Stabiliser Operation

NOTE:
The sta bi lis ers will only func tion when the booms
are stowed. Once the booms are raised the sta bi -
lis ers will not op er ate.
Be fore op er at ing the sta bi lis ers check to see that
the ground con di tions un der the four (4) sta bi -
liser pads is firm, sta ble and un ob structed.
DANGER
If the platform is up and the ground
compresses unevenly under different
stabiliser pads the MHP might tip over
causing serious injury or death. Check the
level bubble frequently during operation. If
any movement of the bubble occurs,
immediately lower the platform and readjust
the stabilisers to re-center the bubble in the
ring
Al ways check that all four (4) feet are clear of man -
hole cov ers, drains etc., which may col lapse. If the
ground is at all soft, steel plates at least 300mm x
300mm x 6mm should be placed un der the feet to
spread the weight.
En sure the boom/sta bi liser switch (item
ground con trol box) (see Fig ure 8.5) is set to sta bi -
liser.
Ac ti vate the sta bi lis ers (see Fig ure 8.3) with the
valve le vers en sur ing that the front sta bi lis ers are
low ered first to pre vent dam age to the jockey
wheel.
Ac ti vate the rear sta bi lis ers and level the ma chine
us ing the level bub ble ad ja cent to the con trol le -
vers.
