3  Transport (Blade Removed)
(See Figures 1, 2, and 5)
Turn engine off. Set SPEED CONTROL LEVER 
(1O)  to  STOP  POSITION  (1BB).  Remove 
DIAMOND BLADE (2E) before transport.
When moving the saw up and down ramps, with engine 
on, use extreme caution.
•  
To go DOWN a ramp drive the saw FORWARD slowly.
•   
To go UP a ramp, back the saw in REVERSE slowly.
Rear Pivot Model: Machine must have DIFFERENTIAL 
SWITCH  (1J)  in  the  center  “Lock”  position  if  moving 
saw  up  or  down  ramps!  DO  NOT  shift  DIFFERENTIAL 
SWITCH  (1J)  to  the  Left  “Pivot”  position  if  moving  the 
saw up or down ramps!
For steep ramps, always use a winch. Never 
stand below the machine.

POSITION (1BB).
•  Push Handle Bars (1B) inward and tighten Knobs (1A).
Block  the  saw  in  place  or  secure  it  into 
place using the factory installed TIE DOWN 
LUGS (3-1H, 3-2H), front and rear to prevent 
movement during transport.
4  Check Before Starting
Take  into  account  the  working  conditions 
from health and safety point of view.
•  Fuel (Check the engine maintenance manual.) Use No. 
2  Diesel  Fuel  for  normal  conditions.  Fill  tank  at  FUEL 
TANK FILL (5E) location.
•  Check that the engine oil level is correct. Because the 
engine  often  operates  at  an  angle,  check  the  oil  level 
(with engine horizontal) frequently to ensure that the oil 
level never falls below the lower mark on the ENGINE 
OIL  DIPSTICK  (5B).  SAE  15W40  CF,  CF-4,  CG-4,  or 
CI-4 engine oil is recommended.
• For start up, refer to the Yanmar engine manual.
•  Push the SPEED CONTROL LEVER 
(1O)  forward  for  FORWARD  saw 
movement, or to rear for REVERSE 
saw movement. The further you push 
the lever the faster the speed.

6  Starting The Saw
(See Figures 1, 2 and 5)
Always pay extreme care and attention to the 
preparation of the machine before starting. 
Remove all wrenches and tools from the floor 
and the machine. 
Always  keep  blade  guard,  belt  guards  and 
fan guards in place. 
•  Follow  all  operating  instructions  and  warnings  in  this 
manual and on the machine. 
•  Close the WATER VALVE (1T). 
•  Mark the surface to be cut by drawing a line where the 
cut is to be made. 
•  Pull out Handle Bars (1B) to desired length and tighten 
Knobs (1A). 
•  Lower the Front Guide (6D) and align the Front Guide 
(6D), Rear Guide (6F) and DIAMOND BLADE (2E) with 
the line on the surface. 
•  
To start the saw when no water pressure is present, set 
the WATER SAFETY SWITCH (1L) to “0” (OFF). 
•   Set  SPEED  CONTROL  LEVER  (1O)  to  the  STOP 
POSITION (1BB). Saw will not start unless the SPEED 
CONTROL  LEVER  (1O)  is  in  the  STOP  POSITION 
(1BB).  Check  to  be  certain  the  TRANSMISSION 
BYPASS VALVE (6J, Front Pivot Models Only) is closed 
in the down position.
•  Set  the  BLADE  CLUTCH  SWITCH  (1V)  (if  equipped) 
to “0” (OFF).

•  Start  the  engine  using  the  ENGINE  START  SWITCH 
(1H).  Follow  the  procedure  in  the  engine  manual.  In 
Cold conditions, pre-heat the engine by holding in the 
ENGINE START SWITCH (1H) for 15 seconds.
•  Let the engine warm up for several minutes with ENGINE 
THROTTLE (1F) at the low speed setting. 
•  When ready, open the WATER VALVE (1T). 
•  Set WATER SAFETY SWITCH (1L) to “1” (ON). 
Test  for  adequate  water  supply.  (2.5  -  5.0 
GPM)  (10  -  20  Liters  per  Minute)  Low  water 
flow will cause damage to diamond blades.
•  For  Machines  without  the  Optional  BLADE  CLUTCH 
SWITCH  (1V):  Pull  ENGINE  THROTTLE  (1F)  out  to 
set  engine  RPM  at  3200,  as  shown  on  the  ENGINE 
TACHOMETER (1G).
See chart for the appropriate blade shaft and engine 
speeds for specifc blade sizes. 
•  Move the saw forward or reverse (Standard and Front 
Pivot Models) slowly by pushing or pulling on the Speed 
Control  Lever  (1O).  Move  the  saw  slowly  to  prevent 
stalling  the  blade.  Make  sure  the  Front  Guide  (6D), 
Rear  Guide  (6F)  and  DIAMOND  BLADE  (2E)  stay  on 
the line. 
Rear Pivot Model Only: For the Rear Pivot Model, aligning 
to the cutting line can be made using the pivot feature on 
the machine. Simply move the DIFFERENTIAL SWITCH 
(1J) to the Left position (Pivot), and then use both hands to 
push down on the HANDLEBARS (6G), and the machine 
can be pivoted from side to side to align with the cutting 
line. After the saw is properly aligned to the cutting line, 
toggle  the  DIFFERENTIAL  SWITCH  (1J)  to  the  Center 
(Lock) position.
•  Set the BLADE CLUTCH SWITCH (1V) (if equipped) to 
“1” (ON) to engage the Blade Drive when engine is at 
IDLE SPEED (1200 RPM or less)! When clutch engages 
and blade is at idle speed, pull out ENGINE THROTTLE 
(1F) and set engine RPM at 3200.
•  Lower the saw by pressing the TOGGLE SWITCH (1P) 
on the SPEED CONTROL LEVER (1O) downward until 
the  DIAMOND  BLADE  (2E)  is  at  the  desired  cutting 
depth (See “Blade Cutting Depth Information”). 
Be  certain  that  water  flow  is  abundant  for 
wet sawing.
Blade Cutting Depth Information: 
The saw is equipped with a BLADE DEPTH INDICATOR 
(1Q) which has two number ranges. The Orange and White 
number ranges are used for two different purposes:
1)   
The “Depth”  number  range,  indicated  by the Orange 
color, shows the current Cutting Depth of the DIAMOND 
BLADE  (2E).  As  the  saw  is  lowered,  the  BLADE 
DEPTH INDICATOR (1Q) needle travels through these 
numbers in increasing order. Or
2)  
The  “SMD”  or  “Set  Maximum  Depth”  number  range, 
indicated by the White color, is the uncut depth of the 
DIAMOND BLADE (2E). The desired maximum cutting 
depth is pre-set using the BLADE DEPTH INDICATOR 
(1Q). It can be used with or without the BLADE DEPTH 
STOP SWITCH (1M) feature. As the saw is lowered, 
the BLADE DEPTH INDICATOR (1Q) needle travels 
through the White color number range in decreasing 
order,  indicating  the  unfinished  depth  of  cut.  When 
the BLADE DEPTH INDICATOR (1Q) needle reaches 
“0”  position,  the  desired  maximum  cutting  depth  is 
reached. If the BLADE DEPTH STOP SWITCH (1M) 
feature  is  used  (“1”  or  “ON”  position),  the  lowering 
process stops automatically.
 
Using the BLADE DEPTH INDICATOR (1Q):
“Depth”  Mode  (Orange  colored  numbers  show  current 
cutting depth):
•  
Turn  ENGINE  START  SWITCH  (1H)  to  “0”  (OFF) 
position to STOP engine (If running).
•  
Turn  ENGINE  START  SWITCH  (1H)  to  “1”  (RUN) 
position to power electrical system.
•  
Turn  BLADE  DEPTH  STOP  SWITCH  (1M)  to  “0”  
(OFF) position.
•   Lower DIAMOND BLADE (2E) by pushing the TOGGLE 
SWITCH (1P) on the SPEED CONTROL LEVER (1O) 
downward until the DIAMOND BLADE (2E) touches the 
surface to be cut.
•  Rotate the BLADE DEPTH INDICATOR (1Q) needle to 
align to the “0” depth.
