IT
CONVENIENT FOR
YOU
IN
THE FWIXJRE,
AS THIS INFORMATION MUST BE
GIVEN
WHEN
ORDERING
PARTS.

FOREWORD
Every
effort has
been
made
to
make
this
manual
as
complete
as
possible
so
that it will
provide
maximum
assistance in
operating
and
maintaining
your
LECO
Cold
A6rosol
Fog
Generator.
This
manual is
divided
generally into
two
sections Operating
and
Maintenance
Section
and
Illustrated
Parts
Section.
The
Operating
and
Maintenance
Section
contains
complete
instructions
for
operating
and
maintaining
your
LECO
Cold
Aerosol
Fog Generator.
No
difficulty
should
be
encountered
in
following
them.
Before
attempting
to start
your
unit
the first
time,
study the
complete Operating
Instructions
carefully
and
identify
all
parts
referred
to.
You
will find
that
the
operation
of
your
LECO
Cold
Aerosol
Fog
Generator
is
a
simple
matter
of
calibrating
the
flow
rate
and
operating
the
control
valve.
However,
like
all
mechanical
equipment,
your
unit
requires
a
certain
amount
of
maintenance.
The
Maintenance
Instructions
will
enable
your
LECO
Cold
Aerosol
Fog
Generator
to
give
you
continuous
and
trouble-free
service.
It
is
highly
recommended
that
some
system
be
established
to
assure
the
performance
of this
maintenance
as
its
importance
cannot
be
over-emphasized.
The
Illustrated
Parts Section
of
the
manual
is
made
up
of
exploded
views
and
parts
lists.
Every
part
of
the
unit
is illustrated
and
identified
with
a
part
.number.
Always
order
parts
by
part
number,
description
and
the
serial
number
of
your
unit.
Although,
with
proper
maintenance,
your
unit
should
operate
indefinitely
without
any
trouble,
there
might
come
a
time
when
trouble
does
develop.
For
such
an
occasion,
a
complete
Trouble
Shooting
section
has
been
prepared
and
included
in
this
manual.

SCOPE
This manual
provides
the
description,
theory
of
operation,
operating
instructions,
calibrating
instructions,
maintenance
instructions and
illustrated
parts
breakdown
for the
LECO
P-1
Aerosol
Generator.
DESCRIPTION
The
LECO
P-1
Aerosol
Generator
is
designed
for indoor and
outdoor
use.
It consists
of
a
centrifugal
blower
driven
by
a
2-cycle
gasoline
engine,
a
discharge
head,
an
insecticide
tank
and
insecticide
flow control
valve with four
adjustable
flow
rate
settings.
The
Generator
is
a
complete hand held
unit
weighing
only
17 pounds.
See
Figure
1.
THEORY
OF
OPERATION
The
LECO
P-1
Generator
is
designed
for dispersing
insecticides
at
an
Ultra
Low
Volume
(ULV)
rate
with
droplets
of
optimum
size. The
insecticide
is
forced
from the
tank
through
the
system
by
air
pressure
obtained from
the
blower.
The insecticide
flows
from
the
tank
through
the adjustable control
valve
to
the
specially
designed
LECO
dispersing
head where
it is
sheared
into
optimum
size droplets,
by
the air blast from the
blower and
is
dispersed into the
atmosphere.
After
dispersal
the
droplets
stay
suspended
in the
air
and
penetrate
the
insect
infested
areas.
