Installation and Lubrication
Size air supply line to ensure tool’s maximum operating pressure (PMAX) at tool inlet. Drain
condensate from valve(s) at low point(s) of piping, air filter and compressor tank daily. Install
a properly sized Safety Air Fuse upstream of hose and use an anti-whip device across any
hose coupling without internal shut-off, to prevent hose whipping if a hose fails or coupling
disconnects. See drawing 16585846 and table on page 2. Maintenance frequency is shown in a
circular arrow and defined as h=hours, d=days, and m=months of actual use. Items identified as:

Clutch Adjustment
Models 5RLK2C3, 5RLK2C5, 5RLL2C5, 5RLN2C3 AND 5RLN2C6 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 40 to 120
in-lb (4.5 to 13.5 Nm) torque.
The Light Clutch Spring (color-coded black) is for applications ranging from approximately 15
to 80 in-lb (1.7 to 9 Nm) torque.
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. Rotate the output end of the Angle Head 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.
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.
