shearing off the head.

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.
