2. Construction
The Hack Saw type MOt 6-13
consists
of
the
gear
head,
the
com-
pressed
air
motor with
regulator, economy
oiler and
valve.
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
work
ing 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.
When cutting, the saw
blade
has
to
be
cooled
by
suds or oil.

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
o
f
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
parallel
vice. For
larger
pipes
of
6-
14"
OD
(150
t
o
350
mm) use clamping device
S 14-37-2 and a saw blade of 18
1 /2"
(465 mm)
lengt
h. 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
cover (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 we ek
,
before
taking
it into
use,
and whenever it
h
as
been
out of
se rv
ice
for
any
length
of
time. Then
allow saw
to run for ab ou
t
10-15
sec
onds
to
flush the
paraffin and all
accumulated
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:

ficient air pressure, poor lubrication
or
