IMPORTANT WARNINGS FOR STRING
TRIMMERS
1. Use the proper size and type of cutting line. Do not use metal
wire, rope or the like. Do not use cutting line heavier than that
recommended by the manufacturer. See the accessory section of
this manual for more detailed information about the proper
cutting line to use.
2. Keep the cutting line trimmed to the proper length (done
automatically by the appliance). Make sure that the guard is
firmly in place, in working order and positioned between yourself
and the cutting line.
3. Wear long pants and substantial footwear to protect yourself from
injury caused by flying debris. This is especially important when
edging with the appliance.
Z_SAFETY WARNINGS AND INSTRUCTIONS:
POLARIZED PLUGS
To reduce the risk of electric shock, this equipment has a polarized
plug (one blade is wider than the other). This equipment must be
used with a suitable polarized 2 wire or 3 wire extension cord.
Polarized connections wilt fit together only one way. Make sure that
the receptacle end of the extension cord has large and small blade
slot widths. If the plug does not fit fully into the extension cord,
reverse the plug. Ifit still does not fit, obtain a suitable extension
cord. If the extension cord does not fit fully into the outlet, contact a
qualified electrician to install the proper outlet. Do not change the toot
plug or extension cord in any way.

OPERATING INSTRUCTIONS FOR CATALOG # ST4500
BUMP FEED TRIMMER
LINE FEED
Your trimmer uses .065 in. (1.65 mm) diameter, ROUND nylon line
to cut grass and weeds quickly and easily. Cutting line will wear
faster and require more feeding if the cutting or edging is done
along sidewalks or other abrasive surfaces or heavier weeds are
being cut. As you use the trimmer, the string will get shorter due to
wear. Gently bump the unit on the ground and the line will feed.
z_CAUTION: ALWAYSUSEEYEPROTECTION.
CAUTION: Inspect area to be trimmed and remove any wire,
cord, or string-like objects which could become entangled in the
rotating line or spool. Be particularly careful to avoid any wire which
might be bent outwardly into the path of the toot, such as barbs at
the base of a chain link fence.
1. Angle unit as shown in figure 7.
(10°
3. To convert for maintenance
edging, turn off the toot. Holding
the trimmer (as shown in
figure 9) with one hand by the
auxiliary handle, grasp the
trimmer head collar, push in
direction of arrow and rotate the
trimmer head clockwise (when
viewed from the switch end) until
it stops, (half turn), release your
hand. The toot is locked in the
edger position.
2. Slowly swing trimmer side-to-
side as shown in figure 8.
4. To operate as a maintenance
edger, position trimmer above
sidewalk as shown in figure 10.
5. Return to trimming position by
turning the tool off, pushing in
direction of arrow and rotating the
trimmer head counter clockwise
until it stops.
RELOADING LINE ST4500
USE ONLY .065 in. (1.65mm) DIAMETER NYLON
MONOFILAMENT LINE. Heavier line will overload the motor and
cause overheating. This line is available at your local dealer or
authorized service center.
Do not use fishing line or other
lines that are not recommended.
1. Unplug extension cord at
trimmer.
2. Remove the bump cap by pulling
up while depressing the two
release tabs on the sides of the
hub at the points shown in
figure 11.
NOTE: It may be necessary to
pull up on the cap while
depressing the release tabs one
side at a time.
3. Remove any broken cutting line,
wrap the remaining tine tight and
reinsert spool into hub as
follows.
a.Wind the line tight enough so
that it is all below the edges of
the flanges on the spool. If it
extends past the flanges, it
won't fit into the hub.
b. Place the loose end of the
cutting line through the gap in
the spool flange as shown in
figure 12. (Either gap will do
but try to leave yourself about
3 or 4 inches of line to work
with.)
@
c. Holding the line in the gap,
insert the end through the
eyelet in the hub and slip the
spool into the hub, as shown
in figure 13.
Make sure the spring is still in
place in the hub. If the spool
does not slip into the hub
easily, press gently and pull
straight out on the cutting line
that protrudes through the
eyelet.
4. Once the spool drops into the
hub, align the release tabs on
the shroud with the slots in the
hub as shown in figure 14 and
press the shroud into place. Be
sure that both release tabs
snap into place.
5. To replace the line on a spool,
follow the steps below
a.Locate, on the empty spool,
one of the two small holes
shown in figure 15.
®
II1
i /
b. Insert the end of the line no
more than 1/8 in. into the hole
and begin winding the line
around the spool (figure 16).
Be sure to wind the line in the
direction of the arrow in figure
17. Do not overfill spool. The
spool holds 20 feet (6 m) of
line.
c. Perform steps 3 and 4 above.

OPERATING INSTRUCTIONS FOR CATALOG # ST76(X),
ST7700 AUTO FEED SYSTEM
LINE FEED
Your trimmer uses .065 in. (1.65 mm) diameter, ROUND nylon line
to cut grass and weeds quickly and easily. During use, the tip of the
nylon line wilt become frayed and worn and the special self feeding
line hub wilt automatically feed and trim a fresh length of line.
Cutting line wilt wear faster and require more feeding if the cutting
or edging is done along sidewalks or other abrasive surfaces or
heavier weeds are being cut. The advanced automatic line feeding
mechanism senses when more cutting line is needed and feeds
and trims the correct length of line whenever its required. DO NOT
BUMP unit on ground in attempt to feed line or for any other
purposes.
/h CAUTION: ALWAYS USE EYE PROTECTION.
z_CAUTION: Inspect area to be trimmed and remove any wire,
cord, or string-like objects which could become entangled in the
rotating line or spool. Be particularly careful to avoid any wire which
might be bent outwardly into the path of the toot, such as barbs at
the base of a chain link fence.
1. Angle unit as shown in figure 7.
2. Slowly swing trimmer side-to-side as shown in figure 8.
3. To convert for maintenance edging, turn off the tool. Holding the
trimmer (as shown in figure 9) with one hand by the auxiliary
handle, grasp the trimmer head collar, push in direction of arrow
and rotate the trimmer head clockwise (when viewed from the
switch end) until it stops, (half turn), release your hand. The toot is
locked in the edger position.
4. To operate as a maintenance edger, position trimmer above sidewalk
as shown in figure 10.
5. Return to trimming position by turning the toot off, pushing in
direction of arrow and
rotating the trimmer head counter clockwise until it stops.
CLEARING JAMS AND TANGLED LINES
From time to time, especially when cutting thick or stalky weeds,
the line feeding hub may become clogged with sap or other
material and the line will become jammed as a result. To clear the
jam, follow the steps listed
below. @
1. Press the release tabs on the
line hub cap, as shown in
figure 18 and remove the cap
by pulling it straight off.
2. Lift the spool of nylon line out
of the hub and clear any
broken line or cutting debris
from the spool area. (If you
plan to replace the spool or
rewind it, this is the place to do so, otherwise, move on.)

replacement. Perform steps listed under Option 1 or Option 2,
then continue with steps 4 through 6 below.
4. Insert the line end through the eyelet in the spool hub, as shown
in figure 19. Pull the line through the hole to maintain tension
while placing the spool down into the hub, as shown in figure 20.
5. Press the spool down GENTLY and rotate it until you feel it drop
into place. (When in place, the spool will turn a few degrees left
and right freely). Take care to keep the line from becoming trapped
