% dee%/#"1 Over pressurizing the
tool may cause bursting, abnormal
operation, breakage of the tool or
serious injury to persons. Use only clean, dry,
regulated compressed air at the rated pressure
or within the rated pressure range as marked on
the tool. Always verify prior to using the tool that
the air source has been adjusted to the rated air
pressure or within the rated air-pressure range.
2. Never use oxygen, carbon dioxide, combustible
gases or any bottled gas as an air source
for the tool. Such gases are capable of
explosion and serious injury to persons.
!"+(,$"&8%J(*4,'$"&8#
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.
To reduce the risk of vibration-related injury:
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 or worsened from use. Pregnant
women or people who have impaired blood
circulation to the hand, past hand injuries,
nervous system disorders, diabetes, or Raynaud’s
Disease should not use this tool. If you feel
any symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply 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 vibration
when there is a choice.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
7. To reduce vibration, maintain
tool as explained in this manual.
If abnormal vibration occurs, stop immediately.

2. Attach an air hose to the compressor's air outlet.
Connect the air hose to the air inlet of the tool.
Other components, such as a coupler plug
and quick coupler, will make operation
more efficient, but are not required.

Such a coupler contains an air valve that will
allow the air tool to retain pressure and operate
accidentally after the air supply is disconnected.
M&$*-%Air flow, and therefore tool performance,
can be hindered by undersized air supply components.
The air hose must be long enough to reach
the work area with enough extra length to
allow free movement while working.
3. Turn the tool's throttle or switch to the off position;
refer to Operation section for description of controls.
4. Close the in-line shutoff valve between
the compressor and the tool.
5. Turn on the air compressor according to
the manufacturer's directions and allow it
to build up pressure until it cycles off.
6. Adjust the air compressor's output regulator
so that the air output is enough to properly
power the tool, but the output will not exceed
the tool's maximum air pressure at any time.
Adjust the pressure gradually, while checking the
air output gauge to set the right pressure range.
7. Inspect the air connections for leaks.
Repair any leaks found.
8. If the tool will not be used at this time, turn off
and detach the air supply, safely discharge
any residual air pressure, and release
the throttle and/or turn the switch to its off
position to prevent accidental operation.
9. Residual air pressure should not be present
after the tool is disconnected from the air supply.
However, it is a good safety measure to
attempt to discharge the tool in a safe fashion
after disconnecting to ensure that the tool
is disconnected and not powered.

1. Before using the Fluid Extractor on a vehicle,
park the vehicle on a flat, level surface.
2. Shut down the vehicle and chock its tires.
3. Before beginning fluid extraction, disconnect
the negative battery cable to prevent
accidental starting of the vehicle’s engine.
683"8*%I"7%&(%G(,8#5"##"&8%;7'"9%6Z$(,4$"&8
1. When removing engine oil, run the engine
for at least 5 minutes to warm the oil.
2. Remove the oil dipstick from the engine, or
remove the transmission fluid dipstick or fill plug.
3. Insert the end of the appropriate Extracting Tube
without the adapter into the dipstick opening of the
engine until it reaches the bottom of the oil pan or
into the dipstick fill hole of the transmission until
it reaches the bottom of the transmission pan.
MIG6- Do not bend the Extracting Tube
when inserting. Narrower dipstick tubes may
prevent insertion of the Extracting Tubes.
4. Insert the adapter on the other end of the Extracting
Tube into the Fluid Coupler on top of the Reservoir
Tan k. Insert the adapter fully to avoid leaking.
5. With the Air Control Valve in the closed
position, attach the air supply to the Air Inlet.
6. Turn on the air supply and open the Air
Control Valve. It will take several seconds for
vacuum to build in the Reservoir Tank before
oil or transmission fluid begins to flow.
7. As the fluid starts to flow, continue until all fluid
has been extracted. When finished, close the Air
Control Valve, detach the air supply and remove
the Extracting Tube from the dipstick opening.
8. If the tool requires more force to accomplish
the task, verify that the tool receives sufficient,
unobstructed airflow (CFM) and increase the
pressure (PSI) output of the regulator up to the
maximum air pressure rating of this tool.

9. Disconnect the Extracting Tube from the Fluid
Coupler and remove the Coupler from the Spout.
Pour the collected fluid into an appropriate
container and dispose of in accordance with
all applicable local, state and federal laws.
Do not store fluid in the Reservoir Tank.
10. Clean external surfaces of the tool with a
clean, dry cloth. Clean the Reservoir Tank with
compatible solvent that will not damage it to
remove accumulated debris. Dispose of solvent
properly and allow Reservoir Tank to air dry
completely, then store in a safe, dry, clean location
out of reach of children. Do not allow solvent to
sit in Reservoir Tank for an extended period.
