E. Slip control
Slip percent can be programmed. Slip control system is con-
trolled with a selector which has six different positions. In the
first position (0), the slip control is not in function. Other posi-
tions (1 ---5) determine the lift movement. In addition, the sys-
tem has a buzzer which gives a signal if the set slip percent
is exceeded in position control mode (draft control selector in
position P).
