OPERATING THE COUPLER
WARNING:
Before using any attachment, read and understand the manual that came
with the attachment. Follow all safety information contained within.
WARNING:
To avoid serious personal injury and damage to the unit, shut the unit off
before removing or installing an attachment.
The coupler enables the use of various optional attachments.
NOTE: To make installing or removing the attachment easier, place the
unit on the ground or on a work bench.
Installing the Attachment
NOTE: Remove the protective cap and gray spacer from the upper and
lower shafts prior to assembling the attachment.
1. Turn the knob counterclockwise to loosen (Fig. 13).
2. While firmly holding the attachment, push it straight into the coupler
until the release button snaps firmly into the primary hole (Fig. 15).
NOTE: Aligning the release button with the guide recess will help
installation (Fig. 14).
3. Turn the knob clockwise to tighten (Fig. 13).
NOTE: Do not tighten the nut (Fig. 14).
CAUTION:
Before operating the unit, make sure the release
button is fully snapped into the primary hole (Fig. 15) and the
knob (Fig. 13) is securely tightened.
CAUTION:
The release button should be snapped into the
primary hole only. Using the wrong hole could lead to personal
injury or damage to the unit.
For decorative edging with a string trimmer attachment, lock the release
button into the 90° edging hole (Fig. 13).
Removing the Attachment
1. Turn the knob counterclockwise to loosen (Fig. 13).
2. Press and hold the release button (Fig. 14).

RECOMMENDED FUEL TYPE
Old fuel is the primary reason for improper unit performance. Be sure to
Cutting Attachment
use fresh, clean, unleaded gasoline.
NOTE: This is a four cycle engine. In order to avoid damage to the unit, do
not mix oil with gasoline.
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 or form acids

USING FUEL ADDITIVES
Pilot
Step
Fig. 9
The use of fuel additives, such as STA-BIL® Gas Stabilizer or an equivalent, will inhibit corrosion and
minimize the formation of gum deposits. Using a fuel additive can keep fuel from forming harmful
deposits in the carburetor for up to six (6) months. 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 gas tank.
FUELING THE UNIT

OIL AND FUEL INFORMATION

WARNING:
Overfilling oil crankcase may cause serious personal injury. Check and
maintain the proper oil level in the crank case; it is important and cannot be overemphasized.
Check the oil before each use and change it as needed. See Changing the Oil.
WARNING:
Add fuel in a clean, well ventilated outdoor area. Wipe up any spilled fuel
immediately. Avoid creating a source of ignition for spilt fuel. Do not start the engine until
fuel vapors dissipate.
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:
DO NOT USE E85 FUEL IN THIS UNIT. It has been proven that fuel
containing greater than 10% ethanol will likely damage this engine and void the warranty.
