• Start the machine, switch the control panel position selector key (con-
trol rep. 15, Photo 1, page 27) to "axles" (pictograms - black circle).
In this position, the controls of the "platform" and "turret" panels are
disabled
• lower lever rep. 1, Photo 7, page 32, to make raise the rear of the
chassis
• When the axle wheels do not touch the ground anymore, lower lever
rep. 2, Photo 7, page 32 to activate the extension of the axle, while
holding lever rep. 1, Photo 7, page 32 abaissée.
• Once the axle is completely extended (the alarm stops sounding), re-
lease lever rep. 2, Photo 7, page 32 then raise lever rep. 1, Photo 7,
page 32until the chassis hydraulic jack is completely retracted
• proceed in the same way with levers rep. 3 and 4, Photo 7, page 32.
Make sure before proceeding with
the retraction of the axles that the

aligned along the axis.
Retracting the axles:
• With the machine folded, switch the control panel position selector
key (control rep. 15, Photo 1, page 27) ) to "axles" (pictograms - black

disabled
• lower lever rep. 3, Photo 7, page 32, page 34, to raise the front chas-
sis.
• When the wheels of the axle do not touch the ground anymore, raise
lever rep. 4, Photo 7, page 32 thus activating the retraction of the
axle, while keeping lever rep. 3, Photo 7, page 32 lowered
• Once the axle is completely retracted (the alarm stops sounding), re-
lease lever rep. 4, Photo 7, page 32 puis lever la manette rep. 3,
Photo 7, page 32 then to raise the lever No. 3, Photograph 7, page 34

correctly positioned: when the machine is positioned on horizontal ground,
the higher stop of the linkage component must be horizontal.
