MOTOR PROTECTION FUNCTION
This machine has a circuit that stops the ma-
chine when the motor becomes hot.
If the motor stops, stop using the machine, turn
off the power switch, wait until the motor cools
down, and then start the work again.
•
Notification that the machine stopped be-
cause of motor high temperature
The buzzer sounds and the two at both ends of
the three lamps on the control box blink in red
and the center one goes off.
8. If a twig is caught in blades
If a twig is caught in the blades (cannot be cut by
the cutting action), release the trigger. Releasing
the trigger moves the blades in the opening di-
rection.
If the twig is still caught in the blades after releas-
ing the trigger, do not move the machine to the
sides but move it slowly in up and down with the
trigger released to free the twig from the blades.
To reuse the machine after removing the twig,
release the switch lever again. After that, the ma-
chine can be used as normal.
