7. This tool will not stop moving immediately. Do not lay the tool down
or leave it unattended until it has come to a complete stop. A part that
is moving could make the tool jump or grab a surface and pull the
tool out of your control.
8. Use an appropriate dust res pi rat or when working for an extended
period of time. This will help prevent breathing in the fine dust
created while working.
WARNING! Dust that is created by power sanding, sawing, grinding,
drilling, and other construction activities may contain chemicals that
are known to cause cancer, birth defects, or other genetic
abnormalities. The level of risk from exposure to these chemicals
varies, according to how often this type of work is performed. In order
to reduce exposure to these chemicals, work in a well-ventilated area,
and use approved safety equipment, such as a dust mask that is
specifically designed to filter out microscopic particles.
9. Always make sure the work surface is free from nails and other
foreign objects. Cutting into a nail can cause the bit and tool to jump
and damage the bit.
10. After changing the bits and accessories or making adjustments , make
sure the chuck and any other adjustment devices are securely
tightened. Loose adjustment devices will be violently thrown.
11. Always use the correct chuck size. If the chuck size is larger than the
accessory shank size it will not grip the shank properly, leading to
possible injury to the operator , damage to the tool or work piece.
12. Always check accessory bits, etc. for damage before each use.
Damaged accessories can break during use and cause serious injury.
13. Never use dull or damaged bits. Sharp bits must be handled with
care. Damaged bits can snap during use. Dull bits require more force
to push the tool, possibly causing the bit to break.
14. Never touch the bit during or immediately after use. After use, the bit
will be too hot to be touched by bare hands.

V4.0 3/8 in. dr Angle Air Drill 8571762
15. If devices are used for the connection of dust extraction and
collection facilities, ensure these are connected and properly used.
Use of a dust collection system reduces dust-related hazards.
AIR TOOL PRECAUTIONS
1. Extended exposure to air tool noise may cause hearing loss. Ear
protection gear can reduce or eliminate the noise level.
2. Inspect the tool's air line for cracks, fraying or other faults before
each use. Discontinue use if the air line is damaged or hissing is
heard from the air line or connectors, while operating the tool.
Replace the defective component/air line.
3. Do not allow people, mobile equipment or vehicles to pass over the
unprotected air line. Position the air line away from high traffic areas,
in a reinforced conduit or place planks on both sides of the airline to
create a protective trench.
4. Prevent damage to the air line by observing the following:
a. Never carry the tool by the air line.
b. Keep the air line behind the tool and out of the tool's work path.
c. Keep the air line away from heat, oil, sharp edges or
moving parts.
d. Do not wrap the air line around the tool as sharp edges may
pierce or crack the airline. Coil the air line when storing.
5. A damaged or disconnected air line under pressure may whip around
and inflict personal injury or damage the work area. Secure the
compressor's air line to a fixed or permanent structure with clamps
or cable ties.
6. Install an in-line shutoff valve or regulator to allow immediate control
over the air supply in an emergency, even if a hose is ruptured.

VIBRATION PRECAUTIONS
This tool vibrates during use. Repeated or long-term exposure to
vibration may cause temporary or permanent physical injury, particularly
to the hands, arms and shoulders.
1. Anyone using vibrating tools regularly or for an extended period
should first be examined by a doctor and then have regular medical
check-ups to ensure medical problems are not being caused by or
worsened from tool use. Pregnant women or people who have
impaired blood circulation to the hands, past hand injuries, nervous
system disorders, diabetes, or Raynaud's Disease should not use this
tool. If you feel any medical symptoms related to vibrations (such as
tingling, numbness, and white or blue fingers), seek medical attention
as soon as possible.
2. Do not smoke during use. Nicotine reduces the blood flow to the
hands and fingers, increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the vibration effects on the user.
4. Use tools with the lowest amount of vibration when there is a choice
between different processes.
5. Do not use for extended periods. Take frequent breaks when using
this tool.
6. Let the tool do the work. Grip the tool as lightly as possible (while
still keeping safe control of it).
WARNING! If abnormal vibrations occur, stop using this
tool immediately.
USE AND CARE OF THE TOOL
1. Use the correct tool for the job. This tool was designed for a specific
function. Do not modify or alter this tool or use it for an
unintended purpose.

3. Avoid unintentional starts. Be sure that the regulator/throttle switch is
in the neutral or OFF position when not in use and before connecting
it to any air source.
4. Remove adjusting keys and wrenches from the tool before operation
or connecting it to a power source. A wrench or key that is left
attached to a rotating part of the tool increases the risk of
personal injury.
INSTALLING AIR QUICK COUPLER
Prepare a standard 1/4 in. NPT male air quick coupler for use with
your tool.
1. Wrap the external threads of the male quick coupler with sealant tape.
a. Wrap the tape in a clockwise direction so it will not unravel.
b. Do not tape all the threads. Leave several leading threads
unwrapped for easier alignment.
2. Screw the quick coupler into the tool's air inlet and tighten with a
wrench until snug.
3. Run the compressor at a low volume and check the connection for air
leaks. Do not use the tool until all air leaks are repaired or the faulty
component is replaced.

