4. USER INSTRUCTIONS.
4.1 - Place the lift on a firm, flat surface
in the area it is to be used with the help of
the transport wheels (T).
4.2 - Remove the legs (P) from their trans-
port compartment (S) and fully insert them
into their working positions (V) checking
that they are fixed by the pins (R). Remo-
ve the reinforcement struts (A) as well and
place them in their anchor points (E), fix
them with their corresponding pins and
clips.
4.3 - Check that the lift is in vertical posi-
tion using the spirit level (L) at the base of
the tower, adjust the stabilizer of the legs
(Q1), turning the handle (H) if necesary.
Finally, adjust the base stabilizer (Q2)
until it touches the floor.
4.4 - Release the forks (F) and place them
in its working horizontal position ready to
take the load on them. Insert the pins to
block the forks.
4.5 - DO NOT OVERLOAD THE LIFT.
MAXIMUM LOAD IS 400 kg (881.9 lb)
The lift should NEVER be overloaded.
Safety at work is the most important is-
sue. Place the load onto the lift using an
PRO LIFTS S.L.

ENGLISH
adequate VMB support according to the
need, use so that the weight of the load
will only be elevated in a vertical direction.
The minimum load is 25 Kg.
4.6 - How to place the load: Always load
as close to the tower as possible.
The maximum load diminishes according
to the distance from the body of the tower
as illustrated in the diagram 4.6.1, which
shows the load on the gravity centre with
distances to the lifting carriage at a maxi-
mum lifting. Use a VMB adaptor if neces-
sary.
CAUTION
When two towers are used to elevate a
truss bridge, or many towers to elevate a
structure of any type, it is almost impos-
sible that two or more people co-ordinate
the winches elevating or lowering the
loads, at exactly the same pace. At a cer-
tain point each tower will be extended to
different height. For this reason it is ne-
cessary that the structure does not stretch
and allows for these differences.
With a rigid fixation and if the level diffe-
rence is significant, the force generated
from the handle of the winch will deform
the structure and apply a lateral force to
the lifts causing them to break and block.
