TRIMMING PROCEDURES
When properly equipped with a debris shield and line-
head, your unit will trim unsightly weeds and tall grass in
those hard-to-reach areas - along fences, walls, founda-
tions and around trees. It can also be used for scalping to
remove vegetation down to the ground for easier prepara-
tion of a garden or to clean out a particular area.
NOTE: Even with care, trimming around foundations,
brick
or stone walls, curves, etc., will result in above normal line
wear.
TRIMMING / MOWING
Swing trimmer with a sickle-like motion from side to side.
Do not tilt the linehead during the procedure. Test area to
be trimmed for proper cutting height. Keep linehead at
same level for even depth of cut (Fig. 7A).
CLOSER TRIMMING
Position trimmer straight ahead with a slight tilt so bottom
of linehead is above ground level and line contact occurs
at proper cutting point. Always cut away from operator. Do
not pull trimmer in toward operator.
FENCE / FOUNDATION TRIMMING
Approach trimming around chain link fences, picket
fences, rock walls and foundations slowly to cut close
without whipping line against the barrier. If the line comes
in contact with rock, brick walls, or foundations, it will
break or fray. If line snags fencing, it will snap off
.
TRIMMING AROUND TREES
Trim around tree trunks with a slow approach so line does
not contact bark. Walk around the tree trimming from left
to right. Approach grass or weeds with the tip of the line
and tilt linehead slightly forward.
SCALPING
Scalping refers to removal of all vegetation down to the
ground. To do this, tilt the linehead to about a 30 degree
angle to the left. By adjusting the handle you will have bet-
ter control during this operation. Do not attempt this pro-
cedure if there is any chance flying debris could injure
operator, other people or cause damage to property. (Fig.
7B)
REPLACING TRIMMING - LINE STA N D A R D
H E A D
1.
Turn knob (A) COUNTERCLOCKWISE and remove
(Fig. 8A). User knob spanner supplied.
2.
Remove spool (B) and spring (C) from spindle (D).
3.
Remove any remaining cutter line (H).
4.
Double a 14’ (4.3m) length of .080" (2mm) cutter line.
Place the looped center in one of the slots of the
spool divider (Fig. 8B).
5.
W ind cutter line clockwise as shown in illustration
(Fig. 8C), keeping tension, with each half separated
by the spool divider. Wind to within 6" (15cm) of the
ends.
6.
Lock each end of line (H) into a slot (F) on opposite
sides of the spool (Fig. 8D).
7.
Install the spring (C) over the spindle (D). Insert each
end of the line through an eyelet (G) in the housing
(E) (Fig. 8E).
8.
Lower the spool into the housing (E) while feeding the
line through the eyelets (G). Ensure the spring seats
i
tself into the spool (Fig. 8E).
9.
Once the spool is in place, apply pressure on the
spool compressing the spring. Pull each end of the
line (H) sharply to unlock the line from the slots (Fig.
8F).
10. Continue to apply pressure to the spool until the knob
can be threaded CLOCKWISE onto the spindle.
Tighten the knob securely by hand only (Fig. 8G).
11. Trim the excess line to approximately 5" (13cm). This
will minimize load on engine during starting and
warm-up (Fig. 4A).

CAUTION: Periodically remove weed wrap to
prevent overheating the drive shaft. Weed
wrap occurs when strands of weed become
entangled around the shaft beneath the
debris shield (Fig. 6B). This condition pre-
vents the shaft from being properly cooled.
Remove weed wrap with screwdriver or sim-
ilar device.
