Stump and Root Grinder

Your NorthStar grinder is intended for outdoor-use only and can be used to remove many tree stumps

and exposed root systems close to ground level. By moving the wheel in sweeping movements laterally

over the top and front of the stump, you can gradually grind it away. Make sure you completely read

and understand this manual before using the grinder for the first time.

WARNING

READ and UNDERSTAND this manual completely before using the grinder! Failure to properly operate,

and maintain this grinder could result in serious injury or death to the operator or bystanders.

All machines have hazards associated with their operation. This stump grinder has certain special hazards,

which you must be aware of. As an operator or owner you have a duty to be aware of these hazards and know

preventive measures to take to avoid them. When reading this manual pay particular attention to avoiding these

hazards.

In particular, be aware of the following:

Know location of buried electrical and other utility lines.

Do not allow children or untrained adults to operate.

Wear eye protection and other personal protection against flying rocks and debris.

Check that cutter wheel teeth are secured, sharp and not missing.

Do not operate if operator presence bar fails to stop engine upon release.

Make sure no children or bystanders are within 75' (feet) of stump grinding operation.

Protect cars, windows and other objects within 75' from flying debris.

Be prepared for machine “kickback” when initially contacting the stump.

Be aware of potential for carbon monoxide (CO) poisoning.

Prevent fires/explosions from fueling.

Do not attempt to perform adjustments, declog or clean unit while engine is running.

Avoid burns from engine or hot exhaust.

Avoid using in wet or icy conditions where falls may occur.

Details about these hazards are found throughout the manual and are summarized at the end of the manual under

“Important Safety Information.”

STOP!

ADD ENGINE OIL: Your stump grinder comes fully assembled and requires only that you add engine oil to crankcase

and fuel to tank.

INSPECT COMPONENTS: Closely inspect to make sure no components are missing or damaged. See the “Receiving

Your Unit” section for instructions on whom to contact to report missing or damaged parts.
