Operators'
Manual
The
Reed-Prentice
Portable
Timberhog
Chain
Saw
is a light,
powerful
timber
cutting
unit.
It
operates
with a compressed
air
motor
which drives
an
endless
saw
tooth
chain.
An
air
supply
of
90
cu.
ft.
per
min.
at
90
to
105
Ibs.
pressure
drives
the
chain
at
the
most
efficient
speed.
The
exhaust
air
is
used
to
keep
the
chain
clear
of
chips
and
to
blow
them
away
from
operator.
The
chain
is
made of
cutter
teeth
in
the
form
of
links
riveted
together.
These
are
of
hardened
steel
and
of
such
shape
that
a
simple
filing
or
grinding
operation
keeps
the
chain
in
most
efficient
cutting
condition.
It
is
driven
by a sprocket
at
the
motor
end
and
is
guided
by
the
slots
of
the
narrow
cutter
bar. A spring
tensioned
idler
cushions
the
vibration
of
operation
and
also
allows
for
ad
justment
of
the
tension
in
the
chain.
The
chain
is
easily
removed
from
the
saw
without
disconnecting
links.
(See
Fig.
3.)
Operation
under
or
near
water
is
easily
accomplished.
There
are
no
electric
connections
that
can
be
affected
by
contact
with
water.
The
saw
operates
to
any
depth
that
divers
can
operate,
although it
is
necessary
to
increase
air
pressure
according
to
depth
unless
the
exhaust
is
piped
to
the
surface.
The
speed
of
the
motor
is
adjusted
by a throttle
incorporated
in
the
left
handle, which
directly controls the
amount
of
air
sup
plied
to
the
rotor.
A
30"
length of
hose
isolates
the
coupling
joint
from
the
operator.
Should
the
coupling
separate,
the
"wild"
hose
end
is
far
enough
away
from
the
operator
to
prevent
injury.
Oiling
Before
starting
to
operate
the
saw a careful
check
should
be
made
to
see
that
proper
quantities
of
oil
and
grease
are
available
at
the
important
points.
Figure 1 clearly
outlines
the points
to
be
inspected
and
inspections
thereon
should
be
carefully
observed.
1.
Before
starting a new
motor
pour
about a teaspoonful
of
light
oil
into
the
air
inlet.
2.
Remove
filler
cap
on
tailstock
and
fill
oil
chamber
with
light
machine
oil.
Replenish
as
used.
3.
Pump
up
air
pressure
for
pressure
lubrication
to
chain.
Make
sure
that
breather
is
closed,
by
the
knurled
knob
on
filler
cap,
before
pumping.
4.
Turn
3-way
valve to
"on"
position.
When
engaged
in
hori
zontal
cutting
the
control
above
the
blade
should
be
in
the
"on"
position.
5.
Check
pet-cock
for
oil
supply
to
cutter
bar.
6.
Check
the
grease
in
the
governor
chamber.
7.
Remove
plug
and
check
gear
box—it
should
be
full.
8.
To
oil
rotor
remove
plug
and
fill
with
S.A.E.
10
motor
oil.
With
the
oil
chamber
full
it
should
always
be
possible
to
collect
oil
on a paper
held
in
front
of
the
exhaust.
CAUTION:
Make
this
test
only
when
the
chain
has
been
removed.
9.
To
grease
governor
remove
plug
and add
light
body
grease
—about
one
tablespoonful
every
two
months.

Chain
Test
Tension
of
the
chain
is
governed
by
the
position
of
the
idler.
The
chain
tension
adjusting
handle
(Fig.
2)
is
turned
clockwise
to
pull
the
idler
back
and
tighten
the
chain.
Test
tension
in
the
chain by
lifting
it
from
the
cutting
bar.
When
tension
is
CORRECT
the
chain
will
be
lifted
%
mcn
from
center
of
the
cutter
bar.
Starting'
The
air
motor
is
started
by
slowly
turning
the
knurled
throttle
handle.
The
saw
chain
will
then
move
in
the
groove
of
the
cutter
bar.
The
cutting
side
is
that
which
moves
toward
the
motor.
Use
care
in
engaging
the
cut.
The
bumper
on
the
motor
end
is
placed
against
the
work
before
the
chain
bites
into
the
wood.
The
chain
is
traveling
toward
the
motor
when
cutting
and
the
bumper
takes
the
thrust
of
the
cutting.
