the neutral or OFF position when not in use and before connecting it to
any air source.
7. Serious injury or death may occur from inhaling compressed air. The air
stream may contain carbon monoxide, toxic vapors or solid particles.
Never inhale compressed air directly from the pump or air tool.
SPECIFIC SAFETY PRECAUTIONS
WARNING! DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to the tool safety rules. If you use this
tool unsafely or incorrectly, you can suffer serious personal injury.
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.
2. Do not use the tool if any parts are damage broken or misplaced. Repair or
replace the parts.
3. 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.

V1.0 3/8 in. Angled Reversible Air Drill 8843559

4. Always make sure the work surface is free from nails and other foreign
objects.
5. 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.
6. Always check accessory bits for damage before each use. Damaged
accessories can break during use and cause serious injury.
7. 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.
8. 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.
9. 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 tool’s movement at the time of snagging.
10. Use metal and voltage detectors to locate hidden electric, water or gas
lines. Avoid touching live components or conductors.
11. Before drilling, check that there is sufficient clearance for the drill bit
under the workpiece.
12. If you are interrupted when operating the drill, complete the process and
switch off the tool before looking up.
AIR TOOL PRECAUTIONS
1. Use only clean and dry compressed air as a power source. Contaminated
or moist air will gradually damage the tool.
2. 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.
3. Discontinue tool use if it does not work properly or air is leaking. Tag or
mark the tool as ‘defective’ or ‘out of service’ until repaired.
4. Check the manufacturer’s maximum pressure rating for air tools and
accessories. Compressor outlet pressure must be regulated to never
exceed the maximum pressure rating of the tool (see Specifications).
Exceeding the maximum PSI rating can create a bursting hazard, causing
injury and property damage.
5. Attach all accessories properly to the tool before connecting the air
supply. A loose accessory may detach or break during operation.

8843559 3/8 in. Angled Reversible Air Drill V1.0
6 For technical questions call 1-800-665-8685
6. Never use oxygen, combustible gas or any other bottled gas as a power
source. Any power source other than an air compressor could cause an
explosion and serious personal injury.
7. Turn OFF the valve and discharge any remaining air pressure after each
use or before adjusting the tool.
8. Do not leave the air tool unattended with its compressed air supply on.
Turn off the compressed air supply and bleed the air tool of any remaining
compressed air before leaving the air tool unattended.
9. Serious injury may occur from loose debris being propelled at high speeds
from the compressed air stream. Always wear OSHA approved safety
glasses to protect the eyes during operation of the air compressor.
10. Never point the air stream or tools at any point of your body, other people
or animals. Debris and dust may be ejected without warning. Always turn
off the air compressor and drain tank pressure completely before
attempting maintenance or attaching air tools. Release pressure slowly
from the system.
AIR HOSE PRECAUTIONS
1. Inspect the tool's air hose for cracks, fraying or other faults before each
use. Discontinue use if the air hose is damaged or hissing is heard from
the air hose or couplers. Replace the defective air hose.
2. Do not allow people, mobile equipment or vehicles to pass over the
unprotected air hose. Position the air hose away from high traffic areas,
in a reinforced conduit or place planks on both sides of the air hose to
create a protective trench.
3. Prevent damage to the air hose by observing the following:
a. Never carry the tool by the air hose.
b. Keep the air hose behind the tool and out of the tool's work path.
c. Keep the air hose away from heat, oil, sharp edges or moving parts.
d. Do not wrap the air hose around the tool as sharp edges may pierce
or crack the air hose. Gently coil the hose and either hang on a hook
or fasten with a device to keep hose together when storing.
4. A damaged or disconnected air hose under pressure may whip around and
inflict personal injury or damage the work area. Secure the compressor's
air hose to a fixed or permanent structure with clamps or cable ties.

