BLADE
INSTALLATION
and
TENSION
To
install blade: With frame on a slightly raised position, remove blade guard and brushes. Place blade through
the guides, around the band wheels so blade
is
against flanges. Tighten tension screw slightly. Recheck blade
position and apply
full
tension.
Tighten the blade as much as you can with
one
hand. Replace blade guard and brushes. Recheck tension every
8 hours of use
to
offset possible
blade
stretch.
CUTTING
PRESSURE
Two
means of adjusting blade pressure
are
provided. Normally,
the
slide weight provides
adequate
range. Should
weight vary, extension spring has adjusting bolt.
Weight
of
frame should not exceed
12
to
15
lbs.
at
the handle.
Excessive weight
will
cause a distorted
cut
·and blade
damage

BRUSHES
Cleaning brushes or chip breakers
are
provided. Brushes should
be
replaced when they become clogged or worn.
Tooth stripping
is
generally
cau;ed
by
clogged brushes which fail to remove chips that become
welded
to point of
tooth.
Brush

is
mounted on tip off block close

OPERATING
INSTRUCTIONS
1.
INSTALLATION-Pump
may
be
mounted
in
any
position.
The
rotation
of
the
pump
shaft
determines
the
location of
the
pump's
intake
and
discharge
ports
,
refer
to
dimensional
drawing.
Before
installing,
turn
the
pump
shaft
in
the
direction
of
the
operating
rotation.
2.
DRIVE-Belt
or
Direct
with
flexible coupling.
BELT
DRIVE-
Overtight
belt
load will
reduce
pump
bearing
life.
Direct
Drive
recommended
for
operating
speeds
above 2100
RPM.
DIRECT
DRIVE-
Clearance
should
be l
eft
between
.
drive
shaft
and
pump
shaft
when
installing
coupling. Always
mount
and
align
pump
and
drive
shaft
before
tightening
the
coupling
set
screw.
3.
SPEEDS-100
RPM
to
the
maximum
shown
in
the
performance
table.
For
lon
ger
pump
life,
operate
at
lowest possible
speeds
.
4.
SELF
-PRIMING-Primes
at
low
or
high
speeds.
For
vertica
l
dry
suction
lift
of
15
feet, a
minimum
of
800
RPM
is
required.
Pump
will
produce
suction
lift
up
to 22 feet
when
wetted.
BE
SURE
SUCTION
LINES
ARE
AIR
TIGHT
OR
PUMP
WILL
NOT
SELF
PRIME.
5.
RUNNING
DRY
-Unit
depends
on
liquid
pumped
for lubrication.
DO
NOT
RUN
DRY
for
more
than
30 seconds.
Lack
of
liquid
will
burn
the
impeller
.
6.
CAUTION-Do
not
pump
light
fraction
petroleum
derivatives, solvents,
thinners,
highly
concentrated
or
organic
acids.
If
corrosive fluids
are
handled,
pump
life will
be
prolonged,
if
flushed
with
water
after
each
use
or
after
each
work
day.

MAINTENANCE HINTS
Crooked CuHing
-Fault
of
Machine? The Blade?
Or
Both?
Chec:k
these
Factors
1.
Tension. (See instructions
page
2)
2.
Has guide adjustment
been
altered
in
a futile attempt to make a worn
blade
cut straight?
See
guide adjustment.
3.
Is
machine excessively heavy?
See
Cutting Pressure.
4.
Are
pivot
bar
collars against
bed
so
head
is
not drifting side
ways?
5.
Are
cleaning brushes
in
good
contact with blade?
6.
Make
sure pivot
bar
turns
in
bed
and
not
in
side
_frames.
Is
It
the
Blade
?
If
the above items are
all
O.K., then
we
must suspect the blade. Here
is
how
t~
recognize a defective blade:
I.
If,
after
cut, the blade
is
plastered
to
the
side
of
the
cut and scrapes when raised up, this ·indicates
that
machine
wished
to
travel
in
vertical path but blade followed a false path due
to
irregular set, sharper side,
or
injury.
·
This
is
a typical
"out"
cut.
2.
_
If
blade stands way clear of stock as above it
is
an "in" cut.
i
A.
r-roper cutting bla.de
will
go through the stock with equal space on each side
of
the blade. A defective
bl..,de
w1l
lay over
to
one
s1de
or the other.
.;
.. ,
CAUTION-
Remember-
you
C4nnot make a defective blade cut straight by
adj~sting
the guides.
NEVER
START
A NEW
BLADE
ON
AN OLD CUT.
..
Remedies
for
Troubles
That
May
Develop
I.
BACK
OF
BLADE
BREAKING
OUT
PIECES.
Wheel Kant -blade may
be
riding
too
high on wheel
..,nd
is
scr4ping 4gainst flange.
Do
not change fac:tory
setting unless necess..,ry. See instructions on Page 3 for adjustment.
2.
BACK
OF
BLADE
SWEDGING OVER . .
Caused by loose blade, guides
too
far apart, soft blade, too
h~avy
cutting pressure or pressure
all
on
one guide,
3.
TEETH
STRIPPING
(A)
Brushes
should
be
dean
and square to blade.
Clogged
brushes
will
not remove chips
that
become welded to
point
of
tooth. · . . · ·
(B)
Multiple cutting
or
stacking -
be
sure
all
pieces
are
held securely as one loose piece
will
cause teeth
to
strip.
(C
Do
not slam blade down onto cut,
but
ease blade into
cut
until
there
is
sufficient bearing surface for the
teeth
to
bear
full
weight
of
the frame.
..
(D)
Always use
the
hydraulic
to
control descent
of
frame
when
cutting thin section material.
4.
CUTTING "IN" OR "OUT".
(A)
Set worn off one side
of
blade
due
to
hard
spot
in
material being cut.
(B)
Defective blade -Always try a new blade, properly tighti:!ned -before altering guides.
(C)
Be
sure blade
is
properly tightened. . :
(D)
A defective blade
will
not
cut
straight regardless
of
guide adjustment. ·
(E)
Too
much
pressure
on
blade -see "Cutting Pressure"
page
2.
Care
of
Hydraulic:
Frame
Control
Keep unit filled with mineral oil, viscosity I00-150
at
I
oo·F.
Low
oil
supply
will
cause head
of
ma-
chine
to
become "bouncy" as air replaces
oil
under piston.
To
correct, remove air bleed screw
on
hydraulic
top,
fill
and then remove entire unit from machine.
Pull
piston
out
4"
with unit
in
upright
position, open valve and with unit
in
an
INVERTED
POSITION force piston rod back into cylinder.
Now,
with unit
in
norm•l position,
refill
and reinstall on machine.
