Speed Selector (Fig. 1)
NOTICE: Risk of tool damage. Do not rotate the speed selector lever
while the drill is running or coasting, damage may occur to the tool
Rotate the speed selector lever (B) to the desired speed:
1 = low speed (330 RPM)
2 = high speed (1300 RPM)
NOTE" The first time the tool is run after changing speeds, you may
hear a click on start up. This is normal and does not indicate a problem.
Trigger Switch (Fig. 1)
Depressing the trigger switch (D) turns the tool on, releasing the trigger
switch turns the tool off.
VARIABLE SPEED
A variable speed trigger switch permits speed control--the farther the
trigger is depressed, the higher the speed of the drill.
NOTE" Use lower speeds for starting holes without a center punch,
drilling in metal, plastics or ceramics. Higher speeds are better for
drilling wood and composition boards.
Forward/Reverse Button (Fig. 1)
A forward/reverse button (C) determines the direction of the tool. It is
located in front of the trigger switch.
To select forward rotation, release the trigger switch (D) and depress
the forward/reverse button on the right side of the tool.
To select reverse, depress the forward/reverse button on the left side
of the tool. When changing the position of the button, be sure the
trigger is released.
NOTE" The first time the tool is run after changing the direction of
rotation, you may hear a click on start up. This is normal and does not
indicate a problem.
OPERATION
_WARNING: To reduce the risk of injury, turn unit off
and disconnect ff from power source before installing and
removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
The bit rotates clockwise when the tool is in the forward position and
counterclockwise when the tool is in the reverse position. If the bit
binds, the tool will slow to a manageable level. Using proper hand
position, brace the side handle (I)or tool body against a stud for better
support (Fig. 3).
