-- Position the Clamping Pliers VAG1682A -1- as shown in illustration. When doing this, make sure that edges of clamping pliers are seated in corners -arrows- of clamp.

-- Tighten the clamp by turning the spindle using a torque wrench -2- (do not tilt the pliers).

• Use torque wrench -2- with 5 to 50 Nm range (for example, Torque Wrench 1331 5-50Nm VAG1331).
• Make sure the spindle threads on the pliers -1- move freely. Grease with MoS₂ grease if necessary.
• If the thread is tight, for example, dirty, the required tensioning force for the hose clamp will not be achieved in spite of correct torque specification settings.
