Problem Possible cause Troubleshooting
Motor fails to develop full
power (output of motor
decreases rapidly with
decrease in voltage at
motor terminals).
1. Power line overloaded with
lights, appliances, and other
motors.
2. Undersized wires or circuits
too long.
1. Reduce load on power line.
2. Increase wire sizes or reduce length of the
circuit.
Motor overheats. 1. Motor thermal protector
rejected
2. Air circulation through the
motor restricted.
1. Wait for the motor temperature cold down;
then motor thermal protector will re-set
automatically
2. Clean out motor to provide normal air
circula-tion.
Motor stalls (resulting in
blown fuses or tripped
circuit).
1. Short circuit in motor or loose
con-nections.
2. Low voltage.
3. Incorrect fuses or circuit
breakers in power line.
4. Ampere setting too low,
conductor overloaded.
1. Repair loose or shorted terminals, or worn
insulation on motor.
2. Correct the low voltage conditions.
3. Install correct fuses or circuit breakers.
4. Reset the ampere value correctly by checking
the machine information from the name plate.
Main blade runs
backwards.
1. Two of the power wires are
reversed.
1. Exchange wires L1 & L3 in the terminal box.
Blade makes a squealing
noise on start-up.
1. Belt worn out. 1. Replace belt.
Workpiece jammed when
feeding forward.
1. Blunt saw blade.
2. Riving knife thickness does
not match the saw blade used.
1. Fit a sharp saw blade
2. Fit the correct riving knife; it must thicker
than the main saw blade (or at least the same) .
The finished size of the
cut workpiece does not
match the cutting width
set on the rip fence.
1. Dimension scale for cutting
widths is misadjusted.
2. Incorrect scale position.
1. Reset the dimension scale to correct size.
2. Reset scale position. Cut a workpiece on the
rip fence, precisely measure the cut width and
position the scale to match workpiece size.
