CONCR~TE SAW OPERATING INSTRUCTIONS
ASSEMBLY
.
Handles
must
be turned around and attached
properly.
Place
in position,
set to
desired height
and securely tighten knobs.
Note
that
the handles
can be placed
in
a
tilted position for
·
improved leverage.
'
·
2.
Connect
the negative
battery cable end
to the
negative battery
terminal.
Tighten the capscrew and nut securely to assure
proper
electrical
contacts.
3.
Be
certain to
check·
engine and
transmission
oil levels and
service before using.
Refer to
engine manual for detailed
information.
4.
On electric saw models,
the
proper size power
cord
must be
.
provided by
the
purchaser,
for
wiring motor starter
to
power
source.
Refer to chart on
Inside of starter box cover
for
recom-
mended
wire
gauge.
GENERAL INSTRUCTIONS
1.
Be
certain you
have the
correct
diamond
or abrasive blade.
Contact
your
authorized servicing dealer for the correct specifi-
cation. Getting
the
correct blade
will
make a tremendous
difference in your blade costs and performance.
2.
The
blade shaft
flange
and arbor
must
be
inspected for
damage
and cleaned before
mounting
blade.
If
damaged,
replace
bad
parts.
Inspect
blade for damage
to
arbor hole and
flange
area
before attempting
to
mount blade.
3.
Mount the
blade solidly and
firmly
on blade shaft arbor
using
the wrench
provided.
Make
sure
the
arrow on both
the
blade
and
the
blade guard are pointing
in
the same direction of
rotation.
The.
lock
pin
in
the outer
blade
flange must go
completely through
the
blade and
into the
matching hole in the
inside blade flange.
Tighten blade flange bolt very securely.
(Approximately
50
ft.
lb.). Note
that
the
blade shaft bolt on the
right hand side has
left
hand
threads,
which
tightens
by turning
counter-clockwise. The blade shaft bolt on
the left hand
side
has
right hand
threads, which
tightens by turning clockwise.
4.
WARNING:
Do
NOT
operate
without
proper blade guard
in
place.
Do
not operate
with
front of blade guard raised.
Blade
exposure cannot exceed
180
degrees when
cutting.
·
5.
The front
and rear pointer must be checked for alignment
with
blade.
It must
be
in line
with a
blade
mounted on the
blade
shaft.
Use
a chalk
line
or
long
straight edge to verify alignment.
6.
Do NOT
use conventional (wet) diamond blades without
waterl
You
must have from
2-1/2
to
5 gallons of
water
per
minute
flowing
over the blade
for
proper cooling and
to
get maximum
blade life. For
wet
sawing, be sure
the
spray
holes in the
blade
guard
water tubes
are open and
that
each side of
the blade
has an adequate supply of
water.
Test
your
water
supply for
pressure and quantity (flow)
before
starting to saw.
7.
Saw
in
a straight line.
Mark
the cutting
line
clearly so
the
saw
operator can
follow
the line
without
difficulty.
The
saw should
not be twisted from side to side
trying
to
force the blade back
on line.
a.
Saw only as
deep
as the specifications and
job
conditions
require.
This
will
save blade life and
reduce
sawing costs.
Sawing excessively deep
is wasteful
and should be avoided.
TO START SAW
1.
Fill the
fuel
tank
and
check the engine oil
level. Refer
to the
engine manual for
details.
CJ .
WARNING:
Always have the hydrostatic
transmission
speed
control lever in the
neutral
position or disengage
the
transmission drive system before starting the engine.
3.
Make
sure
emergency,
stop button is
in
the UP position.
4.
Place water safety
switch
in
the
OFF position
if equipped
on saw.
5. Start engine.
Follow
procedure
in
engine manual.
6. Let engine
warm up
at half
throttle .
7.
All
sawing
Is done
at
full
throttle. Governor
is factory
set for
correct engine speed.
Do
not change
the governor
setting
unless
you
are changing
the blade
capacity and
need to
adjust
the blade shaft speed. (See chart
In
saw
parts·
list for
correct
blade speeds and governor settings.)
TO MANEUVER SAW
1.
Raise blade as high as
possible
so
blade will
not
strike
pavement
when
maneuvering by
turning the
handwheel
counter-clockwise.
2.
Extend
handles
to
desired location to
achieve
best
leverage
.
Lift rear wheels
just above
pavement
and maneuver saw as
desired
.
.
3.
To
maneuver
with power,
engage
the transmission drive, if
nec-
essary, and move speed
control
lever
forward or
backward from
neutral
position. This lever
permits
Infinitely
variable
ground
speed (up
to
130
feet per
minute)
in forward and
reverse.
WARNING:
When
engaging the
transmission, be
sure
the
speed control
lever is
at neutral
to
avoid
movement
of
the
saw.
When maneuvering with
power,
the
engine should
be
running
at one-half
throttle
or more so
hydrostatic transmission
can
operate efficiently.
For
maximum speed
forward
or reverse,
the
engine must be running at
full
throttle.
TO START SAWING
• 1
.
Follow all the
Instructions
outlined above.
2.
Align blade with
cut.
For wet
sawing, open water valve
FULL
open.
Set
water
safety switch to ON
position, if
equipped on
saw.
If
engine stops, recheck
water
supply.
The
water
safety
switch will automatically
shut
off
the
engine if
proper water
pressure is not supplied.
Note
that
the
safety switch cannot
detect
a clogged water
line
because
it
senses pressure, not
flow.
3.
Lower the
blade
into
the
cut (never deeper than
required) by
slowly turning
the
handwheel clockwise. Stop lowering
when
blade contacts
pavement. At this
time
set
cutting depth indicator
to
zero, then
continue
lowering
until the desired cutting depth
is shown on the cutting depth
indicator.
4.
During cutting; do not exert excessive side pressure on handles
to steer. Use only enough pressure to follow
the
previously
marked
line.
5.
Move the
speed control handle
forward
slowly
until the
desired
cutting speed
is
obtained allowing the blade
to
cut and not
climb out
of the
cut or stall.
6.
If the
saw should stall
for any
reason, raise
the
blade completely
out of the cut and disengage the self-propelling
transmission
before starting engine again.
7.
When
lowering the bljide into
a
partially-made cut,
use
extreme
care to be certain
the
blade is perfectly aligned
within the
cut
before starting to saw again.
Do
not
force
blade into
material
by
lowering
the blade
too
fast or by propelling too
fast while
sawing.
AT FINISH OF CUT
1.
Move
speed control lever
to neutral
position.
2. Bring the blade out of
the
cut by
turning the
handwheel counter-
clockwise.
Raise
blade
high
enough to clear
the
pavement
when
maneuvering
the
saw.
3. Turn off water valve.
If
saw is
equipped
with the optional electric
water
pump, make sure it is turned off.
4. Close engine
throttle
to idle position. Let engine cool down
before stopping.
5.
Do not leave
the
saw until the blade and saw has completely
stopped.
