WARNING: OVERFILLING THE 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.
RECOMMENDED OIL TYPE
Using the proper type and weight of oil in the crankcase is extremely important.
Check the oil before each use and change the oil regularly. Failure to use the
correct oil, or using dirty oil, can cause premature engine wear and failure.
Use a high-quality SAE 30 weight oil of API (American Petroleum Institute)
service class SF, SG, SH.

RECOMMENDED FUEL TYPE
Old fuel is the primary reason for improper \
unit performance. Be sure to use fresh,
clean, unleaded gasoline. Dispose of the
old gasoline in accordance to federal, '_
state and local regulations.
NOTE: This is a four cycle engine. In
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 form acids when stored. Use fresh fuel (less than
60 days old), when using alcohol-blended fuel.
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable, follow
recommended precautions:
• Always use fresh unleaded gasoline
• Use a gas stabilizer fuel additive
• Drain tank and run the engine dry before storing unit
Using Fuel Additives
The use of a gas stabilizer 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 fuel
additive container. NEVER add fuel additives directly to the unit's gas tank.

WARNING: Always wear eye, hearing, foot and body protection
I _hb I to reduce the risk of injury when operating this unit.
HOLDING THE TRIMMER
Before operating the unit, stand in the operating
position (Fig. 9). Check for the following:
• The operator is wearing eye protection and
proper clothing
• With a slightly-bent right arm, the operator's
right hand is holding the shaft grip
• The operator's left arm is straight, the left hand
holding the handle
• The unit is at waist level
• The cutting attachment is parallel to the ground
and easily contacts the grass without the need
to bend over
BUMP KNOB LINE ADVANCE
Tap the bump knob on the ground to advance the -- Fig. 9
cutting line when necessary.
TIPS FOR BEST TRIMMING RESULTS
• For best trimming results, operate unit with throttle control fully squeezed.
• Keep the cutting attachment parallel to the ground.
• Do not force the cutting attachment. Allow the tip of the line to do the
cutting, especially along wails. Cutting with more than the tip will reduce
cutting efficiency and may overload the engine.
• Cut grass over 8 inches (200 ram) by working from top to bottom in small
increments to avoid premature line wear or engine drag.
• Cut from right to left.
• Slowly move the trimmer into and out of the cutting area at the desired
height. Move either in a forward-backward or side-to-side motion. Cutting
shorter lengths produces the best results.
• Trim only when grass and weeds are dry.
• The life of your cutting line is dependent upon:
- Proper adherence of explained trimming techniques
- What vegetation is cut
- Where vegetation is cut
For example, the line will wear faster when trimming against a foundation
wall as opposed to trimming around a tree. It is normal for some line
breakage to occur from regular use.
Decorative trimming is accomplished by removing all vegetation around

trees, posts, fences and more.
Rotate the whole unit so that the cutting attachment is at a 30 ° angle to the
ground (Fig. 10).

Always use Craftsman XTRA QUIET TM0.095 inch (2.413 mm) original
equipment manufacturer replacement line. Lines other than the specified
may make the engine overheat or fail.
There are two methods to replace the Rapid Rewind zu trimming line:
• Wind the inner reel with new line
• Install a pre-wound inner reel
Winding the Inner Reel With New Line
NOTE: It Is unnecessary to remove the bump knob to install a new
trimming line.
1. Cut two 7 ft (2.1 m) pieces of 0.095-inch (2.413 mm) trimming line.
NOTE: Always use the correct line length when installing trimming line on
the unit. The line may not release properly if the line is too long.
2. Hold the outer spool and turn the inner reel counterclockwise to line up
the arrows on the outer spool and inner reel (Fig. 11).

4.
Making sure arrows are aligned, insert the end of a piece of trimming
line straight into one of the two eyelets in the outer spool. Push it up
through the line loading hole in the inner reel (Fig. 12). Do not bend the
line when inserting it into the eyelet.
5.
Insert the line into the locking hole (Fig. 13). Do not push the line more
than a 1/2 inch (12.7 mm) into the line locking hole. The line will form a
small loop (Fig. 13) when it is inserted correctly.
6.
Pull the line from the outer spool until the line is tight against the inner
reel (Fig. 14).
7.
Repeat procedures 4-6 with the second piece of line in the other eyelet.
NOTE:
Do not wind the inner reel before installing the second piece of line.
Fig. 15
9. If winding the line becomes difficult or if the line jams, pull the ends of
the line from the spool (Fig. 16). Continue winding the inner reel
counterclockwise until 4 inches of line remains on each side.
Fig. 16
CLEANING THE RAPID REWIND TM HEAD
NOTE: Also perform these steps when replacing inner reel with a new
prewound reel.
Cleaning the Rapid Rewind TM may be necessary if:
• A jammed or excessive line must be removed
• The Rapid Rewind TM becomes difficult to wind or does not operate
correctly when bumping the head on the ground.
1. Hold the outer spool, and unscrew the bump knob counterclockwise
(Fig. 17).
3.
Pull the inner reel with existing line from the outer spool.
4.
If rewinding with new line, remove any existing line from the inner reel
before cleaning. Remove any debris or grass from the knob, spring, inner
reel and foam seal. Wash the inner reel with warm soapy water (Fig. 19).
