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:
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

Part I: General Safety Rules
safety shoes, we recommend wearing them. Do not use the machine while
barefoot or wearing open sandals.
F. Wear long trousers 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 Petrol Powered Machines
WARNING
Petrol is a highly flammable liquid. Petrol also gives off flammable vapor that can
be easily ignited and cause a fire or explosion. Never overlook the hazards of petrol.
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 petrol tank outdoors with the engine off and allow the engine to cool
completely. Don't handle perol 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 petrol, 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 petrol in the tank, or a fuel container, near an open
flame or spark such as a water heater, space heater, clothes dryer or furnace.

Part I: General Safety Rules
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 exhaust 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 exhaust and engine become very hot and can cause a severe burn; do not
touch.
