2.Set screwdriver for reverse rotation.

3.Start screwdriver and place bit in screw.

4.Exert forward pressure to remove screw.

MAINTENANCE

KEEP TOOL CLEAN

Periodically blow out all air passages with dry, compressed air. All plastic parts should be cleaned with soft damp cloth. NEVER use solvents, to clean plastic parts. They could possibly dissolve or otherwise damage the material.

CAUTION: Wear safety glasses while performing this operation.

FAILURE TO START

Should your tool fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet. Also, check for blown fuses or open circuit breakers in the line.

CHECK CLUTCH CONDITION

CAUTION: DISCONNECT TOOL FROM POWER SOURCE

Periodically, depending on use, screwdriver clutch jaws should be inspected for wear. This may be done by removing the screwdriver mechanism housing (A), Fig. 5, from the power unit.

NOTES: The clutch housing is attached to the power unit with left- hand threads. The depth stop assembly may be removed from the clutch housing to expose a set of wrenching “flats” (B), Fig. 5, on the clutch housing. These “flats” permit the use of a wrench to aid in clutch housing removal.
