EXCEL SERIES BLADES
The Excel Series of diamond blades have been designed specically for the Soff-Cut Ultra Early Entry dry cutting system of
green concrete. These specialty blades are designed to increase speed and life while cutting a wide range of aggregates.
Choose the correct specication of diamond blade for your area as follows:
Red Excel Series 3000 XL5-3000A-X50 Hard aggregate, medium abrasive sand
Yellow Excel Series 5000 XL5-5000A-X50 Medium hard to soft aggregate, abrasive sand
(Red Blade also available in 0.225” (5.72mm) widths)
Step 1
Remove the blade cover (A) by turning the two metal knobs
counter-clockwise. While holding the spindle lock button (B),
remove the blade bolt (C) by turning it counter-clockwise using
a 1/2” wrench. Remove the blade ange (D). Inspect the blade
(E) for any damage.
WARNING
Do not use any blade that has cracks, nicks, aws or
a damaged arbor. Make sure the blade is marked with
a maximum operating speed greater than 11,000 rpm.
Use only dry cutting concrete diamond blades.
Step 2
Match the blade tri-arbor (E) to the blade shaft arbor (F) and
install the blade rmly against the rear ange (F). Insure the
blade is installed on the tri-arbor correctly. Match the female tri-
arbor of the blade ange with the tri-arbor blade shaft and in-
stall the blade bolt turning clockwise. Be sure the outer ange
is fully seated and rmly holding the diamond blade in position.
Step 3
Install a new skid plate (G) by sliding the front into the angled
slot of the lower blade guard (H) and rmly against the depth
stop washer (I). Push the rear of the skid plate up into the
threaded stud at the rear of the lower guard and screw on the
skid stop washer (J). Hand tighten only.
Step 4
Raise the lower guard and check that the blade does not con-
tact the skid plate. When replacing a worn blade, thoroughly
clean the concrete from the blade guard (upper and lower
guard) and blade cover before installing the new blade.
A new skid plate is included with every new blade. Make sure
to remove and discard the old skid plate and replace it with a
new skid plate every time the blade is replaced.
NOTE:
The patented skid plate is the most important part of the
Soff-Cut Ultra Early Entry system. If it is bent, twisted or
damaged, spalling and raveling of a cut may result. Store
skid plates carefully and install them properly. Install a
new skid plate with each new blade. Never re-use skid
plates.
