MQ MP2 MASONRY SAW — OPERATION MANUAL — REV. #2 (3/12/13) — PAGE 21
Blade Installation
1. Use the blade bolt wrench (Figure 10) supplied with the
saw to install the cutting blade.
2. Ensure the capacity of the blade guard matches the
diameter of your cutting blade.
3. Using the blade nut wrench, remove the blade shaft bolt
and outside blade flange. Install the cutting blade onto
the inside blade flange arbor. Re-install the outside blade
flange and blade shaft bolt. Tighten securely. DO NOT over
tighten.
Figure 9. Diamond Blade
Saw Blades
Diamondback Diamond Blades ™ are recommended for
your saw. Ask your MQ dealer about your specific cutting
application.
Saw Blade Definitions (Figure 9)
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. 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.
3. Directional Arrow - Ensure that the blade is oriented
properly on the blade shaft 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 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
or injury to the user or others in the operating area.
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.

5. Specifications - Ensure that the blade specifications,
size, and diameter properly match up to sawing
operations. Utilizing a 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 blade, and that it is free from
distortion. 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
maximum RPM is dangerous and may cause poor
performance and may damage the blade.
