Develop Safe
Work
Habits
-
Unsafe actions are
identified as the cause of most accidents involving
the use of
tools
and machines. Be familiar with the
equipment and know how to use
it
safely. Use the
correct
tool
for the job and check its condition
before starting. Observe the warnings and cautions
in this manual and take special precautions when
working around electrical equipment.
Do
not work
alone if possible and do not take risks.
Be prepared
if
an accident does occur. Numerous
agencies such as the Red Cross and your local police
and fire departments offer basic courses in first aid,
mouth-to-mouth resuscitation, and fire control. Take
advantage
of
these offerings
so
you are ready to
respond when an accident happens. Learn
to
be safety
conscious and make safe practices a part of your work
routine.
Do
not work when tired or after consuming any
alcohol or drug that makes the operation of equipment
unsafe.
SET
REMOVAL
Some service procedures will require removing the
generator set from the coach. While there are many
variations, generator set installations are generally
classified as either conventional compartment mount
or
under-the-floor mount. In a compartment mount instal-
lation, a special compartment (see Figure
5-1)
is built
into the coach
to
house the generator set. The com-
partment is constructed with a vapor tight barrier that
seals
off
the generator set from the coach interior. The
generator set is usually fastened to the floor of the com-
partment which must be able to support the weight
of
the set. Access
to
the compartment is through a door
located in the exterior of the coach.
With the under-the-floor mount installation (see Figure
5-2),
special brackets are used to suspend the genera-
tor
set under the floor
of
the vehicle. The mounting
brackets bolt to special support members that are built
into the vehicle framework. The generator set is mounted
near the exterior
of
the vehicle. Access
is
provided
through a door located in the exterior of the vehicle.
Because of the wide variety
of
generator set installa-
tions,
it
is not possible to specify the exact removal
procedures for each generator set.
If,
after examining
the installation, a satisfactory method for removing the
set cannot be determined, contact the
RV
coach manu-
facturer to obtain their recommendations before
attempting
to
remove the set from the coach.
~WARN~NG
Generafor sets are heavy and can
m
result in severe personal injury if
dropped during removal.
Use
adequate lining devices
to
provide sufficienf support for the set. Keep hands
and feet clear while lining.
Special fuel handling procedures are required when
removing an LP gas (propane) powered set. The fuel
system must be purged of
LP
gas before the set can be
safely removed from the coach. Follow the purging
procedure before attempting to remove an LP gas
powered set
If
the generator set is powered bygasoline,
proceed to the appropriate set removal section.
AWARN~NG
LP-Gas (Propane) is exfremely flam-
m
mable and poisonous, and can result
in severe personal injury or deafh
if
accidentally
ignited or inhaled. Eliminate all possible sources of
ignition such as open flame, sparks, pilot lights,
cigarettes, and arc-producing machinery
or
switches
before purging LP-gas from the fuel system. Provide
adequate uenfilafion to dissipate LP-gas as
it
is
released. (Propane gas will sink to the ground and is
not easi/y detected.)
