Safety
information
Note:
The
service
procedures
are
designed
to
help
you
isolate
problems.
They
are
written
with
the
assumption
that
you
have
model-specific
training
on
all
computers,
or
that
you
are
familiar
with
the
computers,
functions,
terminology,
and
service
information
provided
in
this
manual.
The
following
section
contains
the
safety
information
that
you
need
to
be
familiar
with
before
servicing
an
IBM
computer.
General
safety
Follow
these
rules
to
ensure
general
safety:
v
Observe
good
housekeeping
in
the
area
of
the
machines
during
and
after
maintenance.
v
When
lifting
any
heavy
object:
1.
Ensure
you
can
stand
safely
without
slipping.
2.
Distribute
the
weight
of
the
object
equally
between
your
feet.
3.
Use
a
slow
lifting
force.
Never
move
suddenly
or
twist
when
you
attempt
to
lift.
4.
Lift
by
standing
or
by
pushing
up
with
your
leg
muscles;
this
action
removes
the
strain
from
the
muscles
in
your
back.
Do
not
attempt
to
lift
any
objects
that
weigh
more
than
16
kg
(35
lb)
or
objects
that
you
think
are
too
heavy
for
you.
v
Do
not
perform
any
action
that
causes
hazards
to
the
customer,
or
that
makes
the
equipment
unsafe.
v
Before
you
start
the
machine,
ensure
that
other
service
representatives
and
the
customer’s
personnel
are
not
in
a
hazardous
position.
v
Place
removed
covers
and
other
parts
in
a
safe
place,
away
from
all
personnel,
while
you
are
servicing
the
machine.
v
Keep
your
tool
case
away
from
walk
areas
so
that
other
people
will
not
trip
over
it.
v
Do
not
wear
loose
clothing
that
can
be
trapped
in
the
moving
parts
of
a
machine.
Ensure
that
your
sleeves
are
fastened
or
rolled
up
above
your
elbows.
If
your
hair
is
long,
fasten
it.
v
Insert
the
ends
of
your
necktie
or
scarf
inside
clothing
or
fasten
it
with
a
nonconductive
clip,
approximately
8
centimeters
(3
inches)
from
the
end.
v
Do
not
wear
jewelry,
chains,
metal-frame
eyeglasses,
or
metal
fasteners
for
your
clothing.
Remember:
Metal
objects
are
good
electrical
conductors.
v
Wear
safety
glasses
when
you
are:
hammering,
drilling
soldering,
cutting
wire,
attaching
springs,
using
solvents,
or

any
other
conditions
that
might
be
hazardous
to
your
eyes.

reinstall
all
safety
shields,
guards,
labels,
and
ground
wires.

any
safety
device
that
is
