MK-4000 SERIES
SAFETY
SILICA DUST WARNING
Grinding/cutting/drilling of masonry, concrete, metal and other materials with silica in their composition
may give off dust or mists containing crystalline silica. Silica is a basic component of sand, quartz,
brick clay, granite and numerous other minerals and rocks. Repeated and/or substantial inhalation of
airborne crystalline silica can cause serious or fatal respiratory diseases, including silicosis. In addition, California and some other authorities have listed respirable crystalline silica as a substance
known to cause cancer. When cutting such materials, always follow respiratory precautions.
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/docs/96-112/
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 dust masks that are specially designed to filter out microscopic particles. Where
use ON
of a dust) extraction device is possible, it should be used. To achieve a high level of dust collec)
tion, use an industrial HEPA vacuum cleaner. Observe OSHA 29 CFR part 1926.57 and 1926.103.
WARNING
Sawing and drilling generate dust. Excessive airborne particles may cause irritation to eyes, skin and
respiratory tract. To avoid breathing impairment, always employ dust controls and protection suitable
to the material being sawed or drilled; See OSHA (29 CFR Part 1910.1200).

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
fitted. 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, flanges and shafts for damage before installing the blade. NEVER use damaged or worn blade flanges.
• The blade shaft flanges must be of proper diameter for the size blade being used.
• Inspect the blade, flanges 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
configuration by checking blade shaft RPM and pulley diameters and blade flange diameters.
• Use the correct blade for the type of work being done. Use only reinforced abrasive blades or steel center diamond blades and flanges 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 flanges 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 firmly. Wrench tighten the arbor nut.

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.

MK-4000 SERIES OPERATION
MANEUVERING THE SAW
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 filter clean. Check the condition of the filter at least
every four (4) hours of operation. Clean the pre-filter (wash in soapy water and re-oil) and change the
paper filters 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 specifications and job conditions require. Remember airflow 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 flush the concrete cutting from
the cut.
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.

MK-4000 SERIES OPERATION
ENGAGING THE DRIVE UNIT
This saw is driven by a hydrostatic transmission. To engage the transmission, PULL the Neutral Engagement Handle up and turn to either direction to lock.
NOTICE
DO NOT engage the unit unless FNR Handle is on NEUTRAL.

To disengage the transmission, twist the Neutral Engagement Handle to unlock, and PUSH down.
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 flowing to the blade. Hook up the hose to the unit and turn on the water
source. Open the water valve.
NOTICE
Water flow volume can be metered by opening the water valve partially.
Next, lift the front of the blade guard and visually inspect the make sure water is flowing out of each of
the tubes. If any of the holes are blocked, flush impurities from the tube.

MK-4000 SERIES 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 first 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 finding 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
Depth Indicator and Depth Stop
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 final 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 final 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.
26
MK-4000 SERIES MAINTENANCE
ENGINE
The operation and life of the engine depends on proper maintenance. Do not start engine until engine pre-check is complete. The engine pre-check consists of checking the oil, fuel level, air filter 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 elementdaily. 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
filters is strongly recommended.
ARBOR, AXLE, DRIVE UNIT AND WHEEL BEARINGS
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 or 10W-40 oil is recommended. Check your engine manual for other recommendations.
HYDROSTATIC DRIVE UNIT & TRANSMISSION GEARBOX
The fluid shipped in your hydrostatic transmission is a fluid having a viscosity equivalent to SAE
20W20. Mobil fluid 300 or any other oil equivalent to SAE 20W20 is preferred by Eaton Transmission. The expansion tank (Marker A) is marked for proper fluid 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 fill transmission gearbox with 80-90 SAE Gear Oil to lower
edge of fill hole.
