Solenoid valves 3 (EV11) and 4 (EV12)
These bypass solenoid valves allow the hydraulic block to be put into pressure in the column;
Solenoid valve 3 powers the extension and retraction of the telescopic boom;
Solenoid valve 4 powers all the other movements of the aerial part;
Under normal use conditions of the machine, if they are not energised they send the oil to be
drained;
These valves must have the part that can be manually operated completely unscrewed or fully
rotated anti-clockwise.
Solenoid valves 5 (EV1) and 6 (EV2)
These solenoid valves control translation of the machine;
If the solenoid valves 1 (EV9) and 2 (EV10) are manually bypassed, the machine can be moved by
simply pressing or pulling the manually operated part of the valve (with the engine running);
Pressing valve 5 controls translation of the left track in the direction indicated by the arrow;
If the valve is pulled, the movement is in the opposite direction;
If valve 6 is pressed, the right-hand track is moved in the direction indicated by the arrow;
If the valve is pulled, the movement is in the opposite direction.
Attention : These manoeuvres may only be performed by technicians authorised by Almac.
Attention : Reset the valves 1-2-3-4 in the correct position at the end of any operation that involves
their handling.
Attention : Danger of tipping over of the platform or crushing of the operators.
