7.4 Removing sample material after grinding
CAUTION
C10.0005
Burns
Heating of the sample material during grinding
−
Hot surfaces on the collecting receptacle or the grinding chamber can
cause burns.
−
Hot sample material in the collecting receptacle can cause burns.
•
Allow the hot sample material to cool down before removing the
collecting receptacle and opening the door.
•
Wear protective gloves.
CAUTION
C11.0010
Heavy collecting receptacle
Depending on the density of the sample material or the filling level, the filled
collecting receptacle may be very heavy.
−
Due to its weight, a filled collecting receptacle can cause personal injuries
when lifted out from the base frame.
•
As a general rule, always use both hands to pull the collecting
receptacle out of the base frame.
•
Two people should always remove a heavy collecting receptacle
from the base frame.
•
Wear safety shoes.
NOTICE
N18.0004
Damage to mechanical components
Jaw blockage with the motor shutting down
−
Due to the size and geometry of the grinding chamber, blockages may
occur when feeding a large quantity of big pieces of firmer sample
material. If the machine is not switched off in time in the event of
blockages, a motor protection switch turns the overloaded drive motor off.
•
Switch the machine off immediately when there is a blockage and
remove the sample material causing the blockage.
•
Reduce the feed of sample material to the feed hopper.
•
Fill larger and firmer sample material slowly and gradually into the
feed hopper.
•
If necessary, pre-grind larger and firmer sample material using a
larger gap width.
