Installing Blade/Types of Cutting
OPERATING PRINCIPLE
The following instructions were compiled to
provide you information on how to obtain long
and trouble free use of the unit Periodic
maintenance of this unit is essential Read the
manual in its entirety and follow the instructions
carefully Failure to do so may injure yourself
or a bystander
DELIVERY CHECKS
Immediately upon taking delivery of your new
equipment and before putting it into service:
 Read the handbook completely--it could save
a great deal of unnecessary expense
 Read the engine manual supplied
 Check the general condition of the equip-
ment--has it been damaged during delivery?
 Check engine oil level
 Check fuel levels
Recommended lubricants are detailed in the
CARE AND MAINTENANCE section
INSTALLING BLADE
1 Be certain that the spark plug is disconnected
or saw is unplugged
2 Remove the blade shaft nut, right hand
thread, and take off outside blade shaft collar
3 Clean off any foreign particles on the clamp-
ing surfaces of collars and on the mounting
surface of the blade
4 Place the blade on the blade shaft, lining up
the offset drive pin in the blade with the drive
pin in the mounting collar If your blade has a
directional rotational arrow, position arrow
for down cut (diamond tail trailing for down
cut)
5 Replace the outside blade shaft collar on the
blade shaft Drive pin on the inside collar
must project through the drive hole in the
blade and into the outside collar
6 Tighten the blade shaft nut (right-hand thread)
securely against star washer and outside
collar, using two wrenches supplied
7 Reconnect the spark plug or (with switch
"off") plug in the electric supply cord
TYPES OF CUTTING
Cut speed depends entirely on using the correct
blade for the material to be cut Wet or dry,
diamond blades of various specifications are
available for cutting concrete or asphalt
Manual Saws - require the operator to push the
saw through the material They are ideal for
small jobs where high productivity is not
required Stone Saw Devils are available in 7-16
hp models
Self Propelled Saws - Designed for maximum
productivity and reduced operator fatigue They
allow deeper cutting at a faster forward speed
Hydrostatic drive is typically standard on self-
propelled saws with horsepower ranges from 13-
65 Saw Devils are available in 13, 16, 18 and
20 hp models

Operation Before Starting/Cold Start/Hot
Start/To Start Sawing
BEFORE STARTING
1 Use correct blade for cutting conditions
2 Ensure arbors and collars are clean and
undamaged
3 Mount blade and tighten securely using both
wrenches
4 When wet cutting, check water jets for
adequate flow
5 Disengage transmission on self-propelled
models
6 Align pointer with saw blade
Cautio - Set u it up i a ope area. Avoid
close proximity to structures or other equip-
me t. Failure to do so may cause i adverte t
i jury to operator or other perso s i the area.
Cold Start - Open the fuel valve under the gas
tank all the way Position the engine stop
switch, located on the engine, to run Open the
throttle approximately half way and apply the
choke Pull the starter rope sharply When the
engine starts, open the choke and adjust the
throttle as necessary to keep it running Allow
the engine to warm up for a few minutes before
placing it under the load If the engine doesn't
start after (3) pulls, open choke slightly to
prevent flooding Always operate the engine at
full throttle when under load
Hot Start - Open the valve under the gas tank
all the way if it has been shut off Open the
throttle approximately half way Do not apply
the choke Pull the starter rope sharply until the
engine starts When the engine starts, adjust the
throttle Always operate the engine at full
throttle when under load
NOTE: These starting instructions are general
guidelines only Since many engine options are
available, consult the Engine Manual included

TO START SAWING
1 Start engine and let engine warm up All
sawing is done at full throttle
2 Align blade and saw with cut If wet sawing,
open water valve and turn water safety
switch on (CSP3)
3 Lower blade to touch surface and re-zero
depth gauge (CS2 and CSP3 models)
4 Lower blade into cut slowly
5 Put speed control in neutral, engage trans-
mission and move speed control lever slowly
toward forward position (CSP3 model
only)

Operation Cutting/Belts & Pulleys
6 Cut as fast as blade will allow If blade
climbs out of cut, reduce forward speed or
depth of cut
7 Use only enough side pressure on saw
handles to follow cutting line
CUTTING
Lower the blade into concrete to required depth
by turning the tilt crank counterclockwise Ease
the saw slowly forward Slow forward pressure
if the saw begins to stall
Note: For deeper cuts (4 inches/102 mm or
more), several cuts should be made in incremen-
tal steps of 1-1/2 inch (38 mm) to 2 inches (51
mm) until the desired depth is reached
Push the saw steadily forward using the front
pointer as a guide Exert enough forward
pressure so that the engine/motor begins to
labor, but does not slow down If the saw begins
to stall, retard forward movement until full RPM
is restored to the blade If saw stalls, raise the
blade out of the cut before restarting Avoid
excessive side pressure or twisting of the blade
in the cut
BELTS & PULLEYS
NEVER MAKE ADJUSTMENTS TO V-BELTS
AND PULLEYS WHILE ENGINE IS RUNNING.
1 The best tension for a v-belt drive is the
lowest tension at which the belts will not slip
under full load
2 Take up tension until the belts are snug in the
grooves Run the drive for about five (5)
minutes to "seat" the belts Then impose the
peak load If the belts slip, tighten them until
they no longer slip at peak load Most new
belts will need additional tensioning after
seating
3 Remember, too much tension shortens belt
and bearing life
4 Check the belt tension frequently during the
first day of operation Check the belt tension
periodically thereafter and make any neces-
sary adjustments
5 The two most common causes of sheave
misalignment are:
a) The engine drive shaft and the blade shaft are
not parallel
b) The pulleys are not located properly on the
shafts

Operation
Figure 1 cs002a
Dry Cutting
6 To check alignment, use a steel straight edge
See Figure 1
7 Line up the straight edge along the outside
face of both pulleys shown in the drawing
All pulleys have (2) set screws in the bottom
of their grooves Set screws require thread
locking lock tite
8 Misalignment will show up as a gap between
the pulley face and straight edge Make sure
there is clearance between arbor pulley and
saw base on both sides
DRY CUTTING
 Never operate a y saw without safety
guards i place.
 Do ot exceed maximum operati g speed
established for blade diameter.
 Do ot force blade i to material: allow
blade to cut at its ow speed.
 Do ot make lo g co ti uous cuts. Never
dry cut for more tha 30 seco ds at a time.
Allow blade to cool.
 Do ot cut or gri d with side of blade or
cut a curve or radius.
 Do ot cut dry with blades recomme ded
for wet cutti g.
 Do ot operate saw with blade diameter
larger tha machi e's capacity.
