Figure: 151059-1
WARNING! If the Brake fluid low level indicator
light (fig. 151059-2) stays on even after adding oil,
contact a Dieci authorized service center to solve
the problem.
A slight lowering of the level is due to normal wear of
the brake discs.
Do not press the brake pedal until the topping up is
completed. Make sure the tank is closed before acting
on the pedal.
10.14 - Wheel maintenance
10.14.1 - Epicycloidal reduction gear
oil: Check and replacement
Figure: 150577-1
The oil cap of the epicycloidal reduction gear is
located on the wheel hub (fig. 150577-1):
When checking the oil level it is necessary to:
• Prepare the vehicle in the maintenance position.
• Turn the wheel for the oil cap to be in the
horizontal position (9 o'clock).
• Place a container to collect the oil.
• Remove the cap and verify that the oil seeps from
the hole.
• If necessary, top-up through the same hole.
• Close the cap and tighten it securely.
When replacing the oil it is necessary to:
• Prepare the vehicle in the maintenance position.
• Turn the wheel for the oil cap to be in the lowest
possible position (6 o'clock).
• Place a container to collect the oil.
• Remove the cap and let the oil drain completely.
• Turn the wheel and bring the cap to the
horizontal position (9 o'clock).
• Fill through the same cap with new oil until it
seeps through.
• Close the cap and tighten it securely.
10.14.2 - Wheel nuts tightening
NOTE
Tighten the nuts at the intervals required in the
maintenance table.
Use the corresponding table to know the correct
tightening torque.
Always tighten the nuts in opposing position, not
consecutively.
After installing the wheel, tighten the nuts between
the wheel and the axles. Then check the nut torque
every day until the torque is stabilized.
The number of axle columns must match the number
of nuts tightened. Then all the nuts on each wheel
must be installed otherwise the vehicle can not
operate.
In case of wheel replacement the vehicle or the raised
side can be placed on the ground only with wheels
installed and properly tightened.
The nuts tightening must be made first with the
vehicle, or part of it, raised from the ground then with
vehicle resting on the ground.
Only use
DIECI
original nuts for tightening the
wheels. If you lose even one nut contact the
DIECI
service center.
