Chapter 14 Replacing Consumable Parts
The degree of control of the gap between the rotor and cylinder and
side plate is very severe on the CP IV-2, making it a higher quality
vacuum pump than on the previous machines. Since special
techniques and jigs are necessary when making adjustments, please
do not assemble or disassemble the pump. When changing the
vacuum pump, there are some general rules that should be
followed. If any of the problems in the table listed below occur,
and it is necessary to disassemble the pump, please contact Fuji.
Table 14-3 Causes and Measures
The
vacuum
pressure
is low.
Cause
Measure
Condition
Oil is in the filter and
the blade can not
project.
There is debris in the
filter and air cannot
be drawn in.
Remove the filter case, noise reduction
muffler and one-way valve. Wash the
inhalation and ventilation openings in a
chlorine based liquid such as chlorothene
or diaphron. Turn the fan (if the fan is not
turned, leave it in this state for a while). After
checking to see that the fan is working, turn
on the power sourch so that the oil and
cleaning liquid is spewed out.
When using the cleaning fluid, to ensure
that none of the volatile gases are inhaled,
make sure that there is sufficient
ventilation in the room. Also make sure
that none of the cleaning fluid makes
contact with alcohol, benzene, gasoline,
and cleaning oil are all very flammable
liquids, do not use them as the
cleaning solution.
Remove the filter element and the
compressed air will eliminated.
Using a neutral detergent such as
diaphron or chlorothene, wash the dirty parts.
After it is dry, place it back in again. Do not
use thinner, alcohol, benzene,
gasoline, or any other cleaning oils
on the parts that make contack with
the picking mechanisms.
