SECTION

SAFETY
1-1.
GENERAL
Before
using
this
trailer,
several
matters
should
be
con
sidered
so
that
safe
arrival
of
equipment
at
the
work
site
is
not
left
to
chance.
Towing
any
mobile
unit
requires
awareness
of
the
situation
and
a
trailer
fully
prepared
and
connected.
When
towing,
it
takes
longer
to
start,
stop,
and
pass.
Also,
turning
and
backing
may
cause
unforseen
difficulties.
It
is
recommended
that
the
entire
subject
of
towing
be
given
considerable
thought
before
the
actual
operation
takes
place.
Additionally,
any
trailer
used
on
a
public
highway
is
sub
ject
to
all
state
and
federal
regulations
governing
trailer
usage.
Should
the
trailer
be
used
only
on
private
prop
erty,
it
may
not
be
necessalyto
comply
with
existing
leg
islation.
If
in
doubt,
check
state
and
federal
laws,
or
con
tact
the
local
law
enforcement
agency.
1-2.
WEIGHT
A
nameplate,
located
on
the
right
front
frame
member
(when
facing
hitch),
is
provided
on
this
trailer.
If
a
name
plate
is
not
present
or
has
been
defaced,
consult
the
Owners
Manual
for
weight
specifications.
This
name
plate
(or
Owners
Manual)
gives
the
maximum
weight-,
carrying
capacity
for
the
complete
trailer
and
for
each
axle
(GVWR
and
GAWR)
for
this
particular
trailer.
The.
designation
GVWR
means
Gross
Vehicle
Weight
Rat~
ing
and
is
the
maximum
the
trailer
can
weigh
with
the
en
gine
driven
generator
and
all
associated
equipment
(tools,
cables,
gas
cylinder,
etc.)
on
board.
The
designa
tion
GAWR
means
Gross
Axle
Weight
Rating
and
is
the
maximum
load-bearing
capacity
of
the
axle(s)
on
this
particular
trailer.
It
is
very
important
not
to
overload
the
trailer.
It
is
also
important
to
know
the
trailers
gross
weight.
The
gross
weight
may
be
determined
by
weigh
ing
the
trailer
at
a
local
material
or
fuel
yard.
Gross
trailer
weight
should
be
taken
into
consideration
when
select
ing
the
towing
vehicle.
Holes
are
provided
in
the
frame
of
the
trailer
for
mount
ing
an
engine
driven
generator.
AA
CAUTION:
UNCONTROLLED
TILTING
OF
TRAILER
can
result
In
personal
Injury
or
equIpment
damage.
Install
generator
onto
trailer
with
engine
end
toward
hitch
end
of
trailer.
Distribute
weight
so
that
trailer
tongue
weight
is
approximately
10%
of
the
gross
trailer
weight.
1-3.
TONGUE
WEIGHT
Tongue
weight
is
defined
as
the
amount
of
the
trailer
weight
that
actually
rests
on
the
hitch
of
the
towing
vehi
cle.
Recognized
standards
recommend
that
the
tongue
weight
of
this
trailer
be
approximately
10%
of
the
gross
trailer
weight.
It
is
important
to
maintain
this
tongue
weight.
See
Table
1-1
for
specific
information
on
tongue
weights.
The
tongue
weight
can
often
be
adjusted
by
re
locating
some
of

Gross
Trailer
Weight.
Tongue
weight
can
be
determined
by
weighing
the
tongue
on
a
scale
of
adequate
capacity.
For
best
accu
racy,
be
sure
that
the
trailer
is
level
when
taking
the
scale
reading.
The
proper
tongue
weight
and
appropriate
vehicle
speed
(never
above
45mph
or72
km/h).will
help
consid
erably
in
preventing
the
condition
known
as
fishtailing.
Fishtailing
is
a
swaying
motion
in
the
trailer
which
can
become
so
pronounced
that
the
trailer
and
towing
vehi
cle
may
be
physically
flipped
over.
Regardless
of
the
de
gree,
fishtailing
is
always
potentially
dangerous
be
cause
of
the
loss
of
directional
stability.
Afthough
tongue
weight
and
speed
considerations
are
prime
factors
in
fishtailing,
other
areas
such
as
poor
weight
distribution,
improper
wheel
alignment,
dam
aged
suspension
components,
and
the
like,
should
not
be
overlooked.
1-4.
HITCHES
The
appropriate
hitch,
properly
installed
to
the
towing
vehicle,
is
vitally
important
for
towing
safety
(see
Table
1-1
for
hitch
recommendations).
Statistics
gath
ered
from
accident
reports
show
that
in
one
out
of
every
five
automotive
accidents
invoMng
trailers
there
had
been
a
hitch
failure.
Therefore,
the
selection
and
instal
lation
of
the
hitch
should
be
a
matter
of
prime
concern.
1-5.
HITCH
LOCKING
DEVICE
(If
Applicable)
This
trailer
is
equipped
with
a
safety
pin
to
lock
the
hitch
in
place
after
coupling
to
the
towing
vehicle
ball
is
com
plete.
Always
be
sure
that
the
safety
pin
is
in
place
so
that
the
hitch
does
not
work
loose
and
cause
a
serious
and
expensive
accident.
1-6.
SAFETY
CHAINS
(Figure
1-1)
This
trailer
is
equipped
with
two
safety
chains.
Proper
connection
of
the
safety
chains
to
the
towing
vehicle
is
129
216
Page

