MK Diamond MK-470 - Manual (Page 7)

Do not attempt to cut pieces too small to hold by hand outside the blade guard. Avoid awkward hand positions where a sudden
slip could cause a hand or fingers to come in contact with the blade. When cutting any material, make sure it is fully supported.
Hold workpiece firmly against the fence. Only feed the material as fast as the blade is able to affectively cut. DO NOT FORCE THE
MATERIAL INTO BLADE!

Periodic maintenance your MK-470 allows for long life and tro u b l e - f ree operation. The cutting residue that the saw generates could be
considerable. A cleaning, lubrication and maintenance schedule should be maintained.
R e q u i red maintenance practices include:
• Clean the saw with fresh water after every use.
• Pump clean/fresh water for (1) minute through the water pump and blade guard assembly to safeguard against slurry build-up and
c l o g g i n g .
• Inspect the diamond blade for its overall integrity. Check the rim or segment rim for wear or damage.
• Inspect the wear of the electric motor’s (2) carbon/graphite brushes regularly. The brushes are easily accessible by removing
the brush caps with a flat end screw driver from the square top of the motor. Pull the brushes from their holder and change
them when approximately 1/4" of the brush remains. Use only authorized MK parts.
For your safety, turn ON/OFF switch “OFF” and unplug saw from the power source before performing any maintenance or cleaning.
If the power cord becomes damaged in any way, replace it immediately with the approved cord. When cleaning the saw, DO NOT
let the motor come in direct contact with water. If excessive moisture is introduced to the motor electrical shock could occur and
can cause damage to the internal parts.
DO NOT Service the motor’s internal parts yourself. Contact an authorized MK Service Center, or MK Diamond’s Factory Service
Center for technical support and parts information 1-800-474-5594 for help in solving any problems.
Use only MK DIAMOND authorized brushes to ensure compatibility and avoid motor damage.
For best results use only MK DIAMOND blades.

Rip cutting is the term used to describe cutting the material flat on the conveyor table. When cutting the
material on the square, position the rip guide to the desired cutting dimension, and tighten the thumb screw
to secure it in place. Firmly hold the material against the conveyor table back stop and the rip guide while
cutting. When cutting diagonally, position the material using the conveyor table back stop and the optional dual
45° flat angle guide. For cutting materials at other angles, use the 0-90° protractor to align material to the desire d
angle. (See optional accessories, page 5.)
Do not attempt to cut pieces too small to hold by hand outside the blade guard. Avoid awkward hand positions
where a sudden slip could cause a hand to move into the blade. When cutting a large piece of material, make
sure it is fully supported. Hold workpiece firmly against conveyor table, back stop and guide. Only feed the
material fast enough for the blade to cut. DO NOT FORCE.

The markings on the conveyor table back stop are used to aid in cutting tile to particular dimensions. The scale on
the top of the back stop is used for setting the rip guide’s diamond window indicator relative to the exact distance
from the diamond blade to the edge of the rip guide. You must first measure the tile for the cut to act as the
standard, and then use the rip guide & table markings to assist in additional cuts.
