WIDE RANGE OF FASTENERS
RPM
SCREWS SCREWS SCREWS SCREWS SCREWS SCREWS
0-1200
1. Install proper fastener driving accessory and set screwdriver for
correct rotation.
2. Adjust clutch setting. See Fig. 4.
3. Place fastener in accessory, contact workpiece and apply
pressure to seat fastener keeping clutches engaged.
4. Upon fastener seating the clutches will ratchet. Disengage
screwdriver from fastener.
NOTE: With Versa-Clutch the operator has the ability to "override”
clutch ratchet if a fastener hits a wood knot, variable hardness in
steel workpieces 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 option to
drive a range of fastener sizes.
