1. When the lifter is in the required position, secured with the legs and
attached with the front support to attach the load horizontally, is the
time to raise the load coupled.
2. Block ALL theautomatic safety pins (
A system
).
3. Unblock the most external safety pin (
marked 1
) in
B
system
.
4. Turn the winch clockwise, the profile
that incorporates the support with the
load, begin to rise.
Be careful controlling load in each
moment to avoid oscillations.
During this process the bolt of A system
placed in this profile will insert automatically
in the fixation holes, until the elevating process
extract it and continue until the next fixation
hole.
Once you reach the approximate height required,
block the pin, now, rotating the winch a few more
turns, is inserted into one of the holes of the rail.
5. Now proceed in the same way with the second
profile:
Check the bolt (
A system
) in the second profile
is in blocked position and UNBLOCK the bolt
of
system B
(
marked as 2
).
Turn the winch to unfold the second profile

3
6. Finally, deploy the last profile, unblocking the last pin
(
marked as 3
and proceed in the same way as points
4 and 5.
7. The lifter is fully deployed as shown in the drawing on
the next page.
1. For the lifter descent / folding process, proceed in reverse way.
First of all,
UNBLOCK THE A system BOLT in the last profile.
2. Extract the B system bolt (
marked as 3
) and keep it during all profile folding
process. The safety bolt is in blocking position, therefore, simply releasing it,
the profile will be blocked.
3. Turn the winch counterclockwise carefully to avoid load oscillations, which may
be higher due to the height. Once this section reachs the rest position, release
the B system bolt (marked as 3), and continue using the whinch, the bolt will be
inserted in the next fixation hole and the profile will be blocked.
4. Block again the A system bolt of the folded profile.
2. Now we have to descend the next profile. Perform the same operation, unblock
the A system bolt and extract the B system bolt (
marked as 2
) and use the
winch to fold this new profile.
3. Finally, proceed with the first profile unblocking the A system bolt
and extracting the B system bolt (marked as 1) and using the winch to fold
the last profile.
4. Remove the load of the horizontal support.
5. Place the horizontal support arms in the transport position.
6. Check ALL transport bolt (
A system
) will be in block position
7. Remove front and rear legs and insert them into their accommodation.
8. Now the lifter is ready for transport.
