GRT9165 OPERATOR MANUAL OPERATING PROCEDURES
and “set down” the boom section. After the boom section
has been locked the symbol to unlock cylinder appears.
If the operator selects the symbol to unlock the
telescoping cylinder it will disengage the boom section
and move to the next boom section. When it arrives at
the next boom section it will lock the cylinder to the
section and then unlock the boom section from the
neighboring boom section automatically.
• Emergency Mode is used to move the telescoping
system for maintenance and service work, as well as
when a problem occurs that affects the other telescoping
modes. The Emergency Mode has two levels of access.
The first level is the basic emergency mode, which is to
be used to service or repair the pinning head. The basic
emergency mode can only be used to extend a fully
retracted boom for the purpose of aligning the pinning
head with the hole in the base section. Moving the boom
for all other reasons must be done in the extended
emergency mode, which requires a special access
code. In the Emergency Mode the operator has control
over the locking and unlocking functions of the
telescoping cylinder. The operator can also retract or
extend the telescoping cylinder. The operator or
technician may also see the sensor information for the
complete telescoping system.
The operator must use the telescope controller with the
automatic and manual telescope modes in the ODM to
telescope the boom.

return to the center (neutral) position to stop extending
the boom.
Single Axis Controller (Optional)

DANGER
Crushing Hazard!
Check Load Chart Manual for maximum load at a given
radius, boom angle, and length before extending boom
with a load.
DANGER
Two-Block Hazard
To avoid death or serious injury, keep load handling
devices away from the tip of the boom or boom extension
when extending or lowering the boom and when hoisting
up.
When extending boom, simultaneously let out hoist rope
to prevent two-blocking the boom nose and the hook
block.
