tools when operating the locking devices, e.g. using the supplied key (C)!
Also see "3.7 Changing between transport position and working position" on page 26.
The drill has a function that allows the wheels of the side sections to be retracted when the machine
has been folded in to the transport position. This further reduces the transport width of the ma-
chine.
To engage this feature, move the levers (A) (one on each side section) up to position (B) once the
machine has been folded in. Use a suitable tool, such as the supplied key (C).
When the machine is unfolded to the work position, the wheel retraction mechanism is automati-
cally reset and the wheels return to the "normal" position.
! The drill should not be in the fully raised position when the side sections are unfolded. Lower
it approx. 5 cm from the topmost position prior to commencing folding out the machine.
! If automatic resetting of the wheel retraction mechanism does not operate, this can be verified
by the machine hanging at an angle in the folded out position. If this is the case, fold in the side
sections and repeat the folding out procedure.
! The machine can be folded in and unfolded even when this feature has not been engaged. How-
ever, the result will be that the wheels of the side sections then remain in the "normal" position,
and the transport width will accordingly be slightly wider!
! Do not lower the machine to the drilling position if the machine is resting on soft ground and
the side sections have been folded in with the side section wheels also retracted.
If the machine has been folded in with the side section wheels retracted, do not retract the
wheels from the ground using the hydraulics.
Unless this caution is heeded, there is a risk of serious mechanical damage to the drill.