COMPRESSOR/TANK PRECAUTIONS
DANGER! Do not use an air tank beyond its expiration date. A tank rupture or
explosion may kill or cause a serious injury to yourself or a bystander. Disable
and discard the air tank according to the your municipality by-laws.
1. Never drill into, weld, patch or modify the air tank. Immediately replace the
tank or compressor if an air leak develops. The leak may lead to a rupture.
2. Never make adjustments to the components that control tank pressure.
Serious injury or death may occur if modifications are made to the pressure
switch, safety relief valve or other components that control the tank pressure.
3. Check operation of the pressure relief valve on a regular basis and never
operate without a factory approved pressure relief valve. Do not make
alterations to the factory operating pressure settings.
POWER TOOL PRECAUTIONS
Tool accessory is a general term that refers to drill bit, saw or cutting blades,
grinding wheel, etc. as appropriate for the tool.
1. Do not use any power tool with a malfunctioning power switch or control.
A power tool that fails to respond to the controls is dangerous and can
cause an injury. A qualified technician must repair and verify the power
tool is operating correctly, before it can be used.
2. Do not cover the air vents.
3. Disconnect the power source before installing or servicing the tool.
4. Never force the tool. Excessive pressure could break the tool, resulting in
damage to your workpiece or serious personal injury. Excessive pressure is
the cause if your tool runs smoothly under no load, but roughly under load.
5. Keep hands and fingers away from the work area. Any part of body
contacting the tool’s working parts could cause an injury.
6. Only use accessories that are specifically designed for use with the tool.
Ensure the accessory is tightly installed.
7. Only use an accessory that exceeds the No Load Speed rating (see
Specifications).
8. Before using the tool on a workpiece, test the tool by running it at the
highest no load speed for at least 30 seconds in a safe position. Stop
immediately if there is any abnormal vibration or wobbling. Check the tool
to determine the cause.
9. Never touch the tool accessory or workpiece during or immediately after use.
They may be hot and could inflict a burn injury.

8843559 3/8 in. Angled Reversible Air Drill V1.0
8 For technical questions call 1-800-665-8685
10. Never use a tool with a cracked or worn tool accessory. Change the tool
accessory before using it.
DRILLING PRECAUTIONS
CAUTION! Immediately release the trigger if the drill bit becomes stuck or
jammed. The tool’s torque can twist your arm and cause an injury. The tool may
twist out of your grip and cause an injury to yourself or a bystander.
The term bit refers to any drill bits, router bits or tool accessories that
penetrate a material and creates a cavity through a rotary motion.
1. Verify the drill’s rotation before starting the drill.
2. A loose or mismatched bit may be ejected by the tool, causing an injury to
the user or a bystander. It may also fail to penetrate the material as the
point may move around under pressure, damaging the workpiece.
a. Ensure the bit shank size matches the tool’s chuck.
b. Tighten the chuck so the shank is tightly held with no room to move.
3. Always hold the tool firmly in your hands before switching the tool ON.
The reaction to the motor’s torque may cause the tool to twist, as it
accelerates to full speed.
4. Do not use drill as a router or try to elongate or enlarge holes by twisting
the drill. Drill bits can break and can cause injury.
5. Do not apply side pressure on the bit unless it is designed for such a
purpose. The bit may bind or break.
6. Never attempt to change the rotation direction while the switch is ON. To
do so, may damage the interlock feature built into the switch. Be sure the
switch is OFF and the motor has completely stopped before changing the
rotation direction.
UNPACKING
WARNING! Do not operate the tool if any part is missing. Replace the missing
part before operating. Failure to do so could result in a malfunction and
personal injury.
Remove the parts and accessories from the packaging and inspect for damage.

INSTALL AIR PLUG
Prepare a standard 1/4 in. NPT male air plug (sold separately) for use with your
tool.
1. Wrap the external threads of the male plug with sealant tape.
a. Wrap 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. Remove the air inlet (G) cap.
3. Screw the plug into the tool's air inlet and tighten with a wrench until snug.
4. 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.
IMPORTANT! Vibration may cause failure if a quick coupler is connected
directly to the air tool. To overcome this, connect a leader hose to the tool. A
quick coupler may then be used to connect the leader hose to the air line hose.
OPERATION
PRESSURE DROP
Apply the air consumption and pressure rate numbers to the tool’s air inlet, not
the compressor’s outlet. Calculate the pressure drop for your air supply set-up
and increase the compressor outlet pressure to compensate. Make sure you do
not exceed the maximum pressure for any part of your air supply system.

