TA DHR-2 - Maintenance and Moving the Instrument

DHR Series Getting Started Guide Page 51
Maintenance and Repair
CAUTION: Adjustment, replacement of parts, maintenance and repair should be carried out by
trained and skilled TA personnel only. The instrument should be disconnected from the mains before
removal of the cover.
Moving the Instrument
Please follow these recommendations when you move or lift the instrument and its accessories:
• Always remove the temperature control module from the rheometer before attempting to move it.
Details on how to do this can be found in TRIOS Online Help.
• When moving the rheometer, the bearing clamp should always be in place, ensuring that the bearing
cannot be moved.
1 Ensure that the draw rod is installed.
2 Push the bearing clamp up onto the draw rod. Hold it in place and turn the knob at the top of the draw
rod in a clockwise direction to engage the bearing clamp. Continue to turn the draw rod until it is finger
tight.
CAUTION: Always hold the clamp and turn the knob, never the other way round.
MISE EN GARDE: Tenez toujours la bride de serrage et tournez le bouton, jamais dans l'autre sens.
3 Lifting the instrument should always be done with two people. With each person standing on either side
of the instrument, place hands in the locations shown below and lift upwards, keeping the instrument in
an upright position. See the figure on the next page.
WARNING: The cover should only be removed by authorized personnel. Once the
cover has been removed, live parts are accessible. Both live and neutral supplies
are fused and therefore a failure of a single fuse could still leave some parts live.
The instrument contains capacitors that may remain charged even after being dis-
connected from the supply.
AVERTISSEMENT: Seul le personnel autorisé doit retirer le couvercle. Une fois le
couvercle déposé, les pièces sous tension sont accessibles. Les alimentations
sous tension et neutres comportent des fusibles et par conséquent la défaillance
d'un seul fusible n'empêche pas d'autres pièces d'être encore sous tension.
L'instrument contient des condensateurs qui peuvent rester chargés même après
leur déconnexion de l'alimentation.
WARNING: Use two people to lift and/or carry the instrument. The instrument is
too heavy for one person to handle safely.
AVERTISSEMENT: Demandez à deux personnes de soulever et/ou de porter
l'instrument. L'instrument est trop lourd pour qu'une seule personne le manipule
en toute sécurité.
