Maintenance

After each use of the trimmer, complete the following:
1. Remove the battery from the trimmer.
2. Wipe the trimmer clean with a damp cloth. Do not hose the
trimmer down or submerge it in water.
CAUTION
The line cut-off blade on the deflector is sharp and
can cut you. Do not use your hands to clean the
deflector shield and blade.
3. Wipe or scrape clean the cutting head area any time there is
an accumulation of debris.
4. Check and tighten all fasteners. If any part is damaged or
lost, repair or replace it.
5. Brush debris away from air intake vents on motor housing
to prevent the motor from overheating.

Replacing the Spool

Use only .065 inch (1.6 mm) diameter monofilament string. Use
original manufacturer's replacement string for best performance
(Toro part number 88532 or 88524).
Important: Use of a larger diameter string will cause the
motor to overheat and fail.
1. Remove the battery.
2. Push in the tabs on the side of the spool retainer (Figure 19).

3. Pull the spool retainer up to remove it and remove the spool.
4. To install the new spool, make sure the string is captured in
one of the retaining slots on the new spool. Make sure the
end of the string extends approximately 6 inches (152 mm).
5. Install the new spool so that the string aligns with the eyelet
in the string head. Thread the string into the eyelet.
6. Pull the string extending from the string head so the string
releases from the slot in the spool.
7. Reinstall the spool retainer by depressing tabs into slots and
pushing down until spool retainer clicks into place.
