WARNING
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 and
• Arsenic and chromium, from chemically treated lumber
For further information, consult the following sources: http://www.osha-slc.gov/sltc/silicarystalline/index.html
http://www.oehha.org/prop65/out_of_date/6022kLstA.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 filter out microscopic particles.

SAFETY
ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS:
In order to prevent potential electrical shock and injury, the following electrical safety precautions and symbols should be followed at all times!
!
WARNING
In case of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipmentgrounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
• Do not modify the plug provided – if it will not fit the outlet; have the proper outlet installed by a qualified electrician
• Improper connections of the equipment-grounding conductor can result in a risk of electric shock.
The equipment-grounding conductor is the insulated conductor that has an outer surface that is green, with or without yellow stripes. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal
• Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded
• Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool’s plug
• Repair or replace a damaged or worn cord immediately
!
WARNING
This tool is intended for use on a circuit that has an outlet that looks like the one shown in Sketch A of
Figure 1. The tool has a grounding plug that looks like the plug illustrated in Sketch A of FIGURE 1. A temporary adapter, which looks like the adapter illustrated in sketches B and C, may be used to connect this plug to a 2-pole receptacle as shown in Sketch B, if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter, must be connected to a permanent ground such as a properly grounded outlet box.
NOTE:
Use of a temporary adapter is not permitted in Canada
!
FIGURE 1
WARNING
To reduce the risk of electrocution, keep all connections dry and off the ground.

MAINTENANCE AND TROUBLESHOOTING
BLADE DRESSING
Like most cutting instruments, a Diamond Blade performs best when it is dressed. Over time and use, diamonds on the outer edge will become smooth or “glazed” over. This will reduce grinding efficiency and may cause the blade to “wander” or bend, giving the illusion of an alignment problem. When this occurs, the blade will need to be dressed. The diamond blade can be dressed using the MK Dressing Stick (part number 152792) and by following the steps below.
1. Set up the PX-3 for operation.
2. Position the Back Stop to accommodate the Dressing Stick.
3. Hold the Dressing Stick in position and depress the Trigger to start. Lock if desired.
4. Lower the Cutting Head while pushing the Dressing Stick into the Blade.
!
CAUTION
Allow the Blade to stop moving before removing work
5. Repeat the cut stroke eight (8) times.
6. When the Blade is dressed, release the Trigger Switch and raise the Cutting Head. Allow Blade to stop
moving before removing the Dressing Stick.

THEORY
THEORY OF DIAMOND BLADES
Diamond blades do not really cut; they grind the material through friction. Diamond crystals, often visible at the leading edge and sides of the rim/segment, remove material by scratching out particles of hard, dense materials, or by knocking out larger particles of loosely bonded abrasive material.
This process eventually cracks or fractures the diamond particle, breaking it down into smaller pieces. As a result, a diamond blade for cutting soft, abrasive material must have a hard metal matrix composition to resist this erosion long enough for the exposed diamonds to be properly utilized.
Conversely, a blade for cutting a hard, non-abrasive material must have a soft bond to ensure that it will erode and expose the diamonds embedded in the matrix. These simple principles are the foundation of “controlled bond erosion”.
26
Types of Cutting
There are two basic types of cutting-Dry or Wet; however, the PX-3 is designed only for Dry Cutting. The choice of which type of blade to use depends on:
• The requirements of the job
• The machine/tool utilizing the diamond blade
• The preference of the operator
In the case of DRY cutting, the overwhelming popularity and quantity of hand-held saws and the flexible nature of MK Diamond blades to professionally handle most ceramic, masonry, stone and concrete materials, make the
DRY cutting blade a very attractive tool. When using a DRY blade, the user must be aware of distinct operating practices to ensure optimum performance. DRY cutting blades require sufficient airflow about the blade to prevent overheating of the steel core. This is best accomplished by shallow, intermittent cuts of the material with periods of “free-spinning” (for several seconds) between each cut, to maximize the cooling process.
