as needed. Install
discharge chute access cover.
8. NEVER turn the disc when someone is working inside the chipper housing. The chipper disc will turn
hard then loose causing it to turn faster. Injury could result.
9. ALWAYS use a pry bar to turn the disc. NEVER turn by hand!
10. When the chipper disc turns freely, close and secure the chipper hood and close cleanout door. Engine
will not start until this is done.
11. Follow normal start up procedure, engage clutch and throttle to full speed.
12. Insert small branch into feedwheel and check that it discharges properly then resume normal operations.
