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.

REPLACING THE SPOOL (BUMP HEAD)
1. Push in the tabs on the side of the spool retainer and
pull to remove (Fig. 14).
2. Install the spring, washer, and rewound spool,
making sure that the lines are captured in the holding
slots on the new spool.
NOTE: Make sure that the ends of the lines extend
approximately 6 in. (152 mm).
3. Install the new spool so that the line ends align with
the eyelets in the cutting head, and thread the line
ends through the eyelets.
4. Pull the lines extending from the cutting head so that
the strings release from the slots in the spool.
5. Install the spool retainer by pressing the tabs into the
slots and pushing down on the spool until the spool
retainer clicks into place (Fig. 14).
REPLACING THE TRIMMING LINE
(BUMP HEAD)
1. Remove the spool from the cutting head.

cloth to clean the surface of the cutting head.
3. Cut a 15 ft. (4.5 m) length of 0.095 in. (2.4 mm)
diameter trimming line.
4. Bend the line at the midpoint and insert the bend into
the holding slot on the spool (Fig. 15).
5. Wrap the line evenly and firmly around the spool
(Fig. 16).
