Troubleshooting Basics
Good trouble shooting starts with looking at the whole machine, where every part is suspect. Then
narrowing down the view to the bad part.
Ask: Ask basic questions. For example:
• What was the Machine Trying to Do?
• What Was the Machine Trying to Do Next?
• Was the machine working before?
• Did it happen on first power up or during process?
Narrow: Narrow or determine the sequence and subsystem where the issue occurs. For example:
• Did the issue happen when door was being fed in?
• Is the router not cutting?
• Is the cut out of specification?
Note: See Table 6- 1 on page 8 for sequence and subsystem information.
Verify: Verify or analyze the subsystem assembly that is responsible for the issue. For example:
• How is the subsystem supposed to work?
• What is keeping the subsystem from working?
Note:
See“Analyze the Sub Systems” on page 6-8 for information on verifying and analyzing subsys-
tems.
Before you Adjust
Sometimes simple problems can seem to be complex issues. Before making adjustments, check
for the following common issues.
1.
Is the loaded setup correct for the current cut?
2.
Are the stops set up correctly?
3.
When did the problem first start?
• At first Start-Up?
• During the Run?
4.
When was the last calibration?
5.
Is the door true?
6.
Use Router Bit Depth Gauge (PN: 432C) to check depth of Bits
7.
Check tools for wear.
8.
Check back side of “H” blocks for sawdust build-up, which may affect depth.
