or incorrect pilot holes. Increased operator pressure will usually cause the
clutches to pick-up and continue to seat the fastener. Further, a quick twist of
the collar will change the clutch setting to overcome most driving difficulties
and will provide for immediate change in torque output giving the operator
the option to drive a range of fastener sizes.
Changing Clutches
1. Remove clutch housing by unscrewing (left hand thread).
2. Clamp tool or clutch housing in a resilient clamp.
3. Remove round clutch retaining rings with a very small screwdriver
(See Figure 8).
4. Install new clutches and new retaining rings.
NOTE: If the output spindle slides toward inside of gear case, remove dead
spindle spring and thread a 5/16"-18 bolt or cap screw into end of spindle and
