TRANSMISSION SERVICE 

All Pronar T400 trailer gears are filled with SAE 90 EP gear oil (API GL-5 SAE 80W / 90).

Signs such as fresh oil stains and increased transmission noise may indicate that the oil level 

is too low. 

 

 

The  oil  level  in  the  gears  of  the  conveyor  mechanism  should  be  checked  through 
transparent sight glasses before each start of the machine. 

 
Changing the oil should be carried out at the oil working temperature, when the machine is 

running for a few minutes, then any impurities that are in the gearbox will mix with the oil and 

then be drained with it. 

 

 

Used hydraulic oil in gearboxes should be changed after the first 50 hours of operation, 
subsequent changes should be made every 500 hours. 

 
 

DANGER 

 

During  work  related  to  oil  control  and  oil  change,  use  appropriate  personal  protective 
equipment, i.e. protective clothing, footwear, gloves, glasses. Avoid oil contact with skin.
