PAGE 18 — SP1E16A PAVEMENT SAW • OPERATION MANUAL — REV. #0 (04/14/10)
BLADES
Saw blades, or cutting disks, are available in either an
abrasive design or as diamond blades. Either blade will
work on the SP1E16A, however, diamond blades are
recommended. Ask your dealer about your specific cutting
application.
Figure 6 highlights the components of a diamond blade.
Figure 6. Diamond Blade
1. Drive Pin Hole — A commonly located hole on the
diamond blade core that prevents operational blade
slippage between the inner & outer blade flanges
(collars). Inspect the diameter of the hole to ensure
there is no distortion, and that a snug fit develops
between the hole and drive pin.
2. 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.
WARNING
Failure to thoroughly inspect the diamond
blade for operational safety could result in
damage to the blades or the saw and may
cause injury to the user or others in the
operating area.
3. 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.
4. 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.
5. 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.
6. 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.
7. Arbor Hole — It is essential that the arbor hole
diameter properly matches the shaft arbor (1"), and
that it is free from distortions. Correct blade flanges
(collars) must be used. The inside face of the flanges
must be clean & free of debris. An out of round arbor
condition will cause damage to the blade and the saw.
8. 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.
