Battery pack Charger
Y0L120BAT2.5 Y0L120CGR
SPECIAL OPERATION SAFETY FOR THE
CHARGER
1. Recharge only with the charger specied
by the manufacturer. Do not use the original
charger on other li-ion batteries or on any
other type of battery—re or explosion may
occur.
2. Check the battery charger, cable and plug
each time before using. Do not use the
battery charger when defects are detected.
Do not open the battery charger yourself and
have it repaired only by qualied personnel
using original spare parts.
3. The charger is designed to use standard
household 100~120 V, 50/60 Hz power
source. The charger’s plug must match the
outlet. Never modify the plug in any way.
Unmodied plugs and matching outlets will
reduce risk of electric shock.
4. Do not abuse the cord of charger. Never use
the cord for carrying, pulling or unplugging
the charger. Keep cord away from heat, oil,
sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric
shock.
5. Make sure the charger cord is located so
that it will not be stepped on, tripped over, or
otherwise subjected to damage or stress.
6. Keep the battery charger clean.
Contamination may cause the danger of
electric shock.
7. Protect the battery charger from rain and
moisture. The penetration of water in a
battery charger increases the risk of electric
shock.
8. Do not operate the battery charger on easily
inammable surfaces (e.g. paper, textiles,
etc.) or in combustible environments. There
is danger of re due to the heating of the
battery charger during charging.
12
9. The temperature range over which the
battery pack can be charged is typically 41
˚
F
- 113
˚
F. Therefore, charging eorts 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 rstly.
2. The battery pack should be recharged when
it fails to produce sucient 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 re. 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
re, 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 re extinguisher must be
used.
8. If the battery pack becomes too hot to the
touch during charging, disconnect and switch
o 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 re.
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
