DRIVING INSTRUCTIONS

STEERING WHEEL HANDLING
For smooth operation, do not turn the steering wheel
suddenly or hit the stop with force at the end of the
turn. Sharp turns of the steering wheel will produce
jerking motion and possibly over-correction on the
next move of the steering wheel.
Adjust the amplitude of the steering movement with
the speed of the vehicle. The faster the speed of the
vehicle, the slower the steering inputs should be,
except for an emergency situation.
At slow speed, turning the wheel slightly will decrease
track speed on one side and increase it on the other
side. Turning the wheel further will stop one track and
keep the other one running. Turning the wheel to the
stop will produce counter-rotation: turning one track in
one direction while turning the other track in the oppo-
site direction.
At full speed, both tracks may already be at maximum
speed so the vehicle is likely to slow down slightly
when turning.
AUTO-BRAKE
If the vehicle is immobilized for a few seconds, the
auto-brake function is activated and brakes are
applied automatically. This is to prevent the vehicle
from creeping backwards on a slope. As soon as the
speed pedal is pressed again, the auto-brake function
is deactivated and brakes are released.
The icon shown above appears on the LCD display
whenever the auto-brake function is activated.
DANGER
Accident hazard
The operator must be aware of the vehicle con-
figuration and normal/inverted drive setting at
all times. In the inverted configuration, the
transmission lever and the steering wheel are
inverted.
Not taking into account the vehicle configura-
tion may result in severe injury or death.
OIL TEMPERATURE AND DRIVE SYSTEM
Low oil temperature
Low hydraulic oil temperature will trigger a warm up
sequence of the drive system.
The icons shown above appear on the LCD display whenever the oil
temperature reaches critical low level.
When the oil temperature is colder than +5 °C
(+41 °F), there is a warm up curve of the drive system
that limits the diesel engine maximum speed to
1400 rpm. The snowflake icon appears on the display
in that oil temperature range.
When a low oil temperature indication occurs, leave
the engine running at idle speed until the oil returns to
normal operating temperature or work while applying
only a light load to the engine.
When the oil temperature increases above +5 °C
(+41 °F), the buzzer will sound and the snow icon will
flash.
The accelerator pedal must be released before
the vehicle can regain its full speed capacity
(2100 rpm max.).
High oil temperature
High hydraulic oil temperature could cause permanent
damage to the hydraulic circuit and to several compo-
nents. To prevent this, heat sensors and the vehicle
microprocessor will trigger a cooling sequence to
lower the oil temperature.
High hydraulic oil temperature can cause oil degrada-
tion and, eventually, bring premature failure of the
components operating with that fluid.
As the oil temperature increases, its viscosity
decreases. Therefore, a hydraulic system is operating
too hot when it reaches the temperature at which oil
viscosity falls below that required for adequate lubrica-
tion.
Hot oil can destroy hydraulic components, seals,
hoses and the oil itself when high-temperature opera-
tion is allowed. Avoid this situations as much as possi-
ble.
