Chapter I
Safety and Precautions
For the sake of safety of you, the equipment and the property, before using the machine, please make sure to read this manual
carefully, and strictly follow it in the process of transporting, commissioning, operating and troubleshooting.
1.1 Safety Guide
[1]: The operating personnel must wear the water-proof and insulating work shoes and gloves, and barefooted operation is
prohibited for preventing personal casualty from electric leakage.
[2]: The external connecting wire had better be more than 4m2 and must be connected with the earth wire for preventing
form electric leakage.
[3]: Before using the equipment, must check whether the power wire is damaged or aging. If so, immediately replace the
power wire for preventing the equipment from short circuit and electric leakage.
[4]: The staff sitting on the electric machine of the equipment is prohibited for preventing equipment shut-down for
over-load or personal casualty for electric leakage. Don’t put the equipment, the power and the socket into water or
over-humid environment for preventing the equipment damage from the short circuit.
[5]: When conducting wet grinding, waterproof protection should be conducted for the water tank, inverter and control
panel for preventing the equipment non-operation or personal casualty from equipment short circuit or electric leakage.
[6]: When using the equipment, don’t roll on the electric wire for preventing potential safety risk from electric wire
damage.
[7]: When using the equipment, don’t insert the plug with wet hands for preventing injuries and deaths from electric
shock.
1.2 Precautions
[1]: After dry grinding and wet grinding treatment, there needs to completely clean the bottom part of the equipment so as
to increase the service life.
[2]: When conducting dry grinding on the equipment, please connect the vacuum cleaner, so as to ensure the dust-free
operation, decrease the inverter load and guarantee the equipment’s normal running.
[3]: In the process of replacing consumables and transporting, please be sure to put down the equipment gently for
preventing the strike and oil leakage of the gear box from the improper operation (If one person can’t carry the
equipment easily in the operation process, please look for other people to assist).
[4]: In a certain range of output frequency, the frequency inverter may probably produce the resonance which will cause
the equipment to stop work, under such a circumstance, please avoid the resonant frequency operation.
[5]: When conducting the operation on the floor with a large difference of level, please be sure to grind from the higher to
the lower for preventing the damages for the grinding plate and gear box from oversize difference of level.
[6]: Regularly check the grinding plate, if there finds any loose of the grinding plate, please make timely maintenance.
