Part I: General Safety Rules
Safety for Children and Pets
WARNING
Tragic accidents can occur if the operator is not alert to the presence of children and pets.
Children are often attracted to the machine and the grinding activity. Never assume that children will
remain where you last saw them. Always follow these precautions:
A. Keep children and pets at least 50 feet from the working area and ensure they are under the watchful
care of a responsible adult.
B. Be alert and turn the machine off if children or pets enter the work area.
C. Never allow children to operate the Stump Grinder.
Safety with Gasoline -
WARNING
Gasoline is a highly flammable liquid. Gasoline also gives off flammable vapor that can be
easily ignited and cause a fire or explosion. Never overlook the hazards of gasoline. Always follow these
precautions:
A. Never run the engine in an enclosed area or without proper ventilation as the exhaust from the engine
contains carbon monoxide, which is an odorless, tasteless, and a deadly poisonous gas.
B. Store all fuel and oil in containers specifically designed and approved for this purpose and keep away
from heat and open flame, and out of the reach of children.
C. Replace rubber fuel lines and grommets when worn or damaged and after 5 years of use.
D. Fill the gasoline tank outdoors with the engine off and allow the engine to cool completely.
Don't handle gasoline if you or anyone nearby is smoking, or if you're near anything that could cause it
to igniteorexplode. Reinstall the fuel tank cap and fuel container cap securely.
E. If you spill gasoline, do not attempt to start the engine.Move the machine away from
the area of the spill and avoid creating any source of ignition until the gas vapors have dissipated. Wipe
up any spilled fuel to prevent a fire hazard and properly dispose of the waste.
F. Allow the engine to cool completely before storing in any enclosure. Never store a machine that
has gas in the tank, or a fuel container, near an open flame or spark such as a water heater, space
heater, clothes dryer or furnace.
G. Never adjust or repair with the engine running. Shut down the engine, disconnect the spark plug
wire, keeping it away from the spark plug to prevent accidental starting, wait 5 minutes before
adjusting or repairing.
H. Never tamper with the engine’s governor setting. The governor controls the maximum safe operation
speed and protects the engine. Over-speeding the engine is dangerous and willcause damage to the
engine and to the other moving parts of the machine.If required, see your authorized dealer for engine
governor adjustments.