•  
As  DIAMOND  BLADE  (2E)  is  lowered  into  the  cutting 
surface, the current cutting depth will now be indicated 
by  the  Orange  text  number  range  on  BLADE  DEPTH 
INDICATOR (1Q) needle.
S M D   o r   “ S e t   M a x i m u m   D e p t h ”   M o d e   w i t h o u t  
BLADE  DEPTH  STOP  (White  colored  numbers  show 
uncut depth):
•   
Turn  ENGINE  START  SWITCH  (1H)  to  “0”  (OFF) 
position to STOP engine (If running).
•  
Turn  ENGINE  START  SWITCH  (1H)  to  “1”  (RUN) 
position to power electrical system. 
•   Lower  DIAMOND  BLADE  (2E)  by  pushing  TOGGLE 
SWITCH (1P) on the SPEED CONTROL LEVER (1O) 
downward  until  DIAMOND  BLADE  (2E)  touches  the 
surface to be cut.
•  Rotate the BLADE DEPTH INDICATOR (1Q) needle to 
align with the desired maximum cutting depth on White 
colored  number  range.  The  uncut  depth  will  now  be 
indicated  on  the  White  colored  number  range.  When 
the BLADE DEPTH INDICATOR (1Q) needle gets to the 
“0” position, the saw is cutting at the desired maximum 
cutting depth.
•  Raise the blade by pushing the TOGGLE SWITCH (1P) 
on the SPEED CONTROL LEVER (1O) upward until the 
DIAMOND BLADE (2E) is off of the cutting surface.
•  
Turn the ENGINE START SWITCH (1H) to the “0” (OFF) 
position to turn off power to electrical system.

downward  until  DIAMOND  BLADE  (2E)  touches  the 
surface to be cut.
•  Rotate the BLADE DEPTH INDICATOR (1Q) needle to 
align with the desired maximum cutting depth on White 
colored number range.
•  Set  the  BLADE  DEPTH  STOP  SWITCH  (1M)  to  “1” 
(ON) position.
•  Raise the blade by pushing the TOGGLE SWITCH (1P) 
on the SPEED CONTROL LEVER (1O) upward until the 
DIAMOND BLADE (2E) is off of the cutting surface.
•  
Turn the ENGINE START SWITCH (1H) to the “0” (OFF) 
position to turn off power to electrical system.
•   Now  the  maximum  cutting  depth  is  set.  If  the  saw  is 
raised out of the cut surface for any reason it can now 
be lowered to “Set Max. Depth” by lowering the blade 
until the saw lowering movement stops.
The  saw  WILL  NOT  lower  to  any  depth 
greater than the position set on the BLADE 
DEPTH STOP SWITCH (1Q). If a deeper cut is 
required, the BLADE DEPTH INDICATOR (1Q) 
MUST be turned to the new depth position. 
Or  push  the  BLADE  DEPTH  STOP  SWITCH 
(1M)  to  “0”  (OFF)  position  to  override  the 
Depth Stop Feature.

Turn off the WATER VALVE (1T). 
•   Let  the  Engine  run  at  idle  for  a  few  minutes  before 
shutting off. 
•  STOP  the  engine  by  turning  the  ENGINE  START 
SWITCH (1H) to the “0” (OFF) position. 
8  Incidents During Sawing
(See Figures 1-2)
If ENGINE STOPS during sawing, check the following: 
•  Engine out of fuel — Check Fuel Level at FUEL TANK 
FILL (5E) or at fuel level gauge at rear of machine. 
•  Lack  of  water  signals  the  WATER  SAFETY  SWITCH 
(1L) to stop the engine. Set WATER SAFETY SWITCH 
(1L) to “0” (OFF) and then restart the engine.
•  Excessively fast cutting speed will stall engine. 
•  RED  PALM  SWITCH  (1K)  has  been  pressed  down. 
Reset by pulling switch until it pops upward. 
•  CIRCUIT BREAKER (1Z) is tripped. Push to Reset 
I f   t h e  D I A M O N D   B L A D E   ( 2 E )   S T O P S  d u r i n g  
sawing, check: 
•  Drive belt tension is inadequate. 
•  
The BLADE CLUTCH SWITCH (1V) has been pushed 
to “0” OFF 
•  
The BLADE CLUTCH (1V) (if equipped) has an electrical 
failure or blown fuse. 
