GENERAL
Before
using
this
trailer,
several
matters
should
be
considered
so
that
safe
arrival
of
equipment
at
the
work
site
i~
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
unforeseen
difficulties,
It
is
recom
mended
that
the
entire
subject
of
towing
be
given
consider
able
thought
before
the
actual
operation
takes
place.
Additionally,
any
trailer
used
on
a
public
highway
is
subject
to
all
state
and
federal
regulations
governing
trailer
usage.
Should
the
trailer
be
used
only
on
private
property,
it
may
not
be
necessary
to
comply
with
existing
legislation.
If
in
doubt,
check
state
and
federal
laws
or
contact
the
local
law
enforcement
agency.
A
nameplate,
located
on
the
right
front
frame
member
(when
facing
hitch),
is
provided
on
this
trailer.
If
a
nameplate
is
not
present
or
has
been
defaced,
consult
the
Owners
Manual
for
weight
specifications.
This
nameplate
(or
Owners
Manual)
gives
the
maximum
weight-carrying
capacity
for
the
com
plete
trailer
and
for
each
axle
(GVWR
and
GAWR)
for
this
particular
trailer.
The
designation
GVWR
means
Gross
Vehicle
Weight
Rating
and
is
the
maximum
the
trailer
can
weigh
with
the
welding
generator
and
all
associated
equip
ment
(tools,
cables,
gas
cylinders,
etc.)
on
board.
The
designation
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
trailers
gross
weight.
The
gross
weight
may
be
determined
by
weighing
the
trailer
at
a
local
material
or
fuel
yard.
Gross
trailer
weight
should
be
taken
into
consideration
when
selecting
the
towing
vehicle.
Holes
are
provided
in
the
frame
of
the
trailer
for
mounting
a
welding
generator.
~ountingawajngilortothistrailer,
ensure
that
the
engine
end
is
mounted
toward
the
front
(hitch
end)
of
the
trailer.
Be
sure
to
orient
the
unit
in
such
a
fashion
that
proper
weight
distribution
and
tongue
weight
are
achieved.
1-3.
TONGUE
WEIGHT
Tongue
weight
is
defined
as
the
amount
of
the
trailer
weight
that
actually
rests
on
the
hitch
of
the
towing
vehicle.
Recognised
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
relocating
some
of
the
associated
equipment
on
the
trailer.

permission.
From
SAE
Handbook
(1974)
Tongue
weight
can
be
determined
by
weighing
the
tongue
on
a
scale
of
adequate
capacity.
For
best
accuracy,
ensure
that
the
trailer
is
level
when
taking
the
scale
reading.
The
proper
tongue
weight
and
appropriate
vehicle
speed
(never
above
45
mph)
will
help
considerably
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
vehicle
may
be
physically
flipped
over.
Regardless
of
the
degree,
fishtailing
is
always
potentially
dangerous
because
of
the
loss
of
directional
stability.
Although
tongue
weight
and
speed
considerations
are
prime
factors
in
fishtailing,
other
areas
such
as
poor
weight
distribution,
improper
wheel
alignment,
damaged
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
gathered
from
acci
dent
reports
show
that
in
one
Out
of
every
five
automotive
accidents
involving
trailers
there
had
been
a
hitch
failure.
Therefore,
the
selection
and
installation
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
complete.
Always
ensure
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
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.
Addition.
ally,
only
enough
slack
should
be
allowed
in
the
chains
to
permit
unrestricted
turning
of
the
vehicles.
When
making
slack
adjustments,
ensure
that
the
slack
in
each
chain
is
the
same
and
that
the
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
brake
chain
is
provided
to
automati
cally
apply
the
trailer
brakes
should
the
trailer
separate
from
the
towing
vehicle.
It
is
therefore
highly
important
to
connect
the
breakaway
chain
to
the
towing
vehicle
to
utilize
this
safety
feature.
When
connecting
the
breakaway
chain,
ensure
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
Stan
dards
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
Sections
in
this
manual)
to
the
towing
vehicle
so
that
correct
lighting
operation
is
achieved.

TIRES
Ensure
that
the
tires
are
properly
inflated.
To
determine
the
correct
pressure
see
the
manufacturers
recommendations
on
the
sidewall
of
the
tire.
It
is
also
important
to
periodically
check
the
condition
of
the
valve

by
bending
them
over
and
inspecting
for
cracks.
Do
not

5-HOLE
WHEELS
It
is
very
important
that
the
wheel
nuts
are
properly
tightened.
The
wheel
manufacturer
recommends
that
the
wheel
nuts
on
the
four-lug
hubs
(12
inch
tires)
be
torqued
to
approximately
60
foot.pounds,
and
that
the
wheel
nuts
on
the
five-lug
hubs
(14
inch
tires)
be
torqued
to
approximately
70
foot-pounds.
Periodically,
depending
on
usage,
recheck
wheel
nuts
for
proper
tightness
(see
Figure
1-2).
When
tightening
the
wheel
nuts,
ensure
that
the
proper
tightening
sequence
is
used.
Start
at
the
approximate
top
left
and
always
move
directly
across
the
hub
so
that
even
tightness
is
assured.
Additionally,
a
periodic
check
of
the
wheel
bearings
for
proper
lubrication
and
adjustment
will
aid
long
life
and
safe
operation.
