9.4.2 Steering
Check (to perform every 150h)
The steering must always be precise and
free to rotate smoothly. Check that the
ring and the pinion coupling chain has
no excessive clearance and is not noisy.
Maintenance (to perform every 600h)
Periodically grease the ring and pinion
coupling chain. If the chain is too loose,
adjust the chain tension as described in
the ”Settings” paragraph.
9.4.2-137
9.4.3 Front Wheel
Check (to perform every 150h)
The wheel must be free to rotate
smoothly without friction. The wheel
surface, must always be in good condi-
tion.
Maintenance (to perform every 600h)
Periodically check the wheel bearings
status. Periodically grease the wheel
bearings.
9.4.4 Traction motor
Check (to perform every 150h)
Lift one of the two rear wheels and
activate the traction, the current ab-
sorption measured on the motor has to
be less than 3 Amps.
ATTENTION: At the start and when
accelerating the absorption current of
the motor is much higher.
The motor should rotate evenly and
smoothly and doesn’t have to produce
unusual noises. The motor contacts
have to be clean, they have not to show
signs of wear or heating in general.
The motor wires insulation has to be
intact in all its parts and does not show
signs of cracks. The single cable have to
be flexible.
The carbon brushes must be 4-6 mm
long and they have not to be abnormally
worn out.
Electrobrake (see fig. 9.4.4-138):
With raised lever (electrobrake engaged)
the machine is always braked unless it
is turned on with the operator on board
and with traction pedal pressed.
With lowered lever (electrobrake NOT
engaged) the machine is always free to
move.
ATTENTION: If the electric brake is NOT
engaged, the function wheel machine is
inhibited for safety reasons (there will
be an alarm on the display).
Differential: Lifting the machine to
make the rear wheels neutral, by spin-
ning a wheel (in any sense) the other
should turn in the opposite direction.
