Safety

Precautions

Before

operating

the

generator

set,

read

the

Operator's

Manual

and

become

familiar

with

it

and

the

equipment.

Safe

and

efficient

operation

can

be

achieved

only

if

the

unit

is

properly

operated

and

maintained.

Many

accidents

are

caused

by

failure

to

follow

fundamental

rules

and

precautions.

The

following

symbols,

found

throughout

this

manual,

alert

you

to

potentially

dangerous

conditions

to

the

operator,

service

per¬

sonnel,

or

tne

equipment.

caution]

This

symbol

refers

to

a

hazard

or

unsafe

practice

which

can

result

in

personal

injury

or

prod¬

uct

or

property

damage

.

FUEL

AND

FUMES

ARE

FLAMMABLE.

Fire,

explosion,

and

personal

injury

can

result

from

improper

practices.

•

DO

NOT

fill

fuel

tanks

while

engine

is

running.

Fuel

contact

with

hot

engine

or

exhaust

is

a

potential

fire

hazard.

•

DO

NOT

SMOKE

OR

USE

AN

OPEN

FLAME

near

the

gen¬

erator

set

or

fuel

tank.

•

Fuel

lines

must

be

adequately

secured

and

free

of

leaks.

Fuel

connection

at

the

engine

should

be

made

with

an

ap¬

proved

flexible,

non-conductive

line.

Do

not

use

copper

pip¬

ing

on

flexible

lines

as

copper

will

work

harden

and

Become

brittle.

•

Be

sure

all

fuel

supplies

have

a

positive

shutoff

valve.

GASOLINE

AND

LPG

FUEL

MAY

BE

ACCIDENTALLY

IG¬

NITED

BY

ELECTRICAL

SPARKS,

presenting

the

hazard

of

fire

or

explosion,

which

can

result

in

severe

personal

in¬

jury

or

death.

When

installing

the

generator

set:

•

Do

not

tie

electrical

wiring

to

fuel

lines.

•

Do

not

run

electrical

lines

and

fuel

lines

through

the

same

compartment

openings.

•

Keep

electrical

and

fuel

lines

as

far

apart

as

possible.

•

Place

a

physical

barrier

between

fuel

lines

and

electrical

lines

wherever

possible.

•

If

electrical

and

fuel

lines

must

pass

through

the

same

com¬

partment

opening,

make

certain

that

they

are

physically

separated

by

running

them

through

individual

channels,

or

by

passing

each

line

through

a

separate

piece

of

tubing.

•

DO

NOT

SMOKE

while

servicing

batteries.

Lead

acid

bat¬

teries

emit

a

highly

explosive

hydrogen

gas

that

can

be

ig¬

nited

by

electrical

arcing

or

by

smoking.

EXHAUST

GASES

ARE

DEADLY

♦

Never

sleep

in

the

vehicle

with

the

generator

set

running

un¬

less

vehicle

is

equipped

with

an

operating

carbon

monoxide

detector.

♦

Provide

an

adequate

exhaust

system

to

properly

expel

dis¬

charged

gases.

Inspect

exhaust

system

daily

for

leaks

per

the

maintenance

schedule.

Ensure

that

exhaust

manifolds

are

secure

and

not

warped.

Do

not

use

exhaust

gases

to

heat

a

compartment.

♦

Be

sure

the

unit

is

well

ventilated.

MOVING

PARTS

CAN

CAUSE

SEVERE

PERSONAL

IN¬

JURY

OR

DEATH

•

Before

starting

work

on

the

generator

set,

disconnect

batter¬

ies.

This

will

prevent

accidental

arcing.

•

Keep

your

hands

away

from

moving

parts.

•

Make

sure

that

fasteners

on

the

generator

set

are

secure.

Tighten

supports

and

clamps,

keep

guards

in

position

over

fans,

drive

belts,

etc.

•

Do

not

wear

loose

clothing

or

jewelry

while

working

on

gen¬

erator

sets.

Loose

clothing

and

jewelry

can

become

caught

in

moving

parts.

Jewelry

can

short

out

electrical

contacts

and

cause

shock

or

burning.

•

If

adjustment

must

be

made

while

the

unit

is

running,

use

ex¬

treme

caution

around

hot

manifolds,

moving

parts,

etc.

ELECTRICAL

SHOCK

CAN

CAUSE

SEVERE

PERSONAL

INJURY

OR

DEATH

•

Disconnect

starting

battery

before

removing

protective

shields

or

touching

electrical

equipment.

