Bump Feed Trimmer Line Feed

WARNING: To avoid personal injury, never bump the
unit when the brush cutter assembly is attached to the
motorhousing.
Your trimmer uses 2.032 mm diameter nylon line. Cutting line
will wear faster and require more feeding if the cutting 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 trimmer on the ground while running at
normal speed and the line willfeed.
NOTE: Extending nylon line beyond the 330mm swath will
negatively affect performance, runtime, and the life of the
trimmer due to potential of damaging motor. Doing so may
void thewarranty.
Helpful Cutting Tips
• Use the tip of the string to do the cutting; do not force string
head into uncutgrass.
• 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
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 left to
right. 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.

Replacing the Cutting Line (Fig. P–S)

CAUTION: To avoid appliance damage, if the cutting line
protrudes beyond the trimming blade, cut it off so that it
just reaches theblade.
1. Removebattery.
2. Turn spool
36
clockwise to unlock as shown in figure P. The
white nub
37
inside the spool will rotate away from the
spool window
38
to indicate it isunlocked.
3. Pull the spool straight out toremove.
4. Remove any dirt and grass from the spool andhousing.
5. First, wind new line in the channel of the spool closest to
the holding slots
39
as shown in figureQ.
6. Place the end of the cutting line
40
into the retaining
hole
41
.
7. Wind the cutting line onto the spool in the direction of the
arrow on the bottom of thespool.
8. When the wound cutting line reaches the beginning of the
holding slots, cut the line approximately 106mm.
9. Push the line in the holding slots on one side of the spool to
hold the first line while you wind the second line.
10. Repeat the above procedure for the second cutting line on
the lower section of the spool.

CAUTION: Before you begin trimming, only use the
appropriate type of cutting line. Ensure that cutting line is
present in both sections of the spool as shown in FigureR.
11. Once both lines are wrapped around the spool
36
, place
your thumb and finger on the holding slots to further secure
the string and feed the end of each line through the two
holes
43
on either side of the head in the spool housing
12
as shown in figureS.
12. Line up the white nubs
37
inside the spool housing with
the recesses
42
of the spool. Align the holding slots
39
with the two holes
43
as close aspossible.
13. Push the spool into the spool housing and turn
counterclockwise to lock the spool in place. Ensure the
white nub
37
appears in the spool window
38
. Make sure
the line doesn't unravel and wrap around the shaft below
thespool.
14. Pull both ends of the cutting line to release them from the
holding slots. If the line extends past the cutting blade on the
guard cut the line so it just reaches theblade.
