and even lead to explosion in extreme cases.
Short circuit may be produced if the electrical components of the
machine are exposed to water or moisture.
Do NOT put any objects on the battery.
Do NOT let any water enter into the inlet of the suction motor when
washing the machine.
Damage may be caused if you do not pay attention to the labels on the
machine and this manual. Read them carefully before operating the
machine.
The machine must NOT advance in a rough ground or slope. Do NOT
sit on the machine and keep your hands, feet and loose clothing away
from any moving part.
Be careful when the machine is moving along the edge (of a wall), and
pay attention to the space between its anti-collision wheel and the wall;
do NOT push the machine over tiny obstacles.
The use of water or detergent will wet the ground and may be prone to
slippery. Put warning signs around during the work.
1.4 Instructions for safety
Since the machine is very heavy, special attention should be paid during
transportation; if you need to transport the machine, the battery must be
taken out first, and lift the metal frame at the bottom of the machine. Do
NOT put your focus on the plastic water tank so as to avoid damage.
Do NOT operate or store the machine (as well as the battery) in places
with explosive gas or liquid.
1.5 Safety requirements for batteries
The battery must NOT be in a low voltage state; charge the battery as
soon as possible when the voltage is below 21 V;
To avoid electric leakage, keep the battery dry and clean;
Do NOT put metallic objects (such as tools) on the battery to prevent it
from being short-circuited and burned;
The charging room should be well ventilated;
When the key switch is in the ON position, do NOT install or remove
the battery;
Before installing or removing the battery, disconnect first the negative
wire (-) and then the positive wire (+). When rewiring, pay special
attention to the polarity of the battery, as wrong connection would likely
damage electrical components inside the battery;
Avoid direct contact between the positive and the negative electrodes,
because it would cause a large current short circuit, high heat or even a
fire.
Attention: disconnect the battery connecting cable if the machine is not about
to be used for a long time or is going to be repaired.
