3. Installation

Before installing the Bravo™ AC hoist make the
following checks:
1� Check that the hoist is in good condition�
2� Check that the correct hoist capacity is to be used.
3� Check that the hooks and safety latches are in good
condition�
4� Check that the low limit stop is in place�
5� Check that the load chain is correctly fitted.
6� Check that the anchor point is sufficient to take the
intended load�
After successfully completing the preliminary checks,
install the Bravo™ AC hoist on its anchoring point and
perform the following checks:
1� Check that the Bravo™ AC hoist is properly
suspended by its suspension hook (item 5, fig. 1)
and that the hook safety catch (item 6, fig. 1) is
properly closed (see figs 2 and 3).
2� Check that the load chain has not been subjected to
any torsion when setting up�
3� Without load, check that the "Up" and "Down"
functions operate correctly�
4� When using the hoist with a push suspension
trolley, without load, check that the trolley moves
freely� If using a geared suspension trolley, without
load, check the direction of movement by pulling on
the trolley hand chain. The movement should be
carried out on a strictly horizontal plane.
After successfully completing these checks, place the
load in position and ensure:
1� The anchoring accessory of the load sits fully in the
hook and does not prevent the catch from closing
correctly (see figs. 2 and 3).
2� The load on the hoist is free to align itself with the
machine's anchoring point�

4. Operation

4.1. Operating principle
The Bravo™ AC hoist is operated by means of an
actuating handle (item 7, fig. 1) which is moved back
and forth by the operator to lift or lower a load, pull a
load, or apply tensioning�
4.2. Installing the lifting hook on the load
rigging point
If installation of the lifting hook requires adjustment of
the chain length, proceed as follows:
1� Make sure that there is no load on the chain�
2� Set the movement selector lever (item 1, fig. 4) to
the neutral position "0"�
3� With no load on the machine, turn the load wheel
(item 3, fig. 1) anti-clockwise to open the brake; the
chain is released�
4� If it is not possible to turn the load wheel put the
selector lever in the "D" position (fig. 4) and operate
the lever handle whilst exerting some force on the
hook side of the chain with your hand� Place the
selector lever in the "0" position and pull on the
chain, which is thus released, using the low limit
stop�
5� Secure the lifting hook to the load (or to a fixed
point), or to the point where tension will be applied.
Apply a slight tension to the chain by pulling on the
chain using the low limit stop�
6� Turn the load wheel clockwise; the brake is closed.
The chain is engaged in the hoist�
4.3. Maneuvering the hoist
1� To lift, pull or tension: put the selector lever to "L"
position (fig. 4) and operate the lever handle back
and forth�
2� To lower or slacken: put the selector lever to "D"
position (fig. 4) and operate the lever handle back
and forth�
4.4. Important additional instructions
1� When taking the Bravo™ AC hoist out of service
ensure that there is no load applied and that the
load chain is slack enough to enable the bottom
hook to be removed from the load.
2� The selector lever must not be left in the neutral
position "0" when a load is sus pended or the hoist
is tensioned� Make sure that the selector lever is
in the desired position and is not located between
two positions�
3� Do not attempt to operate the load wheel during any
operation or when a load is suspended on the hoist�
4� is not recommended to operate the lever handle
at excessive speed as this will lead to an uneven
movement of the load� It is recommended to
operate the lever handle in a steady movement to
prevent any unnecessary jerking of the load�

5. Storage

It is recommended that the hoist be stored hanging so
that the load chain does not become tangled. Store the
hoist in a dry and weather-proof area� Before storage
clean the load chain with a brush and lubricate with
machine oil�
