Operating Tips; Maintenance; Replacing The Spool; Replacing The String - Toro 51480 Operator's Manual

Operating Tips

•
Keep the trimmer tilted toward the area being cut; this is the
best cutting area.
•
The string trimmer cuts when passing the unit from left to
right. This avoids throwing debris at the operator.
•
Use the tip of the string to do the cutting; do not force the
string head into uncut grass.
•
Using the trimmer along wire and picket fences, stone and
brick walls, curbs, and wood can cause the line to rapidly
wear and even break.
•
Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by the strings.

Maintenance

After each use of the trimmer, complete the following:
1. Wipe the trimmer clean with a damp cloth. Do not hose the
trimmer down or submerge it in water.
2. Wipe or scrape clean any debris from the cutting-head area.
3. Check and tighten all fasteners. If any part is damaged or
lost, repair or replace it.
4. Brush debris away from the air intake vents on the motor
housing to prevent the motor from overheating.

Replacing the Spool

Note: Use only 1.65 mm (065 in) diameter monofilament string.
For best performance, use only Toro replacement string (part
number 88512).
Important: Using a larger diameter string may cause the
motor to overheat and fail.

3. Remove the spool.
4. Install the new spool, making sure that the strings are
captured in the retaining slots on the new spool.
Note: Make sure that the ends of the strings extend
approximately 152 mm (6 in).
5. Install the new spool so that the string ends align with
the eyelets in the string head, and thread the string ends
through the eyelets.
6. Pull the strings extending from the string head so that the
strings release from the slots in the spool.
7. Install the spool retainer by pressing the tabs into the slots
and pushing down on the spool until the spool retainer clicks
into place.

Replacing the String

Important: Use only .065 inch (1.65 mm) diameter
monofilament string. Do not use any other gauge or type of
string, as this could damage the trimmer.
1. Remove the spool; refer to Replacing the Spool (page 7).
2. Remove any string remaining on the spool.
3. Insert the string into the anchor hole in the upper part of
the spool (Figure 12).
