Checks before
starting work
When the ignition is turned on, ECOS registers the displayed telescoping
status from the current status of the telescoping mechanism and the
previously saved locking and unlocking procedures.
Normally, ECOS detects differences between the current and the displayed
telescoping and displays the corresponding error message;
à Telescoping
mechanism error messages
, p. 14 - 17.
If a malfunction results in values being deleted, ECOS can no longer calcu-
late the current telescoping and will not issue an error message.
• Before telescoping the first boom, compare the telescoping shown on the
ECOS display with the current telescoping.
If the current telescope status is not correctly displayed, enter the current
telescope status;
à Entering the current telescoping, p. 14 - 53.

Risk of damage to the telescoping mechanism
Before the first telescoping, always check whether the
ECOS display is
showing the current telescoping.
This prevents the telescoping mechanism from being damaged when tele-
scoping.