Sawing
Use
all
available
power
for
cutting.
Keep
feeding
the
saw
into
the work, the
sound
of
the
exhaust
will
indicate
if the
saw
is
being
overloaded.
Only
then
should
the
cut
be
eased
up.
Binding
in
the
cut
can
also
slow
down
the
operation.
Cut
straight
through
the
log, a curving
cut
causes
binding.
If
the
cut
"curves"
examine
the
cutter
bar
for
uneven
wear.
Both
sides
of
the
groove
should
be
evenly
worn.
Minor
discrepancies
can
be
dressed
out
with a file.
When
felling, a notch
is
cut
on
one
side
of
the
tree
in
the
direction
of
the
fall.
The
final
cut
is
then
made
from
the
opposite
side.
It
is
important
to
maintain a constant
flow
of
oil
to
the
chain.
Lack
of
oil
may
be
due
to:
(1)
no
air
pressure,
(2)
filler
cap
is
loose,
(3)
breather
on
filler
is
not
closed,
or
(4)
line
is
clogged.
The
oil
supply
to
the
chain
should
be
watched.
Lack
of
lubri
cation
to
the
chain
will
also
cause
slowing
down
although
not
to
a
very
marked
extent
until
the
lack
of
oil
becomes
critical.
Lack
of
oil
feed
to
the
chain
may
be
due
to
the
following
reasons.
The
filler
cap,
or
breather
on
the
cap,
may
be loose.
If
so,
tighten
and
pump
more
air
into
the
tank.
It
is
also
very
possible
that
the
original
supply
of
air
pressure
has
been
used
up
and
will
require
repumping.
The
oil
line
may
be
clogged.
If
extra
air
pressure
will
not
clear
it,
remove
the
copper
tube
and
clean
ALL
the
passages.
A
dull
chain
will
reduce
the
speed
of
cutting.
Replace
with
a
sharp
chain
or
resharpen
the
dull
one.

Removal
of
Saw
Chain
Saw
chains
are
easily
removed
from
the
saw.
Figure 3 shows
this operation
partially
performed.
The
door
on
the
tailstock
end
is
opened.
The
tension
in
the
chain
is
entirely
removed
by
moving
the idler
to
its
extreme
"loose"
position.
The
chain
is
then
lifted
out
of
the
idler
groove
and
successively
removed
from
the
cutter
bar
and
driving
sprocket.
Saw
Chain
The
chain
is
made of a number
of
links
riveted
together.
The
outer
links
of
the
chain consist
of
the
cutter
teeth
and
the
plain
links.
The
inner
links
are
the
rakers
which
extend
below
the
outer
links
forming a guide
that
rides
in
the
groove
of
the
cutter
bar.
These
extensions
on
the
rakers
provide
the
means
for
en
gaging the
driving
sprocket.
The
combination
of
cutters
and
rakers
form a zigzag
pattern.
Figure
4 shows
that
every
set
of
six
links
forms
a
"cutting
action," or
sequence
which
is
repeated
throughout
the
chain.
SHARPENING
the
saw
chain
is a simple
operation
and
can
easily
be
performed
by
the
operator.
It
consists
merely
of
filing
the
front
cutting
edge
of
each
tooth
taking
care
that
the
original
angle
is
not
changed.
This
can
be
performed
with
the
chain
on
the
saw.
CAUTION:
When
filing
the
chain
on
the
saw
UNCOUPLE
THE
AIR
CONNECTION.
Complete
details
of chain
maintenance
will
be
found
in
the
maintenance
section
of
this
book.
Miscellaneous
A
complete
set
of
tools
is
provided.
In
addition
to
the
operations
already
listed,
keep
the
bolts
on
the
entire
machine
tightened.
A
clean
machine
will
allow
easy
inspection
for
loose
bolts
and
screws.
Check
all
bolts
and
screws
frequently.
Carelessness
in
this
respect
will
cause
excessive
wear
and
unsatisfactory
performance.

Maintenance
Manual
The
Reed-Prentice
Portable
Timberhog
Saw
operates
with
a
compressed
air
supply of
90
cubic
feet
per
minute
at
90
to
105
pounds
tank pressure.
The
air
supply
is
coupled
onto
the
end
of
the
30"
hose
which
is
attached
to
the
left
handle
of
the
motor.
