between 5L3 [red wire] and the red wire beside 2T1. To gain access to
the terminals, you will have to remove the switch plate from the front of
the machine. This circuit is a loop that has the foot brake, stop switch and
door switch. It is designed to be fail-safe, and any switch that is not
functioning or set correctly will cause the machine not to start. If there is
no continuity you will have to trace the switch that is open or faulty and
correct the fault.
9. Check that you have the correct power 220V not 110V
10. Check that the earth wire is wired correctly.
The machine will not stop
This is a very rare occurrence as the machine is designed to be fail-safe. If it
should occur and you cannot fix the fault, seek professional assistance. The
machine must be disconnected from the power and never run until the fault has
been rectified.
1. Stop switch faulty. Replace the stop switch.
2. Internal breaker faulty. Replace the breaker.
Motor tries to start but will not turn
1. With the power disconnected from the machine open the doors and try to
turn the wheel by hand. If the wheel is not turning, check the reason for
the jamming. Typical reasons are: guides too tight, wood jammed in the
wheel.
2. Capacitor faulty. Replace the capacitor.
3. Motor faulty. Replace the motor.
Motor overheats
The motor is designed to run very hot, but should it overheat it has an internal
terminal overload protector that will shut it down until the motor has cooled
down and then it will reset automatically. If the motor overheats, wait until it
has cooled down and restart. If the motor shuts down constantly, instantly
check for the reason. Typical reasons are dull blade, over feeding the wood,
motor cooling fan clogged or faulty, motor cooling fins clogged and excessive
ambient temperature.
Squeaking noise
1. Check that the motor cooling fan is not contacting the fan cover.
2. Check the bearings.
3. Check the drive belt.
4. Check that the guides are adjusted correctly.
Upper guide shaft is tight or loose
1. Clean and lubricate.
