Work area safety
1. Operate the tool under good visibility and daylight
conditions only. Do not operate the tool in darkness or
fog.
2. Do not operate the tool in explosive atmospheres,
such as in the presence of flammable liquids, gases or
dust. The tool creates sparks which may ignite the
dust or fumes.
3. During operation, never stand on an unstable or
slippery surface or a steep slope. During the cold
season, beware of ice and snow and always ensure
secure footing.
4. During operation, keep bystanders or animals at least
15 m away from the tool. Stop the tool as soon as
someone approaches.
5. Before operation, examine the work area for stones or
other solid objects. They can be thrown or cause
dangerous kickback and result in serious injury and/or
property damage.
6. WARNING: Use of this product can create dust
containing chemicals which may cause respiratory or
other illnesses. Some examples of these chemicals
are compounds found in pesticides, insecticides,
fertilizers and herbicides. Your risk from these
exposures varies, depending on how often you do this

chemicals: work in a well ventilated area, and work
with approved safety equipment, such as those dust
masks that are specially designed to filter out
microscopic particles.
Electrical and battery safety
1. Do not expose the tool to rain or wet conditions. Water
entering the tool will increase the risk of electric shock.
2. Do not use the tool if the switch does not turn it on and
off. Any tool that cannot be controlled with the switch
is dangerous and must be repaired.
3. Prevent unintentional starting. Ensure the switch is in
the off-position before installing a battery pack, picking
up or carrying the tool. Carrying the tool with your
finger on the switch or energising the tool that have
the switch on invites accidents.
4. Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type of
battery pack may create a risk of fire when used with
another battery pack.
5. Use the tool only with specifically designated battery
packs. Use of any other battery packs may create a
risk of injury and fire.
6. When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys, nails,
screws or other small metal objects, that can make a
connection from one terminal to another. Shorting the
battery terminals together may cause burns or a fire.
7. Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, flush with water. If liquid contacts eyes, seek
medical help. Liquid ejected from the battery may
cause irritation or burns.
Putting into operation
1. Before assembling or adjusting the tool, remove the
battery cartridge.

9
2. Before handling the cutter blade, wear protective
gloves.
3. Before installing the battery cartridge, inspect the tool
for damages, loose screws/nuts or improper
assembly. Sharpen blunt cutter blade. If the cutter
blade is bent or damaged, replace it. Check all control
levers and switches for easy action. Clean and dry the
handles.
4. Never attempt to switch on the tool if it is damaged or
not fully assembled. Otherwise serious injury may
result.
5. Adjust the shoulder harness and hand grip to suit the
operator’s body size.
6. When inserting a battery cartridge, keep the cutting
attachment clear of your body and other object,
including the ground. It may rotate when starting and
may cause injury or damage to the tool and/or
property.
7. Remove any adjusting key, wrench or blade cover
before turning the tool on. An accessory left attached
to a rotating part of the tool may result in personal
injury.
Operation
1. In the event of an emergency, switch off the tool
immediately.
2. If you feel any unusual condition (e.g. noise, vibration)
during operation, switch off the tool. Do not use the
tool until the cause is recognized and solved.
3. The cutting attachment continues to rotate for a short
period after turning the tool off. Don’t rush to contact
the cutting attachment.
4. During operation, use the shoulder harness. Keep the
tool on your right side firmly.
5. Do not overreach. Keep proper footing and balance at
all times. Watch for hidden obstacles such as tree
stumps, roots and ditches to avoid stumbling.
6. Never work on a ladder or tree to avoid loss of control.
7. If the tool gets heavy impact or fall, check the
condition before continuing work. Check the controls
and safety devices for malfunction. If there is any
damage or doubt, ask our authorized service center
for the inspection and repair.
8. Do not touch the gear case. The gear case becomes
hot during operation.
9. Take a rest to prevent loss of control caused by
fatigue. We recommend taking a 10 to 20-minute rest
every hour.
10. When you leave the tool, even if it is a short time,
always remove the battery cartridge. The unattended
tool with the battery cartridge installed may be used by
unauthorized person and cause serious accident.
11. If grass or branches get caught between the cutting

