Safety instructions

• Make certain that the unit is set at the lowest 

speed before commissioning; otherwise, the 

unit will begin running at the speed last set. 

Gradually increase the speed.

• Reduce the speed if the medium splashes out of 

the vessel because the speed is too high.

• Before switching on the dispersing instrument 

make sure that its shaft is immersed min. 45 

mm in the medium to prevent the medium 

from splashing out.

• The distance between the dispersion tool and 

the vessel bottom should not be less than 10 

mm (fi g. 1).

• Ensure that the stand does not start to move.

• 

In the event of unbalance or unusual noises, 

switch off the appliance immediately. Replace 

the dispersing element. If there is no difference 

after the change of the dispersing tool, return it 

to the dealer or the manufacturer along with a 

description of the fault.

• Do not touch rotating parts during operation.

• 

Caution: Burns hazard! 

When in operation, 

the dispersing element and the coupling fl ange 

can become hot.

• Do not cover the ventilation slots on the drive in 

order to ensure adequate cooling of the drive.

• Do not process any fl ammable or combustible 

materials.

  •  Process  pathogenic  materials  only  in  closed 

vessels under a suitable extractor hood. Please 

contact 

IKA

®

 if you have any questions.

• Do not operate the appliance in explosive at-

mospheres, with hazardous substances or un-

der water.

• There may be electrostatic discharges between 

the medium and the dispersing instrument 

shaft which could pose a direct danger.

• Only process media that will not react dange-

rously to the extra energy produced through 

processing. This also applies to any extra ener-

gy produced in other ways, e.g. through light 

irradiation.

• Meter powder not too close to the fl ange. Pow-

der can be blown away by air turbulences of 

the drive.

•

 Safe operation is only guaranteed with the ac-

cessories described in the ”Accessories” chapter.

•  Always  disconnect  the  plug  before  fi tting  ac-

cessories.

• The appliance can only be disconnected from 

the mains supply by pulling out the mains plug 

or the connector plug.

For your protection

•

Read the operating instructions in full be-

fore starting up and follow the safety ins-

tructions.

• Keep the operating instructions in a place whe-

re they can be accessed by everyone.

• Ensure that only trained staff work with the ap-

pliance.

• Follow the safety instructions, guidelines, occu-

pational health and safety and accident preven-

tion regulations.

•    Wear  your  personal  protective  equipment  in 

accordance with the hazard category of the 

media to be processed. Otherwise there is a 

risk from:

- splashing and evaporation of liquids

- body parts, hair, clothing and jewellery get-

ting caught.

• Set up the stand in a spacious area on an even, 

stable, clean, non-slip, dry and fireproof sur-

face.

•  Check  the  appliance  and  accessories  before-

hand for damage each time you use them. Do 

not use damaged components.

• The appliance is not suitable for manual ope-

ration.

• The agitation vessels used for dispersing have 

to be secured. Consider on a good stability of 

the entire structure.

• Secure the agitation vessel against twisting.

•  Check  that  the  turning  knobs  are  secure  and 

tighten if necessary.

•  Glass  vessels  must  always  be  secured  with  a 

clamp to prevent them spinning. When wor-

king with flasks elastic couplers must be used 

to prevent fracture of the glass.

• Note the operating instructions of the disper-

sing tool and accessories.

•  Only  dispersing  elements  approved  by 

IKA

®

may be used.

• Please observe the permitted speed for the dis-

persing element. Never set higher speeds.

• Do not use the appliance without a dispersing 

element.

• Use the dispersing tool always inside the stirring 

vessel.

•  Never  run  dispersion  tools  dry,  as  the  gasket 

and bearings will be destroyed if the tools are 

not cooled by the medium.

• 

Caution: Burns hazard!

 If a dispersing element 

is not inserted into the drive fl ange as far as the 

mark it can become extremely hot in operation 

and thus suffer damage.

DANGER!
