on an
INSULATED OR WOODEN TABLE TOP.
This
will
preuent
any leakage
or shock hazards.
Your
Merc-O-Tronic Ignition
Analyzer
is
equipped
with either a
motor
or a vibrator.
The
motor
has oil
lite
bearings
and
should
be lubricated
with a
light
oil
once every
six
months.
Lubricate
cam wick at same
time.
(DO
NOT
OVER
LUBRICATE.
)
If replacement
of
breaker
point
is re-
quired,
order from
Merc-O-Tronic Instruments
Corporation as
this
is a
special breaker
assembly.
Breaker
points
are
to be
set
at
0.013.
Pres-
sure
not to
exceed
15 oz.
If vibrator
fails to operate check
and
make certain
that vibrator is in
socket.
When inserting vibrator,
make certain
pins
line
up
with
holes
in
socket.
NOTE: This
is a special
vibrator,
if replacement is
necessary
order
from
your
distributor or direct
from
factory.
