It is the user’s obligation to read this manual carefully before using the machine. Detailed instructions on the operation and
maintenance of the machine are presented in this manual and should be strictly followed to prevent accidents. The original
manufacturer will NOT be responsible for any injury and loss caused due to the user’s improper operation.
2.1 Cautions
The operator must be well trained before using the machine, or accidents may take place and injury or loss will be caused.
To avoid fire accidents, the machine can only be used to clean non-explosion-proof ground.
Do NOT use the machine if it is not well assembled, or accidents may take place and injury or loss will be caused. Before
operating the machine, check whether it is complete and well assembled.
Any maintenance and repair must be realized by professional personnel.
Make sure that the power is disconnected before maintaining or repairing the machine.
2.2 Operation instructions
Check the polarities of the batteries repeatedly before wiring them, as wrong connection will cause damage to all the electric
components of the machine and must be prevented.
Use chargers accompanying the batteries, or damage and even explosion will be produced.
Maintenance and repair of the machine must be realized by a professional technician, or accidents and economic loss are likely
to be caused.
Do NOT expose the electric components of the machine to water or damp environments, or they may be short-circuited and
unable to work.
The charging room must be well ventilated. When charging the batteries, use an E-core power cord and power supply with a
ground wire. In order to minimize the odds of electric shocks, please use a residual-current circuit breaker (RCCB).
