Gear Box and Drive Wheels
To use the drive wheel, either the outer fast loading handle or inner slow loading handle needs to be pulled
out of the recess (see figure 16). Once out the handles will lock into position (see figure 17).
To fold away, the handle must be pulled towards the user and angled away back into the seated position.

WARNING:
Handle Use
The two drive wheels offer different speeds of operation.
The outer drive wheel is geared to load the torque wrench 4.5 times faster than the inner wheel. This is
•
suitable for when large torque wrench movements are required, for example, when moving the torque
wrench up to the reaction post.
•
The inner wheel offers slower motion. This allows more precise adjustment and makes it easier to apply
high torque values.
