MK-3000 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.

SAW GUIDE ALIGNMENT AND ADJUSTMENT
OPERATION
Engagement
Handle
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.
REAR: With the blade centered over the line and the saw frame parallel to the line, loose the pointer and adjust up or down and ensure that it touches the line.
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. Secure hardware.

MANEUVERNG 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.
ENGAGING THE DRIVE UNIT
This saw is driven by a hydrostatic transmission. To engage the transmission, PULL the Engagement
Handle up and turn to either direction to lock (Figure 14). To disengage the transmission, twist the
Engagement Handle and PUSH down.
NOTICE
DO NOT engage the unit unless directional FNR Handle (Figure 14) is on NEUTRAL.
SPEED CONTROL-LEVER USE AND ADJUSTMENT
Move the saw forward by pushing the lever away from the operator and move the saw in reverse by pulling the lever toward the operator. The further you push this lever, the faster the saw travels.
22
WATER HOOK UP
Prior to starting the engine, you should hook up the water hose to the Water Inlet (Figure 16) and visually inspect it to make sure that water is flowing to the blade. Hook up the hose to the the unit and turn on the water source. Open the water valve. Next, lift the front of the blade guard and visually inspect the make sure water is flowing out of each of the tubes. If either of the holes is blocked, flush impurities from the tube.
NOTICE
Water flow volume can be metered by opening the water valve partially (Figure 17).

DEPTH INDICATOR
The saw is equipped with a Depth Indicator. The Depth Indicator (Figure 18) 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 knob to 0.

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.
23
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 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, 5W-
20 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.
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 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 (Figure 19).
Remove plug (Oil Gearbox Plug) and fill transmission gearbox with 80-90 SAE Gear Oil to lower edge of fill hole.
