CLUTCH ADJUSTMENT

To adjust the clutch on these Angle Wrenches, proceed as follows:
1.

Rotate the Clutch Adjusting Hole Cover (52) until the slot in the Cover aligns with a corresponding slot in the Motor
Housing Assembly (34).

2.

Using a wrench on the square drive spindle or hex bit insert, rotate the output spindle until the half circle notch on the
motor end of the Clutch Adjusting Nut Lock (69) is visible in the slot.

3.

Insert a #1 Phillips head screwdriver into the notch of the Nut Lock and one of the notches in the Clutch Adjusting Nut
(68).  Insert the screwdriver far enough to create a gap between the Nut Lock and Adjusting Nut.

4.

Turn the screwdriver clockwise (as you would to tighten a screw) to increase the the clutch torque or counterclockwise to
decrease the clutch torque.

5.

Final clutch adjustment should be set on the job.

GRIP ADJUSTMENT

The Handle (1) of the Angle Wrench has an Adjustable Grip (9) which permits individual operators to select one of three
handle thickness positions.  Operators with large hands can select the bulkiest position and operators with small hands can
select the smallest size.  To adjust the Grip, proceed as follows:

1.

Grasp the grooved ends of the Adjustable Grip Latch (10), and spreading the ends slightly, raise the Latch to its upper-
most position.  (Refer to TPD1255).
