Usage Features
Cab Controls:
- Joystick:
- S, Classic, and Plus models: Controls boom lower/raise, loader/attachment rollback/dump, and gear up/down. A roller switch extends/retracts the boom, and a separate switch manages auxiliary hydraulic functions.
- Elite models: Feature a seat-mounted control and a different joystick design.
- Steering Wheel: Standard steering control.
- Foot Brake Pedal: For braking.
- Foot Throttle: For engine speed control.
- Machine Display: Provides operational information.
- Display Navigation Switch (enter/home, up/down arrow key): For menu navigation.
- Battery Isolator Switch: To disconnect the battery.
- Auxiliary Hydraulic Lock/Enable Switch: To control auxiliary hydraulics.
- "Road mode"/"Work mode" Switch: To select operating modes.
- De-clutch by Service Brake Enable Switch: Allows de-clutching with the service brake.
- Working Light Switches: For front, rear, and boom lights (optional).
- Rotating Beacon Switch: For the rotating beacon (optional).
- Roof Wiper Motor Switch: For the roof wiper.
- Steering Mode Selector: To choose between 2-wheel, 4-wheel, and crab steering.
- Radio: Optional.
- Transmission Mode Switch: To select transmission modes.
- Parking Brake Switch: Optional.
Transmission Modes:
- Plus models: Offer Manual and Semi-Auto shifting modes. Semi-Auto is suitable for road work.
- Elite models: Offer Manual, Semi-Auto (for short cycle jobs), and Full-Auto (for long cycle and road work) modes.
Shuttle Modes:
Three shuttle modes are available:
- Shuttling mode 1 (Comfort): Speed/ratio logic for smooth operation.
- Shuttling mode 2 (Silage / Heavy Duty): Optimized for demanding tasks.
- Shuttling mode 3 (Memory): Allows the operator to set preferred shuttle gears.
Changing modes involves navigating a "SETUP MENU" on the display using UP/DOWN buttons and selecting with the enter button.
Steering Mode Selection:
The telehandler offers three steering modes:
- 4-wheel steering (4WS): For maximum maneuverability in tight spaces (Left-hand side position A on the rotary switch).
- 2-wheel steering (2WS): For road driving (Central position B on the rotary switch). Always select this mode when driving on road.
- Crab steering: Allows the machine to move diagonally (Right-hand side position C on the rotary switch).
To select a mode, align the four wheels in the straight-ahead position, indicated by symbols (1) and (2) illuminating on the display.
Connecting Attachments:
- Ensure hydraulic locking pins are in the unlocked position.
- Lower the boom and position the machine parallel to the attachment.
- Rotate the headstock forward.
- Align with the attachment, lift the boom, and tilt back the headstock.
- Lock the locking pins via a button in the cab.
Automatic Lubrication System:
The telehandler can be equipped with two independent automatic lubrication systems:
- Main machine lubrication: A pump with an integrated control unit (1) greases various points on the machine. Lubrication duration can be time-dependent or based on pump motor revolutions.
- Boom kinematic lubrication: A separate pump (2) greases the boom's kinematic points. Lubrication is pressure-dependent, activating whenever the tilt cylinder starts working.
Rear Hitch:
Telehandlers can be equipped with a rear hitch with hydraulic and electric connections. UK models typically feature a pick-up hitch controlled from the cab. To release, a latch under the armrest must be released, then the third hydraulic function is used to lift/lower the hitch.
Load Cell Calibration:
A load cell calibration must be performed at least once per year to ensure safety and accuracy. The procedure involves:
- Key ON, push two specific switches within 5 seconds to enter calibration mode, then start the engine.
- With no load, fully raise the boom and retract the extension, then press enter.
- With a 2500-3000kg load, extend the boom parallel to the ground until the rear wheels lift, then press enter.
- Reduce total extension by 20% (from front wheels), then press enter.
- Reduce total extension by another 500mm, then press enter.
Maintenance Features
Easy and Quick Servicing:
- Full access engine bay: A large one-piece hood provides full access, with lower side panels also opening for enhanced access.
- Gas struts: Two gas struts reduce effort to open the hood and hold it open.
- Accessible daily checks: Engine oil, water coolant, air filter, and radiators are easy to check, fill, and clean. Radiators fold out for excellent cleaning access.
Less Maintenance, More Work:
- Extended service intervals: Class-leading 600-hour service intervals.
- Reduced downtime: Servicing is designed to be easier and less time-consuming, cutting downtime and costs.
Daily Fluid Checks (before starting):
- Engine oil
- Hydraulic reservoir oil
- Transmission oil
- Fuel
- Cooling liquid
- Brake oil
