instructionscarefullyfortheproperfuel/oilmixture.
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 you choose to use a blended fuel, or its use is unavoidable, follow
recommended precautions:
• Always use the fresh fuel mix explained in your operator's manual
• Always agitate the fuel mix before fueling the unit
• Drain the tank and run the engine dry before storing the unit
Using Fuel Additives
The bottle of 2-cycle oil that came with your unit contains a fuel
additive which will help inhibit corrosion and minimize the formation of
gum deposits. It is recommended that you use our 2-cycle oil with this
unit. If unavailable, use a good 2-cycle oil de-signed 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.
reliability, pay strict attention to the oil and fuel mixing
I_ _CAUTION: For proper engine operation and maximum
Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded
gasoline 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 below for
specific gas and oil mixing
ratios.

3. Reinstall line glide plate
(Fig. 10). The glide plate is
a keyed item and will only Fig. 12
fit one way. If it does not go into the cutting head smoothly, DO
NOT force it. Rotate the glide plate until it slides into the cutting
head easily.
NOTE: The glide plate must be installed in the cutting head before
inserting new line.
4. Insert both ends of your line through the large holes in the side
of the cutting head (Fig. 11).
5. Push and/or pull the line so that the line issnug against the hub and
is fullyextended through the positioning tunnels. (Fig. 12)
6. Correctly installed line will be the same length on both sides.
NOTE: Make sure that when installing new line,that the line is as close
to even as possible. Any variation in lengths may cause the unit
to vibrate excessively. If this happens, stop the unit and make
sure the line is even.
7. Repeat steps 4 thru 6 to install the second trimmer line.
NOTE: Do not rest the Hassle-Free TM PLUS Cutting Head on the
ground while the unit is running.
Some line breakage will occur from:
• Entanglement with foreign matter
Normal line fatigue
Attempting to cut thick, stalky weeds
Forcing the line into objects such as walls or fence posts
NOTE: During normal use the trimming line may become worn
unevenly which may cause excessive vibrations in the unit.
If this becomes uncomfortable or uncontrollable, stop the
unit and replace the line. Referto the Line Replacement
instructions above.
