The product stops after only a while
• If the product overloads, the overload protection
engages and stops the motor.
• Decrease the load. The lower hole is for a higher
handlebar and increased grind pressure. The top
hole is for a lower handlebar and decreased grind
pressure.
• The product restarts after approximately a minute,
when the temperature of the motor is decreased to
usual level.
• Make sure that the extension cables are not too
short.
The product stops during startup
Correct voltage supply is necessary for a good motor
performance. Too long extension cables and/or a too
small gage decreases the power of the motor during
operation.
• If the motor overloads, the overload lamp comes on.
Wait 2 minutes and try again. When this does not
help, speak to an approved service workshop.
• Make sure that the extension cables are not too
short.
