ASSEMBLY AND ANCHORING
6-8 MSHF • 7295-026A
6.3.3 Mast climbing work platform with
two masts on a chassis
One drive unit must be adjusted
for "left" and the other for "right".
1. Check that the left-hand machine is
adjusted for "left" and the right-hand
machine for "right". See section 6.7.
2. Position the chassis parallel to the
wall and with a separation to allow for
the required distance between the
masts + 1 metre / 3.3 ft.
3. Withdraw the outriggers on the step
side completely and secure them.
The outriggers on the side facing the
wall should be withdrawn as far as
possible.
The maximum freestanding height
depends on the position of the
telescopic arms and the loading (See
loading diagram, chapter 1.5).
4. Place the ground supports for this
chassis.
5. Unscrew the jack for this chassis until
the wheels no longer touch the
ground and level the machine. The
measurement must be done with a
spirit level with a minimum length of 1
meter / 40 inch.
6. Check that the autolevel locking pins
and the lower striker plates are
mounted on both chassis.
