OPERATING INSTRUCTIONS FOR CATALOG # ST7600,
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 will become frayed and worn and the special self feeding
line hub will automatically feed and trim a fresh length of line.
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. 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.
CAUTION: ALWAYS USE EYE PROTECTION.
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 tool, 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 tool 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 tool 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.)
