Maintenance - Craftsman 316.725860 Operator's Manual

WARNING:
To prevent serious injury, never perform
maintenance or repairs while the unit is running. Always
allow the unit to cool before servicing or repairing the unit.
Prevent the unit from starting accidentally. For gas-
powered units, disconnect the spark plug wire. For battery-
powered units, remove the battery. For corded electric
units, disconnect the unit from the power source.
REPLACING THE TRIMMING LINE
Only use the trimming line described in the Specifications section.
Other types of trimming line may cause the engine to overheat or fail.
WARNING:
Never use metal-reinforced line, wire, chain or
rope. These can break off and become dangerous projectiles.
Installing New Trimming Line
1. Remove the old line from the cutting head.
2. Use a clean cloth to clean the surface of the cutting head. If the
cutting head is too dirty to accept new line, refer to Cleaning the
Cutting Head.
3. Insert the ends of the line through the large circular holes in the
side of the cutting head (Fig. 7). Push the line through the holes
until both ends protrude from the positioning tunnels (Fig. 8).
4. Pull the ends of the line until the line is tight against the cutting
head. Make sure the ends of the line are of equal length (Fig. 9).
Cleaning the Cutting Head
NOTE: The cutting head will remain attached to the unit.
1. Remove the old line from the cutting head. The line glide plate
cannot be removed if there is still line in the cutting head.
2. Insert a small Phillips screwdriver into the locking tab hole and push
the locking tab inward (Fig. 10). At the same time, pull the line glide
plate out of the cutting head.
3. Use a clean cloth to clean the insides of the cutting head and
line glide plate.
4. Align the arrow on the line glide plate with the arrow on the
cutting head (Fig. 10).
5. Push the line glide plate into the cutting head until the locking
tab snaps into place.
