It is important to read this paragraph carefully as it contains important information on the risks to which the operator exposes
himself / herself by using the lift incorrectly. Please find hereafter the information to enable the user to avoid dangerous
situations.
WARNING
This lift was d sign d to lift v hicl s up and to maintain th m in a sp cific position in a cov r d workplac .
Any oth r us is forbidd n
In short, the lift is not suitable for the following uses:
-washing and spraying operations
-use as traction equipment
-use as a goods lift
-use in an area where there is a danger of explosion (spray booths, etc), except for special versions. (ATEX)
The floor on which the lift is placed should be sufficiently strong to support the weight of the lift, the load deck and the load,
with a safety margin of 25%;
The concrete floor must have a minimum thickness of 150mm and a minimum resistance of C20/25 (Norm EN206-1)
Any masonry work required should be studied by a design office and carried out by a masonry company, authorised to carry
out such work and projects.
The lift can be recessed into the floor (refer to the drawings covering the foundation works). The lift must be fixed using the
"rawlplugs" provided or equivalent anchors.
The manufacturer will not take into account any request for compensation for injury or material damage (vehicle or other
goods) in the event of improper and / or unauthorised use of the lift.
During raising and lowering the operator must remain inside the operating area (2) as defined in Figure 1. Entry into the
safety area (1) is strictly forbidden. The presence of a person under the vehicle is only authorised when the lift is in its fully
raised position.
Figure 1

STL27 – STL28
4
During lifting the operator should ensure that the load does not present any risk; after raising the vehicle a small amount he
should stop and check that it is correctly positioned before continuing.
THE OPERATOR should check the load and the loading platform during raising and lowering.
It is forbidden to climb on the load or the loading platform when they are raised.
Never start the vehicle when it is raised, even a little, or before the lift is completely lowered.
Figure 2
Never use the lift unless all the safety systems are working properly. Failure to follow these rules may result in serious injury
or irreparable damage to the vehicle lift and / or to the vehicle placed on it.
GENERAL PRECAUTIONS:
-The operator must follow the regulations in force in the country in which the lift is installed.
In addition, the operator must:
-Always work in the operating area in accordance with the instructions in the manual.
-Never remove the protective covers or dismantle or close the mechanical, electrical or other safety systems.
-Read the safety regulations applying to the lift and the safety instructions in the manual.
The following terms are used in the manual to describe the types of risk:
DANGER : for the possibility of a risk that could cause serious injury or death
WARNING : describes situations and / or actions that could cause injury or but not death
CAUTION : describes situations and / or actions that are dangerous and likely to cause slight injury and / or damage
to the lift, the vehicle or other goods
RISK OF ELECTRICAL DAMAGE : the lift has specific safety equipment installed in areas of high risk.
RISK AND MEANS OF PROTECTION : these are risks to which the operator is exposed when the vehicle is
in the raised position, and the means of protection installed to minimise any dangers.
WARNING
Do not mov th v hicl wh n rais d on th platform. R mov th platforms and th rubb r acc ssori s only wh n
th lift is in th low st position and not load d.

STL27 – STL28

The vehicle should be positioned on the lift so that the load is evenly distributed over the platform.
SAFETY DEVICES
The following safety devices are installed to prevent damage or overloading:
-DEAD MAN SYSTEM
The lift is fitted with "dead man" type controls. Raising and lowering movements, controlled by push buttons, stop immediately
if the button is released.
-FOOT PROTECTOR
A safety device that automatically stops the movement approximately 20 cm from the floor.
-A SELF-REGULATING FLOW LIMITER THAT CONTROLS DESCENT SPEED
-SAFETY SOLENOID VALVES
A dual hydraulic circuit comprising 3 solenoid valves
-PRESSURE RELIEF VALVE
An excessive load on the lift causes the pressure relief valve to open.
-MOTOR THERMAL PROTECTION
Cuts off the power supply in the event of an overload.
RISKS FOR PERSONS
This paragraph describes the risks to which the operator, or any other person in the vicinity of the operating area, is exposed
by inappropriate use.
Never leave accessories or other objects against the platform and never place objects on the platform when it is loaded, as
this could hinder the operation of the lowering mechanism, and possibly cause the vehicle to fall (Figure 3).
figure 3
Blackhawk uses the highest quality materials for its lifts to guarantee their safety. They should be used in accordance with the
specified criteria and be regularly maintained.
RISKS LINKED TO USE AND MAINTAINANCE
Blackhawk uses the highest quality materials for its lifts to guarantee their safety. They should be used in accordance with the
specified criteria and be regularly maintained.
RISKS LINKED TO THE POSITION OF THE VEHICLE
This type of risk can arise if the vehicle is not properly positioned on the rubber pads (Figure 4), or if the platforms are not
correctly aligned in relation to the vehicle. Always use the lift points specified by the vehicle manufacturer and position the
vehicle as close as possible to the centre of the platform.

INSTALLATION PROCEDURE
1. Ch cking th l ctricity supply
First, make sure that the power supply is fitted with a magneto thermal protection switch (380V – 16A with a protective fuse)
and appropriate protection devices conforming to the electrical safety regulations in force.
2. Positioning th lift
When installing the lift take into account the size of the vehicles to be lifted, and a minimum distance of 500 mm between the
walls and the lift.
-Sufficient space for the operators.
-Sufficient space for maintenance and for entry and exit routes.
-Positioning in relation to other machines.
-Position of the console unit at a minimum 3m from the lift.
-The position of the console should allow the operator to observe all the movements of the lift.
Use a fork lift truck, crane or other appropriate lifting means to position the lift.
If the lift is being installed in a pit, make sure that the lift is correctly centred in the pit. If the floor is not level (up to 3mm), fill
the gaps with metal shims.
3. Anchoring th lift
The minimum resistance of the concrete floor the lift is installed on must be C20/25, and the minimum
thickness 150mm.
Use all the bolts supplied to fix the lift to the floor
•Using the base as a template, with a Ø 16 mm drill, make a hole in the floor to a depth of approximately 120 mm.
•Clean the holes and insert the 8 "rawlplugs" supplied, using a hammer but without hitting them hard.
•Before tightening the rawlplugs finally, check the perpendicularity between the vertical axis of the lift and the floor.
•Tighten the rawlplugs with a torque wrench (tightening torque 50 Nm).
3. Conn ctions to th lift
WARNING
B for any work on th control unit to mak l ctrical conn ctions or r pair faults, mak sur that th pow r is
disconn ct d to pr v nt any dang r of l ctrocution.
The lift has 3 adjustable limit switches F1, F2, F3. (Figure 17)
Limit switch F1 has the function of protecting the feet; it stops the platform descent at approximately 200mm from the floor
Limit switch F2 has the function of stopping the ascent of the platform approximately 10mm from the floor (in floor versions) to
allow the arms to be opened.
Limit switch F3 has the function of stopping the descent of the platform approximately 10mm from the floor (in floor versions)
to allow the arms to be closed
