FOLLOWED, SERIOUS INJURY COULD BE CAUSED TO PEOPLE AS WELL AS IRREPARABLE DAMAGE TO THE
LIFT AND THE VEHICLE ON THE LIFT.
GENERAL PRECAUTIONS:
-The operator is bound to follow the regulations which apply in the country in which this lift is installed.
In addition, the operator must:
-Always work in the “OPERATOR AREA” as designated in the manual.
-Never remove the protective guards or dismantle or shut down the mechanical, electrical or other types of
safety arrangements.
-Read the safety regulations related to the lift and read the safety information provided in this manual.
The following terms have been used in this manual to describe the various types of risk:
DANGER: there is a direct possibility of danger which could lead to serious injury or death.
WARNING: indicates situations and/or actions which are unsafe and could lead to injuries of various types
except death.
CAUTION: indicates situations and/or actions, which are unsafe and could lead to light injuries to persons and/or
damage to the lift, the vehicle and other properties.
RISK OF DAMAGE DUE TO ELECTRICITY: special safety arrangements have been made on the lift
in places where the risks are very high.
RISK AND PROTECTIVE MEDIA: the risk to which the operator is exposed when the vehicle is in a raised
position, together with the protective media which have been installed, in order to limit the possible dangers.
WARNING
Non suitable lighting may be risky. Ensure that all areas next to the lift are well lit in a uniform manner.
The vehicle must be placed on the lift in such a way that there is a uniform distribution of weight over the platforms.
To ensure the safety of persons and equipment, you must make sure that:
-The “DANGER AREA” is kept under observation during the lifting process
Climbing on the platform when lifting the vehicle or when it has already been raised is strictly forbidden.

SAFETY DEVICES
The following safety devices have been installed to prevent overloading and damage.
-A hydraulic protection (parachute valve) prevents descending in case of hose fracture.
-Thermal protection switches the power off in case of overloading.
-Overpressure relief valve offers protection against damage due to excessive lifting.
-A foot safety device that automatically stops the lowering at approx.20cm from the floor.
-The lift is fitted with a dead-man control device. Releasing push button controls situated on the console
immediately stops lowering and lifting operations.
-A mechanical locking of the lifting arms rotation.
-A mechanical safety device.
RISKS TO PEOPLE
This paragraph describes the risks to which the operator or any other person near the working area where the lift is in
operation are exposed, if the lift is not used in the appropriate manner.
Never rest any fittings or other objects against the platform and never place such objects under the platform when there
is a load on it, since this can impede the lowering operations and may cause the vehicle to fall off the platform. (Figure 2)
Figure 2
RISK OF USE / MAINTENANCE
BLACKHAWK® uses material of the highest quality in its lifts. These must be used according to the standard specified,
and maintenance must be carried out regularly.
RISKS INVOLVED IN POSITIONING A VEHICLE
This type of risk may arise if the vehicle is not properly placed on the rubber supports (figure 3), or if the platforms are
not properly aligned with respect to the vehicle. One can avoid this by always lifting the vehicle using the car-jack
support points as advised by the vehicle manufacturer, and placing the vehicle as far as possible in the centre of the
platform.
CAUTION
Figure 3
While dismantling heavy parts (for example the motor or shafts), please note that the weight distribution ratios
change.
