11. Remove adjusting keys and
wrenches. Check that keys and
adjusting wrenches are removed
from the tool or machine work surface
before plugging it in.
proximity to heart pacemaker could
cause pacemaker interference or
pacemaker failure. In addition, people
with pacemakers should:
• Avoid operating alone.
• Don’t use with power switch locked
on.
• Properly maintain and inspect to
avoid electrical shock.
12. Avoid unintentional starting. Do not
carry any tool with your finger on the
trigger, whether it is plugged in or not.
• Any power cord must be properly
grounded. Ground Fault Circuit
Interrupter (GFCI) should also be
implemented – it prevents sustained
electrical shock.
13. Stay alert. Watch what you are doing,
use common sense. Do not operate
any tool when you are tired.
14. Take caution as some woods
contain preservatives such as
copper chromium arsenate (CCA)
which can be toxic. When drilling
these materials extra care should be
taken to avoid inhalation and minimize
skin contact.
17. Check for damaged parts. Before
using any tool, any part that appears
damaged should be carefully checked
to determine that it will operate
properly and perform its intended
function. Check for alignment and
binding of moving parts; any broken
parts or mounting fixtures; and any
other condition that may affect proper
operation. Any part that is damaged
should be properly repaired or replaced
by a qualified technician. Do not use
the tool if the trigger does not turn On
and Off properly.
15. WARNING: Some dust created by
power sanding, sawing, grinding,
drilling, and other construction
activities, contains chemicals
known [to the State of California] to
cause cancer, birth defects or other
reproductive harm. Some examples
of these chemicals are:
Lead from lead-based paints
18. Guard against electric shock.
Prevent body contact with grounded
surfaces such as pipes, radiators,
ranges, and refrigerator enclosures.
Crystalline silica from bricks and
cement or other masonry products
Arsenic and chromium from chemically
treated lumber
Your risk from these exposures
varies, depending on how often you
do this type of work. To reduce your
exposure to these chemicals: work in
a well ventilated area, and work with
approved safety equipment, such as
those dust masks that are specially
designed to filter out microscopic
particles. (California Health & Safety
Code § 25249.5, et seq.)
19. Replacement parts and accessories.
When servicing, use only identical
replacement parts. Use of any other
parts will void the warranty. Only use
accessories intended for use with
this tool. Approved accessories are
available from Harbor Freight Tools.
20. Do not operate tool if under the
influence of alcohol or drugs. Read
warning labels on prescriptions to
16. People with pacemakers should
consult their physician(s) before
use. Electromagnetic fields in close
determine if your judgment or reflexes
are impaired while taking drugs. If there
is any doubt, do not operate the tool.

21. Use proper size and type extension
cord. If an extension cord is required,
it must be of the proper size and type
to supply the correct current to the
tool without heating up. Otherwise,
the extension cord could melt and
catch fire, or cause electrical damage
to the tool. This tool requires use of
an extension cord of 0 to 10 amps
capability (up to 50 feet), with wire size
rated at 18 AWG. Longer extension
cords require larger size wire. If you
are using the tool outdoors, use an
extension cord rated for outdoor use
(signified by “WA” on the jacket).

use lubricants with brass, copper, and
cast iron. Grasp the handles firmly with
both hands and slowly squeeze the
Trigger (34). Never operate the tool
without the side handle. Never force
the tool. Only apply light pressure
when horizontal drilling.
Note: Always use sharp bits. Dull or
damaged bits may cause undue stress
on the drill and possibly break causing
injury. Bits are available at Harbor
Freight Tools.
8. When driving screws, use bits suitable
for the type and size of screw you are
using. Drill a pilot hole for the screw
head to bite into. Use the lowest
torque setting. Grasp the handles
firmly with both hands and slowly
squeeze the Trigger (34). Never force
the tool. To back out a screw, stop and
change the Directional Switch to the
back position.
4. Securely clamp your workpiece.
5. Locate the Side Handle on the desired
side of the tool.
Drilling
6. When drilling wood, place the bit
at the point to be drilled. If you are
drilling a hard, smooth surface, use a
punch to mark the drill location. Set
the Directional Switch forward. Grasp
the handles firmly with both hands
and slowly squeeze the Trigger (34).
Never operate the tool without the side
handle. Never force the tool. Only
apply light pressure when horizontal
drilling. If you need more or less
torque, use the torque adjustment on
the top of the drill.
MAINTENANCE
1. Unplug the drill while performing
maintenance.
2. Periodically check the mounting screws
and tighten if necessary.
3. Clean the unit with a damp cloth.
Never use solvents to clean the unit.
4. Inspect the chuck and remove any dirt
or debris.
Note: When drilling plastics or plastic
coated chip board, follow the same
directions as stated in number 5 for
wood.
5. Inspect the Carbon Brushes (29). See
Figure 1 on page 4.
• Remove the Carbon Brush Cap
(30) on top of the drill.
Note: If a bit becomes wedged into the
workpiece, stop and change the
Directional Switch to the reverse
position. Then slowly squeeze the
Trigger to back the bit out of the work
piece.
• Take the Carbon Brush (29) out of
the Brush Holder (28). If it is dirty,
use a pencil eraser to clean it. If it
is worn, replace it and replace the
Carbon Brush Cap (30). If you
replace one Carbon Brush, you
must replace them both. Repeat
the process with the Carbon Brush
Cap (30) on the bottom of the drill.
7. When drilling metal, always use a
punch to mark the drilling position.
Use a lubricant to prolong the life of
the bit and increase the drilling action
with most metals. With steel, tin, and
sheet metal use a light machine oil,
with aluminum, use paraffin. Do not
