Connecting the geared motor (electric motor with gearbox)
@ 39\mod_125 9315210400_6. doc @ 141472 @
Before connecting
check that the power supply is correct for the motor.
Be sure to follow the cable layout diagram on the inside of the motor terminal box cover.
note that the PTC temperature sensor of the geared motor must be connected to the terminals
provided on the pump control, to a PTC actuation unit or to a variable-frequency drive with a PTC
input (each available as an option).
install a repair switch near to the machine (recommendation).
Before start-up or long-term storage
the seal in the bleed screw must be removed in order to prevent excessive pressure build-up in the
gearbox and thus leaks (see the accompanying documentation "Operating instructions – geared
motor”).

• Leakages can occur due to seal faults.
• Wear protective goggles.
On injuries with hydraulic oil, seek out a doctor immediately!

Hydraulic motors and hydraulic hose lines
• Before connecting hydraulic hoses, read and follow the manufacturer’s specifications for hydraulic
motors.
• Observe the permissible hydraulic pressure and the permissible delivery rate.
• Replace hydraulic hose lines that show signs of damage or ageing. Only use genuine Vogelsang
hydraulic hose lines of the manufacturer.
• The date of manufacture of the hydraulic hose line is displayed on the pressing component of the
connector. The period of usage for the hydraulic hose line should not exceed 6 years (although 5
years is recommended), including a possible storage period of no more than 2 years.