remove the battery cartridge before cleaning.
Otherwise the cutting attachment may rotate
unintentionally and cause serious injury.
12. If the cutting attachment hits stones or other hard
objects, immediately turn the tool off. Then remove the
battery cartridge and inspect the cutting attachment.
13. Check the cutting attachment frequently during
operation for cracks or damages. Before the
inspection, remove the battery cartridge and wait until
the cutting attachment stops completely. Replace
damaged cutting attachment immediately, even if it
has only superficial cracks.
14. Never cut above waist height.
15. Before starting the cutting operation, wait until the
cutting attachment reaches a constant speed after
turning the tool on.
16. When using metal blades, swing the tool evenly in
half-circle from right to left, like using a scythe.
17. Hold the tool by insulated gripping surfaces only,
because the cutter blade may contact hidden wiring.
Cutter blades contacting a “live” wire may make
exposed metal parts of the tool “live” and could give
the operator an electric shock.
Cutting attachments
1. Use an applicable cutting attachment for the job in
hand.
– Nylon cutting heads (string trimmer heads) are
suitable for trimming lawn grass.
– Metal blades are suitable for cutting weeds, high
grasses, bushes, shrubs, underwood, thicket, and
the like.
– Never use other blades including metal multi-piece
pivoting chains and flail blades. It may result in
serious injury.
2. Always use the cutting attachment guard properly
suited for the cutting attachment used.
3. When using metal blades, avoid “kickback” and
always prepare for an accidental kickback. See the
section “Kickback.”
4. When not in use, attach the blade cover onto the
blade. Remove the cover before operation.
Kickback (Blade thrust)
1. Kickback (blade thrust) is a sudden reaction to a
caught or bound cutting blade. Once it occurs, the tool
is thrown sideway or toward the operator at great force
and it may cause serious injury.
2. Kickback occurs particularly when applying the blade
segment between 12 and 2 o’clock to solids, bushes
and trees with 3 cm or larger diameter. (Fig. 2)
3. To avoid kickback: (Fig. 3)
– Apply the segment between 8 and 11 o’clock.
– Never apply the segment between 12 and 2
o’clock.
– Never apply the segment between 11 and 12
o’clock and between 2 and 5 o’clock, unless the
operator is well trained and experienced and does it
at his/her own risk.
– Never use cutting blades close to solids, such as
fences, walls, tree trunks and stones.
– Never use cutting blades vertically, for such
operations as edging and trimming hedges.
Vibration
1. People with poor circulation who are exposed to
excessive vibration may experience injury to blood
vessels or the nervous system. Vibration may cause
the following symptoms to occur in the fingers, hands
or wrists: “Falling asleep” (numbness), tingling, pain,
stabbing sensation, alteration of skin color or of the
skin. If any of these symptoms occur, see a physician!

10
2. To reduce the risk of “white finger disease”, keep your
hands warm during operation and well maintain the
tool and accessories.
Transport
1. Before transporting the tool, turn it off and remove the
battery cartridge. Attach the cover to the cutting blade.
2. When transporting the tool, carry it in a horizontal
position by holding the shaft.
3. When transporting the tool in a vehicle, properly
secure it to avoid turnover. Otherwise damage to the
tool and other baggage may result.

menyebabkan bagian logam yang terbuka pada mesin
ikut teraliri arus listrik dan menyengat pengguna.

20
Alat tambahan pemotong
1. Gunakan alat tambahan pemotong yang tepat untuk
pekerjaan yang dilakukan.
– Head pemotongan nilon (head pemangkas senar)
sesuai untuk memangkas rumput halaman.
– Bilah logam sesuai untuk memotong gulma, rumput
tinggi, semak, belukar, pohon pendek, perdu, dan
sejenisnya.
– Jangan sekali-kali menggunakan bilah lain
termasuk rantai logam putar multi-keping dan bilah
perontok (flail blade). Penggunaan bilah demikian
dapat mengakibatkan cedera serius.
2. Selalu gunakan pelindung alat tambahan pemotong
yang sesuai untuk alat tambahan pemotong yang
digunakan.
3. Bila menggunakan bilah logam, hindari
“tendang-balik” dan selalu persiapkan diri untuk
menghadapi tendang-balik yang tidak disengaja. Lihat
bagian “Tendang-balik.”
4. Bila mesin tidak sedang digunakan, pasang penutup
bilah pada bilah. Lepaskan penutup sebelum
digunakan.
Tendang-balik (Hentakan bilah)
1. Tendang-balik (hentakan bilah) adalah reaksi tiba-tiba
terhadap tersangkut atau terjepitnya bilah pemotong.
Saat hal itu terjadi, mesin terlempar ke samping atau
ke arah operator dengan kekuatan besar dan dapat
menyebabkan cedera serius.
2. Tendang-balik terjadi khususnya bila mengaplikasikan
segmen bilah di arah antara pukul 12 dan 2 pada
benda padat, semak, dan pohon dengan diameter
3 cm atau lebih. (Gb. 2)
3. Untuk menghindari tendang-balik: (Gb. 3)
– Aplikasikan segmen antara pukul 8 dan 11.
– Jangan sekali-kali mengaplikasikan segmen di arah
antara pukul 12 dan 2.
– Jangan sekali-kali mengaplikasikan segmen bilah
di arah antara pukul 11 dan 12 dan antara pukul 2
dan 5, kecuali jika operator telah terlatih baik dan
berpengalaman, dan itu pun dengan risiko
ditanggung sendiri.
– Jangan sekali-kali menggunakan bilah pemotong di
dekat benda padat, seperti pagar, dinding, batang
pohon, dan batu.
– Jangan sekali-kali menggunakan bilah pemotong
secara vertikal, untuk pekerjaan seperti merapikan
dan memangkas tepi tanaman.
Getaran
1. Orang dengan kondisi sirkulasi darah kurang baik
yang terpapar pada getaran berlebihan dapat
mengalami cedera pada pembuluh darah atau sistem
sarafnya. Getaran dapat menyebabkan timbulnya
gejala-gejala berikut ini pada jari, tangan, atau
pergelangan tangan: “Mati rasa” (baal), kesemutan,
nyeri, sensasi seperti tertusuk, perubahan kulit atau
warna kulit. Jika ada di antara gejala ini yang timbul,
hubungi dokter!
2. Untuk mengurangi risiko “white finger disease”
(penyakit jari putih), jaga tangan Anda selalu hangat
