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.

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)

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

While dismantling heavy parts (for example the motor or shafts), please note that the weight distribution ratios
change.
