TROUBLESHOOTING
AND MAINTENANCE
5.1 Electrical
acc
id
ents
and
the remedy
5.1.1 The main motor does not start
if
lh
e pilot lamp on the panel is not light. A certain
sound from the contactor can be heard when the
ma
chine
is
started. The starting
is
OK
when the
green pilot lamp above the governor is light. Otherwise, check
if
there is any lack
of
phase or
anything wrong with connection. Restart after remedy.
5.1.2 If the machine is overloaded
or
any part is blocked
in
the course
of
operation, the pilot
lamp (green)
on
the panel will flash continuously. C
ut
the motor
off
and remedy the trouble.
Then restart the machine.
5.1.3
If
the pilot lamp for the motor starting flashes, open the electric box below to check
if
the 2A and I0A cartridge fuses are blown out.
If
so, replace them.
If
the pilot lamp remains
flashing after restarting, a30V Gratz rectifierwith the type S8154 is required.
Caution! Connection must be
cor
rect and
the
earth
wire
is in good
co
ndition.
5.2 Maintenance
5.2.1 The machine parts
are
lubricated
by
a timing automatic lubricating device. The electric
lubricator on the right side
of
the machine feed the lubricating oil to the dislributing plant
on
the
upside
of
machine. The distributiJ1g pl
ant
feed the oil to the dilforent machine parts by
th
e
copper tubing that connected with the distributing plant.
The oil feeding frequency and the duration
of
the feeding can
be
set
by
the electric lubricator
(Fig
16
).
The quantity
of
the o
il
that
is
feed to the different machine parts passing the copper
tubing can
be
set separately by the adjusting screw on the distributing plant.(Fig 17) Viscosity
