BLADE AND SKID PLATE INSTALLATION

Step 1

Turn the key switch (located on the engine) to the “ON” posi- tion. Press the rocker switch located in the right handle bar to raise the saw to its full height. Turn the key to the “OFF” posi- tion.

Step 2

Remove the blade block cover (A) by turning the two locking knobs counter-clockwise. Insert the blade wrench supplied with the saw on the blade shaft bolt (C) on the end of the blade shaft in the blade block (I). Rotate the blade shaft counter- clockwise with wrench on the blade shaft bolt (C) while push- ing in on the blade shaft locking pin (J) located on the front of the saw frame. The locking pin will drop in the blade shaft and prevent the shaft from rotating.

Step 3

Remove the blade shaft bolt by continuing to turn the bolt counter-clockwise. Remove the outer arbor washer or flange

(D).

WARNING

Inspect the blade (K) for any damage. Do not use any blade that has cracks, nicks, flaws or a damaged arbor. Make sure the blade is marked with a maximum operat- ing speed greater than 3500 rpm.

Step 4

Match the blade tri-arbor 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 outer washer or flange with the blade shaft and install the blade shaft bolt turning clockwise while holding the locking pin in. Be sure the outer flange is fully seated and firmly holding the diamond blade in position.

Step 5

Install a new skid plate (G) by hooking the front on the front blade block shaft pin. Connect the rear blade block shaft and the rear of the skid plate by installing the locking pin (B).

Step 6

Install the blade cover by turning the two knobs and tighten un- til fully seated against the blade block. Lift the front and rear of the skid plate to insure the blade slides through the skid plate freely.

Step 7

Insure the lexan shields (E & H) move freely up and down. When replacing a worn blade, thoroughly clean the concrete from blade block and blade cover before installing the new blade. Discard the old skid plate and replace it with a new skid plate.

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.
