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 16585788 and table on page 2. Maintenance frequency is shown in
circular arrow and defined as h=hours, d=days, and m=months. Items identified as:
1. Air filter 6. Thread size
2. Regulator 7. Coupling
3. Lubricator 8. Safety Air Fuse
4. Emergency shut-off valve 9. Oil
5. Hose diameter 10. Grease - through fitting
Clutch Adjustment
For Models 7RLL2C6, 7RLL3C6 and 7RLM3C6, 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) 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).
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
Turn off the air supply and disconnect the air supply hose 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 ratchets. 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 use of the tool on the actual
application and increasing or decreasing the delivered torque until the desired setting is
reached. I any event, it is recommended that final adjustment be made by gradual
progression.
