Control Center
The all-new, deluxe operating space was engineered with 3-D modelling to optimize your ultimate control centre. The wide, tinted and laminated front windshield has no framing cutting through to ensure excellent visibility.
Adjustable steering column
The Air Conditioning and Heating System
The operator can easily control the temperature and air flow. The defroster on the front windshield and rear window makes it convenient for winter working usage.

FNR Switch on Joystick Control Lever
A forward/neutral/reverse travel switch can be installed on top of it for operators convenience. [. . . ] For each gear change, the control unit performs a monitoring function to ensure that the specified shift curve is adhered to, and readjusts the shift pressure applied to the clutches accordingly. This result in smooth gearshifts under load without traction interrupts. It also prevents standstills, sudden load changes or torque peaks during operations such as steep hill driving with full load. In addition, there is the option for the driver to make manual gearshifts.

An ideal arrangement of components ensures quick and convenient maintenance. Highly accessible engine compartment assures fast and efficient repairs when necessary.
Hydraulic tank
The hydraulic tank is located behind the cab to facilitate the accessibility of hydraulic hoses and pipes.
Oil sight gauge
A sight gauge is installed on the side of the hydraulic tank for convenient ground level check out.
Transmission oil port
The transmission oil change port is openly accessible. It comes with an anti-vandalism lock for machine protection.
Central electric controllers & Fuse Box
Electric controllers and a concentrated fuse box are centralized to improve serviceability.
Cabin Air Fresh Filter
The internal pressure is maintained slightly higher than the outside to exclude dust from entering in and reduce noise levels to the cabin.
Coolant Sight Gauge
A coolant sight gauge is installed on the top of the radiator for convenient checks of coolant level.
Easy Access to All Engine Components
Here you find the engine oil check, main and pre-filters (fuel, oil, coolant). The large engine-sidepanels permit easy and safe access for inspections. The filters can be screwed on and off for quick replacements.
Up-to-date hydraulic remote cooling fan
Minimum fuel consumption and low noise is realized by using a hydraulic cooling fan sensing coolant temperature, intake air temperature, transmission oil temperature and hydraulic oil temperature. Reversible cooling fan is installed.
