Develop Safe Work Habits - Unsafe actions are
identified as the cause of most accidents involv-
ing the use of tools and machines. Be familiar
with theequipment 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 pre-
cautions when working around electrical equip-
ment. Don’t work alone if possible and don’t 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.
GENERATOR SET REMOVAL
Someservice procedures will require that the genera-
tor set be removed from the coach. While there are
many variations, generator set installations are
generally classified as either conventional compart-
ment mount or under floor mount. In a conventional
compartment mount installation, a special compart-
ment (see Figure
5-1) is built into the coach to house
the generator set. The compartment is constructed
with a vapor tight barrier that seals off the generator
set from the coach interior. The generator set is usu-
ally fastened to the floor of the compartment 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.
5-2
In an under floor mount installation (see Figure 5-2),
a special housing is used to suspend the generator
set from the underside of the coach. The housing
bolts to special support members that are built into
the coach framework. The housing is mounted near
the exterior of the coach and limited access is pro-
vided through a door located in the exterior of the
coach.
Because of the wide variety of generator set installa-
tions, it is not possible to specify the exact removal
proceduresfor each generator set. If, after examining
the installation, a satisfactory method for removing
the set cannot be determined, contact the RV coach
manufacturer to obtain their recommendations
before attempting to remove the set from the coach.
Generator sets are heavy and can
-1 cause personal injury if dropped
during removal.
Use adequate lifting devices fo pro-
vide sufficient support for fhe set. Keep hands and
feef clear while lifthg.
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 purg-
ing procedure described in the next section before
attempting to remove an LP gas powered set. If the
generator set is powered by gasoline, proceed to the
appropriate set removal section.
LP-Gas (Propane) Purging Procedure
To purge the LP gas from the set fuel system, close
