Every time the crane is in use, the vehicle must be stabilized and secured so that it
cannot roll away.
Make sure the ground is capable of bearing the load. If necessary, earth pressure
can be reduced by the use of suitable load spreaders.
Only use the ladder and grip handles to get on and off the seat.
Damage must be repaired or reported immediately. Only resume work with the crane
when the damage has been repaired.
Only lift loads when the vehicle has been adequately stabilized.
No person may enter the working or rotating range.
Seal off the working area.
