GENERAL SAFETY RULES
SPECIAL MESSAGES
Your manual contains special messages to bring at-
tention to potential safety concerns, machine damage
as well as helpful operating and servicing information.
Please read all the information carefully to avoid injury
and machine damage.
NOTE: General information is given throughout the
manual that may help the operator in the operation
or service of the machine.
IMPORTANT SAFETY PRECAUTIONS
Please read this section carefully. Operate the edger
according to the safety instructions and recommenda-
tions outlined here and inserted throughout the text.
Anyone who uses this edger must read the instructions
and be familiar with the controls.
ENGINE SAFETY PRECAUTIONS
Warning Carbon Monoxide Poisoning
All engines contain carbon monoxide in their exhaust.
Carbon monoxide is a deadly, colorless, tasteless, odorless
gas which may be present even if you do not smell or see
any engine exhaust. Levels of carbon monoxide, which can
be deadly, can be present for days in an enclosed area
that has poor ventilation. Any level of carbon monoxide,
if inhaled, can cause headaches, drowsiness, nausea,
dizziness, confusion and eventually death. If you experience
any of these symptoms, seek fresh air and medical attention
immediately.
Preventing Carbon Monoxide Poisoning
• Never run engine indoors.
• Never try to ventilate engine exhaust indoors. Carbon
monoxide can reach dangerous levels very quickly.
• Never run engine outdoors where exhaust fumes may
be pulled into a building.
• Never run engine outdoors in a poorly ventilated area
where the exhaust fumes may be trapped and not easily
taken away. (Examples include: in a large hole or areas
where hills surround your working area.)
• Always run the engine with the exhaust from the muffler
pointed in the direction away from the operator.
• Never point the exhaust from the muffler towards
anyone. People should always be many feet away from
the operation of the engine and its attachments.
Gasoline Fires and Handling Fuel Safely
Fuel and fuel vapors are highly flammable. Never use fuel
where a spark or flame may be present. Never use fuel
where a potential source of ignition could occur. (Examples
include: hot water or space heaters, clothes dryer, electric
motors, etc.) Keep flames and sparks away from engine
and fuel to prevent fires. Fuel fires spread very quickly and
are highly explosive.
Prevention of Gasoline Fires
• Never fill your fuel tank with fuel indoors. (Examples
include: basement, garage, barn, shed, house, porch,
etc.)
• Always fill fuel tank outside in a well ventilated area.
• Never remove the fuel cap or add fuel with the engine
running. Stop engine and allow to cool before filling.
• Never drain fuel from engine in an enclosed area.
• Always wipe up excess (spilled) fuel from engine before
starting. Clean up spilled fuel immediately.
• Allow spilled fuel to dry, after wiping and before
starting.
• Allow fuel fumes/vapors to escape from the area before
starting engine.
• Test the fuel cap for proper installation before starting
and using engine.
• Always run the engine with fuel cap properly installed
on the engine.
• Always unscrew gas cap vent screw while engine is
running.
• Never smoke while refilling engine fuel tank.
• Prevent fire and explosion caused by static electric
discharge. Use only nonmetal, portable fuel containers
approved by the Underwriter’s Laboratory (U.L.) or the
American Society for Testing & Materials (ASTM).
• Do not store engine with fuel in fuel tank indoors. Fuel
and fuel vapors are highly explosive.
• During storage, screw down gas cap vent screw
tightly.
• Never pour fuel from engine fuel tank.
• Never siphon fuel by mouth to drain fuel tank.

TRANSPORTING YOUR EDGER
1. Never transport engine inside an enclosed space or
vehicle. Fuel or fuel vapors may ignite causing serious
injury or death.
2. If fuel is present in the fuel tank, transport in an open
vehicle in an upright position.
3. If an enclosed vehicle must be used, remove gas into an
approved red fuel container. DO NOT siphon by mouth.
4. Run engine to use up the fuel in the carburetor and fuel
tank. Always run engine in a well ventilated area.
5. Wipe away any spilled fuel from engine and edger. Allow
to dry.
LONG TERM STORAGE
If your edger will not be used for more than one month,
prepare it for long term storage.
Steps for Long Term Storage
1. Remove the remainder of the fuel from the gas tank into
an approved fuel container.
2. Store edger (engine) in a vertical position.
3. Remove all debris from edger (engine).
