FUEL AND REFUELING
HANDLING THE FUEL SAFELY
■ ■ ■ ■ ■ Always handle fuel with care, it is highly flammable.
■ ■ ■ ■ ■ Always refuel outdoors where there are no sparks and
flames. Do not inhale fuel vapors.
■ ■ ■ ■ ■ Do not let gasoline or oil come in contact with your skin.
■ ■ ■ ■ ■ Keep gasoline and oil away from the eyes. If gasoline or
oil comes in contact with the eyes, wash them immedi-
ately with clean water. If irritation is still present, see a
doctor immediately.
■ ■ ■ ■ ■ Clean up spilled fuel immediately.
MIXING THE FUEL
■ ■ ■ ■ ■ This product is powered by a 2-cycle engine and requires
pre-mixing gasoline and 2-cycle oil. Pre-mix unleaded
gasoline and 2-cycle engine oil in a clean container
approved for gasoline.
■ ■ ■ ■ ■ This engine is certified to operate on unleaded gasoline
intended for automotive use with an octane rating of 87
([R + M] / 2) or higher.
■ ■ ■ ■ ■ Do not use any type of pre-mixed gasoline/oil from fuel
service stations, this includes the pre-mixed gasoline/oil
intended for use in mopeds, motorcycles, etc.
■ ■ ■ ■ ■ Use high a quality 2-cycle self mixing oil for air cooled
engines. Do not use automotive oil or 2-cycle outboard
oil.
■ ■ ■ ■ ■ Mix 2% oil into the gasoline. This is a 50:1 ratio.
■ ■ ■ ■ ■ Mix the fuel thoroughly and also each time before
fueling.
■ ■ ■ ■ ■ Mix in small quantities. Do not mix quantities larger than
usable in a 30 day period. A 2-cycle oil containing a fuel
stabilizer is recommended.
FILLING THE TANK
1. Clean surface around fuel cap to prevent contamination.
2. Loosen fuel cap slowly to release pressure and to keep
fuel from escaping around the cap.
3. Carefully pour fuel mixture into the tank. Avoid spillage.
4. Prior to replacing the fuel cap, clean and inspect the
gasket.
5. Immediately replace fuel cap and hand tighten. Wipe up
any fuel spillage. Move 9 m (30 ft.) away from refueling
site before starting engine.
NOTE: It is normal for smoke to be emitted from a new
engine during and after first use.

WARNING
Always shut off engine before fueling. Never add fuel
to a machine with a running or hot engine. Move at
least 9 m (30 ft.) from refueling site before starting
engine. Do not smoke!
OPERATION
OPERATING THE TRIMMER
Hold the trimmer/brushcutter with the right hand on the rear
handle and the left hand on the front handle. Keep a firm
grip with both hands while in operation. Trimmer should be
held at a comfortable position with the rear handle about hip
height. See
Figure 11.
Always operate trimmer at full throttle. Cut tall grass from
the top down. This will prevent grass from wrapping around
the shaft housing and string head which may cause damage
from overheating. If grass becomes wrapped around the
string head, stop the engine, disconnect the spark plug
wire, and remove the grass. Prolonged cutting at partial
throttle will result in oil dripping from the muffler.
