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.  If you have any questions, contact your retail or rental dealer or Dosko

WARNING:  Never attempt to cut on a slope exceeding 15

Exercise caution when cutting stumps on an incline, as the machine may shift or slide unpredictably.  Never 

attempt to cut with the machine uphill or downhill from you as it may slide toward you or you may fall 

toward the machine.  Cut only on a slope from the side.
