Allow the loader to warm up properly
Hydraulic oil temperature has an effect on the
hydrostatic drive system of the loader. When the
ambient temperature is below 5 ºC, make sure the
general response to drive pedals is normal. If the
drive feels sluggish, allow the hydraulic system to
warm up by letting the loader to run at idle until the
drive system works normally. Drive carefully until the
loader has reached its normal operating temperature.
WARNING
Risk of decreased braking
power - Make sure hydraulic oil
is not overheated. When
hydraulic oil gets hot, driving
characteristics of the drive system
change. When the oil is hot and
the hydraulic oil cooler has
switched on, stopping distance of
the machine can be longer than
when the machine is cold. If the
loader is used constantly in high
ambient temperatures, hydraulic oil
type and viscosity must be suitable
for these conditions. Contact Avant
service.
In case the braking power of the
hydrostatic drive system has
decreased, engage the parking
brake. The rear wheels may lock
immediately. Parking brake acts as
an emergency brake, and will also
engage in case of loss of oil
pressure. Parking brake is
intended to keep the loader
stationary and not for repeated
braking. Engage while loader
moves only when necessary.
.
Engine block heater (option)
The loader can be equipped, as an option, with an
engine block heater. The block heater warms up the
engine coolant to help starting of the loader in cold
conditions. Using the block heater also helps to
reduce cold start emissions.
The engine block heater must be connected to a
grounded mains socket that is also protected with a
residual current switch. A grounded socket does not
prevent the risk of electric shock when a live cable is
left on e.g. wet ground. Always disconnect both ends
of the cable. Use only correct type of cable that is
intended to be used with the block heater model that
is installed on the loader.
The socket for the block heater (if installed) is
located on the left side of the loader:
WARNING
Risk of fire and electric shock -
Check the voltage rating of the
block heater. Always use
approved type of cable. Check
that the design voltage of the block
heater matches the mains voltage
of your area. The standard block
heater is intended to be connected
220-240 V AC mains socket.
Always plug the block heater to a
grounded socket that is equipped
with a residual current switch. Use
only original type of cable to
connect the block heater. Protect
electric sockets from rain.
