the fastener which can be driven. To lock the clutch for drilling opera-
tions, move to the drill bit position.

shown in FIG. 6. To select the high speed, low torque setting, turn the
tool off and permit to stop. Slide the gear shifter back (away from

NOTE Do not change gears when the tool is running. If you are hav-
ing trouble changing gears, make sure that the dual range gear shifter
is either completely pushed forward or completely pushed back.

tighten securely by holding the rear half of the chuck and rotating
the front portion in the clockwise direction.
To release the accessory, repeat steps 1 and 2 listed above.
