Broken thermometers and their spilled mercury can be sent back to the
manufacturer. UPS will accept these packages provided they are labeled and the
material is in a secure container. See Princo support vendor for address
information.
Pinch Points
Do not place weights in precarious positions where they can be bumped and fall
to the floor. For large weights (over 10 kg) the pneumatic lift system is
recommended. In using a pneumatic lift system for weights up to 21,600 gram,
the safety pin (spike) that goes through the weights must be used. When the
machine is in operation the lift system moves the weight downward quickly
creating an area where anything lying beneath could be crushed. Press the
UP
and
DN
keys only when the areas above and below the weight are clear.
Fumes from Materials
Plan for the unexpected when it comes to materials giving off hazardous vapors.
Many polymers (PVC, PVF etc.) are well known for giving off hazardous fumes
at elevated temperatures. An exhaust system that removes fumes from both the
die exit and near the top of the barrel is strongly recommended. Consideration
should also be given to additives that may degrade or decompose at elevated test
temperatures.
Pre-Run Check List
The following points should be addressed before running the instrument for the
first time:
120V power outlet properly grounded? (230 V Europe/Asia)
Indexer level and on a sturdy bench?
Protective oil wiped out of barrel?
Exhaust hood or snorkel working?
Arm protection, long sleeves or lab coat
Operator using high temp gloves?
Operator using safety glasses?
