ANTI WIND-UP RATCHET

Purpose of the Anti Wind-Up Ratchet (AWUR)
Most multipliers with ratios of 15:1 and over are fitted with an anti wind-up ratchet. The multiplier can be
thought of as a spring which must be fully wound before any tightening/untightening work can be applied to
the bolt.
The AWUR ensures that the 'spring' stays wound and that any further torque input to the multiplier is applied
directly to the bolt.
Familiarise yourself with the tool by initially applying low torques and removing wind-up.
There are two different types of AWUR that your HandTorque
below in Figure 8. The AWUR shown on the left side of the page requires a hexagon key to lock in to the
neutral position. The AWUR on the right side of the page will automatically lock into the neutral position
without the need for a hexagon key.

Operation of the Anti Wind-Up Ratchet

Please Read Carefully
1. Position the 'ratchet direction selector' for the appropriate direction of operation:
Test direction of rotation and ensure that the ratchet operates freely.
Or CW = Clockwise
Or CCW = Counter-Clockwise
Or N = Neutral
WARNING:
Clockwise Operation / Bolt Tightening
Neutral Position:
Centralise the 'ratchet direction selector'.
Depending on model type this may need locking
into position using a hexagon key. Check that the
input square rotates freely in both directions before
operation.
Counter-Clockwise Operation /
Bolt Loosening
