2 Special safety instructions when working in the
vicinity of powerful magnetic fields
RISK TO HEART PACE-MAKER WEARERS 2
The permanent magnets of they axis have an extremely powerful magnetic field. Personnel wear-
ing heart pace-makers are NOT permitted to stand in the vicinity of permanent magnets (see
item1and2inFig.2-1). 2
CAUTION POWERFUL MAGNETIC FIELD 2
à Do not wear watches in the vicinity of permanent magnets since they can be damaged.
à Do not bring magnetic data media, check or credit cards near permanent magnets - the data
on the data media may be erased by the magnetic field of the permanent magnets.
WARNING RISK OF CRUSHING 2
Do not approach permanent magnets when carrying metal objects made of iron, steel or nickel.
The powerful force of attraction may cause fingers to be crushed. 2
