Drive Test
The drive test measures how much force it takes to move the positioner. This can help identify and locate mechanical issues.
To run the drive test:
1. Access the Debug menu (
) and press
repeatedly until the Drv Test screen is displayed.
2. Ensure the area is clear. Press
when ready.
•
The pusher will move slowly to the far limit, in to the minimum, and back out to the far limit.
•
During the drive test, the top row will show the current position (P) and the current drive (Drv). Watch the drive
value for large (>15%) spikes or sags that could indicate the location of mechanical irregularities.
3. When the drive test is finished, the peak drive in both directions is displayed (MxP and MxN), along with
the corresponding positions (P).
•
MxP is the maximum drive away from the tool.
•
MxN is the maximum drive toward the tool.
Run the drive test quarterly, and keep a log of the peak drive values and positions. If the peak drive changes more than 15% from
original values, it should be investigated.
Saw Belt Tension and Replacement
The pictured bolt on the motor mount is used to adjust belt tension.
To adjust belt tension:
1. Set the mitering angle to 45° right of zero.
2. Turn the saw off.
3. Disconnect power and air.
4. Open the left cabinet base door.
5. Loosen the fix nut (above the plate).
6. Use the adjustment nut (below the plate) to change the belt tension.
•
Belt tension increases as the adjustment nut moves up the bolt.
•
Do not completely remove the adjustment nut.
•
When the belt is properly tensioned, there is < 0.5 inches (12.7 mm) of flex
in the belts at the center point between pulleys.
•
Increase the belt tension if the saw squeals on startup.
7. Tighten the fix nut (above the plate) once adjustment is complete.
Removing and replacing belts:
1. Drastically reduce the belt tension.
•
The plate won’t always move with the adjustment nut. Squeeze the belts to force it along.
2. Thread the outermost belt over the pulley lip and then rotate the pulley to remove it.
3. Repeat this process to move belts between pulley grooves and to install the replacement belt.
4. Re-tension the belts and tighten the fix nut before closing the cabinet.
Warning: During the drive test, the machine must move to both limits.
Be sure the path is clear to prevent collisions.
