ADDING OIL: INITIAL USE

Craftsman CMXGTAMDA5SC - ADDING OIL: INITIAL USE - 1

WARNING: OVERFILLING THE CRANKCASE MAY CAUSE SERIOUS PERSONAL INJURY. Check the oil level before each use. The importance of maintaining the proper oil level cannot be overemphasized. Change the oil according to the Maintenance Schedule.

NOTE: This unit was shipped without oil in the crankcase. Oil must be added before starting the unit.

NOTE: This unit comes with a 2.37 fluid oz. (70 ml) container of oil.

  1. Set the unit on a flat, level surface.
  2. Unscrew the oil fill plug (Fig. 14).
  3. Pour the entire container of oil into the oil fill hole (Fig. 14). DO NOT overfill. Refer to Checking the Oil Level.

Oil Fill Plug O-Ring Oil Fill Hole Fig. 14

The use of old fuel is the most common cause of performance problems. Use only fresh, clean unleaded gasoline.

NOTE: This unit has a four-cycle engine. 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, forming acids when stored. ALWAYS use fresh fuel (less than 30 days old).

NOTE: Dispose of old fuel according to federal, state and local regulations.

Using Blended Fuels

If using a blended fuel:

• Always use fresh unleaded gasoline
- Use the fuel additive STA-BIL ^® or an equivalent

Craftsman CMXGTAMDA5SC - Using Blended Fuels - 1

CAUTION: 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.

Using Fuel Additives

Use a fuel additive, such as STA-BIL Fuel Stabilizer or an equivalent, to inhibit corrosion and minimize gum deposits. 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.

FUELING THE UNIT

Craftsman CMXGTAMDA5SC - FUELING THE UNIT - 1

ADJUSTING THE TRIMMING LINE LENGTH (BUMP HEAD)

When used as a bump head, trimming line can be released from the cutting head without stopping the engine. Before doing so, make sure the cutting head is loaded with line. Refer to Replacing the Trimming Line (Bump Head) in the Maintenance section.

To release more line, lightly tap the bump knob on the ground (Fig. 20) while operating the unit at high speed. For best results, tap the bump knob on bare ground or hard soil. Attempting to release line in tall grass may stall the engine.

NOTE: Do not rest the cutting head on the ground while the unit is running.

Each time the bump knob is tapped, about 1.5 inches (38 mm) of trimming line is released.

NOTE: Always keep the trimming line fully extended. Line release becomes more difficult when the cutting line gets shorter.

A blade in the cutting head shield will cut the line to the proper length if any excess line is released.
