MAINTENANCE AND REPAIR INSTRUCTIONS
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.”
LINE INSTALLATION
Always use genuine original equipment manufacturer
0.080 in. (2.03 mm.) replacement line. Using line other
than specified may cause the unit to overheat or fail.
There are two methods to replace the trimmer line:
•Wind the inner reel with new line
• Install a prewound inner reel
Winding the Existing Reel
1. Remove the bump head cover by pressing in both
bump head cover tabs visible on either side of the
bump head outer spool (Fig. 11).
NOTE: The spring will push the cover up when the tabs
release.
2. Remove the inner reel and spring (Fig. 11).
3. Use a clean cloth to wipe the inner surface of the
outer spool (Fig. 11).
The warranty on this unit does not cover items that have
been subjected to operator abuse or negligence. To
receive full value from the warranty, the operator must
