REGIUS MODEL 190 Service Manual Ver.1.00 2004.11.01
2.1 Preparation for Disassembly
2.1.1 Precautions for Disassembly and Reassembly
Caution Be sure to observe the following precautions
whenever performing disassembly or reassembly
on this device. Note that failure to do so may lead
to personal injury or damage to equipment.
• In order to protect against electric shocks, always
confirm that the supply of power has been turned
off before starting disassembly or reassembly.
Please also turn off the REGIUS 190's circuit
breaker or the facility's breaker.
• If printed circuit boards are to be handled, be sure
to secure an earth strap to your wrist and to attach
the clip end to a grounded section of the device.
• An earth strap must be worn to protect circuits
from damage.
• During reassembly, be sure to return wire bundles
to their original condition and to confirm that they
have not become trapped between, or caught on
components.
• Sensors are still electified even after the interlock
has been disengated. Be careful not to short-cir-
cuit the sensors.
Except for the work to replace the decelerating steel belt
unit ("2.5.3 Steel Belt Decelerating Unit, p.68"), no work is
necessary to touch the steel belt.
Danger Never touch the steel belt directly by hand. The hand or fingers may be cut due to the sharp
edge of the steel belt.
Caution If the fat of hand remains on the steel belt, rust may develop, and it may cause malfunction of
the subscan operation.
• Note for the anti-slip rubber on the justification assy
Do not touch the antislip rubber on the justification assy. Soiling
the rubber with finger fat may develop adhesion, and adversary
affects the separating process of cassette (especially mammo
cassette). Should the fat sits on the rubber, clean it with alco-
hol. However, note that the rubber has to be left untouched for
minimum of 2 days in the case an alcohol is applied. When the
new antislip rubber is available, replace it with a new one.
