The inner boom nose section has an attachment carry-
ing device feature called Dynattach
®
system. This pro-
vides the operator with a convenient means of utilizing
optional attachment tools. Refer to the OPERATION &
ADJUSTMENTS chapter for changing attachment
tools procedures.
Once the operator tilts the attachment tool to a desired
angle, that angle will be maintained as the boom is
raised or lowered, extended or retracted, until a new
angle is desired.
To tilt the attachment tool, move the joystick handle
rearward to tilt the attachment tool up. To tilt the
attachment tool down, move the joystick handle for-
ward.
Boom Joystick:
This machine has a hydraulic type
boom with telescopic sections. The sections extend by
means of a hydraulic cylinder (Model 552) or
hydraulic cylinder and chain system inside the boom
(Model 553), sequenced for uniform extension of each
section.
To extend the boom, move the joystick handle to the
right. To retract the boom, move the joystick handle to
the left. To raise the boom, move the joystick handle
rearward. To lower the boom, move the joystick handle
forward.
Boom Angle Indicator:
Mounted on the left side of
the outer boom. The position of the bubble in the
Boom Angle Indicator, shows the angle of the boom
relative to the ground surface.
Optional Attachments Joystick:
For other attachment
options which require additional hydraulics, a 2-posi-
tion joystick is provided.

WARNING
Use extreme caution when raising or extend-
ing the boom. The Telescopic Forklift MUST be
level. Loaded or empty, this machine can tip if
not level.
ALWAYS place the transmission in neutral, set
the parking brake switch and keep the service
brake pedal fully depressed before raising or
extending the boom.
NEVER exceed the specified lifting or extend-
ing capacities of this machine. Serious
machine damage or personal injury may
result. Refer to the load zone charts in the
operator’s station or this manual.
If a boom circuit hose should break with the
boom up, with or without a load, shut down
the machine following the MANDATORY
SAFETY SHUTDOWN PROCEDURE. DO NOT
attempt repairs. Call your GEHL dealer imme-
diately for assistance.
The truss boom and winch attachment tools
should ONLY be used to lift and place loads
when the machine is in a stationary position.
DO NOT use to transport loads around the job-
site. This can cause the load to swing, result-
ing in either load dropping or machine tipover.
NEVER use winch for lifting or moving per-
sonnel. NEVER exceed the maximum rated
capacity of the winch (3000 lbs., 1360 kg) or
exceed the load chart rating for winch appli-
cations.
DO NOT tilt the truss boom back more than
45
o
from horizontal. DO NOT attempt to use
the rotating carriage as a load leveling func-
tion. Always level the frame prior to raising a
load.
Failure to heed could result in death or seri-
ous injury.
