2. Then install appropriate connection adapters to the engines delivery and return lines. You are now able to connect the Injecto-
Clean unit's delivery and return to the corresponding connection adapters at the engine.
3. Add at least two cans of 938 Injector Intensive Cleaner (initial filling) through the appropriate filling connection into the Injecto-
Clean unit (internal can pressure performs filling). Attention: Open red cap for filling. On engines with eight cylinders or more or
displacement greater than 3000 ccm, add three cans for initial filling. Use one or two cans for refilling. Connect the Injecto-Clean
unit at the corresponding power-supply terminal to the vehicle's 12V battery (observe proper polarity). Close up filler coupling
with red cap, after work and for transport.
4. Switch on the Injecto-Clean unit's power switch and use the pressure regulator to set the correct fuel pressure (1 bar for pump-
nozzle engines or up to 3.5 bar for common rail engines). Start the vehicle and allow to idle for approximately 20 minutes with the
938 Cleansing Fuel. After 20 minutes, turn off the engine and allow the 938 Cleansing Fuel to work for at least 30 minutes but no
more than 60 minutes. Then restart the engine and allow it to run for an additional 20 minutes at alternating revs (maximum 2500
rpm).

5. Shut off the engine and allow the fuel system to cool down. Separate the hoses of the Injecto-Clean unit from the connection
adapters at the quick connectors. Attention! A small amount of cleansing fuel may escape from the connection adapters. Please
capture this fuel with an appropriate means, e.g., paper towels or cloth. Remove connection adapters from delivery and return
lines. Reconnect the vehicle's fuel supply and check for leaks. Reset the fuel adaptation values in the engine control device.
6. Start engine and allow it to idle for several minutes. Delete any error codes that appear. Check fuel system connections for leaks.
Replace fuel filter (item No. 11 13310-12) in the return line of the Injecto-Clean unit.
7. If the unit will not be used for longer than two days after the most recent cleaning or if a gasoline-powered vehicle will be cleaned
next, the unit's tank and the connection lines must be completely drained. To do this, place the connection pieces onto the delivery
and return lines of the Injecto-Clean unit and place them in a suitable container (min. 1 liter). Switch on the unit and pump out the
residual liquid until nothing more comes out of the hoses. Switch off the unit, remove the connection pieces from the delivery and
return lines. Disconnect Injecto-Clean unit from the battery (observe proper order). Close up vent and filler coupling with red cap.
