I. Notice to users
1.Please read the manual carefully before using the sweeper for the first time; please
keep the manual for reference by other users.
2.Before using the sweeper, please check whether all parts are in good condition. If
there is any problem, please contact the dealer in time.
3.This machine can't wade in water, wash directly or without protection in heavy rain
and snow to avoid damage caused by water entering internal electrical components.
4.This machine uses DC power, but
(1) Do not touch the charging socket with wet hands;
(2) Do not touch the positive and negative electrodes of the charging socket with
hands or metal objects at the same time.
5. Please do not use the battery energy to the lowest voltage (under voltage recovery
value) when using it every time. If the battery is often used, the deep discharge in
this situation will seriously affect the service life of the battery. In addition, we should
try our best to avoid the phenomenon of insufficient electricity or charging, as well as
long-term storage without charging after use. It is hoped that the user can fully charge
the battery in time and charge it as soon as it is used. If it is not used for a long time,
the battery should be stored after being fully charged and replenished regularly
(generally no more than 30 days).
6. All batteries will be affected by temperature. When the temperature is high, the
discharge performance of the battery is good and the capacity is high. When the
temperature is below 0 ℃ , the capacity of the battery will decrease by more than
1 / 3. In all severe cold weather, the mileage of the battery will be reduced after one-
time charging, which is a normal phenomenon; when the temperature rises, the
battery function will naturally return to normal.
7. In summer, it is necessary to prevent the machine from being exposed to the sun for
a long time, otherwise, if the temperature exceeds 60 ℃ , the electrical appliances of
the machine may not work normally.
8. If the machine is suddenly cooled from cold to hot, the electronic components will
be dewed. The condensation should be eliminated before the machine is installed.
9. For the safety of others, please do not lend the sweeper to people who can't operate
it, especially minors.
10. The machine should be used correctly. Attention should be paid to the use
conditions and traffic safety
11. Please do not disassemble the machine by yourself. If there is any problem, please
contact the dealer
