BLADE AND SKID PLATE INSTALLATION

WARNING

Disconnect the unit from the power source before making any adjustments or changing blade and skid plate.

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 flange (D). Inspect the blade

(E) for any damage.

WARNING

Do not use any blade that has cracks, nicks, flaws 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 firmly against the rear flange (F). Insure the blade is installed on the tri-arbor correctly. Match the female tri- arbor of the blade flange with the tri-arbor blade shaft and in- stall the blade bolt turning clockwise. Be sure the outer flange is fully seated and firmly 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 firmly 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.
