FLUID EXTRACTOR/DISPENSER
Extracting from and dispensing uid into transmission cases and differentials
1. Follow Steps 1 & 2 above. (See Extracting and Dispensing Motor Oil into a Crankcase)
2. Remove the transmission uid dipstick or ll plug.
Warning:
In some applications this may require jacking or lifting the vehicle. Use appropriate safety stands to avoid serious
or fatal injury.
3. Select and insert the appropriate diameter dipstick tube into the dipstick ll hole until it reaches the bottom of the
transmission pan or gear case. Connect the main suction tube to the dipstick tube.
4. Insert the opposite end of the main suction tube into the 10mm x 90° tube connector on the top of the reservoir
tank. Take care that tube is in the connector all the way to prevent leakage.
5. Place the selector valve mounted on the side of the pump assembly to "EVACUATE".
6. Raise the pump handle on the reservoir tank until it reaches its highest limit. Pump the handle approximately ten
times. The unit will begin to extract the transmission uid from the transmission.
7. Once the transmission uid has been extracted, remove the expandable rubber plug from the reservoir tank; pour
the transmission uid from the tank into a suitable container, and dispose of the transmission uid in an appropriate
manner. Rinse out the reservoir tank with clean solvent or engine degreaser.
Allow it to dry thoroughly.
8. If you wish to use HU 0631 to dispense transmission uid, ll the cleaned reservoir tank with new transmission
uid and simply switch the selector valve that is mounted on the side of the pump assembly to "DISPENSE".
9. Pull up on pump handle and continue pumping until the transmission is lled to the desired level.
10. Follow the operating instructions for your vehicle to properly check the transmission uid level.
Extracting and dispensing coolant into a cooling system
Warning:
Never remove the cap from the radiator or expansion tank while the engine is at operating temperature. Always
allow the engine to cool before removing the radiator cap or expansion tank cap. The cooling system is under
pressure. Failure to allow the engine to cool before attempting to remove the cap could result in serious injuries.
1. Allow the engine to cool.
2. Remove the radiator/expansion tank cap.
3. Select the largest diameter dipstick tube and insert the tube into the radiator neck or expansion tank.
4. Insert the opposite end of the main suction tube into the 10 mm x 90° tube connector on the top of the reservoir
tank. Take care that the tube is in the connector all the way to prevent leakage.
5. Place the selector valve mounted on the side of the pump assembly to "EVACUATE".
6. Raise the pump handle on the reservoir tank until it reaches its highest limit. Pump the handle approximately ten
times. The unit will begin to extract the coolant from the cooling system.
7. Once the coolant has been extracted, remove the expandable rubber plug from the reservoir tank; pour the
coolant from the tank into a suitable container, and dispose of it in an appropriate manner. Rinse out the reservoir
tank with clean solvent or engine degreaser. Allow it to dry thoroughly.
8. If you wish to use HU 0631 to dispense coolant from HU 0631, ll the cleaned reservoir tank with new coolant
and simply switch the selector valve that is mounted on the side of the pump assembly to "dispense".
9. Pull up on pump handle and continue pumping until the cooling system is lled to the desired level.
10. Be sure to run the engine until it reaches operating temperature to circulate the new coolant and then re-check
the level to be sure that it is full.
