• Prolong motor life by preventing overheating conditions.
Undue motor wear results from frequent turns, stops
and starts, pushing objects, boating in rough water or
vegetation and boating continuously at high speed.
• Over-temperature protection is installed on the ESC to
prevent circuit damage, but cannot protect the motor
from pushing against heavy resistance.
• Lubrication is important to prevent motor damage. If your
motor gets wet, lubricate the busings supporting the motor
shaft with light duty machine oil. Failure to do so can cause
the motor shaft to seize against the motor bushings.
CAUTION:
Do not touch the motor until it has had time
to cool. It can become extremely hot when in use.
