The drive card is the top one nearest the front og the truck and the pots are as follows.
From the left as look into the truck from the rear.
GB=travel speed limitation
HZ=rate of acceleration
BS=regen current braking
FS=Current limit
RS=Plug braking current
Anti clockwise to increase and clockwise to decrease.

The pump card adjustments againn starting from the left are as follows.
4=4th service speed
3=3rd service speed
2=Tilt speed
1=Lift speed
SK=Hydraulic start speed adjustment. Turen this pot clockwise until the pump motor starts, then turn anti clockwise until it stops, then turn 1 more turn in that direction.

Hope this helps.
