MAINTENANCE AND REPAIR INSTRUCTIONS
11
WARNING: Battery tools do not
have to be plugged into an electrical
outlet; therefore, they are always in
operating condition. To prevent
serious personal injury, take extra
precautions and care when
performing maintenance, service or
for changing the cutting attachment
or other attachments.
GENERAL RECOMMENDATIONS
The warranty on this line trimmer does not cover
items that have been subjected to operator
abuse or negligence. To receive full value from
the warranty, the operator must maintain the line
trimmer as instructed in this operator’s manual.
BEFORE EACH USE CHECK FOR
DAMAGED/WORN PARTS
• Bump head — Replace bump head parts
that are bent, warped, cracked, or damaged
in any way.
AFTER EACH USE CLEAN UNIT
AND LABELS
• Clean the unit using a damp cloth with a mild
detergent.
NOTE: Do not use any strong detergents on
the plastic housing or the handle. They
can be damaged by certain household
cleaners that contain aromatic oils
such as pine and lemon, and by
solvents such as kerosene.
• Wipe off the unit with a clean, dry, soft cloth.
• Keep air vents free from debris at all times.
LINE INSTALLATION
Always use genuine replacement line. Using
larger line then the unit is designed for 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 Inner Reel with New Line
To rewind the existing reel you must:
1. Check for the correct line size.
2. Remove the existing reel and spring.
3. Wind the existing reel with the new line.
4. Reinstall the existing reel and spring.
The Correct Line to Use
It is very important to use the correct diameter
size line. This unit uses 2.03 mm (.080 in.)
diameter trimmer line. The motor may overheat
and fail if you use a larger diameter line.
WARNING: Always use genuine
Ryobi replacement line. Do not use
metal-reinforced line.
Removing the Existing Reel and Spring
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. 12).
NOTE: The spring will push the cover up
when the tabs release.
2. Remove the inner reel and spring (Fig. 12).
3. Use a clean cloth to clean the inner surface
of the outer spool (Fig. 12).
NOTE: Always clean the inner reel, outer
spool, and shaft before reassembling
the bump head.
