Panther T14R - Operation and maintenance manual
DRIVING INSTRUCTIONS
95/178
Oil in the tank
Maximum diesel engine speed, 2100 rpm, is allowed
with hydraulic oil temperature up to +76 °C (+169 °F).
At higher hyd. oil temperature, allowed maximum
engine speed will be gradually reduced (down to
1700 rpm) as the oil temperature increases.
If the oil temperature rises at +85 °C (+185 °F) or
more, the drive system will be limited to 50 % of maxi-
mum speed (and the engine speed limited to
1700 rpm) until the hyd. oil temperature goes down to
a safe level.
NOTE : Operator must stop the vehicle to prevent
damage if alarm sounds. Inspect cooling compo-
nents at once. When the high oil temp icon and the
yellow triangle flashes, release the accelerator
pedal completely to enable the vehicle to regain
full speed capability.
This icon appears on the LCD display whenever the oil temperature
reaches a critical levels.
Oil in the planetary gearboxes
High oil temperature in the planetary gearboxes will
result in a drive system power adjustment on two lev-
els:
» First level:
» Second level:
The icons shown above appear on the LCD display whenever the oil
temperature reaches a critical level in the planetary gearboxes.
» Yellow temperature icon: max speed reduced by 25%.
» Red temperature icon: max speed reduced by 50%.
NOTE :
Operator must stop the vehicle to prevent damage
if alarm sounds. Inspect :
» Hyd oil level and quality in the planetaries;
» Planetaries housing and components.
Lowering the oil temperature in the tank or in
the planetary gearboxes
When a high oil temperature indication occurs, the
power adjustment will slow down the vehicle to lower
the oil temperature.
Regaining speed capability after a first level
alarm (flashing yellow planetary icon)
Once the oil temperature drops below the critical level
(the yellow planetary icon will flash), release the accel-
erator pedal completely to enable the vehicle to regain
full speed capability.
Regaining speed capability after a second
level alarm (flashing red planetary icon)
Once the oil temperature drops below the critical level
(the red planetary icon will flash), release the accelera-
tor pedal completely to enable the vehicle to regain full
speed capability.
Regaining speed capability after a hyd oil
temp alarm (red oil icon)
It is recommended to stop the vehicle and perform a
quick check to try to spot the problem. Ensure the oil
cooler is clean and air circulation is unobstructed.
Maximum speed capability returns automatically when
the oil temperature drops below the critical level
(check the oil temperature gauge).
NOTE : Perform the clearing fault procedure to erase
the fault.
