MECHANICAL
INSPECTION
After
giving
the
machine
a
thorough
operating
test,
make
a
thorough
inspection
for
evidences
of
wear
and
other
conditions
which
may
cause
trouble
in
the
future.
Make
corrections
of
any
failures
discovered.
DO
NOT
change
any
adjust~
ment
without
good
cause.

Next, do what cleaning is necessary and lubri-
cate all bearings and bearing surfaces, being
careful not to use too much oil. On a well-ser-
viced
machine,
itis
not
necessary
to
lubricate
all points at every inspection; this can be deter-
mined by inspection. The motor needs very little
oil, only one drop of light oi] in each oil cup every
six to eight months. The motor is equipped with
LEDALOYL Bearings. These bearings are po-
rous and retain oilfor a long period of time and,
for this reason, the oil holeis not drilled through
the bearing. Excess oil on the motor bearings
tends
to
foul
the
Governor
and
Commutator
Brushes and is one cause of sticking brushes,
Clean Covers, Key Tops and Dials thoroughly,
Leave the machine not only working efficiently
but looking in first-class condition. This is a
mark of good workmanship and is the principal
item of Maintenance Service, which impresses
the customer. The inside of the machinehe can-
not see; therefore he must judge your proficien-
cy as a service man by what he can see on the
outside. This also increases the ''Silent Sales-
man'* value of the machines in your territory.
Clean
the
desk
or
working
space
used
while
mak-
ing the inspection.
This is avery
important
rule
of etiquette
for the Friden
Service
Man to follow.
Take
particular
care
to
protect
desks,
tables
or
other
working
space
used while
making
inspec-
tions or repairs.
The customer
appreciates
th
attentions
which
increase
your
reputation
for
good,
efficient
FRIDEN
SERVICE.
Fill
out
a
Service
Report
upon
completion
of
an
inspection
or repair
service,
noting
corrections
made,
if
any,
and
any
other
pertinent
informa-
tion
which
may
be
useful
for
invoicing
and
ma-
chine
record.
Make a separate
Service
Report
for
each
machine
worked
on,
have
some
per-
son in authority
sign the Service
Report
for the
customer
and then sign them
yourself.
Make
sufficient
copies
of
the
Service
Report
so
one
copy may be leit with the customer
and copies
retained
for
the
office
and
service
file.
Service
Reports
are
an
important
record
for
reference
in
case
of
a
question
arising
regarding
service
on a machine.
