CAUTION
○ The case must be securely attached to the cover.
○ Check the cover, case and other components for cracks
or other damage.
○ Check the case and button for wear.
If the wear limit mark on the case is no longer visible or
there is a hole in the bottom of the button, change the
new parts immediately. (Fig. 25)
○ The nylon head must be securely mounted to the
threaded fastener of the motor case.
○ For outstanding performance and reliability, always
use Hitachi nylon cutting line. Never use wire or other
materials that could become a dangerous projectile.
○ If the nylon head does not feed cutting line properly,
check that the nylon line and all components are
properly installed. Contact your Hitachi dealer if you
need assistance.
2. Installation (Fig. 18 and 23)
(1) Insert the fl ange assy into the motor case. At this time,
the wing of the fl ange assy should face the motor case
side. Next, align the holes of the fl ange assy and the
motor case, insert the hex. bar wrench 4 mm, and then
turn to tighten the fl ange assy.
(2) Screw the nylon head directly to the threaded fastener of
the motor case.
The mounting nut of nylon head is left-hand-threaded.
Turn clockwise to loosen/ counterclockwise to tighten.
CAUTION
Install the nylon head properly and securely as instructed
in the handling instructions.
If not attached properly or securely, it may come off and
cause injury.
3. Adjustment of line length
Rotate and tap the nylon head on the ground. Nylon line
is drawn out abt, 30 mm by one tapping. (Fig. 24)
Also, you can extend nylon line with hands. This time the
motor must be completely stopped.
Confi rm the line extends in 30 mm increments by
"tapping" and "releasing" the bottom button while pulling
the line ends of the nylon head. (Fig. 25)
○ Appropriate Length of Nylon Line
The appropriate length of the line when the tool is in use
is 90 – 110 mm. Extend the line to the appropriate length.
4. Nylon line replacement
(1) Prepare 4m of genuine nylon line in Fig. 22. (Code No.
335235)
(2) Press the opposing tabs, and then remove the cover
from the case. (Fig. 26)
(3) Remove the reel from the case. (Fig. 27)
○ If there is nylon line remaining, hook the line in the
groves, and then remove the reel.
○ If the nylon line does not extend when there is enough
nylon line remaining, or when replacing the nylon
line (Code No. 335235), wind the nylon line using the
following procedure.
(4) Release about 150 mm of the nylon cord from both ends,
fold the middle part and attach to the hook on the spool.
Next, wind the cord on the spool in the direction shown
by the arrow, being careful not to crisscross it (Fig. 28,
29).
(5) Leave about 100 mm – 150 mm nylon cord unwound,
hook and secure the line in the stopper. (Fig. 30)
NOTE
Do not cross the nylon line when securing the line in the
Size of
stopper. (Fig. 31)

P1.25-LH
lightly, and then string the line through the eyelet line
guide. (Fig. 32)
(7) Press and snap the tabs of the case in the locking holes
of the cover. (Fig. 33)
WARNING
Check to make sure the tabs are fi rmly snapped into the
locking holes.
Operating the tool while the parts are not fi rmly snapped
together may results in accidents or injury from fl ying
part.
(8) Pull the line taught so there is no slack, and then cut
the line to an extended length of 90 mm – 110 mm with
scissors. (Fig. 34)

OPERATION

Trimming grass
WARNING
○ Do not operate the tool at night or under bad weather
conditions when visibility is poor.
○ Do not operate the tool when it is raining or right after it
has been raining.
○ Wear proper footwear to prevent slipping that could
cause you to lose your balance and fall.
○ Do not use the tool on steep slopes.
When trimming grass on slopes that are not so steep,
trim by moving towards the ridge.
○ Place the right hand on the handle and the left hand on
the loop handle and hold it fi rmly.
○ Take care not to move the nylon head too close to your
feet.
○ Do not raise the nylon head above your knee during
cutting.
○ Do not use the tool where the nylon head may come into
contact with stones, tree and other obstacles.
○ A nylon head can injure while it continues to spin after
the motor is stopped. When the unit is turned off , make
sure the nylon head has stopped before the unit is set
down.
○ Do not use the tool within 15 m of another person. When
you work with someone else, maintain a distance of
more than 15 m.
○ Blade thrust may occur when the spinning blade contacts
a solid object in the critical area.
A dangerous reaction may occur causing the entire unit
and operator to be thrust violently. This reaction is called
blade thrust. As a result, the operator may lose control
of the unit which may cause serious or fatal injury. Blade
thrust is more likely to occur in areas where it is diffi cult
to see the material to be cut.
1. Insert the battery while observing its polarities.
2. Turn on the tool. (Fig. 35)
