battery charger increases the risk of electric
shock.
8. Do not operate the battery charger on easily
inflammable surfaces (e.g. paper, textiles,
etc.) or in combustible environments. There
is danger of fire due to the heating of the
battery charger during charging.
9. The temperature range over which the
battery pack can be charged is typically 41
˚
F
- 113
˚
F. Therefore, charging efforts outside
the prescribed temperature range may
automatically be blocked by the protection
circuitry of the battery pack. Longest life and
best performance can be obtained if the
battery pack is charged in the normal room
condition.
10. Disconnect charger from the power supply
when not in use. This will reduce the risk of
electric shock or damage to the charger if
metal items should fall into the opening.
11. The charger is for indoor use only.
SPECIAL OPERATION SAFETY FOR THE
BATTERY PACK
1. The Li-ion battery pack is not fully charged
at the factory. Before attempting to use it ,it
must be fully charged firstly.
2. The battery pack should be recharged when
it fails to produce sufficient power on jobs
which were easily done previously. DO NOT
CONTINUE using product with its battery in a
depleted condition.
3. Do not charge the battery in an air
temperature below 41
˚
F or above 113
˚
F.
This is important and will prevent serious
damage to the battery. Longest life and best
performance can be obtained if the battery is
charged when air temperature is about 68
˚
F.
4. When the machine continues to be used and
the battery temperature is above 113
˚
F, the
battery can not be charged, even you put on
the charger. Let the machine cool for some
times and wait the temperature reduced, it
can be charged again .
5. Protect the battery pack against heat, e.g.
including against continuous sun irradiation
and fire. There is a danger of explosion.
6. Do not carry individual battery packs in your
pockets or bags, as they could short-circuit
against other metal items.
7. If an exposed li-ion battery pack dose start a
fire, it wll burn even more violently if it comes
into contact with water or even the moisture
in the air. DO NOT throw water on a burning
li-ion battery! A fire extinguisher must be
used.
8. If the battery pack becomes too hot to the
touch during charging, disconnect and switch
off immediately. Contact Service Centre
directly.
9. Do not open the battery yourself. There is
danger of a short circuit.
10. When battery pack is not in use, keep it
away from other metal objects, lie paperclips,
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.
MAINTENANCE AND STORAGE
1. Keep all nuts, bolts and screws tight to be
sure the product is in safe working condition.
2. Check the grass collector frequently for wear
or deterioration.
3. Be careful during adjustment of the product
to prevent entrapment of the fingers between
moving blades and fixed parts of the product.
4. Always allow the product to cool down before
storing.
5. When servicing the blades, be aware that
even though the power source is switched
off, the blades can still be moved.
6. Replace worn or damaged parts for safety.
Use only genuine replacement parts and
accessories.
7. DO NOT attempt to open the charger
and battery pack. There are no customer
serviceable parts inside. Return to any
authorized service center.
8. Store the appliance with battery pack
fully charged at the room temperature
(around 68
˚
F).
9. Every deep discharge cycle decrease the
capacity of battery pack. To prolong battery
life, recommend to charge the battery every
6 months, which over extended periods of
time without use.
