Synchronous lift, function description

Synchronized lift means that lift and extension are activated at the

same time so that the lift is completely vertical. Synchronized lift is

activated by pressing in the pistol trigger on the control lever at the

same time as lift is activated.

Synchronized lift is controlled by the control system with signals

from Sensor boom angle and Sensor boom length.

The synchronized lift uses preset variables for the speed. The

hydraulic oil pumps must be adjusted correctly for the function

to work well.

For details on lift and extension, see Lift and lower, function descrip-

tion page 4 and Extension, function description page 10.
