CUTTING LINE (Figs. 2 & 3)
NOTE: The cutting line for your trim-
mer is a special monofilament line.
Your trimmer comes complete with a
12 foot supply of this line already
wound onto the spool.
1. To avoid tangling line during ship-
ment, the tip of the monofilament line
has been taped to the head assembly.
The tape must be removed before op-
eration (Fig. 2).

loop the line through the eyelet to pre-
vent unraveling (Fig. 3).

switch bar. The trimmer will stop sec-
onds after switch is released.
Do not invert trimmer until cutting
head has completely stopped ro-
tating and trimmer has been un-
plugged from PowerPack.
TIPS FOR BEST TRIMMING RESULTS
Your trimmer will cut grass and small
weeds in difficult and hard to reach
places. However, you will experience
some line breakages during your first
few uses. As you learn the trimming
techniques, you will be able to cut ar-
eas around trees, shrubs, foundation
walls, along fences, sidewalks, patios,
4
etc., With minimal line wear or break-
age.
1. Hold the cutting head parallel to the
ground, and the cutting head will be at
the correct angle with the grass to be
trimmed.
2. DO NOT FORCE THE UNIT. Allow
the very tip of the nylon line to do the
cutting (especially along walls)
(Fig. 6). Cutting with more than the tip
will reduce cutting efficiency and over-
load the motor.
Figure 6
The tip of the cutting line will wear dur-
ing use and cause a reduction in the
cutting swath. If the line is not ad-
vanced occasionally, it will wear down
to the drum eyelet. When the trimmer
is stopped, the line tends to relax and
may retract into the drum. Should this
occur, unplug the PowerPack and be
sure to replace the cutting line in the
proper position before restarting the
trimmer or the line may tangle around
the drum.
3. Grass over 8 inches tall should be
cut by working from the top to the bot-
tom in small increments to avoid pre-
mature line wear or motor drag.
4. Whenever possible, cut to your left.
When cutting to the left, the unit's cut-
ting efficiency is somewhat better since
the line is contacting the grass as soon
as it leaves the guard, and the clip-
pings are moving away from the opera-
tor.
5. Slowly move the trimmer into and
out of the area being cut, maintaining
trimmer at desired cutting height. This
can be either a forward-backward or
side-to-side motion (Figs. 7 & 8).
Maintain top speed for best cutting.

Figure 8
Side-to-side cutting motion
6. Trim only when grass and weeds
are dry.
7. The life of your cutting line is de-
pendent upon following the previously
stated trimming techniques, as well as
what is being cut, and where the cut-
ting is being done. For example, line
will wear faster when trimming against
a foundation wall as opposed to trim-
ming around a tree. Some line break-
age will occur from moving unit too
fast, from entanglement with foreign
matter, from normal line fatigue, and
from attempting to cut thick, stalky
weeds in excess of unit's capability. As
cutting line wears, for best perform-
ance, lengthen as indicated in Length-
ening Cutting Line procedure.
8. Never drag the trimmer spool cap
on the ground while trimming. This
causes unnecessary battery drain and
spool cap wear (Fig. 9).
Figure 9
LENGTHENING CUTTING LINE
(Fig. 10)
1. To lengthen line, firmly tap spool on
the ground while the motor continues
to run. The line will be fed from the
spool and cut off to the proper length
by the cutting knife attached to the
shield.
Remember to keep the trimmer running
while lengthening the line. Just tap the
trimmer on the ground; do not hold it
on the ground. After the tap and the
line has fed out, wait until you hear the
line being cut to the proper length be-
fore continuing to trim.
Figure 10
OPERATING INSTRUCTIONS
Note: To help prevent line tangle, tap
once only to lengthen line. If additional
line is required, wait a few seconds
before retapping trimmer head. Do not
allow line to wear too short. Keep line
length at 9" diameter as much as pos-
sible.
2. Lengthen the line only when line has
been shortened by wear. Unnecessary
lengthening will waste line.
Note: The spool cap may wear during
normal use of the line advance feature
and may require occasional replace-
ment. Replacements are available
through your local Toro retailer.
For optimum performance, use
only TORO .050” nylon monofila-
ment cutting line. The trimmer
will not perform the way it is de-
signed to if another weight of cut-
ting line is used.
REPLACING CUTTING LINE
Replacement line or prewound replace-
ment spools can be purchased from
your local Toro retailer. The cutting line
used by TORO is specially formulated
for use on your trimmer. Other line
may not provide the same high quality
performance.
Always be sure cutting head has
completely stopped rotating and
trimmer is unplugged from Power-
Pack™ before inverting it.
1. To remove empty spool, insert wid-
est possible blade screwdriver snugly
into one of the two window slots on the
spool hub and twist screwdriver 1/4
turn (Fig. 11). Spool will snap off.

Figure 11
2. To rewind empty spool, follow these
steps:
A. Hook one end of line into groove on
spool, allowing no more than 1/8”
to protrude. Wind line in direction of
arrows on spool in level rows be-
tween spool flanges as shown in
Figure 12.
Note: Trimmer will not function
properly if line is wound in the
wrong direction.
B. Do not wind more than 12 feet of
line onto spool. Do not use line over
.050” diameter.
1/8" Max WIND LINE

C. Keep line tight on spool by making a
hook in the line and secure in
groove (Fig. 13).

OPERATING INSTRUCTIONS
Note: Before reassembly, be sure
to thoroughly clean out drum area
and visually inspect for any dam-
aged or worn parts.
D. The spool and the core are keyed.
Be sure they are properly aligned
when putting spool back on
(Fig. 14). Thread end of line
through eyelet, place spool on
keyed core, and push in place until
you hear it click (Figs. 14 & 15).
Pull line free from groove in spool.
Unwind no more than 3 inches from
spool.
3. If line should tangle or break at eye-
let, refeed cutting line through eyelet
by pushing spool in as far as it will go
and threading line back through eyelet.
Or you may remove spool completely,
refeed the line through the eyelet, and
reassemble spool to trimmer.
Figure 15
GENERAL MAINTENANCE
Always be sure your trimmer is
stopped and unplugged from Pow-
erPack™ before attempting any
maintenance.
1. To keep the exterior clean, just wipe
it off with a damp cloth—never hose it
down.
2. Wipe or scrape clean the drum and
spool area anytime there is an accu-
mulation of dirt or cuttings.
3. Check and tighten all fasteners. If
any part is damaged, repair or replace
it.
4. Air exhaust vent is located on un-
derside of shield (Fig. 16). Scrape
vent clean regularly.
5. Wipe debris from air intake holes in
motor housing (Fig. 16).
IMPORTANT: Keeping intake and ex-
haust vents free of grass and debris
prevents motor overheating and possi-
ble failure.
