Safety instructions, Description of motor
 Do not remove the motor from the pump as long
as there is any back pressure.
 With pressurised containers, the motor must only be taken off
when the container is depressurised.
 Before removing the motor from the pump:
Completely drain pump, flexible hose and hand nozzle.
 Power supply must include a fault current breaker.
Dirt accumulation, high humidity or material damage on
the motor housing may lead to dangerous current surges.
In case of breakage or obvious damage of the housing
immediately stop the pump and repair it.
 Non-compliance with the safety instructions may cause
injuries to the operator, pollution of the environment or
damage to the motor and the pump.
Description of motor
 Speed setting "variable with adjustment knob"
On these motors the desired speed can be variably set with an
adjustment knob (control of delivery rate).
 Thermal switch
On motors with a temperature limiter the maximum temperature
of the field winding is monitored.
If the maximum temperature is exceeded, the motor switches off.
Then the motor cannot be switched on again until after a longer
cooling time (up to 20 minutes). Repeated overloading may
damage the motor.
Overloading can result from liquids with a higher viscosity or a
higher density compared to water. If the motor switches off due
to overloading, avoid that speed.
 Overload cut-out switch
If the maximum current is exceeded, the motor switches off. After
cooling down, the motor can be restarted by pressing the on/off
button.
