  Tighten the front door window glass 

  NOTE: TECHNICAL INFORMATION 
  When using special tools that extend the lever arm of the torque wrench, the setpoint torque deviates from the adjustable torque.
  NOTE: Schematic diagram is for example purposes. Some parts may differ in certain details.

• Converting the setpoint torque into the adjustable torque:

  (Setpoint torque * L1)/L2 = Torque to be set

  L1 = length from the center of the grip to the reversible ratchet head

  L2 = length from the center of the grip to the center point of the ring on the special tool

• Tighten multi-point nuts (1) on the door window glass in the front using special tool 2 360 051 B  and a torque wrench.
