10. OPERATION OF THE BOOMS
Before starting to lift the booms:
1. Make sure that all four outriggers are on solid ground, the machine has been
levelled correctly and that the green indicator that allows lifting of the booms
is lit. If the green indicator is not lit and one tries to lift the booms the
engine/motor stops and will not start before the booms have been lowered
down to transport position by using the emergency lowering buttons.
2. Turn the function selector switch no. 2 at platform to boom operation position.
3. Adjust the hand throttle to slightly more than idling.
4. The booms are operated with the control levers of the boom control valve at
platform
– or with the control levers of lower controls, if fitted.
5.
When the indicator ”<135 kg” at platform (no. 8, see page 14) is lit, the
booms can be operated over the whole working area. If the indicator is not lit,
the outreach of the booms is restricted
– in this case the telescopic boom
comes out about 1 meter and then the movement stops.
When the load at platform is under 135 kg, the ”<135 kg” indicator must be lit,
no matter what the position of the telescopic boom is. If the indicator is not lit
– or then it is lit all the time, operation must be stopped and function of the
indicator and the system must me checked.
6.
LEGUAN 125
is also equipped with an overload control system which
prevents boom movements in case the 200 kg safe working load is exceeded,
or in case the telescopic boom comes out more than allowed when load on
the platform is over 135 kg. Should this happen, there is an audible warning
signal and an indicator lights up at the control panel
.
The booms can be
operated again after the overload has been removed from the platform, and
the ignition switch has been turned
to ”0” position – that is the motor/engine
has been stopped and restarted.
ATTENTION! If the <135 kg red indicator is not lit, and the green strip on the telescopic
boom comes out more than 300 mm, operation must be stopped immediately and
Leguan service must be contacted. RISK OF TIPPING OVER!
Thanks to the fully hydraulic controls boom movements are very smooth, exact and stepless.
Operate the control levers with ease and without hesitation
– learn to operate the booms
precisely.
Platform self levelling system keeps the bottom of the platform automatically level.
ATTENTION!
If the level position of the platform must be adjusted
– for instance in case the
machine has not been used for a long time and the platform has tilted
– operate the control
lever of platform self levelling carefully, especially when the booms are up.
ATTENTION! Always lift the lower boom first from transport support before operating
other movements. When lowering the booms make sure to drive them straight down to
transport supports.