SAW LOWERS TOO FAST: 
•  
The  lowering  rate  of  the  saw  can  be  adjusted  using 
the SAW LOWERING SPEED CONTROL KNOB (1U) 
at the rear of the saw. If the saw falls too quickly, turn 
the knob on the SAW LOWERING SPEED CONTROL 
KNOB  (1U)  CLOCKWISE  until  an  adequate  lowering 
rate is set. 
If the ENGINE or BLADE STALLS, for any reason, raise 
the blade completely from the cut, inspect the machine 
thoroughly before restarting the engine. When lowering 
the  blade  into  a  partial  cut,  align  the  blade  exactly  with 
the cut to prevent damage to the blade.

9  Adjustments: Straight Line Sawing
(See Figures 1 and 4)
While  cutting,  the  saw  may  steer  to  the  right  from  the 
required  straight  line  marked  on  the  cutting  surface  (if 
the DIAMOND BLADE (2E) is installed on the right hand 
side).  If  this  occurs,  the  Rear Axle  (4E)  of  the  saw  can 
be pivoted to compensate for this situation. 
Front Pivot Model (Saw with Electric Tracking option): 
•  Push AXLE ADJUSTMENT SWITCH (1J) to the LEFT. 
Small short adjustments make large changes.

•  
Tighten loose nuts and bolts regularly, particularly after 
several hours of operation. 
•   Check  V-BELTS  (3-1M,  3-2M)  tension  regularly.  
Re-tighten V-BELTS (3-1M, 3-2M) as necessary. 
•  Remove the DIAMOND BLADE (2E) for storage. Store 
it carefully. 
•  Check  the  water  spray  over  the  DIAMOND  BLADE  
(2E) periodically. 
•  
Tighten the DIAMOND BLADE (2E) firmly on the OUTER 
FLANGE ARBOR (2C). 
•   Make  sure  the  contact  faces  of  FLANGES  (2B  &  2F), 
DIAMOND  BLADE  (2E),  and  BLADE  SHAFT  (2I)  
are clean. 
Store in a safe place out of reach of children. 
Remove all adjustment tools and wrenches. 
Store  diamond  tool  in  a  safe  place  so  it 
11  Blade Shaft V-Belt Tension
(See Figures 1-3)
This saw is equipped with high tension banded V-belts. 
The belts are properly tensioned at the factory but after 
a  few  hours  of  operation  they  will  stretch  and  become 
loose. Re-tension belts as described below.
To Tension V-Belts: 
•  
Turn  ENGINE  START  SWITCH  (1H)  to  the  “0”  
(OFF) position.
•   Open ENGINE HOOD (6E) by turning each of the two 
(2)  HOOD  LATCHES  (3-1D,  3-2D)  counter  clockwise 
for  180  degrees.  For  European  CE  models,  a  tool, 
such  as  a  screw  driver  must  be  used  to  open  these 
latches.  Rotate  the  ENGINE  HOOD  (6E)  upward,  
and  secure  it  in  the  open  position  using  the  HOOD 
SUPPORT (6H).
•  Using  the  BLADE  SHAFT  WRENCH  (2J),  loosen  
the  horizontal  clamping  bolts  (3K)  at  the  front  of  
the machine.
•  
Turn  each  of  the  two  (2)  vertical  BELT  TENSIONING 
BOLTS (3-1J, 3-2J) [at the front of machine, below the 
ENGINE  GEARBOX  (3-1A,  3-2A)]  CLOCKWISE  until 
the V-BELTS (3-1M, 3-2M) are tight.
•   Replace V-BELTS (3-1M, 3-2M) in complete sets only. 
•  For optimum V-Belt tension use Goodyear TensionRite™ 
Strips,  P/N  542  19  13-68.  TensionRite™  strips  are  
supplied with belts purchased from your dealer. 
•  Never  tension  V-BELTS  (3-1M,  3-2M)  beyond  the  
original  factory  tension.  Loose  V-Belts  result  in  poor 
saw performance and short belt life.
Replace  all  shields  and  guards.  Never  run 
Saw with out all shields and guards in place.
