Clutch Adjustment
For Models 7RLL2C6-EU, 7RLL3C6-EU and 7RLM3C6-EU,
incorporate an adjustable clutch that
can be externally adjusted within a certain range to ratchet when a
predetermined torque has been delivered.
To increase the adjustable torque range, two Clutch Springs are offered.
The Heavy Clutch Spring (color-coded green for identification) is suitable for the
majority of applications since it will give precise adjustment from approximately 45 to 90 in-lb
(5.0 to 10.2 Nm) torque.
The Light Clutch Spring (color-coded black)
is for applications ranging from approximately
15 to 65 in-lb (1.7 to 7.6 Nm).
WARNING
Disconnect the air supply from the Tool before proceeding.
To adjust the Clutch, proceed as follows.
1. Rotate the Adjusting Hole Cover on the Clutch Housing to expose the adjusting hole.
2. Insert a 1/4” Allen Wrench into the recess in the Bit Holder or grasp the square drive of the
Socket Adapter Spindle Assembly with an adjustable wrench. Rotate the wrench until one of
the radial holes in the Clutch Adjusting Nut is visible through the slot in the Clutch Housing.
Insert the Clutch Sprag Key into the elongated slot in the Clutch Housing and into the hole in
the Adjusting Nut to sprag the Nut against rotation.
WARNING
The clutch, when equipped with the Heavy Spring, can be set beyond the torque
capacity of the tool in which case the tool will stall before the Clutch ratches. Do not
adjust the Clutch beyond the torque capacity of the tool.
3. Grasp the tool firmly in one hand and rotate the output end of the Angle Head. Rotating the
output end clockwise when facing the front increases the compression on the Clutch Spring
and raises the torque at which the clutch will ratchet.
NOTICE
The most satisfactory adjustment is usually obtained by using the tool on the actual
application, and increasing or decreasing the delivered torque until the desired setting
is reached. In any event, it is recommended that the final adjustment be made by gradual
progression.
