8.0 TROUBLE SHOOTING GUIDE
8.1 ELECTRICAL TROUBLE SHOOTING
1. THE MOTOR WILL NOT RUN:
A. Some models have a lock-out switch in the base of the saw. If your saw has this option, make sure
that it is in the ON position.
B. On manual and power vise machines, the Hi-Low switch must be in either the Hi or the Low
position for the trigger switch to work.
C. On machines equipped with the power down feed option, the HI-LOW switch must be turned to
either the HI or LOW position and the foot switch depressed to start the motor.
D. Also, check the supply voltage to the saw to make sure that it is the same as the motor voltage. If
the supply voltage is correct, the switch energizes and the motor still will not run, contact your
local dealer or the factory.
2. THE SAW MOTOR RUNS BUT DOES NOT HAVE ADEQUATE POWER:
A. Make sure that the supply voltage and phase correspond to the saw motor’s voltage and phase.
B. Disconnect the machine from the power source and check for any loose or disconnected wires.
C. The supply lines to the machine must be of adequate size to handle the load. For recommended
sizes and lengths, SEE SECTION 4.4.
D. The worm gears in the head may be damaged. With the power to the machine disconnected, check
the blade spindle for any free travel. If free play is present, drain the oil from the head and
remove the motor. Check both worm gears for wear and replace, if necessary. We recommend
replacing the worm gears as a set, if either shows wear.
For instructions, REFER TO SECTION 8.4.