12  Hydraulic System
(See Figures 1-6)
The  hydraulic  system  on  this  saw  is  used  to  RAISE  /  
LOWER  the  DIAMOND  BLADE  (2E),  and  to  propel 
the  saw  FORWARD  and  REVERSE.  The  hydraulic 
system  consists  of  a  HYDROSTATIC  TRANSMISSION  
PUMP  (6K),  (2)  HYDRAULIC  WHEEL  MOTORS  (4F), 
H Y D R A U L I C   F I LT E R   ( 5 K ) ,   D C   L I F T  P U M P  ( 5 H ) ,  
HYDRAULIC  OIL  RESERVOIR  (5J),  SAW  LOWER-
ING  SPEED  CONTROL  KNOB  (1U),  and  HYDRAULIC  
LIFT CYLINDER (4G).
•  HYDRAULIC  FILTER  (5K)  should  be  changed  after 
the  first  50  hours  of  operation,  then  every  250  hours 
of operation. Fill a new HYDRAULIC FILTER (5K) with 
SAE 10W30 motor oil before installation.
•  Check  HYDRAULIC  OIL  RESERVOIR  (5J)  fluid  level 
periodically.  Maintain  oil  level  with  SAE  10W30  motor 
oil.  DO  NOT  OVERFILL,  check  oil  level  when  saw  is 
level.Fill  oil  to  bottom  of  HYDRAULIC  RESERVOIR 
FILL (5I) port.
•  Change  hydraulic  fluid  every  500  hours  of  operation. 
F i l l   H Y D R A U L I C   O I L  R E S E R V O I R   ( 5 I , 5 J )   w i t h 
approximately 2.5 quarts of SAE 10W30 motor oil. DO 
NOT OVERFILL! Check oil level when saw is level. Fill oil 
to bottom of HYDRAULIC RESERVOIR FILL (5I) port.
•  
The lowering rate of the saw can be adjusted using the 
SAW LOWERING SPEED CONTROL KNOB (1U) at the 
rear of the saw. If the saw falls too quickly, turn the knob

14   Engine / Blade Shaft / Gearbox 
Speed Adjustment 
(See Figures 1-6)
WARNING:  Serious  injury  can  occur  to  the 
operator  or  people  in  the  work  area  if  the 
rotational  speed  (n/min)  of  the  DIAMOND 
BLADE (2E) exceeds the maximum speed (n/
min) marked on the DIAMOND BLADE (2E).
ENGINE SPEED:
The  engine  speed  on  this  machine  does  not  need  to 
be  changed  from  the  factory  set  speed.  The  maximum 
engine RPM should be 3250, no load.
BLADE SHAFT SPEED:
The blade shaft speed on this machine should be checked 
before fitting the DIAMOND BLADE (2E) to the machine. 
Never install a DIAMOND BLADE (2E) if the blade shaft 
rotational  speed  (n/min)  of  the  machine  is  greater  than 
the  maximum  speed  (n/min)  marked  on  the  DIAMOND 
BLADE  (2E)!  The  BLADE  SHAFT  PULLEY  (3-1N,  
3-2N)  and  BLADE  SHAFT  FLANGE  (2B  &  2F)  may  
need to be changed if the diameter of the Diamond Blade 
is changed! 
SINGLE SPEED GEARBOX MODEL:
Each  saw  model,  as  delivered  from  the  factory,  is 
designed to operate with a specified range of blade sizes 
inside the blade guard installed on the machine. If a blade 
size outside the specified range of sizes for your model 
must  be  used,  then  the  saw  drive  configuration  must  
be changed.
If changing from a small to a very large DIAMOND BLADE 
(2E) on a machine with a single speed gearbox, the Blade 
Shaft Pulleys (3-1L), Gearbox Pulleys (3-1N), the BLADE 
SHAFT FLANGES (2B & 2F), and the Blade Guard must 
be changed.
For example, to change a single speed gearbox model 
from a 14” (350mm) drive to a 36” (900mm) drive:
1.  Change Engine Gearbox Pulley from 6.00” (152mm) 
diameter to 3.50” (88.9mm) diameter.
