using. lf wear or cracks are found, reDlace the hoses
before using.
4.
Using the measuring cup. fill the tank with 2,1 ounces(approximately 2/3 full) of biodegradable flushingfluid (J35944 - 20). Do not substitute with any otherfluid. Follow the handling procedure on the fluidcontatner.
Secure the flusher filler cap, and pressurize the tankwith compressed air to between 5S0 - 829 kpa (5.6 -
8.45 kgf/cm', 80 - 120 psi).
NOTE: The air line should be equipped with a watertrap to ensure a dry air system,
Hang the tool under the vehicle.
Attach the tank's discharge hose to the return lineoi the transmission cooler using a clamp.

7. With the water and air valves off, attach the water andair supplies to the flusher. (Hot water if available.)
8. Turn on the flusher water valve so water will flowthrough the cooler for 10 seconds.
NOTE: lf water does not flow through the cooler, itis completely plugged, cannot be flushed, and mustbe replsced.
9. Depress the trigger to mix the flushing fluid into thewater flow. Use the wire clip to hold the trigger down.
'10. While flushing with the water and flushing fluid fortwo minutes. turn the air valve on for five secondsevery 15 - 20 seconds to create a surging action.AIR PRESSURE: MAX 845 kpa (8.45 kgflcmr, 120 psi)
11. Turn the water valve off. Release the trigger, thenreverse the hoses to the cooler so you can flush inthe opposite direction. Repeat steps 8 through 10.
12. Release the trigger. and rinse the cooler with wateronly for one minute.
13, Turn the water valve off, and turn off the water supply.
'14. Turn the air valve on to dry the system out with airfor two full minutes or until no moisture is visibleleaving the drain hose.
CAUTION: Rosidual mobturo in the qooler or linescln damage the transmission,
15. Remove the flusher from the cooler line. Attach thedrain hose to a container.
16. Install the transmission. and leave the drain hoseattached to the cooler line.
