Summary of Important Safety Information (cont’d) 

 

 

 

27 

 

Cooling ventilation

.  The grinder needs adequate, unobstructed flow of air to allow for proper cooling of engine and 

grinder head. Do not allow debris to accumulate and block airflow. 

 

Transporting

.  During transporting, take precautions to make sure stump grinder will not tip over and cause a fuel 

leak hazard. 

 

Hot exhaust - fires

.  Exhaust from engine can be extremely hot and cause fire.  Position muffler at least 2 meters 

from combustible objects during operation. 

 

Fire extinguisher

. Keep a fire extinguisher rated “ABC” by the National Fire Protection Association nearby is always 

recommended when using gasoline operated machinery.  Keep it properly charged and be familiar with its use.   

 

Personal Protective Equipment 

 

Hearing protection

.  The use of ear plugs or other hearing protection device is recommended for those in close 

proximity to the grinder while it is operating.

 

 

 

Eye protection

.  Wear EN166 1F eye protection when operating the grinder. 

 

Face protection

.  A helmet with a full face visor or mesh visor with protective glasses is recommended. 

 

Loose/dangling

.  Loose or dangling apparel, jewelry or hair can become entangled in moving parts.  Never wear 

jewelry or loose-fitting clothing when operating the grinder. 

 

 

Long pants.  

Wear long, heavy-duty pants to protect legs from ejected materials.

 

 

 

Gasoline Safety 

Gasoline is highly flammable and explosive.  You can be burned or seriously injured when handling fuel.  Use extreme 
care when handling gasoline: 

 

Fuel outdoors

.  Fill fuel tank outdoors – never indoors.  Gasoline vapors can ignite if they collect inside an enclosure.  

Explosion can result. 

 

Use approved container

.  NEVER pump fuel directly into engine at gas station.  Static charge can build and ignite 

fuel.  Use an UL approved fuel container to transfer gas to the engine. 

 

Running/hot engine

.  A running engine is hot enough to ignite fuel.  Never add fuel or remove gas cap if engine is 

running or still hot.  Stop the engine and allow cooling at least 2 minutes before adding fuel. 

 

Heat/flames/sparks

. Keep sources of heat, flame or sparks away while adding fuel. 

 

Don’t fill to the top.

 DO NOT overfill the gas tank.  Allow at least 2.5 cm of empty space below the fill neck to 

allow for fuel expansion and operation on slopes. 

 

Don’t fill to the top

.  DO NOT fill the gas tank to the top.  Gasoline may spill when operating on a slope. 

 

Replace cap

.  Replace gas cap securely before starting engine. 

 

Spills

.  Clean up fuel spills immediately.  Move grinder away from spilled fuel on the ground.  Wipe fuel off engine 

and wait 5 minutes for excess fuel to evaporate before starting engine.  Gas soaked rags should be disposed of 
properly. 

 

On skin/clothes

.  If gasoline is spilled on your skin or clothes, change clothes and wash skin immediately. 

 

Inspect fuel system

.  Check fuel system on a regular basis.  Look for signs of leaks, deterioration, chafed or spongy 

fuel hose, loose or missing fuel hose clamps, damaged fuel tank or a defective fuel shut-off valve.  Do not start 
grinder until needed repairs have been completed. 

 

Gasoline storage

.  Store gasoline in a cool, dry place in an UL-approved, tightly sealed container away from 

children. 

 

 

Safety – During Use 

 

Safety equipment/controls

.  Always operate the grinder with all safety covers, guards, and barriers in place and in 

good working order and all controls properly adjusted for safe operation. 

 

Controls

.  Stay in the OPERATOR POSITION while actuating controls.  

 

Know how to stop

. Know how to stop the grinder quickly if needed by releasing the operator presence bar.  If this 

does not work, do the following in order until unit is stopped. 1.) Push the stop button on the control panel.  2.) Use 
ON/OFF switch on engine (or ignition switch on electric start models).  3.) Engage full choke by flooding the engine.  

 

Kickback

.  Machine can experience significant “kickback” when operating or first coming into contact with the 

stump.   

 

Slipping/falling

.  Operating in wet or icy conditions could lead to losing your footing and slipping or falling.   

 

Damaged

.  Do not operate the grinder with damaged, missing, incorrectly adjusted or broken parts. 

 

Check for gas leak before starting.

  After opening gasoline valve, smell for gas before starting engine.  If you smell 

gas, DO NOT start engine.  DO NOT light a match.  DO NOT flip on an electrical switch.  Exit area immediately and 
call fire department.