The
handle
is
also
the
throttle
and
the
amount
of
air
supply
is
governed
by
twisting
this
handle.
The
30"
length
of
hose
is
provided
as a safety
device
so
that
should
the
coupling
break
loose
the
wild
end
of
the
air
hose
will
not
endanger
the
operator.
The
compressed
air
drives a vane
type
motor
in
which
is
in
corporated a governor
and
an
automatic
oiling
device.
The
auto
matic
oiling
device
supplies a light
mist
of
oil
that
lubricates
the
vanes
and
rotor.
The
power
from
the
air
motor
is
transferred
through a pair
of
bevel
gears
to
the
sprocket.
The
gear
box
requires
grease,
the
bearings
have
lubricant
sealed
within
them
and
need
not
receive
special
attention.
The
sprocket
is
mounted
on
the
bevel
gear
shaft
and
drives
the
saw
chain
which
travels
in a groove
in
the
cutter
bar.
The cutter
bar
is
rigidly
connected
at
the
motor
end
and
at
the
tailstock
end.
It
is
shaped
with a slight
radius
to
improve
the
cutting
action
of
the
chain.
The
tailstock
contains
the
idler
which
is
adjustable
and
is
used
to
remove
the
slack
in
the
chain
and
to
govern
the
tension.
There
is a spring
device
incorporated
in
the
tailstock
which
acts
as a shock
absorber. An
oil
tank
mounted
on
top
of
the
tailstock
supplies
oil
to
lubricate the
chain
and
cutter
bar.
Air
Motor
The
motor
contains a built-in
oiler
of
the
needle
valve
type
which
has
been
adjusted
for
proper
lubrication at
the
factory.
To
fill
the
oil
chamber,
remove
the
J4"
pipe
plug
in
the
cap
at
the
point
marked
"Oil."
This
chamber
should
be
filled
with a good
grade
of
SAE-10
or
200
viscosity
oil
for
each
eight
hours
of
use.
Before
starting a new
motor
or
one
which
has
been
idle
for
a
week
or
more,
check
the
oil
chamber
in
the
cap
to
see
that
it
is
full.
Pour a teaspoonful
of
oil
directly
into
the
motor
intake
line.
Grease
should
be
added
to
the
governor
chamber
about
once
every
two
or
three
months.
The l/&"
pipe
plug
on
the
side
of
the
motor
cap
provides
an
opening
for
adding
this
grease.
Any
light
body
grease
is
satisfactory.
Do
not
overpack
the
governor
chamber
with
grease,
as
all
excess
will
blow
out
of
the
exhaust.
About
one
tablespoonf
ul
per
application
is
sufficient.
It
is
very
important
that
the
air
strainer
in
the
throttle
handle
(E3)
be
kept
clean
to
avoid
loss
of
power.

valve
assembly
apart,
press
the
plug
(48)
out
of
the
back
end
of
the
governor
cage
by
pressing
on
the
protruding
end
of
the
stem
on
the
governor
valve
(51).
The
governor
valve
(51)
should
be
checked
for
freeness
in
the
cage
(50).
Any
sticky spots
in
this
unit
should
be
eliminated
to
insure
proper
operation.
Inspection
of
the
vanes
(56)
can
be
made
by
unscrewing
the
governor
body
(57)
(right-hand
thread)
from
the
rotor
(55)
and
removing the
top
end
plate
(42).
The
top
end
plate
(42)
fits
snugly
into the
housing
and
can
be
removed
after
the
governor
body
has
been
taken
out
by
striking
the
edge
of
the
motor
housing
with a fiber
mallet.
After
the
top
end
plate
is
taken
off,
the
vanes
(56)
can
be
lifted
out
of
the
motor
without
any
further
dis
assembly.
Removal
of
the
rotor
necessitates
the
disassembly
of
the
pinion
(E6)
(Fig.
7)
and
pinion
spacer
(E5)
(Fig.
7),
after
which
the
rotor
can
be
pulled
out
of
the
motor.
When
assembling a rotor,
always
pull
up
tightly
on
the
lock
nut
(E8)
(Fig.
7)
which
holds
the
pinion
in
place.
This
will
pull
the
rotor
up
against
the
end
plate
to a point
where
it
may
actually
rub a little.
