Your Dosko 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 blade 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 23 meters of stump grinding operation. 

 

Protect cars, windows and other objects within 23 meters 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!

:

  

Your stump grinder comes fully assembled and requires only that you add 

engine oil to crankcase, fuel to tank, and a battery.