2.  Change  Blade  Shaft  Pulley  from  4.12”  (114.3mm) 
diameter to 5.60” (142.2mm) diameter.
3.  Change Blade Flanges from 4.50” (114.3mm) diameter 
to 6” (152mm) diameter.
4.  Change  BLADE  GUARD  (2H)  from  14”  (350mm)  to 
36” (900mm).
5.  Engine Speed does not change.
S e e   B l a d e   S i z e   C o n v e r s i o n   c h a r t s   f o r   s p e c i f i c 
information.
THREE  SPEED  GEARBOX  MODEL  (14-26,  18-30, 
20-36):
CAUTION:  Never  shift  the  Gearbox  (3-2A) 
with engine running! Only shift the Gearbox 
(3-2A)  with  engine  OFF!    Gearbox  damage 
could occur.
See “GEARBOX SHIFT LEVER (3-2O)” for details about 
operating shift lever.
A machine factory equipped with a Three Speed ENGINE 
GEARBOX (3-2A), while designed to minimize adjustments 
required  for  blade  size  changes,  will  require  some 
adjustments.  The machine is designed to operate with a 
specified range of blade sizes inside the factory installed 
blade guard.  Color coded information on machine, and 
information in operation manual, shows allowable blade 
sizes for current machine drive configuration.  There are 
three (3) machine drive configurations: a) 14-26 for 14” to 
26” (350 to 650 mm) blades, b) 18-30, for 18” to 30” (450 
to 750 mm) blades, c) 20-36, for 20” to 36” (500 to 900 
mm) blades.  For example, to change the blade size on 
a machine drive configuration 18-30 within these range, 
18” to 30” (450 to 750 mm), requires only that GEARBOX 
SHIFT LEVER (3-2O) be moved into the correct position 
(1,  2,  or  3).    If  the  required  blade  size  is  outside  of  the 
machine drive configuration range [below 18” (450mm) or 
above 30” (750 mm) for this example], then the machine 
drive configuration must be changed.  This may require 
shifting the GEARBOX SHIFT LEVER (3-2O), changing 
BLADE SHAFT PULLEYS (3-2L), GEARBOX PULLEYS 
(3-2N) and BLADE SHAFT FLANGES (2B & 2F).
Example: To change a three-speed gearbox model from a 
20” (500mm) drive to a 36” (900mm) drive, first determine 
the machine drive configuration (14-26, 18-30, or 20-36).  
This should correspond to the BLADE SHAFT FLANGE 
(2B & 2F) diameter installed on the saw.
If the machine drive configuration is a 20-36, the FLANGE 
(2B & 2F) diameter is should be 6.00” (152mm):
a) Verify proper pulley diameters are installed (See Blade 
Size Conversion charts for specific information).
b)  Shift  the  GEARBOX  SHIFT  LEVER  (3-2O)  from  
3 to 1.
c) Verify that machine drive configuration and blade shaft 
speed corresponds with information in operation manual, 
and gearbox range decal (542 19 06-00).
If  the  machine  drive  configuration  is  an  18-30,  the 
FLANGE (2B & 2F) diameter should be 5.00” (127mm):
a) Change the BLADE SHAFT PULLEY from 4.50” (114.3 
mm) diameter to 5.20” (132mm).
b)  Change  the  BLADE  SHAFT  FLANGE  from  5.00” 
(127mm) diameter to 6.00” (152mm).
c)  Shift  the  GEARBOX  SHIFT  LEVER  (3-2O)  from  
2 to 1.
d)  Verify  that  machine  drive  configuration  and  blade 
shaft speed corresponds with 20-36 drive configuration 
information in operation manual.
e)  Install  the  20-36  drive  configuration  decals  (Decals 
542 19 06-00, 542 20 65-46, 542 20 65-49 are required).  
See the “Decals and Locations” page of this manual for 
more information.
If the machine drive configuration is a 14-26, the FLANGE 
(2B & 2F) diameter should be 4.50” (114.3mm):
a)  Change  the  BLADE  SHAFT  PULLEY  from  4.12” 
(105mm) diameter to 5.20” (132mm).
b)  Change  the  BLADE  SHAFT  FLANGE  from  4.50” 
(114.3mm) diameter to 6.00” (152mm).
