INSPECTION
BLADE
Use the following type of blade:
Steel Core Segmented or
Diamond Rim Cutting Wheel.
Any other type of blade should not to be used. See Table
5 for specific blade usage for material.

WARNING
Failure to thoroughly inspect the
diamond blade for operational safety
could result in damage to the blade,
the saw, and may cause injury to the
user or others in the operating area. All
damaged blades must be discarded.
NOTICE
Adhere to the blade manufacturer's recommendations
on handling, storage, and safe usage of blades.

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.
3.
Directional Arrow
— Check to ensure that the blade is
oriented properly on the blade shaft for sawing. Reference
the directional arrow in 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, 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.
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 blade, 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.
DO NOT
use blades
rated at a lower rotational speed than the rated RPM of the
saw (6000 RPM). Exceeding the MAX RPM is dangerous
and may cause poor performance and may damage the
blade. All blades must be designed to meet or exceed the
maximum spindle RPM.
