General Operating Instructions
1. Make sure that the Trigger is in the
off-position, then plug in the tool.
2. Use the Forward/Reverse Switch above the Trigger to
determine the rotation direction of the Chuck. Slide
it to the right side for clockwise Chuck rotation. Slide
to the left side for counterclockwise Chuck rotation.
3. cAUTION! Do not change direction while the drill
is operating. Allow chuck to come to complete
stop prior to changing its direction of rotation.
4. Squeeze the Trigger to start the tool. The Trigger
has a variable speed feature. Pressing it lightly
will make the tool operate slowly; pressing
more will cause the tool to operate faster.
5. To prevent accidents, turn off the tool and
disconnect from power source after use. Clean,
then store the tool indoors out of children’s reach.
Drilling Tips
1. Use only well-sharpened bits that are in
good condition and appropriate to task.
2. Use firm pressure when drilling, but do not press
too hard. Too much pressure will not help the
process and will cause bit to overheat, may
cause bit to bend or break, cause undue strain
on the tool, and may damage the bit or work
piece. Pressing too hard may stall the motor.
3. WARNING! If motor stalls, release Trigger
immediately to prevent damage to the tool.
4. Always drill in a straight line. Bending or twisting
bit while drilling may cause the bit to bend or
break and may damage the work piece.
5. Back off your pressure when you are
about to penetrate the work piece.
6. Keep the motor running when pulling the bit out of
a completed hole to prevent the bit from jamming.
Metal Drilling
1. Use high speed steel, carbide or
specialty bits for metal drilling.
2. Secure the work piece to keep it from
moving during the drilling operation.
3. Use a punch to create a dimple for the bit to start.
4. Start by drilling slowly to keep bit from
moving away from your starting point.
5. As the hole is established, increase tool speed.
Do not go so fast or use so much pressure that
the bit heats up. This can damage the bit and
create an irregular hole. For hard metal or thick
pieces, use cutting oil to keep the bit cool.
6. When drilling large holes in metal, start
by drilling a smaller pilot hole, then using
a larger bit for the final size hole.
Wood Drilling
1. Use high carbon bits or bits specially
designed for wood drilling, such as brad
point, spade bits, forstner bits, etc.
2. Secure the work piece to keep it from
moving during the drilling operation.
3. Start by drilling slowly to keep the bit from
moving away from your starting point.
Increase speed as the hole is established.
4. To prevent or reduce “break out” when the bit
penetrates the work piece, clamp a piece of
scrap material to the back of the work piece.
