MAINTENANCE AND REPAIR INSTRUCTIONS
LINE INSTALLATION
This section covers both SplitLine™ and standard single
line installation.
Always use original equipment manufacturer 0.065 in.
(1.65 mm) replacement line. Line other than the specified
may make the motor overheat or fail.
There are two methods to replace the trimming line:
• Wind the inner reel with new line
• Install a prewound inner reel
Winding the Existing Inner Reel
1. Hold the outer spool with one hand and unscrew the
Bump Knob™ counterclockwise (Fig. 11). Inspect the
bolt inside the Bump Knob to make sure it moves
freely. Replace the Bump Knob if damaged.
2. Remove the inner reel from the outer spool (Fig. 12).
3. Remove spring from the inner reel (Fig. 12).
4. Use a clean cloth to clean the the inner reel, spring,
shaft, and inner surface of the outer spool.
5. Check the indexing teeth on the inner reel and outer
spool for wear (Fig. 13). If necessary, remove burrs or
replace the reel and spool.

either type of inner reel. Use Figure 14 to identify
the inner reel you have.

SERVICING DOUBLE INSULATED UNITS
This unit is double-insulated. In a double-insulated unit,
two systems of insulation are provided instead of
grounding. There is no grounding provided and no
means of grounding should be added to this unit.
Extreme care and knowledge of the system is required
when servicing a double-insulated unit. Service should
be performed by qualified service personnel only.
Replacement parts for a double-insulated unit must be
identical to the parts they replace. Refer any repair to an
authorized service dealer. A double-insulated unit is
marked with the words “double insulation” or “double
insulated.”
