Apply
upward
force
on
the
trigger
handle
to
keep
the
WallWalker®
engaged
properly,
otherwise
the
WallWalker®
spike
will
skid,
which
will
reduce
the
effectiveness.
As
the
saw
begins
to
rotate
up,
feed
force
is
developed
down
the
line
of
the
intended
cut.
Once
the
saw
is
fully
rotated
upwards,
pull
the
saw
out
of
the
cut
a
few
inches
and
re
‐
engage
the
WallWalker®
to
the
wall
and
repeat.
When
cutting
rebar,
slowly
rock
the
saw
so
that
you’re
always
cutting
concrete
as
well
as
steel.
This
will
help
keep
the
diamonds
exposed.
Also,
expect
less
chain
life
when
cutting
rebar.
Expect
more
chain
stretch
and
guide
bar
wear
when
making
“nose
buried”
cuts
for
extended
periods
of
time,
as
the
chain
does
not
have
a
chance
to
throw
the
slurry
away
from
the
nose
of
the
guide
bar.
If
the
saw
begins
to
cut
consistently
crooked,
turn
the
guide
bar
over
and
use
the
other
side.
Dress
worn
rails
with
belt
sander.
Note:
The
normal
life
of
a
guide
bar
is
two
to
three
diamond
chains.
Rebar
can
shorten
guide
bar
life.
When
using
a
new
chain,
you
can
increase
the
cutting
speed
by
opening
up
the
diamonds
by
making
a
few
cuts
in
an
abrasive
material
such
as
a
brick.
Cutting
ductile
iron
pipe
with
the
PowerGrit®
Utility
Saw
Chain
5.3
NEVER
cut
ductile
iron
pipe
with
the
saw
unless
using
ICS®
PowerGrit®
Utility
Saw
Chain.
The
following
are
safety
precautions
that
should
always
be
followed
when
using
PowerGrit
chain.
Warning!
-
Before
cutting,
make
sure
the
pipe
is
in
a
safe
condition
to
be
cut.
Support
the
work
piece
in
such
a
way
that
the
cut
remains
open
during
the
cutting
operation
and
when
the
cut
is
finished.
Pinching
the
chain
during
the
cut
could
cause
chain
breakage
and
could
result
in
death
or
serious
injury
to
the
operator.
-
If
using
the
pipe
clamp
accessory
from
ICS®,
the
clamp
must
be
attached
in
such
a
way
that
it
does
not
move
during
the
cutting
operation
and/or
when
the
cut
is
finished.
Unexpected
movement
of
the
clamp
could
cause
loss
of
control
of
the
saw
and
could
result
in
death
or
serious
injury
to
the
operator.
