Possible problem and troubleshooting

POSSIBLE PROBLEMS AND TROUBLESHOOTING
The harvesting rod does not work:
The generator does not supply power. Generators not equipped with voltmeter and ammeter can cause damage to the harvester because they supply current of higher or lower voltage.
The injection pins are not properly attached.
Cut or damaged cord.
On-off switch is broken
Worn out or destroyed carbons.
A foreign matter has entered the motor from the cooling air inlet

The harvesting rod works slowly:
Low generator voltage (below 12V) or uncharged battery.
Worn out carbons.
Increased friction (caused by the use of non original parts etc)
The motor works but the head does not move:
Unscrewed or cut transmission shaft.
