CAUTION
C9.0045
Damage to hearing
A high noise level may arise depending on the type of the material, the jaws
used and the duration of grinding
−
Excessive noise in terms of level and duration can cause impairments or
lasting damage to hearing.
•
Suitable sound insulation measures must be provided or hearing
protection worn.
NOTICE
N17.0003
Damage to mechanical components
Overfilling the feed hopper and the grinding chamber
−
Feeding too much sample material can result in increased wear to the
jaws and wearing plates and to blockages.
•
Do not use the feed hopper for storing sample material.
•
Do not fill the grinding chamber to over 65% full.
•
Do not exceed the specified maximum feed size for the sample
material.
•
Fill larger and firmer sample material slowly and gradually into the
feed hopper.
•
Pre-grind larger and firmer sample material with a larger gap where
necessary.
NOTICE
Filling the crushing chamber to more than 2/3 full may damage the guide plates on the
feed hopper (A) and will result in sample material being conveyed by the activated crusher arm
into the crusher housing behind the crusher arm.
The fill volume also influences the fine share in the pre-ground sample. The fuller the crushing
chamber, the higher the fine share may be.
NOTICE
With respect to the fill level, attention should also always be paid to the volume of the
collecting receptacle (D). The fill quantity must not exceed the volume of the collecting
receptacle (D).
NOTICE
Only fill the feed hopper (A) and the crushing chamber when the machine is in operation.
The feed hopper (A) is not intended for storing sample material, rather its sole purpose is for
feeding the material into the crushing chamber. It furthermore prevents inadvertent access to the
crushing chamber and holds back any splashing sample material.
