Maintenance - Craftsman WS225 Operator's Manual

WARNING:
To avoid serious personal injury, always stop
the engine and allow it to cool before cleaning or maintaining
the unit. Never perform cleaning or maintenance while the
unit is running. Disconnect the spark plug wire to prevent
the unit from starting accidentally.
WARNING:
Wear protective clothing and observe all
safety instructions to prevent serious personal injury.
REPLACING THE TRIMMING LINE
Only use the trimming line described in the Specifications section.
Other types of trimming line may cause the unit to overheat or fail.
WARNING:
Never use metal-reinforced line, wire, chain or
rope. These can break off and become dangerous projectiles.
NOTE: Always use the correct line length when installing trimming
line. The line may not release properly if the line is too long.
NOTE: The cutting head will remain attached to the unit.
NOTE: DO NOT disassemble the cutting head to install new line.
Installing New Trimming Line
1. If necessary, remove any old trimming line and/or obstructions
from the cutting head. Refer to Removing Old Trimming Line and
Obstructions.
2. Cut two 10-foot (3.0 m) lengths of new trimming line. Cut one
end of each line at a 30 degree angle (Fig. 16).
3. Turn the bump knob to align the arrows on the bump knob with
the arrows on the spool cover (Fig. 15).
4. Insert one of the lines into an eyelet on the cutting head (Fig. 16).
Use the angled end and push the line in about 3 inches (7.5 cm).
Repeat this process with the other line and remaining eyelet.
5. Turn the bump knob to wind the line until about 5 inches (12.5 cm)
protrude from each side of the cutting head (Fig. 17).
NOTE: DO NOT push the bump knob down while winding the line.
The bump knob will only turn one way, depending upon the unit
model.
NOTE: If too little line is left protruding, it could retract inside the
cutting head.
