6.2.3 Trouble shooting for coolant preheater
In the event of a mal function, fuses and electrical connections should be checked for proper condition
and security.
If this action does not correct the failure, consult with your authorized Webasto dealer.
After the heater has been shut down due to a fault lock-out, coded flashing signal is emitted through
the operation indicator during the after-run cycle of the heater. These coded flashing signals are
designed to assist the authorized Webasto dealer in isolating the fault.

6.3 Operator cabin
Operator cabin provides clean and safe operation by isolating operating area. Cabin can be supplied
as option kit.
DANGER!
Installing cabin on the machine will break weight balance of machine. Do not travel the
machine when cabin is installed on.
Before installing cabin, extend outriggers for supporting machine correctly.
WARNING!
