MK-20 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.
Use appropriate NIOSH-approved respiratory protection where dust hazard may occur. Paper masks or surgical masks without a NIOSH approval number are not recommended because they do little to protect the worker. For more information about respirator programs, including what respirators have received NIOSH approval as safe and effective, please visit the NIOSH website at: http://www.cdc.gov/niosh/topics/respirators
Observe OSHA regulations for respirator use (29 C.F.R.§1910.134).
Visit http://www.osha.gov for more information.
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
http://www.P65warnings.ca.gov
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 of a dust extraction device is possible, it should be used. To achieve a high level of dust collection, use an industrial HEPA vacuum cleaner. Observe OSHA 29 CFR part 1926.57 and 1926.103.

BLADE SPEED AND THROTTLE SETTING
( (
)
) Since diamond blades cut best at specific rim-speeds, blades of different diameters must be turned at different blade shaft rpm’s.
The MK-2013/14 will run either a 16" or 18" blade and the MK-2020/24/22 HSP will run a 16" through 20" blade.
Safe, efficient, economical cutting performance will occur at the engine rpm (as read on the tachometer) stipulated on the following chart.
Blade Diameter
14"
16"
18"
20" set engine rpm to* full throttle (3500)
3200-full throttle
2850-3300

The MK-20 Series engine shaft to blade shaft ratio is 1:895.
WARNING Operating saw blades at rotational speeds greater than those recommended by the manufacturer can cause blade damage and possibly subsequent personal injury.
Never exceed 3600 rpm blade shaft speed.
* The MK-20 Series, it is possible to cause overspeeding of the blade at throttle settings above those stipulated on the above chart; DO NOT EXCEED THESE
ENGINE RPM SETTINGS!
21
MK-20 SERIES OPERATION
STANDARD OPERATION
The MK-20 Series is intended for industrial applications and operated by experienced professionals.
The operator must be aware of the machine’s capabilities and limitations. It is the operators responsibility to use this machine under safe working conditions and conform with federal, state and local codes or regulations pertaining to safety, air, pollution, noise etc...
CAUTION 1. Prior to operation of this machine the operator must determine the existence
and location of any subsurface features that may be hazardous or could
damage the equipment, (i.e. electric cable, natural gas line etc...)
2. If the saw should stall for any reason, raise the blade out of the cut before
restarting the engine.
3. DO NOT crank engine for more than 30 seconds at a time. If engine fails to
start, wait about 2 minutes between cranking periods to prevent starter from
overheating.
4. Allow engine to warm up at least 3 minutes before applying load. When
engine is warm, throttle may be used out to maximum position. Special pre
cautions should be taken during the break-in period as specified by the
Engine Manual.
(A)
Use the Depth Control Wheel to raise the blade clear of the floor.
(B)
Attach the cooling supply hose to the Cooling Inlet, if wet cutting.
(C)
Layout and mark the area to be cut using a chalk-line. Align Pointer and Blade to chalk-line.
(D)
Place Transmission Speed
Lever in Neutral.
(E)
Verify Neutral Engagement Handle is down, in Neutral. Choke engine as required for cold starting.
22
(F)
Push Engine Throttle Handle up half-way.
MK-20 SERIES OPERATION
NOTE: Read the engine instructions manual before starting saw.
(G)
Start engine by rotating Ignition
Switch to the right.
NOTE:
(H)
For Wet Cutting, open Cooling
Supply Valve. Verify proper cooling flow and adjust the water flow on the Blade to a desired amount.
(I)
Move the throttle all the way forward to "Fast" position.
Perform the cut using only enough pressure to follow the original marked line. The saw has a natural tendency to pull towards the side on which the blade is mounted. To assure straight line cutting, apply pressure to the appropriate handle. If excessive pressure is required reduce the forward speed of the saw. Driving the saw too fast while cutting may cause the front wheels to lift causing the blade to cut at uneven depths. Do not attempt to steer the saw. Sudden and severe corrections can cause the blade to be damaged or broken.
(J)
Slowly lower the Blade until the desired level is reached and begin the cut.
(K)
When the cut is complete, raise the Blade completely out of the cut by turning Depth Control Wheel counter-clockwise.
(L)
Close Cooling Supply Valve.
(M)
Move the Throttle Lever to lower blade speed.
(N)
Turn off engine by rotating
Ignition Switch to off position.
23
NOTE:
Do not turn off engine while at full throttle.
If the engine has been running hard and is hot do not shut engine off abruptly. Cool engine by removing load and allowing engine to run idle for
3 to 5 minutes.
MK-20 SERIES OPERATION
STEP CUTTING
1. Follow general instructions outlined in the section Standard Operation on page 19.
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.
DRY CUTTING
NOTE: 1. Ensure the blade you are using is clearly marked for dry cutting.
2. Check the condition of the air filter at least every four hours of operation.
Refer to Engine Manual for details.
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 and cause damage. Step cut in increments of 2 inches or less, for best results. Thinner blades are especially advantageous when cutting dry.
WARNING Dry cutting has the potential to expose you to high levels of crystalline silica.
Repeated and/or substantial inhalation can cause serious or fatal respiratory diseases including silicosis. For more information go to www.P65Warnings.
ca.gov. Employ dust controls and protection per OSHA/NIOSH/MSHA.
