Safety regulations (table)
for the BB 51 with reference to the individual chapters
Subject Action
Hazard
Modifications to the machine
Do not modify the machine in any way, and use only
spare parts and accessories approved by Retsch.
The conformity with European Directives de-
clared by Retsch will otherwise be invalidated.
This will lead to all warranty claims being rendered
null and void..
Safety
Failure to observe the notes on safety can lead to dam-
age to property and personal injury.
We accept no liability whatsoever for any damage or in-
jury resulting from non-observance of the notes on
safety.
Packing
Please keep the packing for the duration of the guaran-
tee period.
Return of goods in inadequate packing may jeopardise
your entitlements under the guarantee.
Transport
The BB 51 must not be thrown or otherwise subjected
to impact or vibration during transport.
Electrical and mechanical components may be damaged.
Temperature fluctuations
When there is a likelihood of temperature fluctuations
the BB 51 must be protected against condensation.
Electrical components may be damaged.
Scope of supply
In cases of incomplete delivery and/or transport dam-
age, you must notify the forwarding agent and Retsch
GmbH without delay (within 24 hours).
It may not be possible to accept subsequent complaints.
Ambient temperature
Not below 5°C.
Not above 40°C.
Electrical and mechanical components may be damaged
and performance data change to an unknown extent.
Humidity
Maximum relative humidity 80% at temperatures up to
31°C or 50% (decreasing in a straight line) at 40°C.
Electrical and mechanical components may be damaged
and performance data change to an unknown extent.
Electrical connection
Mains power differs from the values on the type plate. Electrical components may be damaged.
Operation
When starting, stopping or interrupting the operation
of the machine, ensure that the crushing chamber and
feed hopper are empty..
Mechanical components may be damaged by blockage..
Gap width adjustment
Adjustment should be carried out regularly so as to en-
sure that the indicator display and the actual gap width
tally. The greater the load on the BB 51 and the harder
and more abrasive the input material, the more often a
zero point adjustment must be carried out in order to
compensate for wear.
The reading on the indicator display will otherwise
not tally with the actual gap width
.
The BB 51 must only be adjusted when the machine is
empty.
Mechanical components may be damaged by blockage.
Feeding in the input material
Feed material into the hopper only when the machine
is in operation..
Mechanical components may be damaged.
The maximum quantity of input material is limited by
the capacity of the withdrawable receptacle. The useful
capacity of the receptacle will depend on the properties
of the input material. Remember to empty the recepta-
cle in good time.
Crushed material must not be allowed to back up in
the crusher chamber
.
Mechanical components may
otherwise be damaged.
Interrupting the crushing process
The BB 51 must only be stopped when there is no
more input material in the hopper and crushing cham-
ber.
Mechanical components might otherwise jam and
be damaged when the machine is restarted.
Emptying the drawer
When emptying the withdrawable receptacle
L
first
ensure that the B 51 has run empty before stopping it,
ie. that there is no more input material in the crushing
chamber or the feed hopper.
The crushed material will otherwise fall into the
drawer recess rather than into the receptacle.
Be sure to always empty the drawer in good time so
that the top of the heap of crushed material does not
protrude into the crushing chamber..
Mechanical components may be damaged.
Cleaning
Do not clean the BB 51 under running water.
Using solvents is prohibited.
Lethal electric shock hazard!
Grease packings could be washed out.
Cleaning the crushing chamber
Operation of the BB 51 with the feed hopper removed
is not permissible.
Risk of crushing fingers and hands!
Replacing crusher jaws
Operation of the BB 51 with the feed hopper removed
is not permissible.
Risk of crushing fingers and hands!
