3. Set throttle to (START ) DISENGAGE position.
4. Start engine.
5. Allow engine to warm up at idle for two minutes.

7. Swing the cutting blade to one side, then lower it approximately 1/2” to 1” into the front-
top corner of the stump. Swing the cutting blade back and forth, lowering the cutting
blade approximately 1/2 “to 1” before each sweep, until you have removed the front por-

sweep.

sweep, cutting 1/2” to 1” depth of stump with each sweep.
13. Continue cutting until top level of stump is all removed, making sure not to cut stump
deeper than ground level during this first stage.
14. Turn throttle to the (START) DISENGAGE position, wait ten seconds for blade to stop rotat-
ing then release brake and retract machine from stump.
