EXCEL SERIES BLADES
The Excel Series of diamond blades have been designed specifically for the Soff-Cut Ultra Early Entry dry cutting system of 
green concrete. These specialty blades are designed to increase speed and life while cut\
ting a wide range of aggregates. 
Choose the correct specification of diamond blade for your area as follows:
 Purple Excel Series 1000    XL14-1000 Ultra hard aggregate and non abrasive sand
 Green Excel Series 2000    XL14-2000 Hard to ultra hard aggregate and non abrasive sand
 Red Excel Series 3000    XL14-3000 Hard aggregate, medium abrasive sand
 Orange Excel Series 4000   XL14-4000 Medium hard aggregate, medium abrasive sand
 Yellow Excel Series 5000    XL14-5000 Medium hard to soft aggregate, abrasive sand
 Black Excel Series 6000    XL14-6000 Soft aggregate, highly abrasive sand 
Step 1
Turn the key switch (located on the engine) to the “ON” posi-
tion. Press the rocker switch located in the right handle bar to 
raise the saw to its full height. Turn the key to the “OFF” posi-
tion.
Step 2
Remove the blade block cover (A) by turning the two locking 
knobs counter-clockwise. Insert the blade wrench supplied 
with the saw on the blade shaft bolt (C) on the end of the blade 
shaft in the blade block (I). Rotate the blade shaft counter-
clockwise with wrench on the blade shaft bolt (C) while push-
ing in on the blade shaft locking pin (J) located on the front of 
the saw frame. The locking pin will drop in the blade shaft and 
prevent the shaft from rotating.
Step 3
Remove the blade shaft bolt by continuing to turn the bolt 
counter-clockwise. Remove the outer arbor washer or flange 
(D).
WARNING 
Inspect the blade (K) for any damage. Do not use any 
blade that has cracks, nicks, flaws or a damaged arbor. 
Make sure the blade is marked with a maximum operat-
ing speed greater than 3500 rpm.
Step 4
Match the blade tri-arbor to the blade shaft arbor (F) and install 
the blade firmly against the rear flange (F). Insure the blade is 
installed on the tri-arbor correctly. Match the female tri-arbor of 
the outer washer or flange with the blade shaft and install the 
blade shaft bolt turning clockwise while holding the locking pin 
in. Be sure the outer flange is fully seated and firmly holding 
the diamond blade in position.
Step 5
Install a new skid plate (G) by hooking the front on the front 
blade block shaft pin. Connect the rear blade block shaft and 
the rear of the skid plate by installing the locking pin (B). 
Step 6
Install the blade cover by turning the two knobs and tighten un-
til fully seated against the blade block. Lift the front and rear of 
the skid plate to insure the blade slides through the skid plate 
freely. 
Step 7
Insure the lexan shields (E & H) move freely up and down. 
When replacing a worn blade, thoroughly clean the concrete 
from blade block and blade cover before installing the new 
blade. Discard the old skid plate and replace it with a new skid 
plate.
NOTE:  
The patented skid plate is the most important part of the 
Soff-Cut Ultra Early Entry system. If it is bent, twisted or 
damaged, spalling and raveling of a cut may result. Store 
skid plates carefully and install them properly. Install a 
new skid plate with each new blade. Never re-use skid 
plates.

OPERATING INSTRUCTIONS
Experience is very important when running the  saw. A 
skilled worker is highly recommended. Always do an inspection of the saw before starting the engine. Check the fuel (J) and 
oil level (G) per the enclosed engine manual. SAE 10W/30 oil 
and unleaded gasoline with an 87 or higher octane should be 
used. The hydrostatic tansmission use Mobil DTE 26 hydraulic 
oil or equivalent (20W with viscosity of 68).  Observe all safety 
regulations for the safe handling of fuel . Always check the 
engine oil with the saw turned off, completely lowered and 
the engine level!  Check that all controls are in good working 
order. Check for loose bolts or nuts. Check for fuel or oil leaks.
WARNING 
Do not leave the saw unattended while the engine 
is running! Always secure the saw from movement 
while unattended.
Insure all guards are secure, undamaged and properly in-
stalled.
To start the engine, turn the key switch on the “ON” (C) po-
sition. Raise the saw by pushing the rocker switch (P) on 
the right handle to the full and up position. Move the engine 
throttle lever (O) 1/3 of the way to the open position. Close the 
engine choke lever (F). The closed choke position enriches the 
fuel mixture for starting a cold engine. The open choke position 
provides the correct fuel mixture for operation after the engine 
starts and for restarting a warm engine. Start the engine by 
turning the key switch (C) to “START” position and release 
once the engine starts. Slowly close the choke lever (F). Allow  the engine to warm for a few minutes.
WARNING 
Do not operate saw if there is a fuel leak!
WARNING 
Do not operate the saw unless all guards, safety 
equipment and the engine kill switch are in place and 
operational!
Always clean the blade block assembly thoroughly before stor-
ing the saw. Always close fuel valve before transporting.

