2. Safety Rules And Cautions
• Make sure service voltage complies with rated voltage in parameter label.
• Check if there’s any damage on electrical elements. If yes, only the
maintenance staff of the manufacturer or similar specialists can replacer
or repair it in case of any possible hazard.
• To ensure a clean tank, make sure the accessories are installed tightly and
nothing is blocking the passage.
• Check if the suction is regular, instead of too weak.
• Filter bags need to be used only when using the dust suction function and
must be removed before wetting suction.
• Direction of power switch must be the same as direction of the square
hose holder.
• Don’t absorb anything that could block the passage easily, such as hair,
large paper lumps, etc.
• Some defoamer additive solution is needed in the tank while working at
location with much foam.
• Power cord mustn’t be extended artificially or circled during use.
• Top part, including motor, must be taken off before emptying liquid in the
tank, instead of turning over the entire machine.
• Tank, filter bags and any related functional accessories must be cleaned
up after each use. While cleaning the filter bag, some cleanser is required.
• Dirty or wet filter bags should not be used. Similarly, filter bags with holes
or cracks should not be used either.
• Don’t forget to hang the power cord on the special hook after each use.
• Please be gentle when using the machine, do not force it passed its
capacities.
• The machine must be kept in a dry place after use.
• While cleaning machine, a wet cloth is needed and top part with motor
mustn’t be immersed in water
• Caustic cleansers, like gasoline or isoamyl acetate, are not allowed in case
of any surface crack.
UNINTERRUPTED WORKING TIME SHOULDN’T BE BEYOND 2 HOURS,

according to cleaning demands.
