MAINTENANCE
&
LUBRICATION
Clean the machine at the end
of
the day's work. Wipe
dust and other foreign matter
off
the Feed Dog teeth
Looper and Throat Plate evelets where they are easily
gathered.
Care should be taken to keep the machine free from rust,
especially when to leave it unused for some time.
Recommended lubricants are Shell X-100, Motor. Oil
lOW/30, Shell Vitria Oil 31 or the equivalent. For
operation and maintenance
of
the lubricator, refer to
Section
7.
Important
I
When adjusting
the
machine
or
replacing parts, always
disconnect
the
Electric Cord
from
the
power
source.
This
is
important
in
view
of
safety
to
the
operator
and
adjuster.

LUBRICATOR
1.
Operation
The lubricator comprises a
pump
and a reservoir. The
reservoir holds max 45 cc
of
oil. (Effective oil volume
is 28 cc.)
To operate
the
lubricator:
1. First unscrew
the
reservoir cap
by
half
a
turn.
*
2. Push the button to its lowest position (stroke: 12mm).
3. When released,
the
button
will automatically return
to its original position.
4. Lastly, tighten the cap to prevent oil leak during
operation.
*
Repeated
working
on
the
button
without
first
loosening
the
cap
may
produce
negative
pressure
in
the
reservoir,
and
the
dust
in
the
atmosphere
may
be
easily
introduced
in it
when
the
cap
is
loosened.
2.
Maintenance
1. Keep
off
dust or foreign matter when to fill oil (They
may cause jamming
of
the piston arid the check valve).
2. Rate of discharge is fixed and not adjustable (0.08 cc
per push).
3. At high temperatures, grease may run along points .
This is normal, grease being used when the lubricator
was assembled in our plant.
4. Reservoir is made
of
high density polyethylene. Keep
off
fire and refrain from using organic, benzene, or
xylene chemicals for cleaning.
Check periodically for correct working of the pump.
(Repeat oil feed and look at the oil through the
discharge pipe.)
