Clearing Jams/Tangled Line; Speed Control/Runtime Extension Mode - Black & Decker LST522 Instruction Manual

• Position the edging wheel on the edge of
the sidewalk or abrasive surface so the
cutting line is over the grass or dirt area to
be edged.
• To make a closer cut, slightly tilt the trimmer.

SPEED CONTROL & RUNTIME
EXTENSION MODE
This string trimmer gives you the choice to
operate at a more efficient speed to extend
the runtime for larger jobs, or accelerate the
trimmer speed for high-performance cutting
(figure M).
• To extend runtime, pull the speed-control
switch (4) back toward the battery (12) into
position #1. This mode is best for larger
projects that require more time to complete.
• To accelerate the trimmer, push the
speed-control switch forward toward the
trimmer head (8) into position #2. This
mode is best to cut through heavier growth
and for applications that need higher RPM.
NOTE: When in acceleration mode (#2),
runtime will be decreased as compared to when
trimmer is in extended runtime mode (#1).

HELPFUL CUTTING TIPS
• Use the tip of the string to do the
cutting; do not force string head into
uncut grass. Use edge guide along such
things as fences, houses and flower beds
for best practices.
• Wire and picket fences cause extra string
wear, even breakage. Stone and brick walls,
curbs, and wood may wear string rapidly.
• Do not allow spool cap to drag on ground
or other surfaces.
• In long growth cut from the top down and
do not exceed 12 inches (304.8 mm) high.
• Keep trimmer tilted toward the area being
cut; this is the best cutting area.
• The trimmer cuts when passing the
unit from the right to left. This will avoid
throwing debris at the operator.
• Avoid trees and shrubs. Tree bark, wood
moldings, siding, and fence posts can
easily be damaged by the string.
CUTTING LINE / LINE FEEDING
Your trimmer uses .065 inch (1.65 mm)
diameter, ROUND nylon line. During use,
the tips of the nylon lines will become frayed
and worn and the special self feeding spool
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 it's required. DO
NOT BUMP unit on ground in attempt to
feed line or for any other purposes.
CLEARING JAMS AND TANGLED LINE
(FIGURES N, O, P)
WARNING:
the trimmer before making any assembly,
adjustments or changing accessories. Such
preventive safety measures reduce the risk of
starting the appliance accidentally. 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.
• Remove the battery from the trimmer.
• Press the release tabs (22) on the line
spool cap (23), as shown in figure N and
remove the cap by pulling it straight off.
