•
Switch on the pump unit at lowest motor speed.
•
Let the oil pump around without pressure for a few minutes so that it warms up
a little.
•
You can accelerate warming up of the oil by moving a hydraulic cylinder to the
end stop.
At temperatures below 0° C make sure that your crane is being
operated with a hydraulic fluid which is suitable for such
temperatures.
The crane may only be operated by one person (operator) and from a control stand.
3.2-2 Supporting the vehicle properly
•
The crane must only be operated in properly supported condition.
•
Park the vehicle properly and apply the handbrake.
Spirit level
Every crane control stand has a bubble where you can read the inclination of the lorry.
With the bubble in the middle of the gauge the crane is in horizontal
position.
If the bubble is between the two circles the crane’s inclination is
between 0° and 5°.
After the crane has been mounted on the lorry the mounting company
has to adjust the spirit level.
Working in arm positions up 60°
Level the vehicle so that the inclination is maximum 3° in every direction.
When the vehicle stands in a maximum inclination of 3° then the
angle of 60° must not be exceeded with the load-bearing arm.Due to
the reduced guiding function of the hexagon profile of the
extendable arm this may cause the load-bearing arm swinging to
the side and the load being dropped.
