FILLING FUEL TANK
Add fuel to fuel tank as needed. See your
Engine Manual for correct type and grade of
fuel.
To add fuel to the fuel tank:
1. Clean fuel caps and surrounding area to
prevent dust, dirt, and debris from entering
fuel tanks.
2. Remove fuel caps.
IMPORTANT: Refer to Engine Manual for
correct type and grade of fuel.
3. Fill fuel tank to the bottom of filler neck.
See SPECIFICATIONS on page 19 for fuel
tank capacity.
IMPORTANT: DO NOT OVERFILL! This
equipment and/or its engine may include
evaporative emissions control system
components, required to meet EPA and/or
CARB regulations, that will only function
properly when the fuel tank has been filled to
the recommended level. Overfilling may cause
permanent damage to evaporative emissions
control system components. Filling to the
recommended level ensures a vapor gap
required to allow for fuel expansion. Pay close
attention while filling the fuel tank to ensure
that the recommended fuel level inside the
tank is not exceeded. Use a portable gasoline
container with an appropriately sized
dispensing spout when filling the tank. Do not
use a funnel or other device that obstructs the
view of the tank filling process.
4. Replace fuel cap and tighten.
5. ALWAYS clean up spilled fuel.
GASOLINE
IMPORTANT: ALWAYS use gasoline that
meets the following guidelines:
• Clean, fresh gasoline.
• A minimum of 87 octane/87 AKI (91 RON).
High altitude use may require a different
octane. Consult your engine manual.
• Gasoline with up to 10% ethanol (gasohol)
or up to 10% MTBE (methyl tertiary butyl
ether) is acceptable.
OPERATION
WARNING: AVOID INJURY. Read
and understand the entire Safety
section before proceeding.
Fast Slow Stop
WARNING: AVOID INJURY. Read
and understand entire Safety
section before proceeding.

EN - 11
• Use of any gasoline other than those
approved above will void the engine
warranty. If the pumps are not marked for
the content of alcohol or ethers, check
ethanol and MTBE levels with the fuel
supplier.
• Do not modify the fuel system to use
different fuels.
• Never mix oil and gasoline.
NOTE: All gasoline is not the same. If the
engine experiences starting or performance
problems after using a new gasoline, switch to
a different fuel provider or fuel brand.
IMPORTANT: Excessively oxygenated or
reformulated fuels (fuels blended with alcohols
or ethers) can damage the fuel system or
cause performance problems. If any
undesirable operating problems occur, use a
gasoline with a lower percentage of alcohol or
ether.
Fuel Stabilizer
Gasoline left in the fuel system for extended
periods without a stabilizer will deteriorate,
resulting in gum deposits in the system. These
deposits can damage the carburetor and the
fuel hoses, filter and tank. Prevent deposits
from forming in the fuel system during storage
by adding a quality fuel stabilizer to the fuel.
Follow the recommended mix ratio found on
the fuel stabilizer container.
TO STOP IN AN EMERGENCY

If the trimmer is to be stored for more than 30
days, follow these steps to prepare your unit.
1. Run the engine until it stops from running
out of gasoline. See Engine Manual for
specific instructions on preparing the
engine for storage.
2. Clean all dirt and debris from the trimmer.
See MAINTENANCE on page 12 for
cleaning instructions.
3. Inspect unit for signs of wear, breakage or
damage. Order any parts required and
make necessary repairs to avoid delays
when beginning use again.
4. Keep all nuts, bolts and screws properly
tightened and know unit is in safe working
condition.
Fuel System
Gasoline left in the fuel system for extended
periods without a stabilizer will deteriorate,
resulting in gum deposits in the system. These
deposits can damage the carburetor and the
fuel hoses, filter and tank. Prevent deposits
from forming in the fuel system during storage
by adding a quality fuel stabilizer to the fuel.
Follow the recommended mix ratio found on
the fuel stabilizer container.
To treat the fuel system for storage:
1. Add fuel stabilizer according to
manufacturer’s instructions.
2. Run engine for at least 10 minutes after
adding stabilizer to allow it to reach the
carburetor.
NEVER store the engine with fuel in the fuel
tank inside of a building with potential sources
of ignition.

WARNING: AVOID INJURY. Read
and understand the entire Safety
section before proceeding.
