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 mon-
oxide 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.)
• Never run engine in an enclosed or partially enclosed area.
(Examples include: buildings that are enclosed on one or
more sides, under tents, car ports or basements.)
• Always run the engine with the exhaust and muffler pointed
in the direction away from the operator.
• Never point the exhaust muffler towards anyone. People
should always be many feet away from the operation of the
engine and its attachments.
Gasoline Fires or 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 in-
clude: 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 run-
ning. 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.
• Replace fuel cap that allows gas to spill or leak.
• Never smoke while refilling engine fuel tank.
• Prevent fire and explosion caused by static electric
discharge. Use only non-metal, 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.
• When storing, screw down gas cap vent screw tightly.
• Never pour fuel from engine fuel tank.
• Never siphon fuel by mouth to drain fuel tank.
• Always have an adult fill the fuel tank.
• Never allow an adult or anyone under the influence of
drugs or alcohol to fill engine.
• Never allow children to fill the engine.
BURNS AND FIRES
The muffler, muffler guard and other parts of the engine be-
come extremely hot during the operation of the engine. These
parts remain extremely hot after the engine has stopped.
Prevention of Burns and Fires
• Never remove the muffler guard from the engine.
• Never touch the muffler guard because it is extremely hot
and will cause severe burns.
• Never touch parts of the engine that become hot after
operation.
• Always keep materials and debris away from muffler guard
and other hot parts of the engine to avoid fires.
This engine is designed to operate using a catalytic converter
which contributes to the engine’s compliance with the EPA.
CAUTION
!
HOT GASES ARE A NORMAL BY-PRODUCT OF A
FUNCTIONING CATALYTIC CONVERTER. FOLLOW
ALL SAFETY INSTRUCTIONSTO PREVENT BURNS
AND FIRES.

5. Check all parts that were repaired, or removed during repair,
that they are secure and fit correctly.
NOTE: All repair parts must come from the factory. Never
replace parts that are not specifically designed for the
power drill.
6. Replace spark plug wire.
PREPARING ENGINE FOR STARTING
GAS AND OIL
Quality
To operate the engine, we recommend using “VIPER” brand 2-
cycle oil (PN 300400) to ensure that the engine operates correctly
throughout the life of the engine. Use unleaded regular gas only.
Mixture
Run engine with a 50:1 ratio.
MIXING FUEL AND FILLING GAS TANK
Mixing Fuel
1. Fuel must be mixed in a container outside in a well ventilated
area.
2. Fill certified fuel container 1/4 full of recommended fuel.
3. Add recommended amount of 2 cycle oil.
4. Screw container cap on straight and tight.
5. Shake the container to mix fuel and oil.
6. Unscrew gas cap slowly to vent, add the remainder of fuel re-
quirements.
7. Wipe away any spilled fuel or oil and allow to evaporate before
moving or transporting.
