Controls & Operation

Starting the Engine: Place on level ground. Set choke, press primer bulb (if equipped), pull starter cord firmly.

1. Pre-Start Check: Ensure area is clear, depth regulator set, clutch disengaged.
2. Starting: Set throttle to idle, pull starter until engine fires. Move choke to run position.
3. Engaging Tines: With engine at operating speed, squeeze clutch lever to engage tines.
4. Adjusting Depth: Use depth lever to raise/lower tines. Start shallow, then increase depth.
