19 - EXTERIOR DRAIN-BACK
Enables connection of a hydraulic attachment for which drain-back is required.
20 - ATTACHMENT HYDRAULIC CONTROL FORCED OPERATION
t
IMPORTANT
t
This OPTION must only be used with an attachment requiring continuous hydraulic movement, such as a brush, feeder
bucket, mixer, spray etc. It is strictly forbidden for use in handling operations and all other applications (winch, crane
jib, crane jib with winch, hook, etc.).
Never leave the driver's cab without resetting the potentiometer C to 0%.
Before starting the lift truck, make sure that this potentiometer is at 0%.
CONTINUOUS HYDRAULIC MOVEMENT OF THE ATTACHMENT
- Check that potentiometer C is set to 0 %.
- Switch button A to the front or the back (depending on the type of attachment),
press button B and release button A. The red indicator 1 flashes to indicate that
it is in operation.
- Set the required flow rate using potentiometer C.
- To stop continuous hydraulic movement of the attachment, move switch A forwards
or backwards or press button B. Indicator 1 goes out.
- Set potentiometer C to 0 %.
NOTE: If the operator leaves the driver's cab, the continuous hydraulic movement
will automatically stop and must be restarted.
21 - BOOM SUSPENSION
MT733...-MT933...
The boom suspension dampens shaking of the lift truck on rough ground (e.g. handling
straw in a field).
t
IMPORTANT
t
The boom suspension remains active up to carriage hinge pin lift height of 3.00m relative to the ground, with
the boom retracted.
When you exceed this height or when you perform another hydraulic movement (tilt, telescoping, attachment),
the boom suspension is momentarily deactivated and the lamp on switch 1 goes out.
OPERATION
- Set the forks or attachment down on the ground and raise the front wheels by
a few centimetres only.
- Press switch1 in position A, the indicator lamp comes on indicating that boom
suspension is activated.
- Press switch1 in position B, the indicator lamp goes out indicating that the boom suspension is deactivated.
- When the engine is off, boom suspension is automatically deactivated.