1. Connect the drill to the air supply.
PUSH ROTATE
CLOCKWISE
2. Hold the tool firmly and place the drill bit tip to the point to be drilled.
3. Depress the throttle to start the drill. Move the drill bit into the
workpiece applying only enough pressure to keep the bit cutting.
CAUTION! Do not force or apply side pressure to elongate the hole.
4. If the material to be drilled is free standing it should be secured in a
vice or with clamps to keep it from turning as the drill bit rotates.
NOTE: When drilling metals, use alight oil on the drill bit to keep from
overheating. Oil will prolong the drill bit life and improve the
drilling action.
Visit www.princessauto.com for more information 11

8571762 3/8 in. dr Angle Air Drill V4.0
NOTE: For hard smooth surfaces, use a centre punch to mark the
desired hole location. This will prevent the drill bit from slipping as
drilling commences.
5. A pilot hole may be necessary to assist the final drill size through the
workpiece. Insert a smaller drill bit into the chuck. Follow steps 1
through 3 above and drill a pilot hole in the middle of the centre
punch mark where the final hole is to be drilled. Insert the final sized
drill bit in the chuck. Hold the drill firmly and place the bit at the
entrance of the pilot hole and depress the trigger.
WARNING! Be prepared for drill bit binding on breakthrough. When
these situations occur, the drill has a tendency to grab and kick in the
opposite direction which could cause loss of control. If you are not
prepared, this loss of control can result in damage and/or
personal injury.
6. If the drill bit jams in the workpiece or if the drill stalls, release the
throttle immediately. Remove the drill bit from the workpiece and
determine the reason for jamming.
MAINTENANCE
1. Make sure the throttle lever is in the OFF position and the air source
is removed from the tool before performing any inspection,
maintenance, or cleaning.
2. Before each use: Check the general condition of the tool. Check for
misalignment or binding of moving parts, cracked or broken parts,
damaged hoses, and any other conditions that may affect the safe
operation of the tool. If abnormal noise or vibration occurs, have the
problem corrected before further use. Do not use
damaged equipment.
12 For technical questions call1·800-665-8685

V4.0 3/8 in. dr Angle Air Drill 8571762
3. Daily maintenance: Use a soft, dry cloth to remove all dirt, grease,
and debris from the exterior of the tool. Do not use solvents to clean
the tool.
4. When servicing, use only identical replacement parts. Use
accessories that are only intended for use with this tool. Replace
damaged parts immediately.
5. If repairs are required, bring your tool to an authorized service center.
WARNING! Only qualified service personnel should repair the tool. An
improperly repaired tool may present a hazard to the user
and/or others.
LUBRICATION
Only use air tool oil to lubricate the tool. Other lubricants may not be
suitable and could damage the tool or cause a malfunction during use.
1. It is very important that the tool be properly lubricated. Without
proper lubrication, the tool will not work properly and parts will wear
prematurely. Manually dropping a drop or two of air tool oil once a
day into the tool's oil inlet is better than using an automatic in-line
lubricator, which should only be required when there are multiple
users of the same tool.
2. Keep the air line lubricator filled and correctly adjusted. The in-line
lubricator should be regularly checked and filled with air tool oil.
Proper adjustment of the in-line lubricator is performed by placing a
sheet of paper next to the exhaust ports and holding the throttle open
approximately 30 seconds. The lubricator is properly set when a light
stain of oil collects on the paper. Excessive amounts of oil should
be avoided.
Visit www.princessauto.com for more information 13

8571762 3/8 in. dr Angle Air Drill V4.0
3. Air tool oil is the only recommended lubricant for use in all air tools.
Do not try to use other types of lubricants to oil your tools. Using the
wrong lubricant will cause premature tool failure and I or loss of
power. Use only recommended lubricants, specially made for
pneumatic applications. Substitutes may harm the rubber
compounds in the tool's 0-rings and other rubber parts.
4. Oiling your air tool regularly is important, but also is important not to
OVER oil your air tool. Over oiling can cause premature tool failure.
Your tool may not be ruined, but it will begin to experience loss of
power that will continually get worse until it no longer works. The
tool then has to be taken apart and cleaned of excess oil.
5. All air tools are packed in grease to prevent corrosion of internal
parts during shipping and storage. We recommend that you clean
this out to have optimum performance from your new air tool. Use
two drops of air tool oil to lubricate the tool and run the tool under no
load until exhaust is clear.
6. In the event that it becomes necessary to store the tool for an
extended period of time (overnight, weekend, etc.), it should receive a
generous amount of lubrication at that time. The tool should be run
for approximately 30 seconds to ensure oil has been evenly
distributed throughout the tool. The tool should be stored in a clean
and dry environment.
CAUTION! Do not at any time allow brake fluids, gasoline, petroleum-
based products, penetrating oils, etc. to come in contact with plastic
parts. They contain chemicals that can damage, weaken or
destroy plastic.
STORAGE
When not in use for an extended period, apply a thin coat of lubricant to
the steel parts to avoid rust. Remove the lubricant before using the tool
again. Keep this tool and its accessories in a clean, dry location and out
of the reach of children.
