The "i" means its ac so inverter prob bolted on top of drive axle. This could be done or even the contacts between inverter and axle

R70 is engine , generator hybrid not like the full electric R60 with the inmotion inverters, rx70 has an inverter but sure the r70 is field exited by main controller. Id do checks as above also service address 150 if i mind right toggles between customer error display and engineer error display.

Id check engine speed sensor located top of bell housing this can cause no drive, also alternator fault can cause no drive

Just check the traction and hydraulic inverters if the green light LED is on.. If not or the LED light is off the inverter is defective. I am repairing the inverters for R60-30i still forklift by changing the defective capacitors.

when I ised to work for still I used to see parameters change on their own to double pedal type,
also check foot controller plug connection and if its a single pot accelerator then the drive switch to striker wear can increase causing to not switch can be cajouled with a screwdriver lol.

It's me again :)
I haven't fix the problem with our forklift

Can somebody send me service/repair manual, I heard that the connection between inverter and the pc need to be established again with some passwords.
Can somebody tell me those default passwords and how to enter them, am really confused because there is no error message on the display.

Please somebody help me :)
Thanks
