1. Do not operate any tool when tired or under the influence of drugs,
alcohol or medications.
2. Avoid wearing clothes or jewelry that can become entangled with the
moving parts of a tool. Keep long hair covered or bound.
3. Do not overreach when operating the tool. Proper footing and
balance enables better control in unexpected situations.
4. Support the workpiece or clamp it to a stable platform. Holding the
workpiece by hand or against your body may lead to personal injury.
SPECIFIC SAFETY PRECAUTIONS
1. Only use accessories that are specifically designed for use with the
tool. Make sure accessories are capable of handling the tool's
maximum speed of 2,500 RPM. Ensure the accessory is
tightly installed.
2. Keep hands and fingers away from grinding area. Any part of body
coming in contact with moving parts could cause injury.
3. When operating the tool, use proper eye, breathing and hearing
protection as well as protective gloves.
WARNING! Flying debris can cause permanent eye damage.
Prescription eyeglasses are not a replacement for proper
eye protection.
4. Use protective gloves that will reduce vibration and protect your
hands in case of unexpected situations.
5. To maintain complete control, firmly hold your tool with both hands.
Do not place hands over air vents. Proper cooling of the motor is
necessary to ensure normal life of the tool.
6. Never point the cutter towards yourself. If it should slip, part of your
body could come in contact with moving parts.

7. Never force the tool. Excessive pressure could bend or break the
mandrel, resulting in damage to the tool, your work piece or serious
personal injury. If your tool runs smoothly under no load , but does
not run smoothly under load , then excessive pressure is being used.
8. 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.
9. Hold the tool by the insulated gripping surfaces when performing an
operation where the cutting tool may contact hidden wiring or its own
cord. Contact with a"live" wire will make exposed metal parts of the
tool "live" and shock the operator.
1 0. Use an appropriate dust respi rata r 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 awell-ventilated area,
and use approved safety equipment, such as a dust mask that is
specifically designed to filter out microscopic particles.
11. 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.
12. After changing the bits and accessories or making adjustments, make
sure the collet nut and any other adjustment devices are securely
tightened. Loose adjustment devices will be violently thrown.
13. Remove any adjusting keys or wrenches before turning the tool on.

V4.0 2 in. dr Straight Air Die Grinder 8569634
14. Always use the correct collet size. If the collet 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.
15. Always check accessory bits, grinding stones, cut-off wheels etc. for
damage before each use. Damaged accessories can break during use
and cause serious injury.
16. 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.
17. Never touch the bit during or immediately after use. After use, the bit
will be too hot to be touched by bare hands.
18. 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.
Visit www.princessauto.com for more information 7

8569634 2 in. dr Straight Air Die Grinder V4.0
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.
KICKBACK PRECAUTIONS
Kickback is a sudden reaction to a pinched, bound or misaligned blade,
causing an uncontrolled tool to lift up and out of the workpiece toward
the operator;- when the blade is pinched or bound tightly by the cut
workpiece closing down, the blade stalls and the motor reaction drives
the unit rapidly back toward the operator. Kickback may result in loss of
control of the tool leading to serious personal injury and I or damage to
the workpiece and I or tool.
Kickback can be avoided by taking proper precautions:
1. Maintain a firm grip on the tool and position your body and arms to
allow you to resist kickback forces. Kickback will propel the tool in
the direction opposite to the wheel's movement at the time
of snagging.
2. Never place your hand near the blade. If kickback occurs, the wheel
may pass over your hand and seriously injury you. Use clamps or a
vice to hold down the workpiece.
8
For technical questions call1·800-665-8685

V4.0 2 in. dr Straight Air Die Grinder 8569634
3. Use special care when working on corners, sharp edges etc. Corners,
sharp edges or bouncing have a tendency to snag the blade and
cause loss of control or kickback.
4. When the blade is binding, or when interrupting a cut for any reason,
release the trigger and hold the saw motionless in the material until
the blade comes to a complete stop. Never attempt to remove the
saw from the workpiece or pull the saw backward while the blade is
in motion or kickback may occur. Investigate and take corrective
actions to eliminate the cause of blade binding.
5. When restarting a blade in the workpiece, center the blade in the cut
and check that blade teeth are not engaged into the material. If saw
blade is binding, it may walk up or kickback from the workpiece as
the cut-off saw is restarted.
6. Support large panels to minimize the risk of blade pinching and
kickback. Large panels tend to sag under their own weight. Supports
must be placed under the panel on both sides , near the line of cut
and near the edge of the panel.
To minimize the risk of blade pinching and kickback, when cutting
operation requires the resting of the tool on the workpiece, the tool
should be rested on the larger portion and the smaller piece cut off.
7. Use extra caution when making a "plunge cut" into existing walls or
other blind areas. The protruding blade may cut objects that can
cause kickback.
8. Only use blades designed for the tool. Do not use dull or damaged
blades. Unsharpened or improperly set blades produce narrow cuts
causing excessive friction, blade binding and kickback. Keep blades
sharp and clean. Gum and wood pitch hardened on blades slows the
saw and increases potential for kickback.
9. Never force the saw. Forcing the tool can cause uneven cuts, loss of
accuracy , and possible kickback. Push the tool forward at a speed so
that the blade cuts without slowing.

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.

10 For technical questions call1·800-665-8685

V4.0 2 in. dr Straight Air Die Grinder 8569634
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.

OPERATION
WARNING! Hand, wrist and arm injury may result from repetitive work
motion and overexposure to vibration.
WARNING! Disconnect the tool from its air supply before changing
accessories, servicing or performing maintenance.
1. Select the appropriate accessory for the task. Only use accessories
which are specifically designed for use with the die grinder. Make
sure they are capable of handling the tool's maximum speed of 2,500
RPM. Make sure the accessory is tightly installed.
2. Attach the accessory to the grinder.
a. Push the spanner in the collet nut.
b. Inserting mandrel a minimum of 1/4 in. into collet minimizes
vibration, delivers better results, and reduces the risk of injury.
CAUTION! Inserting, into collet a minimum of 1/4 in. to prevent wheel
or file from disengaging with grinder while in use.
c. Tighten collet securely with wrench provided.
WARNING! Always check cutter for tightness before each use. A loose
cutter can be thrown from tool with considerable force, causing injury.
3. Connect the tool to the air hose.
4. Place the bit over the work piece and turn on the grinder.
5. Use grinding wheels when working with hard materials and rotary
files for milling soft materials such as nonferrous metals (aluminum,
brass, copper, etc.) Using grinding wheels when working with soft
materials will clog the wheel, preventing it from cutting as it
was designed.
WARNING! Do not allow the tool to run with no load for an extended
period of time as this will shorten its life.

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.
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 male connector is better than using an automatic
in-line lubricator, which should only be required when there are
multiple users of the same tool.
Visit www.princessauto.com for more information 13

8569634 2 in. dr Straight Air Die Grinder V4.0
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.
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.
