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 nor-
mal string 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. 8A).
Fig. 8A
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 string 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 string
and tilt linehead slightly forward.
WARNING: Use extreme caution when
SCALPING. Keep a distance of 100 feet (30
meters) between operator, other people and
animals during these operations.
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 right. By adjusting the handle you will have
better control during this operation. Do not attempt this
procedure if there is any chance flying debris could injure
operator, other people or cause damage to property (Fig.
8B)
Fig. 8B
WARNING: DO NOT SWEEP WITH TRIMMER
Sweeping refers to tilting linehead to sweep
away debris from walkways, etc. Your trim-
mer is a powerful tool and small stones or
other such debris may be hurled 50 feet (15
meters) or more, causing injury or damage to
nearby property such as automobiles, homes
and windows.

1. Loosen knob (B) by turning counter clockwise (Fig.
8C).
2. Push down release lever (A) and twist shaft to desired
position (Fig. 8C). Edging holes positioned at 90
degrees left, 90 degress right and 180 degrees.
3. Lock lower shaft in desired edging hole with release
lever.
4. Tighten knob (B)securely before use by turning clock-
wise.
TOOL-LINK ATTACHMENTS:
1. Loosen knob (B) by turning counter clockwise (Fig.
8D).
2. Push down release lever (A) and remove lower shaft
(Fig. 8D).

MAINTENANCE INSTRUCTIONS
•
REPLACING TRIMMING LINE
1.
Turn the knob (A) CLOCKWISE and remove it (Fig.
9A).
2.
Remove the spool (C), and spring (D) from spindle
(E)
3.
Remove any remaining trimming line.
4.
Double a 32' (9.8m) length of .095 (2.5mm) cutter
line. Place the looped center in one of the slots (G) of
the spool divider (Fig. 9B).
5.
Wind as shown in illustration (Fig. 9C), keeping ten-
sion, with each half separated by the spool divider.
Wind to within 6" (15cm) of the ends.
6.
Lock each end of line into a slot (H) on opposite sides
of the spool (Fig. 9D).
7.
Install the spring (D) over the spindle (E). Insert each
end of the line through an eyelet (H) in the housing
(F) (Fig. 9E).
8.
Lower the spool into the housing (F) while feeding the
line through the eyelets (H). Ensure the spring seats
itself into the spool (Fig. 9E).
9.
Once the spool is in place, apply pressure on the
spool compressing the spring. Pull each end of the
line (K) sharply to unlock the line from the slots (Fig.
9F).
10. Continue to apply pressure to the spool until the knob
can be threaded COUNTER CLOCKWISE onto the
spindle. Tighten the knob securely by hand only (Fig.
9G).
11. Trim the excess line to approximately 5" (13cm). This
will minimize load on engine during starting and

11A).
Fuel Filter:
Fig. 9C
1.
Lift fuel line (B) out of tank. A steel wire (C) with a
hook or a paper clip works well (Fig. 11B).
2.
Pull off with a twisting motion (Fig. 11C).
3.
Replace fuel filter (D) (Fig. 11C).