essential
for
safe
operation.
The
safety
chains
should
be
crossed
under
the
tongue
of
the
trailer
(see
Figure
1-1)
forming
a
cradle
to
prevent
the
tongue
from
dropping
to
the
ground
should
a
failure
in
the
hitch
or
ball
occur.
Additionally,
only
enough
slack
should
be
al
lowed
in
the
chains
to
permit
unrestricted
turning
of
the
vehicles.
When
making
slack
adjustments,
be
sure
that
the
slack
in
each
chain
is
the
same
and
the
safety
chains
do
not
drag
on
the
road.
Always
attach
the
safety
chains
when
towing
this
trailer.
1-7.
BREAKAWAY
BRAKE
CHAIN
(If
Applicable)
The
trailer
breakaway
chain
is
provided
to
automatically
apply
the
trailer
brakes
should
the
trailer
separate
from
the
towing
vehicle.
It
Is
therefore
highly
important
to
con
nect
the
breakaway
chain
to
the
towing
vehicle
to
utilize
this
safety
feature.
When
connecting
the
breakaway
chain,
be
sure
that
the
chain
has
a
direct,
free
pull
to
the
towing
vehicle
and
is
not
wrapped
around
the
safety
chains,
tongue,
wiring,
or
any
other
components
in
any
manner.
1-8.
LIGHTS
This
trailer
is
equipped
with
proper
lighting
equipment
as
specified
in
the
U.S.A.
Federal
Motor
Vehicle
Safety
Standards
in
effect
at
the
time
of
manufacture.
The
trailer
lights
must
be
functioning
properly
at
all
times
for
safe
operation.
It
is
recommended
that
the
furnished
electrical
connector
be
properly
installed
(see
later
Sec
tion
in
this
manual)
to
the
towing
vehicle
so
that
correct
lighting
operation
is
achieved.
Although
connectors
may
be
physically
the
same,
they
may
be
electrically
differ
ent.
Always
be
sure
that
the
towing
vehicle
connector
and
trailer
plug
mate
properly
(both
physically
and
elec~
trically),
and
that
all
trailer
lights
function
correctly.
1-9.
TIRES
Be
sure
that
the
tires
are
properly
inflated.
Check
pres
sure
every
30
days.
To
determine
the
correct
pressure,
see
the
manufacturers
recommendations
on
the
sidewall
of
the
tire.
It
is
also
important
to
annually
check
the
condition
of
the
valve
stems
by
bending
them
over
and
inspecting
for
cracks.
Do
not
neglect
the
tires.

Torquing
Procedure
Initially
tighten
to
12-20
ft.
lbs.
(16-27
N~m)
by
using
a
cross-tightening
sequence(1
,
3,
2,4
or
1,3,5,2,4).
Fin
ish
torquing
to
values
stated
in
text
(Section
1-10).
IMPORTANT:
Nuts
and
studs
should
be
clean,
dty,
and
unlubricated.
Retorque
after50
miles
(80km)
of
use
and
annually
thereafter.
It
is
very
important
that
the
wheel
nuts
are
properly
tight
ened.
The
wheel
manufacturer
recommends
that
the
wheel
nuts
on
the
four-lug
hubs
(12
in.
or
305
mm
tires)
be
torqued
to
approximately
60
ft.
lbs.
(81
Nm)
and
that
the
wheel
nuts
on
the
five-lug
hubs
(14
in.
or
356
mm
tires)
be
torqued.
to
approximately
70
ft.
lbs.
(95
N~m).
Annually,
or
more
often
depending
on
usage,
recheck
wheel
nuts
for
propertightness
(see
Figure
1-2).
When
tightening
the
wheel
nuts,
be
sure
that
the
proper
tight
ening
sequence
is
used.
Start
at
the
approximate
top
left,
and
always
move
directly
across
the
hub
so
that
even
tightness
is
assured.
Also,
annually
or
every
12,000
miles
(19,500
km)
whichever
comes
first,
check
wheel
bearings
for
proper
lubrication
and
adjustment
to
aid
long
life
and
safe
operation.