In
pulling
up
tightly
on
the
governor
body
(57)
when assembling
the
other
end
of
the
motor,
however,
the
rotor
will
be
pulled
toward
the
upper
end
plate,
locking
it
in a freely
suspended
position
between the
two
end
plates.
The
rotor
bearings
(43)
on
these
motors
are
supplied
in
pairs
only.
Always
keep
pairs
together.
Never
replace
just
one
rotor
bearing.
If
bearing
pairs
are
mixed up
or
an
old
bearing
is
used
with a new
one,
the
rotor
is
not
apt
to
be
properly
locked
in
position
and
rubbing
on
the
end
plates
may
result.
It
is
absolutely
necessary
when
installing a new
pair
of
bearings
that
they
be
assembled
into
the
motor
with
the
same
back
to
back
assembly
as
when
packed
in
the
box
by
the
bearing
manufacturer.
If
it
is
ever
necessary
to
remove
the liner
or
bottom
end
plate
from
the
motor
housing,
heat
the
motor
housing
around
the
outside
with a torch.
This
will
allow
the
housing
to
expand
enough
to
permit
these
parts
to
drop
out.
Heating
of
the
housing
should
be
done
as
rapidly
as
it
is
possible
to
prevent
the
heat
from
conducting
to
the
bottom
end
plate which
would
also
expand.
Removal
of
these
parts
should
seldom
be
necessary.

in
the
Parts
List
section
show
the
assembly
of
the
gear
box
unit.
E1A
is
the complete
rotor
assembly.
The
bevel
pinion
(E6),
the
spacer
(E5),
and
the
key
(E4)
are
assem
bled
to
the
shaft
on
this
rotor.
They
are
locked
in
place
with
the
lock
washer
(E7)
and
the
lock
nut
(E8).
These
parts
should
be
assembled
to
the
rotor
before
the
rotor
is
placed
into
the
main
housing
(E23).
Note
that
there
is a pin
which
projects
be
yond
the
rotor
assembly.
This
pin
locates
the
several
parts
of
the
rotor
housing
and
must
fit
into
the
hole
drilled
into
the
main
housing.
It
is
helpful
when
assembling
this
rotor
to
use a dummy
pin.
Such a dummy
pin
should
be
about
twice
as
long
as
the
rotor
assembly
and
should
be
inserted
in
the
hole
in
the
main
housing
(E23).
The
regular
pin
is
then
removed
from
the
rotor
(E1A)
and
the
entire
assembly
is
placed
in
the
main
housing.
The
long
dummy
pin
makes
it
easy
to
line
up
the
complete
assembly
as
it
is
put
in place.
It
is
necessary
to
heat
the
housing
to
approximately
150°
F.
so
that
this
part
can
be
assembled
easily.
When
the
rotor
is
in
place
the
dummy pin
is
removed
and
the
regular
pin
is
in
serted.
The
governor
(E1C)
is
also
put
in
place
and
the
cap
(E1B)
is
assembled
with
the
gasket
(E1D).
Sprocket
Shaft
The
parts
for
the
sprocket
shaft
are
assembled
in
the
order
as
shown
in
Fig.
7.
The
key
(E14)
fits
into
the
key
slot
on
the
shaft
(E1S).
The
parts
(E13), (E12),
and
(Ell)
are
then
assembled
in
the
order
named.
The
bearing
(E10)
is
assembled into
the
end
cap
(E9).
It
will
be
necessary
to
heat
this
end
cap
before
assembling
the
bearing.
The
bearing
(El7)
is
assembled
into
the
steel
bearing
housing
(E18).
This bearing
is
of
the
single
seal
type
and
the
sealed
end
should
be
toward
the
sprocket.
The
bear
ing
and
support
(E18)
are
placed
into the
main
housing
(E23).
The
shaft
assembly,
consiting
of
(E15), (E14), (E13), (E12),
and
(Ell),
is
put
in
place
with
the
threaded
end
extending
through
the
bearing
(E17).
The
end
cap
(E9)
assembled
with
the
bearing
(E10)
is
then
put
in
place
in
the
housing.
If
the
two
bevel
gears
have
been
properly
assembled
they
should
mate
properly.
The
pipe
plug
on
the
top
of
the
main
housing
is
located
to
allow
the
bevel
gear
engagement
to
be
seen
when
the
gear
box
is
assembled.
