GM
COACH
OPERATION
TO
THE
OPBBATOB
Information
in
this manual is
written
directly
to
you-the
operator.
No
attempt
has been
made
to
teach driving skill,
rules
of
the
road,
or
highway safety practices. Such essential
phases
of
operating
a coach must be acquired by
the
operator
through
other
training facilities.
The
primary
purpose
of
this booklet
is
to acquaint the
operator
with
important
operating
features
of
this
GM
Coach.
A knowledge
of
such features
and
the practicing
of
recom-
mended procedures
in
this book will
add
to your skill
as
an
operator. In addition, such knowledge will
provide
passenger
comfort
and
safety.
Some
of
the items in this manual may
or
may
not
be
the
responsibility
of
the
operator,
depending
upon
regulations
of
the
operating
company. Regardless
of
responsibility, the oper-
ator should know the contents
of
this manual
to
obtain the
best
operating
efficiency.
OPBBATOB'S
CONTBOLS
Controls, gauges,
and
switches used to normally operate
and
drive the coach are located in
the
area generally known
as
the
"operator's
compartment"
as
illustrated on opposite page.
All controls necessary for
the
normal driving
of
coach,
and
for passenger comfort
and
safety are readily accessible
to
the
operator.
Switches, gauges,
and
tell-tale lights are
grouped
on the
gauge
and
switch panel in
front
of
the driver
and
on panel at
left
of
driver
(page
4).
This
coach is
equipped
with
gauges, tell-tale lights, and
warning
devices which
warn
of
abnormal
operating
conditions.
The
margin
of
safety in these instruments is
enough
to
warn
the
operator
of
trouble
before any serious damage happens.
Get
the
"INSTRUMENT
BOARD
HABIT"-It's
a
good
practice.
Instructions on the most commonly used special equipment
are included in this manual.
The
operator
can,
upon
inspection
of
his coach, determine specific instructions to use.

The
GM
Diesel engine is an effective brake in checking vehi-
cle speed when going down grades. Braking effect
of
the engine
increases with its speed; however, the maximum speed must
not exceed :2000 rpm. Engine, running at governed speed, will
safely hold vehicle going down a grade in the same gear re-
quired to go
up
the grade.
When
descending grades with the accelerator in released
position, the governor will automatically shut off fuel supply
to the injectors. This will allow engine to attain maximum
braking effort

If
engine starts within the
10
to
15
second period and stops
as
soon
as
button
is
released, failure may be due·
to
heat
build-up in engine.
The
engine can be made to
run
by holding in the starter button which then
overrides the high water temperature control cutout switch. Running
the
engine for 30 to
45
seconds will usually circulate sufficient water through
the radiator to reduce engine temperature
to
normal.

not
light, the tell-tale bulb has burned out, excessively high
or
low refrig-
erant pressure exists,
or
an
open circuit exists. Place
"IGNITION

in
"OFF"
position ("MASTER
SWITCH"
in
"OFF"
position).

OPERATION
BLBCTBICAL
SYSTEM
CIRCUIT
BBBAKBBS
All circuits in the electrical system are protected
by
circuit
breakers, all
of
which are automatic reset type except the charg-
ing system master circuit breaker. There are no fuses in the
system.
The
circuit breakers are located in the circuit breaker
panel to left
of
driver, and in the regulator compartment.
Whenever a short exists in a
circuit protected
by
an automatic
reset type circuit breaker, action
of
the circuit breaker opens the
circuit, causing protected lights
to
go
out
or
the system to cease
functioning.
After
the
circuit
breaker element cools, the cir-
cuit will again be closed.
As
long
as
the short exists, action
of
cir-
cuit breaker will intermittently .
open and close the circuit pro•
tected.
If
it
is
determined
that
a short
exists in a circuit by the action
of
a circuit breaker, switch should
be turned off to the circuit if pos-
sible, and immediate measures
be taken to correct the shorted
condition.
If
the charging system master
circuit breaker
(in
regulator com-
partment) breaks the charging
circuit, the generator indicator
pointer will go
to
right segment
marked
"NOT
CHARGING"
(page 22).
The
circuit breaker,
which
is
manual reset, should
not
be reset until cause
of
short
is
determined and corrected.
ANTI-FBBBZB
Engine cooling system should be protected with anti-freeze
solutions for temperatures below
32°F.
Only ethylene-glycol
type solutions should be used.
