Construction
The
Hack
Saw
type
MOt
6-13
consists
of the
gear
head, the
com-
pressed
air
motor
with
regulator,
economy
oiler
and val
ve.
All
turning
parts
run
in
anti-fricUon
bearings.
The
gate
of
the
crank
and
the
connection
rod
are
polished.
The
saw
blade
is
fixed
on
the
connection
rod
by
means
of
the
adjusting
bolt
(69a).
The
air
motor
operates
on
the
sliding
vane
principle.
Th e
best
efficiency
of
the
motor
is
under
·a
working
pressure
of 6 atmo-
spheres
(86
lbs./sq.
in.).
The
centrifugal
governor
prevents
the
overturning
of
the
air
motor.
For
the
long
working
life
of
the
air
motor
it
is
important
to
pay
attention
to
correct
function
of
the
automatic
economy
oiler.
3.
Taking
tool
into
service
The
centrifugal
governor
is
adjusted
for a working
pressure
of
86
lbs./sq.
in.
(6
atm.).
For
other
working
pressures
the centrifu-
gal
governor
must
be
regulated
for
360
incisions
(no
load)
per
min
.
Attention!
Before
connecting
up
the
hose
should
be
blown
clear.
Mi.nimum
hose
diameter
1
/2"
(13
mm)!
The
supply
pipes
must
be
as
large
as
possible
and
the
minimum
diameter
of
the
openings
on
couplings
must
be
5
/16"
(8
mm)
.
The
oil
tank
mounted
in
the
handle
must
be
filled
and
the
jet
must
be
adjusted
.
4.
Working
To
avoid
shocks
when
cutting,
the
work
piece
must
be
fixed
strongly. Thereby
the
saw
blade
can
not
be
damaged
.
Wh
en c
utting,
the
saw
blade
has
to
be
cooled
by
suds
or
oil.
Choice

clamping device and
the
saw
blade according
to

Application
of
the
Clamping
Devices
For
pipes
up
to
4"
(100
mm)
use
the
clamping
deviceS
14-10-1.
The
clamping
chain
(14)
is
to
be
lead
around
the
pipe
and
must
then
be
fixed
in
the
hooks
of
the
strap.
By
aid
of
the
curved
handle
(6)
chain
has
to
be
tightened.
Now
set
the
hack
saw
on
the
supporting
bolt
(20)
of
the
clamping
head
(19).
The
clamping
head
is
adjustable
and
can
be
swtvelled
(for
oblique
cut).
For
profiles
up
to
270
mm
(10")
height
use
the
clamping
device
S 14-20-2.
This
construction
conforms
to a parall
el
vice.
For
larger
pipes
of
6- 14"
OD
(150 to 350
mm)
use
clamping
device
S 14-37-2
and a saw
blade
of
18
1
/2"
(465
mm)
length.
Instead
of
the
handle
(99)
you
can
fix a saw
blade
guide
S 14-35-2
at
the
gear
head
of
the
hack
saw.
(See
our
leaflet
"Off. Bl. 428".)
Support
S 14-25-1 i•s
used
for
free
hand
working
and
especially
.
for
cutting
of
corrugated
iron.
This
support
is fixed at
the
gear
head
and
in
the
bore of the
gear
housing cove
r (73)
by
removing
the two screws
(101).
6.
Maintenance
and
Lubrication
It
is
advisable
to
clean
the
tool
by
pouring
a little
paraffin
di-
rectly
into
inlet
socket
(159) at Least
once
a week ,
before
taking
it
into
use, and
whenever
it
h
as
been
out
of
serv
ice
for any
le
ngth
of
time. Then
allow saw to
run
for
about
10-15 sec
onds
to
flush
the
paraffin
and
all
accumulat
ed
dirt out of
the
motor.
After
flushing,
pour a little
oil
directly
into
the
motor
intake
socket,
as
this
will
improve
its
performance.
The
automatic
economy
oiler
fitted
takes
over
the
general
lubrication
in
ser-
vice.
Trouble
in
operation may be
due
to
the
following
causes:
insuf-
ficient
air
pressure,
poor
lubrication
or

worn

too
full
or
clogged,
ball
bearings
worn
or
damaged.
Remedies:
check
air
pressure,
clean
motor
with
paraffin
and
lubricate
well.
In ca·
se
of
doubt,
or
if
trouble
persists,
return
machirte
to
the
distributor
for
repair.
The
motor
is
automatically
lubricated
by
the
economy
oiler
built
into
the
handle.
Before
the
start
of
each
working
shift,
Ml
the
oiler
with
thin-flowing
resin-free
machine
oil
(SAE 10).
One
filling
will
last
for
one
normal
working
shift.
Oil
feed
is
easily
re-
gulated. Take
off
enq
screw
cap
to
expose
the
control
screw
,
tighten
screw
to
reduce
oil
feed,
slacken
screw
to
increase
it.
Generally,
half a turn
will
suffice.
Should
the
oiler
become
clog-
ged,
take
out
the
screw,
and
clear
the
bore
which
then
becom
es
visible
with a piece of
wire.
If
the
full
oi'ler
is
connected
to
the
compressed-air
line,
the
oil
must
clearly
be
seen
to
bubble
under
the
pressure
when
the
filler

is
open.
All
sliding
faces
of
the
crankshaft
should
be
lubricated
once
a
week
via
the
ball
oiler
on
the
housing.
It
is
advisable
to
renew
the
gear
grease
approx.
every
300
dut
y
hours. We
recommend
our

should
be
cleaned
approx.
every
900
duty
hours
and then
be
repacked
with
fresh
Fein
FK 3 ball
bearing
grease.
To
prevent overheating
of
the

fill
only
about

Setting
Governor
The
secondary-air
speed
governor
works
on
the
centrifugal
force
principle.
Depending
on
the
setting
of the
spring,
the
we
ights
will
swing
outwards
to a greater
or
less
er
degree.
To
set
the
governor, unscrew
it
from
piston
(111),
then
turn
the
two
hexagon
nuts
on
the
governor
spi
ndle
to
adjust
the
spring
force
as
follows:
unload
spring
('/2
to 1 turn
of
nut)
to
reduce
strok
ing
rate
tight
en
spring
(112
to 1 turn
in
opposite
direction)
to
increa
se
stroking
rate
At a service
pressure
of
87
lbs
./sq
. in.
(6
atm.),
the
unlo
ade
d
saw
blade
should
stroke
at
the
rate
of
360/min.
To
check,
take
off
screw
cap
(21)
at
top
of
gearbo
x,
and
then
measure crank-
s
haft
(54) revolut
ions,
which
equals
working
strokes,
at the
c
rankshaft
end
now expos
ed.
Setting
