MK-6000 SAW SAFETY
SILICA DUST WARNING
Grinding/cutting/drilling of masonry, concrete, metal and other materials can generate dust, mists and
fumes containing chemicals known to cause serious or fatal injury or illness, such as respiratory disease, cancer, birth defects or other reproductive harm. If you are unfamiliar with the risks associated
with the particular process and/or material being cut or the composition of the tool being used, review
the material safety data sheet and/or consult your employer, the material manufacturer/supplier, governmental agencies such as OSHA and NIOSH and other sources on hazardous materials and make
certain to comply with all product warnings and instructions for the safe and effective use of the material being cut. California and some other authorities, for instance, have published lists of substances
known to cause cancer, reproductive toxicity, or other harmful effects.
Control dust, mist and fumes at the source where possible. In this regard use good work practices
and follow the recommendations of the manufacturer/supplier, OSHA/NIOSH, and occupational and
trade associations. Water should be used for dust suppression when wet cutting is feasible. When
the hazards from inhalation of dust, mists and fumes cannot be eliminated through engineering controls such as vacuum and/or water mist, the operator and any bystanders should always wear a respirator approved by NIOSH/MSHA for the material being cut.
CALIFORNIA PROPOSITION 65 MESSAGE
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contain chemicals known (to the State of California) to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead, from lead-based paints
• Crystalline silica, from bricks and cement and other masonry products
• Arsenic and chromium, from chemically treated lumber
For further information, consult the following sources:
http://www.osha.gov/dsg/topics/silicacrystalline/index.html
http://www.cdc.gov/niosh/consilic.html
http://oehha.ca.gov/prop65/law/P65law72003.html
http://www.dir.ca.gov/Title8/sub4.html
Your risk from these exposures varies depending on how often you do this type of work. To reduce
your exposure to these chemicals, work in a well-ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to lter out microscopic particles.

SAW BLADE SAFETY
For complete safety information, refer to ANSI Safety Code B7.1 available through the American National
Standards Institute.
• ALWAYS keep area around the machine clear of obstructions and clear the work area of
unnecessary people. Keep all body parts away from the blade and all other moving parts.
• Before starting the machine, check that all guards are in position and correctly tted.
NEVER allow blade exposure from the guard to be more than 180 degrees. DO NOT
operate this machine with any guard removed.
• Inspect the blade, anges and shafts for damage before installing the blade. NEVER use damaged
or worn blade anges.
• The blade shaft anges must be of proper diameter for the size blade being used.
• Inspect the blade, anges and size shown for each blade size. DO NOT exceed maximum blade
speed shown, as excessive speed could result in blade breakage. Use ONLY blades marked with a
maximum operating speed greater than the blade shaft speed. Verify speed and saw drive
conguration by checking blade shaft RPM and pulley diameters and blade ange diameters.
• Use the correct blade for the type of work being done. Use only reinforced abrasive blades or steel
center diamond blades and anges supplied with the saw or manufactured for use on concrete saws.
DO NOT use carbide-tipped blades. Check with the blade manufacturer if you do not know if blade
is correct.
• Make sure the blade and anges are clean and free of dirt and debris before mounting the blade on
the saw. Verify the blade arbor hole matches the machine spindle before mounting the blade.
ALWAYS mount the blade solidly and rmly. Wrench tighten the arbor nut.

Page 8
MK-6000 SAW SAFETY
• Make sure the blade is not contacting anything before starting the engine.
• ALWAYS cut in a straight line. DO NOT cut deeper than 1” per pass with a dry blade. Step cut to
achieve deeper cuts. NEVER cock, jam wedge or twist the blade in a cut. DO NOT grind on the side
of the blade.
FUELING SAFETY
ON / OFF
• ALWAYS use caution when handling fuel. Shut off the engine and allow to cool before refueling.
• Move the machine at least 10 feet (3 meters) from the fueling point before starting the engine and
make sure the gas cap is on the machine and the fuel can is properly tightened.
• DO NOT touch a dry cutting blade immediately after use. These blades require several
minutes to cool after each cut. DO NOT use a blade that has been overheated (Core
has bluish color).

SAW GUIDE ALIGNMENT AND ADJUSTMENT
WARNING
This operation is performed with the engine “OFF”!
The front and rear pointers are set in line at the factory. However, the pointers should be checked
for proper alignment with the blade after every use. The following are the procedures for aligning the
pointers with the blade, with the engine shut off.
1. Using a straight edge, carefully mark a line 12 feet long on a smooth level concrete surface.
2. Place the saw parallel to the line. Lower the blade and center it over the line.
3. FRONT: With the blade centered over the line and the saw frame parallel to the line, lower the front
pointer assembly and position the pointer over the line.
4. REAR: With the blade centered over the line and the saw frame parallel to the line, loosen the
pointer and adjust up or down and ensure that it touches the line.
5. Finally, roll the saw along the entire length of the line. The saw should lead off no more than 6 inches to
the left in 12 feet of forward travel. Adjust the pointer in or out if the lead-off is outside this parameter.
6. Secure hardware.

