The setpoint torque deviates from the adjustable torque when using special tool 2 405 614 . - Converting the setpoint torque into the adjustable torque:
(setpoint torque x L1): L2 =adjustable torque
L1 = length from the center of the grip to the reversible ratchet head
L2 = length from the center of the handle to the engaging of the special tool in the bolt
