The solenoid for motor start is only
activated only for a short period
and then released and the band
saw motor goes back to idling again.
The solenoid for water cooling
does not work.
The Smart Set loses contact with

CONTROL/SOLUTION
Open the box and check the cable that connects to
the keypad, unplug and replace the cable. If it still
doesn't work, then it is likely that the keypad is faulty.
Move all the motor's cables to the up/down motor
controller. Activate UP/DOWN and move the control
lever back or forth. If the motor is working, then it
is likely that the motor controller for FEED is faulty.
If the motor is not working, then it is likely that the
motor is malfunctioning.
Check that the speed is not at 0. Press the + button
while FEED is activated and the control lever is
pressed forward.
Move all the motor's cables to the FEED motor
controller. Activate FEED and move the control lever
back or forth. If the motor is working, then it is likely
that the controller for UP/DOWN is faulty. If the
motor is not working, then it is likely that the motor
is malfunctioning.
Restart the Smart Set and recalibrate the sawhead.
100mm between saw blade and log bed.
Completely loosen the cable between the solenoid
and the motor, press down the enabling switch
button, and then press the start button. Manually
check that the solenoid is fully drawn to the bottom
and is held in place as long as the enabling switch
button is pressed. If the solenoid is functioning
normally without being connected to the engine,
then it is likely that the cable connecting to the
engine throttle is too tightly tensioned. If it still does
not work, check the cables, see separate instruction.
Check cables, see separate instruction.
Low battery voltage. Charge or replace the battery.
If it still does not work satisfactorily, check the cables,
see separate instruction.
Open the cover and check the cable that goes to the
display, is it properly inserted? Unplug and replace
the cable at both ends. Does pin 1 on the display
go to pin 1 on the circuit board? If not, turn one
of the contacts 180 degrees. Still not working?
Then it is likely that the cable or display is faulty.
In order for the emergency stop circuit to release
completely requires that the control lever is pushed
forward a little and then released completely.
Try starting the band saw motor now.
The engine's choke must be activated between
each use of step function.
Check data cable, see separate instruction
Communication between the control unit and motor
controls is interrupted. May be due to too low voltage
or gap in data cable.
The STEP function reaches outside the sawhead's
motion range
