about how to safely use your grinder. 

 

   WARNING 

 

Carefully read and make sure you understand the following safety information before using 
the grinder.  Improper use or maintenance of the grinder can result in 

serious injury or 

death

 

from 

fire/explosion, carbon monoxide poisoning, lacerations, entanglement or 

burns

.  

Damage can also occur to windows, siding, vehicles and bystanders from chips and 

debris which can become projectiles.

 

 

 

General 

 

Read manual.

  Read this Owner’s Manual and the engine Owner’s Manual completely before attempting to use and 

service the grinder

.  

Serious injury or death can result if safety instructions are not followed. 

 

Instruct operators

. The grinder owner or rental company must instruct all operators in safe grinder set-up and 

operation.  Do not allow anyone to operate the grinder who has not read the Owner’s Manual and been instructed on 
its safe use. Make sure Owner’s manual is within the attached storage tube on the grinder. 

 

Adults only.

  Only trained adults should operate and service the grinder.  Do not let children operate.  

 

Under the influence

.  Never operate, or let anyone else operate, the grinder while under the influence of alcohol, 

drugs or medication. 

 

Intended use

.  Carefully read about and understand the intended use of this grinder. Do not use for other purposes, as 

unforeseen hazards or equipment damage may result. 

 

Controls and safety labels

.  Learn how to use the machine and its controls safely.  Understand and follow all safety

Know how to operate.  

Be thoroughly familiar with all controls and with the proper use of the equipment.  Know 

how to stop the grinder quickly if needed. 

 

Utility marking.

  Call your local utility company to request marking utilities 3 days before stump grinding. Trees can 

grow on top of and around underground wiring that was installed many years before a tree was planted. 
 

Getting Ready 

 

Flying debris

. Clear area of objects such as stones, toys, steel wire, etc. that could become caught in moving machine 

parts and ejected as a projectile. 

 

Operate OUTSIDE only – dangerous carbon monoxide exhaust

!  Grinders give off carbon monoxide exhaust, a 

poisonous gas that can kill.  You CANNOT smell it, see it or taste it.  ONLY run grinder OUTDOORS and at least 20 
feet from the home, away from windows, vents and air intakes, to allow proper ventilation. If you start to feel sick, 
dizzy, or weak while using the grinder, shut off the engine and get to fresh air RIGHT AWAY.  NEVER run grinder 
engine inside homes, garages, sheds or other semi-enclosed spaces.  These spaces can trap poisonous gases.
