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 type of work. To reduce your exposure to these
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.
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
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 attachment and guard, always turn the
tool off and 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.

3. To avoid kickback:
−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.
