Protecting Yourself and Those Around You
WARNING
This is a high-powered machine, with moving parts operating with high energy. You must operate the
machine safely. Unsafe operation can create a number of hazards for you, as well as anyone else in the
nearby area. Always take the following precautions when using this machine:
W W W . T M G I N D U S T R I A L . C O M P 0 5 / 2 6 T o l l F r e e : 1 - 8 7 7 - 7 6 1 - 2 8 1 9

A. Keep in mind that the operator or user is responsible for accidents or hazards occurring to other
people, their property, and themselves.
B. Always wear protective goggles or safety glasses with side shields while using the Wood Chipper
to protect your eyes from possible thrown debris.
C. Avoid wearing loose clothing or jewelry, which can catch on moving parts.
D. We recommend wearing gloves while using the Wood Chipper. Be sure your gloves fit properly and
do not have loose cuffs or drawstrings.
E. Wear shoes with non-slip treads when using your Wood Chipper. If you have safety shoes, we
recommend wearing them. Do not use the machine while barefoot or wearing open sandals.
F. Wear long pants while operating the Wood Chipper.
G. Keep bystanders at least 50 feet away from your work area at all times. Stop the engine when
another person or pet approaches.
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 chipping 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 Wood Chipper.
Safety with Gasoline - Powered Machines
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
ignite or explode. 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 make adjustments or repairs 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 making adjustments or repairs.
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 will cause
damage to the engine and to the other moving parts of the machine. If required, see your
authorized dealer for engine governor adjustments.
I. Keep combustible substances away from the engine when it is hot.
J. Never cover the machine while the muffler is still hot.
K. Do not operate the engine with the air cleaner or the carburetor air intake cover removed. Removal
of such parts could create a fire hazard. Do not use flammable solutions to clean the air filter.
L. The muffler and engine become very hot and can cause a severe burn; do not touch.
