CAUTIONS ON DEF/COOLANT PIPING ATTACHING AND DETACHING
(1)
If the quick joint used in the DEF piping is once removed, DEF powder precipitates on the seal area and leakage may
occur after reconnection. Before reconnecting, thoroughly check the seal area for deposition of DEF powder and
other foreign matter. If deposition of DEF powder is found, wash it with hot water.
(2)
If you perform work with after-run not finished, DEF filled in the pipe will flow out when the quick connector is discon-
nected. Be sure that after-run is finished.
NOTICE
DEF is remained in the DEF pump and pipe in the condition where DEF injection is finished. After-run is a system
which brings DEF back to the DEF tank after the engine is turned off so that remaining DEF will not be frozen in
cold weather or dried and crystallized.
(3)
If you perform work immediately after the engine is stopped, hot coolant may spout and you may get burned. Before
performing work, be sure that engine coolant is thoroughly cooled.
(4)
Do not apply an excessive force to tubes when working since formed tubes are used for piping.
(5)
Do not directly touch DEF or coolant flowing out from the pipe. If you have touched it, thoroughly rinse it out.
(6)
After removal, place a plastic cover to avoid entry of foreign matter into the pipe.
(7)
Place the cover immediately after removing the joint to avoid entry of foreign matter into the DEF tank, DEF pump,
and DEF injector.
(8)
When covering, use separate covers to avoid mixing of DEF and coolant.
(9)
If removal is difficult, do not apply an excessive force since it may damage the quick connector but remove dust
adhered around the joint and remove the quick connector.
(10) The coolant pipe and DEF pipe are assembled for piping but do not disassemble it.
(11) Do not use tools when disconnecting the quick connector.
(12) Perform work with all the harness connectors fitted. If you perform work with connectors removed, rusting may result.
Cover the connectors to avoid splashing of coolant and DEF.

REMOVING THE QUICK CONNECTOR
(1)
Press the lock from both sides to remove the quick connector.
! CAUTION
•
It may get damaged if it is not removed by properly pressing in the lock.
•
Do not force open with a screw driver and other tools.
3.
MOUNTING THE QUICK CONNECTOR
(1)
Check that no dust or dirt remains on the connector end when mounting the quick connector. Clean deposits, if found,
with hot water. Mount the quick connector securely until it makes a click sound.
! CAUTION
When crystallized DEF is adhered to the DEF piping, remove the crystals by a waste soaked in warm water or
wash it off by warm water.
