PJL Optima 2 Plus Instructions For Use page 2

Trouble shooting
Handpiece does not work, or makes a strange noise, after changing collets.
Usually this means that you either did not screw the collet all of the way in, or
that you still have the "Release/Secure" collet mechanism in the "Release"
mode. The collet needs to be screwed all the way in for the shaft to rotate freely.
Do not over tighten, as you may strip the collet threads on the collet when
tightening it down with the wrench (use your fingers to start it). If your collet is
in all the way, you should be able to freely rotate the bit, collet, and shaft
assembly by rotating the bit with your fingers. If only the bit rotates, and the
collet and shaft do not, then you do not have the Secure/Release mechanism in
the proper position (turn it toward the S).
The handpiece was working, but now it stopped.
Check to see that the indicator light on the power supply is on. If not, your unit
may have become unplugged, or a circuit breaker may have tripped. Check that
the handpiece coil cord is fully plugged in, and that their are no breaks or cuts in
the cord. Check to see that your "Forward / Reverse" switch is not in the center
off position, and that your On/Off speed control knob is turned to "1" or higher.
Otherwise, you may have been working the handpiece a bit too hard and tripped
the unit's internal circuit breaker, and you need to shut the main control off for
at least 30 seconds (See #5 in main instructions). If this happens a lot, you may
need to use smaller diameter bit heads (larger bit head = more torque required).
This tool is meant for doing fine detail work, not roughing out large amounts of
material with large bits (5/16" sized bit head or smaller is recommended).
If you are using a proper bit size, and not using excessive force when carving,
and you are also running the unit at lower RPMs for an extended period of time?
Then the heat sink may be over heating, and that may have caused the motor
protection circuit to trip. You can prevent that from happening, by putting the
power supply near the intake of your dust collector, or some place where the heat
sink has enough air flowing over it to cool it properly (The back panel of the
power supply unit also serves as the voltage regulator heat sink)
If all else fails!
Then give us a call, and we'll try to diagnose or fix any problems that you may be
having with your Optima 2 Plus unit. Many times it does not have to be sent in, if
it can be diagnosed over the phone, and you may be able to repair it yourself.
