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 16585762 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:
1. Air filter
2. Regulator
3. Lubricator
4. Emergency shut-off valve
5. Hose diameter
6. Thread size

Clutch Adjustment

Models ending in C1 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, three Clutch Springs are offered.
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" hexagon steel (Allen Key) into the clutch hexagon recess in the Bit Holder. Rotate
the clutch mechanism until one of the radial holes in the Clutch Adjusting Nut is visible
through the adjusting hole. Insert the end of the No. 5C1-416 Adjusting Key (a hardened
steel pin or rod 3/32" [2 mm] diameter is also suitable) into the hole in the Adjusting Nut to
sprag the Nut against rotation.
3. Grasp the Tool firmly in one hand and rotate the Bit Holder to shift the Nut along the Bit
Holder. This is a left-hand thread; rotating the Bit Holder clockwise when facing the front
increases the compression on the Clutch Spring and raises the torque at which the clutch will
ratchet.
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. In any event it is recommended that final adjustment be made by gradual
progression.
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.