Check the air filter (D) and clean or replace if necessar y. 
Check for proper specification of blade and that the skid plate 
operates properly. Check that the blade and skid plate are in 
good condition. Make sure the work site is clean, well lit and 
hazard free.
WARNING
ASPHYXIATION HAZARD
Running an engine in a confined or badly ventilated 
area can result in injury or death due to asphyxiation 
or carbon monoxide poisoning.
WARNING
Before each use, carefully inspect the saw  for any 
damage to any of its parts and components. Pay 
careful attention to any leakage of gasoline or oil.  
Under no circumstance should the saw or any of 
its attachments be operated if you find damage or 
are suspicious that something appears to be dam-
aged.
Open the engine throttle lever to full open position for maxi-
mum engine speed by pulling the throttle knob (O) at the han-
dle. Lower the front guide to the full down position by pushing 
the control handle (N) on the right forward. 
Pulling the handle back slows the forward speed. Pulling the 
handle to the full back position stops the saw. Keep the front 
guide wheel on the cut line to insure straight cuts. Make small 
adjustments by applying side pressure on the handle to keep 
the saw straight.
Increase the forward speed if the saw is pulling left. Decrease 
the forward speed if the saw is pulling right. Do not force the 
saw. When approaching a wall, raise the front guide and use 
the triangle guide at the back of the blade block to cut the last 
few feet.
Line up the saw with the cut line using the front guide wheel 
and the triangle pointer on the back of the blade block. Pull 
the control lever (M) on the left back towards you to a full stop 
position. 
Lower the saw in to the cut by pressing the rocker switch (P) 
on the right handle to the “DOWN” position. Lower the blade to 
full depth. Move the saw forward by slowly pushing the control 
lever (M) on the left forward until the desired cutting speed is 
reached. Move the saw at about half speed for the first 200 feet to allow 
the blade to develop good diamond exposure or open up and 
promote blade life. Increase the forward speed of the saw until 
the blade and the engine are working at maximum efficiency.
Do not hit the blade block assembly against any object. Dam-
age may result. Slow the forward speed by pulling the control 
handle lever back until the saw stops. Raise the saw out of the 
cut to maximum height by depressing the rocker switch in the 
“UP” position.
The self propel function of the saw will not operate with the unit   
raised. Move the engine throttle lever to the full closed posi-
tion. Turn the engine kill switch to the “OFF” position.

FUEL HANDLING
PROPER FUEL
Taking the following precautions will lessen the risk 
of injury and property damage:
- Use extreme care in handling gasoline. It is  
  extremely flammable and the vapors are explosive. 
- Extinguish all cigarettes, cigars, pipes, and other               
  sources of ignition.
- Use only approved gasoline containers.
- Never remove gas cap or add fuel with the engine     
  running.  Allow engine to cool a minimum of 3 
  minutes before refueling.
- Never fuel the machine indoors.   
- Never store the machine or fuel container where     
  there is an open flame, spark, or pilot light such as   
  on a water heater or other appliances.
- Never fill containers inside a vehicle or on a truck   
  or trailer bed with a plastic line r. Always place    
  containers on the ground away from your vehicle    
  when filling.
- Remove the saw  from the truck or trailer and 
  refuel it on the ground. If this is not possible, then      
  refuel the equipment with a portable containe r,    
  rather than from a gasoline dispenser nozzle.
- Keep the nozzle in contact with the rim of the fuel  
  tank or container opening at all times until fueling is  
  complete. Do not use a nozzle lock-open device.
- If fuel is spilled on clothing, change clothing  
  immediately.
- Never overfill fuel tank. Always wipe off any spilled  
  fuel or oil.  Replace fuel cap and tighten
The Kohler engine is certified to operate on automotive un -
leaded gasoline with a pump octane rating (M+R) of  87 or 
higher . Fuel tank capacity is 4.5 gallon (17 liters). 
Refuel in a well-ventilated area with the engine  stopped. 
Y ou may use regular unleaded gasoline containing no more 
than 10% ethanol (E10). Do not use gasoline containing 
methanol. 
Use of fuels with an ethanol content of more than 10% (E10) 
may cause starting and/or performance problems. It may also 
damage metal, rubbe r, and plastic parts of the fuel system, as 
well as posing a fire hazard. 
Do not use fuel that is older than 30 days. Old fuel can cause 
running problems as well as fuel system damage.
The engine will not operate on gasoline 
marketed as E-85 (85% ethanol)
