Checking
• Remove the heat shield (6).
• Check the exhaust system (2) for damage,
from the engine (1) through the DOC cata-
lytic converter with DPF particle filter (5), the
AdBlue mixing pipe (3), the SCR catalytic
converter (4) up to the end pipe.
The exhaust pipes (2) may not have any
loose clamps, holes or cracks.
• Check that the area around the exhaust
pipes is free of loose components which
could burn by coming into contact with the
hot exhaust system.
• Check the mixing tube (3) at the inclined
filler neck for injecting AdBlue for external
damage.
After checking
• Start the engine.
• Check the symbol for the AdBlue system on the instrument panel and the
CCS (C rane Control System) control unit; à p. 7 - 40.
• Check whether exhaust gases are leaking from any damaged places in the
exhaust system.
• Switch the engine off and allow it to cool down.
• Attach the heat shield (6).
If you discover any damage
Have any damaged parts of the exhaust system replaced immediately by
Manitowoc Crane Care or an authorised GROVE dealer.