The
key
(E16)
is
assembled
along
with
the
sprocket
(E19).
The
extended
hub
on
the
sprocket
is
assembled
in
the
direction
of
the
bearing
(E17).
The
washer
(E20)
and
nut
(E22)
are
then
used
to
securely
lock
the
sprocket
in
place.
When
the
nut
is
being
drawn
up
tight
it
is
necessary
to
keep
the
sprocket
stationary
so
that
the
shaft
will
not
rotate.
The
gear
box
requires
J/£
Ib.
of
Semi-Fiber
grease
similar
to
Socony
BRB
J2
grease
or
equivalent;
for
temperatures
below
32°
high

Oil
is
recommended.
For
extreme
low

can
be
mixed
with
kerosene.
The
cutter
bar
and
guard
are
attached
to
the
main
housing
by
bolts
and
nuts
(E26), (E27),
(E28).
The
bumper or

FIG.
8—TAILSTOCK
PARTS
(See
Fig.

Page 19
Tailstock
The
main
function
of
the
tailstock
is
to
provide a spring
tension
ball
bearing
idler
to
support
the
cutting
chain
at
the
tailstock
end
of
the
saw.
The
spring
tension
acts
as a shock
absorber
for
the
saw
chain
in
operation.
The
chain
is
removed
from
the
cutter
bar
by
moving
the idler
until
the
slackness
of chain
permits
its
removal
from
the
groove
and
sprocket.
A
3-way
oiler
valve
is
provided
on
the
oil
reservoir
to
ensure
a
continuous
flow
of
oil
to
the
cutter
bar
and
chain
whether
cutting
horizontally
or
vertically.
The
ball
bearing
(H9)
used
in
the
idler
is
of
the
completely
sealed
type
and
should
require
no
further
greasing.
The
bearing
is
assembled
to
the
idler
(H8)
with a light
press
fit.
If
necessary
the
bearing
can
be
easily
removed,
using a small
arbor
press.
Care
should
be
taken
that
the
bearing
is
not
damaged
by
forcing
on
the
inner
race.
The
idler
is
held
in
cantelever
suspension
by
the
idler
stud
(Hll)
which
screws
into
the
chain
tension
bracket
(H4).
Slots
in
this
bracket
fit
the
slide
in
the
tailstock
casting
(H12)
and
hold
the idler
in
alignment.
The
sequence
of
assembly
of
the
bracket,
idler,
spacers,
etc.
is
plainly shown
in
the
Fig.
9.
The
helper's
handle
(H3)
is
assembled
to
the
tailstock
casting
after
the
sprocket
and
bracket
assembly
is
in
place.
The
chain
tension
spring
(H2)
is
placed
inside
the
handle
before
the
adjust
ing
knob
(HI)
is
screwed
onto
the
idler
bracket
stud.
The
adjusting
knob
controls
the
position
of
the
idler
which
puts
more
or
less
tension
upon
the
chain
as
required.
The
tailstock
also
contains
the
oil
reservoir
which
supplies
oil
to
the
cutter
bar
and
the
chain. A small
air
pump
(HIS)
is
used
to
set
up a pressure
in
the
tank and
force
the
oil
into
the
cutter
bar
during
the
cutting
action.
The
oil
is
fed
from
the
reservoir
to
the
cutter
bar
through
the
oil
line
and
fittings
(H17),
(HIS),
and
(H19).
A
pet
cock
(HIS)
is
provided
for
adjusting
the
flow
of
oil.
To
assemble a 3-way oiler
valve
insert
Alien
pipe
plug
(H26)
into
dial
end
of
oiling
stem
(H25).
Place
one
gasket
(H41)
on
oiling
stem
(H25)
and
insert
into
opening
in
oil
reservoir
on
casting
(H12).
Oiling
stem
must
be
inserted
from
the
PET-
COCK
side.
Fit
gasket
(H41)
over
end
of
oiling
stem
(H25)
making
sure
that
gasket
fits
snugly
into
the
counter-sunk
space
in
casting
(H12).
Collar
(H30)
is
fitted
onto
stem
(H25)
and
is
held
in
place
by
taper
pin
(H31).
Ball
(H29),
spring
(H28),
and
set
screw
(H27)
should
be
inserted
in
this
sequence
into
opening
provided
in
oil
reservoir
tank.
These
serve
as a detent
for
stem
(H25).
