Page 20: Manual Safety Devices
Manual Safety Devices Emergency Stop Buttons The FWA-500 is equipped with a momentary stop button located on fixed end Panel. When activated, these buttons will stop the entire system of motors and activate the air brake system to halt spinning of saw blade #3.
Page 21: Pre-Start Checklist
Pre-Start Checklist In order to ensure the safety of the operator and operation of the saw, it is necessary to proceed through the following pre-check inspection procedure. Make sure the safety disconnects on the fixed end is in the “Off” position.
Page 22 4. Check all electrical leads for loose wires. Follow local electrical code procedures. CAUTION: ONLY AUTHORIZED PERSONELL SHOULD BE ALLOWED ACCESS TO THE ELECTRICAL PANELS, THE CONTENTS CONTAIN HARMFUL AND POTENTIALLY LETHAL VOLTAGE. POWER SHOULD BE SHUT OFF BEFORE ANY ELECTRICAL MAINTENANCE IS PERFORMED Mushroom E-stop Cutoff blade guard...
Page 23: Installation
Installation 1. Set the saw in place, hook up power in the fixed end cabinet (wire can enter the cabinet either in the top or bottom)  480-volt, 3 phase, 60 hertz, 60-amp wye connection  DO NOT USE CONDUIT FOR A GROUND 2.
Page 24 1/16”  If draft is needed or there is too much, adjust the pivot of the blade to have the desired 1/16”. Consult with Monet Desauw if you are unsure how to do this step.
Page 25: Calibration
It might be necessary to use a marker to draw the direction. Put a square along the 3-1/2” dimension and note how square it is.  Consult a technician at Monet Desauw Inc if the saw is out of adjustment. Saw Calibration...
Page 26 Using a framing square, measure from the bottom of the board to the BOTTOM of the cut. The measurement should be ¾”. If it is not, raise or lower the blade until it is ¾”. Recut the board until you achieve this measurement. The moveable end should look like this: Using a framing square, measure from the bottom of the board to the TOP of the cut.
Page 27 If the intersecting cuts are not in the center of the board, only adjust the front two blades, blades 2 and 4, in or out until ¾” is found. DO NOT adjust the back blades as they are already set. The FWA 500 Design: Due to the versatility of the FWA 500, each of its Saw Blade Motor Slides can be positioned for each of these 3 different types of web cuts.
Page 28: Square End Blocks
Setting the Angle of the Cut o Since Floor webs consist of 2 angles on each web end, which are 90 degrees from each other, the internal blades on each end are permanently mounted at 90 degrees from each other. o Both blades at each end will move together when angle changes are made.
Page 29: Two Piece Webs
Crank front motor slide plates away from hinged bolt stops and flip stop over on anchor plate away from motor slide plate. Crank slide plate in until crank pinion is against anchor plate. When this is done make sure the front 2 blades are not touching metal. Rear Blades: Crank 2 rear blades away from bolt stops far enough to keep the teeth from touching the webs.
Page 30 The FWA 500 has a ruled scale mounted on the front, left side of the frame. There are 2 red pointers positioned over the frame scale with a calibrated location for making square end blocks, and two & four angle webs respectively. Positioning the carriage for a desired web length is as easy as aligning the respective pointer with the frame scale.