Use

rubber

insuia-

tive

mats

placed

on

dry

wood

platforms

over

floors

that

are

metal

or

concrete

when

around

electrical

equipment.

Do

not

wear

damp

clothing

(particularly

wet

shoes)

or

allow

skin

sur¬

faces

to

be

damp

when

handling

electrical

equipment.

•

Use

extreme

caution

when

working

on

electrical

compo¬

nents.

High

voltages

can

cause

injury

or

death.

•

Follow

all

state

and

local

electrical

codes.

Have

all

electrical

installations

performed

by

a

qualified

licensed

electrician.

Tag

open

switches

to

avoid

accidental

closure.

•

DO

NOT

CONNECT

GENERATOR

SET

DIRECTLY

TO

ANY

BUILDING

ELECTRICAL

SYSTEM.

Hazardous

volt¬

ages

can

flow

from

the

generator

set

into

the

utility

line.

This

creates

a

potential

for

electrocution

or

property

damage.

Connect

only

through

an

approved

device

and

after

building

main

switch

is

open.

Consult

an

electrician

in

regard

to

emergency

power

use.

GENERAL

SAFETY

PRECAUTIONS

•

Have

a

fire

extinguisher

nearby.

Maintain

extinguisher

prop¬

erly

and

become

familiar

with

its

use.

Extinguishers

rated

ABC

by

the

NFPA

are

appropriate

for

all

applications.

Con¬

sult

the

local

fire

department

for

the

correct

type

of

extin¬

guisher

for

various

applications.

•

Hot

coolants

under

pressure

can

cause

severe

personal

in¬

jury.

DO

NOT

open

a

radiator

pressure

cap

while

the

engine

is

running.

Stop

the

engine

and

carefully

bleed

the

system

pressure.

•

Benzene

and

lead,

found

in

some

gasoline,

have

been

iden¬

tified

by

some

state

and

federal

agencies

as

causing

cancer

or

reproductive

toxicity.

When

checking,

draining

or

adding

gasoline,

take

care

not

to

ingest,

breathe

the

fumes,

or

con¬

tact

gasoline.

•

Used

engine

oils

have

been

identified

by

some

state

or

fed¬

eral

agencies

as

causing

cancer

or

reproductive

toxicity.

When

checking

or

changing

engine

oil,

take

care

not

to

in¬

gest,

breathe

the

fumes,

or

contact

used

oil.

•

Remove

all

unnecessary

grease

and

oil

from

the

unit.

Accu¬

mulated

grease

and

oil

can

cause

overheating

and

engine

damage,

which

presents

a

potential

fire

hazard.

•

DO

NOT

store

anything

in

the

generator

compartment

such

as

oil

or

gas

cans,

oily

rags,

chains,

wooden

blocks,

portable

propane

cylinders,

etc.

A

fire

could

result

or

the

generator

set

operation*

(cooling,

noise

and

vibration)

may

be

ad¬

versely

affected.

Keep

the

compartment

floor

clean

and

dry.

•

Do

not

work

on

this

equipment

when

mentally

or

physically

fatigued,

or

after

consuming

any

alcohol

or

drug

that

makes

the

operation

of

equipment

unsafe.

INSTALLATION

CHECKS

INSTALLATION

Nearly

all

are

installed

by

the

motor

home

manufacturer.

Although

the

manufacturer

must

follow

safety

codes

when

install¬

ing,

certain

installation

problems

could

arise

after

the

unit

is

installed

and

subjected

to

vibration.

There

are

a

few

areas

that

you

as

the

operator

should

be

concern¬

ed

with.

If

in

doubt

about

any

aspect

of

your

generator

set’s

operation

or

safety,

contact

your

nearest

authorized

Onan

Service

Center.

A

daily

inspection

of

your

installation

should

include

the

following:

EXHAUST

Check

for

leaks

around

manifolds,

gaskets,

and

Make

sure

exhaust

are

not

heating

surrounding

areas

excessively.

If

so,

have

corrected

immediately.

Remember

VENTILATION

The

is

excessive

are

not

plugged

with

dust,

bugs,

leaves

or

anything

that

could

Don’t

use

for

compart¬

ment

heating

since

it

could

contain

poisonous

exhaust

gases.

Do

not

terminate

is

poisonous.

Direct

APPLYING

LOAD

If

to

warm

up

before

connecting

a

heavy

load.

Continuous

generator

overloading

may

cause

high

temperatures

that

windings.

Keep

the

load

within

nameplate

rating.