8843559 3/8 in. Angled Reversible Air Drill V1.0
10 For technical questions call 1-800-665-8685
Installing a pressure gauge at the tool inlet is the best way to measure the air
pressure and adjust the compressor’s output.
TOOL OPERATION
1. Clean the air drill of packing grease before first use. See the Air Tool
Lubrication section for instructions.
2. Install a drill bit into the chuck jaws (A) and hand-tighten. Make sure the
bit’s shaft is straight. Tighten using the chuck key. Remove the chuck key.
3. Connect the air drill to the end of the air hose.
4. Set the compressor to the correct air pressure and flow (see Specifications).
Start the compressor.
5. The chuck rotates clockwise (forward) when the reverse button (F) is
popped out. Push the button in and rotate it clockwise to lock it into place.
The chuck will now rotate counterclockwise (reverse). Pop it out to restore
clockwise rotation. Disconnect the air hose before switching from one
direction to the other.
6. Test the drill under no load to confirm the bit is installed correctly.
7. Place the drill bit point onto the workpiece surface.
a. Use a center punch to mark the spot to prevent the drill bit from
skittering across the surface.
b. A larger drill bit may require a pilot hole. Use a narrower bit to drill
the pilot hole first, then install the larger bit.
c. Apply a drop of cutting oil to the drill bit and surface before drilling
metal.
8. Squeeze the trigger and lightly push the drill against the workpiece. Allow
the bit to cut the material. Continue to apply gentle pressure until the
proper depth is reached.
9. Hold the trigger until the drill bit is removed from the hole, then release
the trigger.
10. Shut the compressor off once the task is completed. Squeeze the trigger to
release residual compressed air from the hose and tool. Disconnect the tool.
11. Remove the bit and store both the bit and the drill.
CARE & MAINTENANCE
1. Maintain the tool with care. A tool in good condition is efficient, easier to
control and will have fewer problems.

V1.0 3/8 in. Angled Reversible Air Drill 8843559

WARNING! Only qualified service personnel should repair the tool. An
improperly repaired tool may present a hazard to the user and/or others.
AIR TOOL LUBRICATION
NOTICE! Only use air tool oil to lubricate the tool. Other lubricants are not
suitable and will damage the tool or cause a malfunction during use.
NOTICE! Never use a penetrating oil to lubricate an air tool. Penetrating oil acts
as a solvent that will dissolve the tool’s grease packing and may damage the
o-rings, causing the tool to seize or malfunction.
1. All air tools have an internal coating of grease to prevent corrosion during
shipping and storage. Remove this grease by adding a generous amount of
air tool oil in the air inlet and then run the tool under no load until the
exhaust is clear.
2. Manually add a drop or two of air tool oil into the tool’s male plug before
each use and after every hour of continuous use. The tool will not work
properly without lubrication and parts will wear prematurely.
3. Avoid adding too much air tool oil as this can cause premature power loss
and eventual tool failure. A qualified technician will need to take the tool
apart and clean out the excess oil.
4. Apply a generous amount of air tool oil to the tool before storing it for an
extended period of time (overnight, weekend, etc.). Run the tool for
approximately 30 seconds to ensure the oil is evenly distributed
throughout the tool. Store it in a clean and dry location.
GREASE THE HEAD ASSEMBLY
Greasing the head assembly is recommended to extend the tool’s life. Press the
grease gun nozzle against the grease fitting (C) and force several drops of grease
into the head. Run the tool for several moments to distribute the grease.

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.
DISPOSAL
Recycle a tool damaged beyond repair at the appropriate facility.
Contact your local municipality for a list of disposal facilities or by-laws for
electronic devices, batteries, oil or other toxic liquids.
IMPORTANT! DO NOT pollute the environment by allowing uncontrolled
discharge of waste oil.
