8.2.9 Tightening torques for rotating assembly
WARNING
Danger through incorrect tightening torques!
If screws and bolts are tightened with incorrect tightening torque, components may
tear free and cause injury and damage.
– Never exceed the maximum permissible tightening torque.
– Regularly double-check the tightening torques.
– Always observe the applicable guidelines and design criteria for threaded con-
nections.
The table lists the tightening torques required for reaching the maximum permiss-
ible tightening of the rotating assembly’s bolts.
Bolt dimensions Bolt grade Tightening torque

8.2.10 Winter operation
In order to prevent faults during operation of the aerial lift platform in wintry
weather, the necessary measures include the following preventive measures:
n
Prevent build-up of water residue.
n The water drain holes have to be free.
n
Do not use steam jets on the machine.
n Keep the ladder and the floor of the working basket free from snow and ice.
n Sliding blocks must not become frozen on components.
n
Make sure that chains and ropes which are used to retract and extend the pro-
file are kept free from ice.
n
Check the sensor equipment to make sure it is clean.
n All the limit switches and proximity switches must be free from snow and ice.
Use heat or lubricant with de-icing or water-resistant / anti-corrosive properties
to restore freedom of movement.
n In extreme cold, the hydraulic system needs to be heated up. This can be
achieved by keeping the drive unit running or by moving the crawler tracks, out-
riggers or platforms slightly.
n Observe the drive motor’s operating instructions (e.g. running the engine to op-
erating temperature, anti-freeze, battery charge etc.).
