BLADES
Blade Components
Diamond blades are recommended for your saw. Ask your
Multiquip dealer about your specific cutting application.
Figure 8 highlights the components of a diamond blade.
Figure 8. Diamond Blade
1. Stress Relief Holes (Gullets) — Check the steel core
for cracks that may have propagated from the slots
and/or gullets. Cracks indicate extreme fatigue failure
and if sawing continues, catastrophic failure will occur.
2. Edge of the Steel Core — Check the diameter edge for
discoloration (blue oxidation) indicating an overheating
condition caused by insufficient cooling water/air.
Overheating of blades may lead to loss of core tension
and/or increase the possibility for blade failure. Check
to make sure the steel core’s width is uniform about
the rim of the blade, and not succumbing to an “under
cutting” condition brought about by highly abrasive
material or improper under cutting core protection.
WARNING
Failure to thoroughly inspect the blade for
operational safety could result in damage to
the blades or the saw and may cause serious
injury to the user or others in the operating
area. Inspect the blade flanges and shaft for
damage before installing the blade.

3. Directional Arrow — Check to ensure that the blade is
oriented properly on the spindle for sawing. Reference the
directional arrow on the blade and place it so the direction
of rotation “downcuts” with the turn of the shaft.
4. Diamond Segment or Rim — Ensure that there are
no cracks, dings, or missing portions of the diamond
segment/rim. DO NOT use a blade that is missing
a segment or a portion of the rim. Damaged and/or
missing segments/rims may cause damage to your saw
and injury to the user or others in the operating area.
5. Specifications — Ensure that the blade specifications,
size, and diameter properly match up to the sawing
operation. Wet blades must have water to act as a coolant.
Utilizing a diamond blade not matched properly to the task
may result in poor performance and/or blade damage.
6. Arbor Hole — It is essential that the arbor hole
diameter properly matches the shaft arbor, and that it
is free from distortions. Correct blade flanges (collars)
must be used. The inside face of the flanges must be
clean and free of debris. An out of round arbor condition
will cause damage to the blade and the saw.
7. MAX RPM — This RPM reference is the maximum safe
operating speed for the blade selected. NEVER exceed
the max RPM on the diamond blade. Exceeding the MAX
RPM is dangerous, and may cause poor performance
and may damage the blade. All blades used must be
designed for the maximum spindle RPM.
Cutting Depth
The recommended cutting depth is 1/4" (6 mm) below the
cutting table surface. To adjust the cutting depth, loosen the
cutting head adjustment knob so that the blade is 1/4" below
the top of the cutting table's surface. See Table 4 to determine
cutting depth by blade diameter.
WARNING
Setting the blade too low may damage the cutting table
and if set too high, the blade may grab the material
being cut, causing damage and possibly injury.
