17 - HYDRAULIC CONTROLS AND TRANSMISSION CUT-OFF
Do not attempt to alter the hydraulic system pressure by interfering with the pressure regulating valve. In
the event of suspected malfunction, contact your dealer. ANY ALTERATION MAY RENDER THE WARRANTY
NULL AND VOID.
Use the hydraulic controls carefully without jerking, to avoid accidents caused by shaking the lift truck.
NOTE: When driving on the road, it is highly recommended (mandatory in Germany) that you
cut-off all the hydraulic movements (see: 2 - DESCRIPTION 7 - SWITCHES).
NOTE: If necessary use the steering to reset the hydraulic control steering accumulator.
A - Lifting and tilting control lever.
B - Telescoping control button.
C - Attachment control button.
LIFTING THE LOAD

- The lever A forwards when lowering.
TILT OF CARRIAGE
- The lever A to the left for reverse tilt.
- The lever A to the right for forward tilt.
TELESCOPING

ATTACHMENT

DECOMPRESSION OF OPTIONAL CIRCUIT
This operation must be carried out each time a lift truck supplementary accessory is to be
connected or disconnected.
1) Switch the combustion engine off and turn ignition key to position “I”.
2) Rotate roller “C” forwards and backwards, turn the roller for 3 seconds for each position
(pushbutton D pressed and red indicator light On).
When the operation is complete, the optional is depressurized; it will therefore be easier to
connect/disconnect the quick-release couplings on the top of the boom.
N. B. The operations must be carried out immediately after the combustion engine is switched
off, and not for more than 3 seconds for each command.
