Operation
3.5.5 Lowering the telescopic unit with the engine switched off
☞
Proceed as follows:
• Make sure that no-one is dangerously close to the telescopic unit
• Push control lever 21 forward (C), until the telescopic unit is fully lowered
• Return control lever 21 to neutral
3.5.6 Relieving pressure the quick couplers on the telescopic unit
NOTE:
The hydraulic system of the 3rd control circuit/attachment is still pressurized even
when the engine is not running! The hydraulic quick couplers can be released,
however they cannot be re-attached because the pressure in the hydraulic lines is
too high. Therefore:
☞
Depressurize sections of the system and hydraulic lines which are to be
opened before starting setup or repair work, e.g. fitting/removing an attach-
ment!
☞
Depressurize as follows:
• Apply parking brake 16/25 – see Parking brake [25] on page 3-10
• Switch off the engine
• Move lever 22 forward and backward several times
