Clutch Adjustment
No. 5C1 and 5C3 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 application since it will give precise adjustment from medium-light to the maximum torque
of the Tool.
The Light Clutch Spring (color-coded black for identification) is for applications ranging from
very light to medium-light 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. 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 compresion 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. In any event it is recommended that final adjustment be made by gradual
progression. Observe also that the clutch, when equipped with the Heavy Spring, can be
set beyond the torque capacity of the high speed, low-torque Tools, in which case the Tool
will stall before the clutch ratchets.
Parts and Maintenance
When the life of the tool has expired, it is recommended that the tool be disassembled,
degreased and parts be separated by material so that they can be recycled.
