SPECIFIC SAFETY INSTRUCTIONS  

AND WARNINGS

CAUTION

:

 This equipment is intended for professional use only 

and only for the applications specified in in this manual.

CAUTION

:

 DO NOT attempt to extract fluids at temperatures 

greater than 175°F (80°C).

CAUTION

:

 This equipment is designed for servicing a variety of 

vehicles; however, differences in makes and models may not allow this 

equipment to be used as intended by the manufacturer. DO NOT attempt 

to force this equipment to fit an application for which it was not designed.

CAUTION

:

 In addition to the guidelines set by this manual, 

always follow the manufacturer provided vehicle maintenance manual 

prior to attempting service of any kind.

WARNING

:

 DO NOT use this equipment with gasoline or other 

flammable liquids or with fluids at temperatures above 175°F (80°C). 

WARNING

:

 Keep away from open flames or excessive heat. 

WARNING

:

 To extract certain fluids, the vehicle may need to 

be lifted. Practice extreme caution when using lifting equipment, and 

ensure that the proper lifting equipment is utilized. 

WARNING

:

 Prior to inserting the extraction hoses into 

any dipstick tube/fluid reservoir, ensure that the extraction hoses 

are clean of any residual fluids. This could cause contamination, 

potentially leading to system failure. 

WARNING

This system creates a vacuum, thus creating 

pressurized fluid. While operating, ensure secure fittings and always 

check the system pressure prior to disconnecting any hose. 

ASSEMBLY

The Main Extraction Reservoir is fully assembled.
1.  Remove the unit and all pieces from the packaging. 

2.  Refer to the parts list to ensure all pieces are present.

3.  Press the Main Suction Hose into the receiving hole on the 

Reservoir Cap. Press in until snug against the cap. The O-Ring will 

hold the Main Suction Hose in place during operation.

4.  Ensure that the Reservoir Lid is properly secured to the Reservoir. 

PREPARING FOR OPERATION

1.  Park the vehicle on a level surface, free from obstruction. Put the 

vehicle in park or neutral; apply the parking brake. 

2.  If extracting oil, start the engine and allow the engine to idle until it 

has reached normal operating temperature. Turn the engine off.

NOTE

If extracting coolant, DO NOT follow Step 2. Allow the engine 

to cool completely before proceeding.

EXTRACTING OIL THROUGH THE DIPSTICK TUBE

1.  Insert the Dipstick Tube Adapter into the vehicle’s dipstick tube until 

it reaches the bottom of the oil pan. 

NOTE

DO NOT bend the Dipstick Tube Adapter while inserting the 

adapter into the dipstick tube. 
2.  Connect the Main Suction Hose to the inserted Dipstick Tube Adapter. 

NOTE

Ensure that the hose connections are tight to prevent leakage 

during the extraction process. 
3.  Press the Main Suction Hose into the Reservoir Cap as described in 

the assembly instructions.

NOTE

Ensure that the Vacuum Release Plug is fully inserted in the 

lower receiving hole prior to operation. If the Vacuum Release Plug is 

not inserted, a vacuum will not be created.  
4.  Pump the Evacuator Handle several times to create a vacuum. The 

oil will flow through the Suction Hose Assembly into the Reservoir 

until it has all been extracted OR until maximum reservoir capacity 

has been reached. 

5.  Disconnect the Main Suction Hose from the Dipstick Tube Adapter.

6.  Disconnect the Main Suction Hose from the Reservoir Cap. Pour 

the used oil from the Reservoir into a suitable container. Dispose of 

used oil in accordance with federal, state and local regulations. 

EXTRACTING COOLANT FROM A RADIATOR  

OR EXPANSION TANK

WARNING

:

 

DO NOT remove the cap from the radiator or 

expansion tank while the engine is at operating temperature. This 

system is under pressure and could cause serious injury. ALWAYS 

allow the engine to cool completely prior to removing the radiator 

cap or expansion tank cap.

1.  See “Preparing for Operation” instructions above. Allow the engine 

to cool completely.

2.  Remove the radiator or expansion tank cap. 

3.  Insert the appropriate diameter Suction Hose Adapter into the 

radiator or expansion tank until it reaches the bottom. 

NOTE

DO NOT bend the Suction Hose Adapter while inserting the 

Hose Adapter into the radiator.
4.  Connect the Main Suction Hose to the inserted Suction Hose Adapter. 

NOTE

Ensure that the hose connections are tight to prevent leakage 

during the extraction process. 
5.  Press the Main Suction Hose into the Reservoir Cap as described in 

the assembly instructions.

NOTE

Ensure that the Vacuum Release Plug is fully inserted in the 

lower receiving hole prior to operation. If the Vacuum Release Plug is 

not inserted, a vacuum will not be created.
6.  Pump the Evacuator Handle several times to create a vacuum. 

The coolant will flow through the Suction Hose Assembly into the 

Reservoir until it has all been extracted OR until maximum reservoir 

capacity has been reached. 

7.  Disconnect the Main Suction Hose from the Suction Hose Adapter.

8.  Disconnect the Main Suction Hose from the Reservoir Cap. Pour the 

used coolant from the Reservoir into a suitable container. Dispose of 

used coolant in accordance with federal, state and local regulations. 

EXTRACTING BRAKE FLUID FROM THE  

MASTER CYLINDER

1.  See “Preparing for Operation” instructions above.

2.  Clean the exterior of the master cylinder and master cylinder cap to 

prevent dirt and debris from entering the master cylinder when the 

cap is removed.
