Diesel Cleaning Procedures

1. Verify that Mixture, Priming, and Diesel Setup Procedures above have been

completed before continuing.

switch on after turning TIMER past five minutes. NOTE: Alarm will sound until pump

FUEL PRESSURE gauge. Check all connections

for leaks and correct as necessary.

Check for fuel leaks and correct as necessary.

5. Once the unit and engine are running, the run time can be adjusted. The default run time is 60

minutes.

Soak Mode

Use of the Soak Mode Cycle improves fuel system cleaning results, but it may be

bypassed if a shorter service is desired.

1. After 20 minutes of operation or half of the run time, whichever is less; a Soak Mode can be

initialized.

2. Shut down engine. Then press off the unit’s ON/OFF switch. NOTE: This will shut

down the pump and fuel supply to engine, so it is very important

that engine be shut

down first.

3. Let fuel mixture soak in engine for at least 15 minutes. Turn TIMER past five minutes. Turn

the

ON/OFF switch on. Press and hold the START/RUN switch to restart the unit and build

pressure.

4. Continue on with the cleaning mode. Reset the

TIMER to the time last shown before the

Soak Mode was initialized. Restart the engine. The cleaning cycle will continue for the

remaining run time.

NOTE

Additional Soak Cycles can be initiated by repeating

steps 2 through 4 as many times as needed.
