Selector
ELECTRIC BRAKE
When the trigger switch is released, it
activates the brake to stop the chuck
quickly. This is especially useful in the
repetitive driving and removal of screws.
DIRECTION-OF-ROTATION
SELECTOR (FIG. 7)
The direction of bit rotation is reversible and
is controlled by a selector located above
the trigger switch. With the
the normal operating position:
1. Position the direction-of-rotation
selector to the left of the tool for forward
rotation.
2. Position the direction-of-rotation
selector to the right of the tool for
reverse rotation.
3. Setting the direction-of-rotation selector
in the OFF (center-lock) position helps
reduce the possibility of accidental
starting when not in use.
NOTICE: To prevent gear damage,
always allow the hammer drill to come
to a complete stop before changing the
direction of rotation.
