5. Operation

5.1 Starting the Engine (Electric Start)

1. Ensure the chipper is on a level surface and the parking brake (if equipped) is engaged.
2. Turn the fuel valve to the 'ON' position.
3. Set the choke lever to the 'CHOKE' position (for cold starts).
4. Insert the ignition key into the switch and turn it to the 'START' position. Release the key once the engine starts.
5. Once the engine warms up (a few seconds), gradually move the choke lever to the 'RUN' position.
6. Allow the engine to run at idle for a few minutes before engaging the chipper.

5.2 Feeding Material

CAUTION: Never place hands or feet into the feeding hopper or discharge chute.

• Ensure the engine is running at full operating speed before feeding material.
• Feed branches and brush into the hopper one at a time, butt-end first.
• Do not force material into the chipper. Allow the machine to pull the material through.
• Avoid feeding material larger than the maximum recommended diameter (5 inches).
• Do not chip material containing metal, rocks, or other foreign objects.
• Adjust the discharge chute direction as needed to direct chips away from the operator and bystanders.
