switch and push the main boom telescoping switch
to the right – the main boom will be extended.
4. Retract the main boom: Move and hold the enable
switch and push the main boom telescoping switch
to the left – the main boom will be retracted.
5. Raise the articulated boom: Move and hold the
enable switch and push the articulated boom luffing
switch upwards – the articulated boom will be
raised.
6. Lower the articulated boom: Move and hold the
enable switch and pull the articulated boom luffing
switch downwards – the articulated boom will be

Perform operation from the platform:
Note: When operating from the platform, the speed of
main boom luffing is in direct proportion to the travel dis-
tance of the handle. The shorter the travel distance, the
slower the speed.
1. Raise the main boom: Depress the foot switch
and push the main boom luffing/turntable slewing
control handle forward – the main boom will be
raised.
2. Lower the main boom: Depress the foot switch
and pull the main boom luffing/turntable slewing
control handle backward – the main boom will be
lowered.
3. Extend the main boom: Depress the foot switch
and pull the main boom telescoping switch down-
wards – the main boom will extend.
4. Retract the main boom: Depress the foot switch
and push the main boom telescoping switch up-
wards – the main boom will retract.
5. Raise the articulated boom: Depress the foot
switch and push the articulated boom luffing switch
upwards – the articulated boom will be raised.
6. Lower the articulated boom: Depress the foot
switch and pull the articulated boom luffing switch
downwards – the articulated boom will be lowered.
7. Extend the articulated boom: Depress the foot
switch and push the articulated boom telescoping
switch upwards – the articulated boom will extend.

For machines equipped with HV mode functionality: if
the main boom is raised by more than 10° the HV mode
indicator will flash slowly, indicating that the HV mode
can be activated. Move the HV mode enable switch –
the main boom will change into HV mode. In HV mode,
any movement of the main boom movement switch will
cause the main boom to start raising/lowering vertically
or extending/retracting horizontally.
NOTICE
• In HV mode, the speed of the main boom’s vertical
and horizontal movements cannot be adjusted.
• In HV mode, the machine cannot perform main
boom luffing and telescoping operations simulta-
neously. The main boom will stop moving if the op-
erator attempts to perform simultaneous
movements.
