8.1
Use smooth, comfortable side to side movements while operating, pivoting the arc on the
locked left hand wheel.
8.2
When it is desired to cut smaller roots, it may be more effective to do so before rather than
after cutting the main stump.
8.3
Should the chip build-up become excessive when cutting, stop the engine, wait for the cutting
wheel to stop rotating, retract the machine from the stump and rake away the chips.

In order to prevent the wheels becoming stuck in the hole. Move the grinder to the other side
of the stump to continue removal or by filling the hole with chips before continuing.
