Before operating the stabilisers check to see that
the ground conditions under the four stabiliser pads
is firm, stable and unobstructed.
! DANGER
If the platform is up and the ground
compresses unevenly under different
stabiliser pads the MHP might fall 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.
When using the stabilisers always check that all
four are firmly on the ground and that they are
clear of manhole covers, drains, etc., which may
collapse. If the ground is at all soft, steel plates at
least 300mm x 300mm x 6mm should be placed
under the feet to spread the weight.
! DANGER
Death or serious injury can result if an MHP
tips over. Do not use the stabilisers to gain
extra working height, they are not designed
for that purpose. At least one of the stabilisers
should raise the MHP above the ground - use
the other three to level the MHP as necessary.
NOTE: Operating the Stabilisers
Before you can operate the stabilisers you need
to start the engine. See “Starting From Ground
Control Box” on page 3.
❑ Using the manual stabiliser valves
Ensure the Boom/Stabiliser Switch (item Πon
the ground control box) (see Figure 8.7) is set to
stabiliser.
Activate the stabilisers with the valve levers
(down-wards). (see Figure 8.3)
NOTE:
Ensure that the front stabilisers are lowered first to
prevent damage to the jockey wheel.
Figure 8.3
Lower the rear stabilisers and level the machine
using the level bubble (see Figure 8.4) adjacent to
the control levers.

! WARNING
When levelling the machine in either the
manual or automatic mode care is required
to ensure that all the foot plates are firmly
on the ground, the machine is level and the
lift enable light is on before entering the
platform.
❑
Raising the manually operated stabilisers
Raising the stabilisers is the reverse of setting the
stabilisers.
Ensure that the Boom/Stabiliser Switch is is set to
stabiliser.
Raise the stabilisers by activating the individual
valve levers (upwards).
NOTE:
Ensure that the rear stabilisers are raised first to
prevent damage to the jockey wheel.
