TRACKING - Fig. 9.
Every
saw
has
slightly
different
running
characteristics
on a
band
saw
machine
due to the condition of the
steel
ribbon
it
is
made
from,
the
brazed
joint
and
the
tension
in the
blade
ribbon.
This
is
compensated
by
using a crowned
(O,r
slightly
curved)
rubber
on the
wheels
and
prov-
•
iding the top wheel with a
slight
tilting movement.
We
call
this
track-
\
ing
and
by
slackening
the
lock
handle
and
adjusting
the
tracking
hand-
wheel,
it
is
possible
to
adjust
the
tilt
of the top wheel,
so
that the
saw
runs
steadily
in the
centre
of the wheel.
This
is
important
because
the
blade
then
passes
in a
straight
line
between the top and bottom
wheel, and does not snake. When the
latter
occurs
the
back
of the
saw,
keeps
hitting the guide
plate
and
woodwork and damaged guides
result.
Do
not
forget
to
re-tighten
the
tracking
lock
bolt
after
adjusting.
SAW
PULLEYS
A
brush
as
shown
in
Fig. 10
is
provided
on the
bottom
pulley to
remove
sawdust,
whilst
the
rubber
on the top
pulley
should be cleaneq daily to
prevent
accumulation
of
sawdust
which would
cause
the
blades
to
run
out
of
true
line.
.
The
saw
pulleys
must
be
kept
in
accurate
balance
to avoid
vibration.
It
is
essential
that
the
rubbers
on the
faces
of the
pulleys
are
kept
at
an
even
thickness
by
truing
up
occasionally
or
if
they
are
badly
worn
should
be
replaced
by new
ones.
If
the
machine
is
used
with badly
worn
pulleys
the
saw
will
vibrate,
resulting
in
bad
sawing and
broken
saws.
We
have a
service
arrangement
which we
recommend
whereby newly
rubbered
pulleys
can
be
supplied
against
the
return
of the
existing
pulleys,
an
appropriate
charge
being
made
to
cover
re-rubbering
only.
Where
it
is
not pra.ctical
for
the
customer
to
use
our
exchange
service
of
vulcanised
wheels
it
is
possible
for
the
customer
to
carry
out
his
ownre-rubbering,
which,
whilst
not
so
good
as
the
vulcanised
process,
is
satisfactory
if
the
instructions
below
are
carefully
followed. Rubber
bands
and
fixing
solution
can
be
supplied to
order.

REMOVAL
OF
SAW
PULLEYS.
The top
and
bottom
pulleys
are
idelltical,
and
when taking
them
from
the
machine
for
re-rubber-
ing the
entire
wheel
comprising
plate
and
hub
should
be
removed.
To do
this
remove
the
spindle
nut
and
withdraw the
wheel
complete.
It
should
be
noted
that
for
both
pulleys
this
locknut
has
a
left
hand
thread.
FIXING INSTRUCTIONS FOR THE APPLICATION OF RUBBER
BANDS
TO
BAND
SAW
PULLEYS.
The
Croid
Glue
No.9
supplied
is
ready
for
use
and
should
be
applied
cold.
In cold
weather
and
if
the glue
is
solidified
warm
up to 800 Fahrenheit
to give fluidity
and
to
assist
spreading.
Thoroughly
scrape
and
clean
the
face
of the wheel
free
from
old
abrasive.
This
is
very
import-
ant.
Stretch
the
rubber
band
over
the wheel.
To
assist
with the
application
of the glue
it
will
be
found
more
convenient to
place
between
the
wheel
rim
and
the
rubber a piece
of wood
approximately
lin
diameter.
Apply the glue
across
the
face
of the
wheel
and
turn
the wood
round
the
rim
thereby
exposing a
section
of the
rim
to
be
glued.
Proceed
until
the whole of the wheel
has
been
covered
taking
care
to
glu"e
the whole
face
in
order
to
obtain
adhesion
over
the whole width to
prevent
the
edges
of
the
band
lifting.
Tightly
apply a
piece
of
tape
of the
same
width
as
the
wheel
around
the
circumference,
thereby
giving
as
much
pressure
as
possible
to the
rubber
band.
Leave
at
least
24
hours
before
use.
Finally
true
up the
rubber
and
put a slight
crown
on the
face.
This
is
done
by
revolving
the
wheel
and
holding
against
it
a wood
block
covered
with
emery
cloth,
preferably
when mounted
on the
machine.
Check wheel
for
balance
before
use.
FOR TROPICAL COUNTRIES a
Croid
Glue No. 10
is
supplied
with a
hardening
powder
which
must
be
added
in
the
proportion
of one
part
of
hardener
to
56
parts
by
weight
of
glue
and
thoroughly mixed. The
remainder
of
the
procedure
for
cleaning
and
fixing
is
the
same
as
in
the
instructions
above.

ELECTRICAL
INSTALLATION
INSTRUCTIONS
The
cabling
between
the
motor
and
the
control
gear
has
been
carried
out
by
Wadkin
Ltd.,
and
it
is
only
necessary
to
bring
the
line
leads
to the
machine
for
it
to
be
put
into
service.
This
should
be
done
as
follows
:-
(1)
Fit
triple
pole
isolating
switch
near
the
machine,
unless
this
has
been
supplied
to
special
order
by Wadkin Ltd. , when
it
will
be
fitted
and
connected
up
at
the
machine.
(2) Connect the
line
lead
to the
appropriate
terminals,
see
diagram.
The
cables
should
be
taken
to the
machine
in
conduit
and
secured
to the
control
gear
by
means
of
locknuts.
(3) Connect
solidly
to
earth.
(4)
Close
isolating
switch
and
press
start
button.
If
machine
does
not
rotate
in the
right
direction,
interchange
any two incoming
line
leads.
FAILURE TO START
(1)
Electric
supply
is
not
available
at
the
machine.
(2)
Fuses
have
blown
or
have not
been
fitted.
(3)
Isolating
switch
has
not
been
closed.
(4)
Lock-off
or
stop
button
has
not
been
released.
STOPPAGE DURING OPERATION
AND
FAILURE TO RESTART
(1)
Fuses
have
blown.
(2)
Overloads
have
tripped.
They will
reset
automatically
after a short
time,
and
the
machine
can
be
restarted
in
the
usual
manner.
ADJUSTMENT
For a finer
overload
setting,
set
the
load
indicator
to a
lower
value,
and
vice-versa
for a less
fine
setting.
GENERAL
Check the
earth
connection
from
time
to
time.
Users
are
recommended
to
