Troubleshooting
Machine will not start the cycle
If you press on the foot pedal while your motors are on but the clamp isn’t coming down and the
routers aren’t coming up, then you have failure in the footswitch or the safety switch. The air
pressure may also be set too low or not attached correctly.
ƒ
Refer to the “pocket is being cut but no pilot hole” section for steps on how to reset the
air pressure.
The Safety Switch
Solution Steps:
The safety switch on the TSM-21 consists of a magnetic actuator on one side (no wires) and a
magnetic reed switch on the other (with wires). (Figure 12) When the safety buttons at the rear
of the worktop are depressed by the stock, they raise a blade inside the machine that rests in
between the safety switch and the magnet. The assembly is wired in such a way that when the
blade is raised the switch closes and electricity is allowed to flow to the foot pedal.
Figure 12
ƒ First make sure that the side of the magnet housing with the notch in it is facing the safety
blade. This ensures that the magnet is as close to the switch as possible inside the
housing.
ƒ If there is no notch in the housing, then detach it from the machine and physically inspect
it. Make sure that the magnet is turned so that it is closest to the safety blade.
ƒ If the above steps don't work then test for continuity at the switch by connecting the
ohmmeter leads to the reed switch side of the assembly.
