BLADE INSTALLATION
1. Use the blade nut wrench (Figure 9) 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 nut and
outside blade flange . Install the cutting blade onto the inside
blade flange arbor . Re-install the outside blade flange and
blade shaft nut. Tighten securely. DO NOT over tighten.

SAW BLADES
Diamond Blades ™ are recommended for you saw. Ask your
MULTIQUIP dealer about your specific cutting application.
SAW BLADE DEFINITIONS (FIGURE 8)
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.
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.
PRE-SETUP (ELECTRIC)
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.
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.
