serious injuries and/or death.
Using the proper blade (size and type) preserves
the blade and improves cutting and operator
efficiency, resulting in lower costs. Refer to
www.diamondproducts.com for a list of different
blade types and additional blade information.
Inspecting the Blade
Inspect each blade prior to installation and discard
all damaged blades. Inspect all blades for:
• Cracks, nicks, and dents.
• A damaged and/or deformed arbor (center
hole).
• Darkness and/or discoloration near edge of
blade.
• A deformed blade circumference.
• Segment loss and/or segment cracks.
• Core wear.
• Bending.
• Uneven side-widths.

Blade Speed
Refer to the CC6561 or CC6561-3 RPM Chart, the
blade, or the blade packaging information for the
recommended blade speeds when cutting. DO
NOT exceed the maximum recommended blade
speed. DO NOT use a blade for cutting that
requires a lower speed than the minimum blade
shaft speed.
Figure 9: CC6561 RPM Chart
Figure 10: CC6561-3 RPM Chart
Installing the Blade
WARNING
DO NOT install a blade with the
engine running.
Failure to properly secure the outer flange and
blade may cause parts to loosen or fall off of
the saw.
CAUTION
Wear gloves and be alert to the surrounding
environment when handling blades.
Use the 15/16” combination wrench that comes
with the saw when installing/removing a blade.
Apply force to the opposite end of the wrench and
tighten the bolt to 125 ft-lb (169.5 Nm) to properly
secure the outer flange and blade. This
measurement can be verified with a torque wrench.
Figure 11: Wrench
Install the blade on either the right or left side of the
saw; utilize the most appropriate side for the cutting
task. Adjust the engine governor setting, as
necessary, and install the appropriate blade shaft
sheave, blade drive belts, and flanges when
changing the blade size. Changing the blade size
requires assistance from technical support.
Contact technical support prior to running the
saw. Refer to the RPM Chart posted on the saw, or
in the Diamond Products’ Parts List for additional
information.
Remove Mounted Blade Guard
Left Side of Saw with 26” to 42” Guards
1. Remove the blade guard or insert lock pin
(attached to blade guard) through the wide rear
hinge knuckle to gain access to the blade
flanges.

2. Lift up the front half of the blade guard until the
front hinge knuckles contact this lock pin. (Note:
This prevents the front half of the guard from
contacting the engine DPF canister.) Secure by
using second lock pin located on belt guard.

1. Remove the blade shaft bolt using the wrench.
Turn the bolt clockwise (left-hand threads) on
the right side of the saw, and counterclockwise
(right-hand threads) on the left side of the saw.
2. Remove the bolt and wedge lock washer, and
carefully pull the outer flange out of the inner
flange alignment pin hole and blade shaft.
Figure 17: Blade Flanges Separated
3. Inspect the bolt, outer flange, inner flange, and
inner flange alignment pin hole for visible
damages and clean, repair, or replace or as
necessary.
4. Select the correct blade type for the cutting task
and inspect the blade for visible damages.
5. Raise the saw slightly to provide room to install
the blade.
6. Place the blade next to the inner flange. Always
point the arrow printed on the blade in the
direction of the blade shaft’s rotation when
installing the blade.
7. Align and fit the outer flange alignment pin and
shaft through the blade holes, and into the
blade shaft and inner flange alignment pin hole.
Figure 18: Inserting the Outer Flange
8. Slightly rotate the outer flange and blade
backward to eliminate backlash (looseness)
between parts.
9. Place the wedge lock washer onto the blade
shaft bolt and insert the bolt into the blade
shaft.
10. Tighten the bolt by hand as much as possible,
and slowly lower the blade until it just touches
the ground’s surface.
11. Tighten the bolt, using the wrench, to 125 ft-lb
(169.5 Nm) to properly secure the outer flange
and blade. This measurement can be verified
with a torque wrench.
Figure 19: Tightening the Bolt
12. Reattach the blade guard or pivot the front of
the guard down and over the blade to secure.
Removing the Blade
CAUTION
Always let the blade cool prior to
removing or replacing blades when
dry cutting.
1. Remove the blade guard or pivot the front of the
guard 180° (fully upward, secure with pin) to
gain access to the blade flanges.
2. Slowly lower the blade until it just touches the
ground’s surface.
3. Remove the blade shaft bolt and wedge lock
washer from the blade shaft.
4. Carefully pull the outer flange out of the inner
flange alignment pin hole and blade shaft, and
then remove the blade. Place the blade in the
appropriate storage location.