During
disassembly
it
is
important
that
these
three
parts
be
removed
prior
to
removal
of
oiling
stem
(H25).
The
cutter
bar
fits
into a slot
on
the
end
of
the
tailstock
casting
and
is
held
in
place
by
the 3 bolts
and
nuts.
This
cutter
bar
is
so
designed
that
it
can
be
assembled
in
any
position
and
at
all
times
the
necessary
oil
and
bolt
holes
will
be
properly
lined
up.
The
oil
from
the
reservoir
is
supplied
through a slot
on
the
side
of
the
cutter
bar
to
the
bottom
groove.
Before
attaching
the
cutter
bar
make
sure
that
this
groove
is
clear
so
that
the
oil
can
easily
reach
the
chain.

Chain
The
construction
of
the
Timberhog
saw
chain
is
illustrated
in
Fig.
10
which
shows
that
every
set
of
six
links
forms a "cutting
action."
Each
cutting
action
consists of a sequence
as
follows:
left
cutter,
right
raker,
right
cutter,
left
raker,
left
cutter,
and
center
raker.
To
balance
the
chain
one
cutting
action
or
sequence
starts
with a left
cutter
and
the
next
with a right
cutter.
The
sequences
are
repeated
throughout
the
entire
chain.
The
links
or teeth
are
riveted
together
and
the
entire
chain
is
supplied
as
one
endless
unit.
The
rivets
are
made
with a shoulder
against
which the
outer
or
side
cutters
are
riveted.
The
shoulder
properly
spaces
the
side
cutters
so
that
clearance
is
maintained
with
the
center
links
or
rakers
to
provide a flexible
chain.
It
is
generally
not
necessary to
do
more
than
file
the
front
edges
of
the
teeth
to
keep
the
saw
cutting
efficiently.
However,
occasionally
other
maintenance
is
required.
Sharpening
the
Saw
Chain
To
sharpen the
saw
chain
it
is
filed
or
ground
on
the
front
cutting
edge
as
shown
in
Fig.
11.
Take
care
that
the
original
angle
is
not
changed
by
filing.
Occasionally
when
cutting
frozen
or
exceptionally
hard
wood
it
is
necessary
to
set
back
the
angle
of
the
cutting
teeth
and
under
cut the
raker
teeth.
This
filing
operation
should
not
be
performed
unless
absolutely
necessary.
The
change
of
angle should
be
slight
and
is
governed
by
the
hardness
of
the
wood
to
be
cut.
18
Page 23
Resetting the
Saw
Chain
If
the
chain
is
binding
in
the
cut
it
may
be
necessary
to
reset
the
cutting
teeth.
Resetting
consists
of
bending
the
cutter
teeth
outward
so
that a wider
cut
will
result,
giving
more
clearance.
This
operation
should
be
performed
with a setting
tool
so
that
the
set
in
all
the
teeth
will
be
uniform.
Use
only
enough
set
to
clear
the
chain
as
too
much
set
reduces
the
efficiency
of
the
cutting
chain.
Jointing
the
Saw
Chain
Jointing
the
saw
chain
consists
of
grinding
or
filing
the
top
of
the
rakers
so
that
they
are
lower
than
the
cutter.
The
clearance
for
the
rakers
is
approximately
1/32
of
an
inch.
A
flat
gage
is
provided
which
can
be
used
to
gage
the
clearance
properly.
Replacing
Damaged
Teeth
To
remove a damaged
cutter
it
is
necessary to
grind
or
file
the
heads
from
the
two
rivets
that
hold
the
plain
link
paired
with
the
cutter.
Do
not
attempt to
remove
one
rivet
at a time
because
these
are
made
with a shoulder
and
will
not
pass
through
the
cutter.
A
cold
chisel
can
be
used
to
separate
the
plain
link
from
the
rivets.
The
damaged
tooth
together
with
the
rivets
is
then
removed
from
the
chain.
The
plain
link may
be
used
again.
Before
replacing
the
cutter
insert
rivets
in
the
two
rakers.
Assemble
the
plain
link
and
cutter
in
pairs
and
peen
over
the
heads
of
the
rivets.
Make
sure
that
assembly
is
complete
before
rivetting.
The
replaced
tooth
should
be
filed
and
jointed
so
that
it
will
match the
other
teeth
in
the
chain.