MANEUVERINGTHESAW
WARNING
The blade is spinning whenever the saw is running. Raise the blade as high as possible when maneuvering so that the blade will not strike the pavement.
DRY CUTTING
Dry cutting blades have been specially designed for use with concrete saws. Ensure that the blade
you are using is clearly marked for dry cutting.
When dry cutting, it is important to keep the air lter clean. Check the condition of the lter at least
every four (4) hours of operation. Clean the pre-lter (wash in soapy water and re-oil) and change the
paper lters as soon as it becomes clogged. Concrete dust is very abrasive and will quickly damage
internal engine parts, causing loss of compression and eventual engine failure.
Saw only as deep as the specications and job conditions require. Remember airow helps to cool
the blade during dry cutting. Cutting too deep with one pass, or exerting excessive forward or side
pressure can be dangerous. Step cut in increments of 1 inch (25 mm) or less, for the best results.
If reinforced abrasive blades are used for cured concrete, it is usually better to saw only 1 inch deep
per pass. If deeper cuts are required, cut in multiple passes.
Thinner Diamond Blades are especially advantageous when cutting dry.
WET CUTTING
The water used on the blade is to provide coolant during cutting and to ush the concrete cutting from
the cut. Turn the water control to full “ON” when using wet cutting blades. The required ow rate is 5
to 8 gallons per minute.
FNR HANDLE
The FNR Handle moves the saw forward by pushing the lever away from the operator and moves the
saw in reverse by pulling the lever toward the operator. The further you push this lever, the faster the
saw travels.
WARNING
Before starting the engine, place this lever in NEUTRAL.
RAISE/LOWER HANDLE
The raise/lower handle controls the depth of the blade. When pulled back, the electric/hydraulic pump
will raise the blade out of the cut. When pushed forward the blade will lower. The lowering speed is
faster, the farther forward the lever is pressed.

WATER HOOK UP
Prior to starting the engine, you should hook up the water hose to the Water Inlet and visually inspect
it to make sure that water is owing to the blade. Hook up the hose to the unit and turn on the water
source. Open the water valve.
NOTICE
Water ow volume can be metered by opening the water valve partially.
Next, lift the front of the blade guard and visually inspect to make sure water is owing out of each of
the tubes. If any of the holes are blocked, ush impurities from the tube.

MK-6000 SAW OPERATION
DEPTH INDICATOR AND DEPTH STOP
The saw is equipped with a Depth Indicator and a Depth Stop. The Depth Indicator tells you
approximately how deep you are in the cut. To set the indicator, you need to rst lower the blade until
it is just touching the ground and then rotate the Depth Indicator knob to 0.
The Depth Stop is used for several cuts at the same depth. It is set by nding the desired depth and
then turning the knob until it is tight. This will prevent cutting below the “locked” level to provide a consistent depth with every cut.
Depth Stop
Depth Indicator and Depth Stop
Depth Indicator
STEP CUTTING
1. Follow general instructions outlined in the section Operating the Saw pages 20.
2. When deep sawing (more than 4”) or concrete with hard aggregate, sawing to full depth in
several cuts should be made in incremental steps of 1-1/2 to 2 inches until the desired depth of
cut is reached. In softer aggregates or asphalt, it may be possible to saw full depth in two passes.
3. Gradually move the speed control lever forward to increase the cutting speed. If the blade stalls in
the cut (which can happen when deep sawing) immediately raise blade from cut. If not done
at once, the belts will spin freely and burn. Check belts for proper tension and continue sawing at
a slower rate of speed.
4. On nal pass, lower the blade until it hits the sub-base (sandy color will appear in the water being
discharged from the cut). Raise blade approximately 1/2” from bottom. The sand and gravel
particles of the sub-base may cause premature wear or damage to the saw blade.
5. It is common, on the nal pass of the cut, for pavement to wedge blade, particularly on a hot day.
When this happens, immediately stop engine. If the blade is wedged, remove the Blade Shaft Bolt
and Outside Collar and move the saw away from the blade. To remove a wedged blade from the
concrete, use a jack hammer and carefully chip out concrete around the blade. (Pounding or
twisting the blade may cause severe damage).
6. Go slowly with a new blade until it “opens up” that is, until you can see and feel the diamonds.
7. Small corrections can be made by leaning on handles.
Deep sawing is very hard on saws and blades. Experienced operators soon get a “feel” for the
saw and are constantly on guard to slow down when they hit excessive steel or hard aggregate.

MK-6000 SAW MAINTENANCE
ENGINE
The operation and life of the engine depends on proper maintenance. Do not start engine until en-
gine pre-check is complete. The engine pre-check consists of checking the oil, fuel level, air lter and
greasing the wheel, axle, drive unit and arbor bearings. Basic engine maintenance is shown in Maintenance Schedule Table on the next page. For more detailed information, please refer to the Engine
Operator Maintenance Manual and Warranty provided with the saw.
NOTICE
When breaking-in a new saw, we recommend running the engine for one hour with no load prior to
actual use on the job.
AIR CLEANER
Due to the dusty conditions created by sawing, it is essential to check the engine air cleaner element
daily. Remove the element and shake out the accumulated dust and dirt. Wipe out dirt from the inside
cover and from the housing. Check the engine manual for washing instructions. Stocking replacement
lters is strongly recommended.
ARBOR,AXLE,DRIVEUNITANDWHEELBEARINGS
Blades shaft, Axle, Drive Unit, and Wheel Bearings should be greased according to the Maintenance
Schedule table on the next page.
WARNING
DO NOT inspect when the engine is running.
Use of high quality detergent oil of API (American Petroleum Institute) service class SF or SG. Select
the viscosity based on the air temperature at the time of operation. For temperatures below 0ºF, 5W20 or 5W-30 oil is recommended. For temperatures above 0º, 10W-30 oe 10W-40 oil is recommended. Check your engine manual for other recommendations.
HYDROSTATICDRIVEUNIT&TRANSMISSIONGEARBOX
The uid shipped in your hydrostatic transmission is a uid having a viscosity equivalent to SAE
20W20. Mobil uid 300 or any other oil equivalent to SAE 20W20 is preferred by Eaton Transmission. The expansion tank (Marker A) is marked for proper uid level. It should be checked when unit
is cold. DO NOT allow the unit to run low on oil. If the unit is low, you can add oil by removing the cap
(Marker B). Remove plug (Marker C) and ll transmission gearbox with 80-90 SAE Gear Oil to lower
edge of ll hole.
