Safety instructiones

Never operate the equipment with the stirrer tools rotating
freely. Ensure that parts of the body, hair or items of clothing
cannot be trapped by the rotating parts. Pay attention when
setting the speed to any imbalance of the stirrer tools and
possible spraying of the medium to be stirred. Use a stirrer shaft
protection device!
10
The equipment is not suitable for manual operation. Please follow
the relevant safety instructions and guidelines, and occupational
health and safety regulations for use in the laboratory.

Avoid knocks and impacts on the lower end of the shaft and the
10
chuck gear teeth. Even minor, invisible damage can lead to im-
11
balance and uneven shaft action. Careful handling guarantees
11
safe working and the long life of the equipment.
11
Imbalance of the output shaft, the chuck and in particular the
11
stirring tools can lead to uncontrolled resonant vibrational
12
behaviour of the equipment and the whole assembly. Glass
12
apparatus and stirrer containers can be damaged or shattered by
12
this. It can cause injury to the operator, as can the rotating stirring
13
tool. If vibration of the equipment is noticed, the speed must be
13
reduced immediately in all cases until no more vibration occurs.
13
In this case exchange the stirring tool for one without imbalance
13
or remedy the cause of the imbalance.
14
15
Operating with a freely rotating shaft end is dangerous. Therefore
15
for safety reasons the stirrer tool is permitted to project over the
15
upper edge of the housing only when the machine is not running.
15
82
The unit must be switched off before changing to another gear
83 / 84
speed, otherwise the toothed gears in the reduction stage will be
damaged.
The machine may only be opened by trained specialists - even
during repairs. The machine is to be unplugged from the mains
before opening. Live parts inside the machine may still be live for
some time after unplugging from the mains.
The high torque developed by the RW 20 DZM.n P4 requires
particular care in the choice of stand, cross sleeve and anti-
rotation element for the stirring bowl.
