Troy-Bilt 2-Cycle Trimmer TB2040 XP - Manual (Page 3)

STARTING INSTRUCTIONS
1. Mix fuel with oil. Fill fuel tank with fuel/oil mixture. See Oil and Fuel
Mixing Instructions.
2. Fill the fuel tank with fresh, clean unleaded fuel. Refer to Fueling the
Unit.
NOTE: There is no need to turn the unit on. The On/Off Control is in the
ON ( I ) position at all times (Fig. 6).
3. Fully press and release the primer bulb 10 times, slowly. Some amount
of fuel should be visible in the primer bulb and fuel lines (Fig. 7). If fuel
can not be seen in the bulb, press and release the bulb until fuel is
visible.
4. Place the choke lever in Position 1 (Fig. 7).
5. Crouch in the starting position (Fig. 8). Squeeze the throttle control
lever. Pull the starter rope 5 times.
6. Place the choke lever in Position 2 (Fig. 7)
7. Squeeze the throttle control, pull the starter rope in a controlled motion
3 to 5 times to start engine.
8. Keep the throttle squeezed and allow the engine to warm up for 30 to
60 seconds.
9. Continue squeezing the throttle control, move the choke lever to Position 3 (Fig. 7) and continue
warming the engine for an additional 60 seconds. The unit may be used during this time.
NOTE: Unit is properly warmed up when engine accelerates without hesitation.
IF... the engine hesitates, return the choke lever to Position 2 (Fig. 7) and continue warm-up.
IF... the engine does not start, go back to step 3.
IF... the engine fails to start after 2 attempts, place the choke lever in Position 3 and squeeze the
throttle control. Pull the starter rope out with a controlled and steady motion 3 to 8 times. The engine
should start. If not, repeat.
IF WARM... If the engine is already warm, go back to step 6.
STOPPING INSTRUCTIONS
1. Release the throttle control and allow the engine to cool down by idling.
2. Press and hold the On/Off Control switch in the OFF (O) position until the unit comes to a complete
stop (Fig. 6).
The bottle of 2-cycle oil contains a fuel additive which will help inhibit
corrosion and minimize the formation of gum deposits. It is
recommended to use our 2-cycle oil with this unit.
If unavailable, use a good 2-cycle oil designed for air-cooled engines
along with a fuel additive, such as STA-BIL® Gas Stabilizer or an
equivalent. Add 0.8 oz. (23 ml.) of fuel additive per gallon of fuel
according to the instructions on the container. NEVER add fuel additives directly to the unit's fuel tank.
Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded fuel in a separate fuel can. Use a
40:1 fuel/oil ratio. Do not mix them directly in the engine fuel tank. See the table for specific gas and oil
mixing ratios.
NOTE: One gallon (3.8 liters) of unleaded fuel mixed with one 3.2 oz. (95 ml.) bottle of 2-cycle oil makes a 40:1
fuel/oil ratio.
NOTE: Dispose of the old fuel/oil mix in accordance to federal, state and local regulations.
FUELING THE UNIT
1. Turn unit on its side, with the fuel cap facing up, and remove the fuel cap.
2. Place the gas container’s spout into the fill hole on the fuel tank and fill the tank.
NOTE: Do not overfill the tank.
3. Wipe up any gasoline that may have spilled.
4. Reinstall the fuel cap.
5. Move the unit at least 30 ft. (9.1 m) from the fueling source and site before starting the engine.
OIL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main reasons for the unit not running properly. Be sure to use
fresh, clean unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture.
DEFINITION OF BLENDED FUELS
Today's fuels are often a blend of gasoline and oxygenates such as ethanol, methanol, or MTBE (ether).
Alcohol-blended fuel absorbs water. As little as 1% water in the fuel can make fuel and oil separate. It
forms acids when stored. When using alcohol-blended fuel, use fresh fuel (less than 60 days old).
USING BLENDED FUELS
If choosing to use a blended fuel, or its use is unavoidable, follow recommended precautions:
• Always use the fresh fuel mix explained in the operator's manual
• Always agitate the fuel mix before fueling the unit
• Drain the tank and run the engine dry before storing the unit

CAUTION: For proper engine operation and maximum reliability, pay strict attention to the oil and fuel
mixing instructions on the 2-cycle oil container. Using improperly mixed fuel can severely damage the engine.
WARNING: Gasoline is extremely flammable. Ignited vapors
may explode. Always stop the engine and allow it to cool
before filling the fuel tank. Do not smoke while filling the tank.
Keep sparks and open flames at a distance from the area.
WARNING: Remove fuel cap slowly to avoid injury from fuel spray. Never operate the unit without the
fuel cap securely in place.
WARNING: Add fuel in a clean, level and well ventilated outdoor area. Wipe up any spilled fuel immediately.
Avoid creating a source of ignition for spilled fuel. Do not start the engine until fuel vapors dissipate.
STARTING/STOPPING INSTRUCTIONS
WARNING: Avoid accidental starting. Make sure you are in the
starting position when pulling the starter rope (Fig. 8). To avoid serious
injury, the operator and unit must be in a stable position while starting.
