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 auxiliary hydraulics pump to
run at idle. 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.
WARNING
In case braking power of
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.

Battery system in cold environment
The battery pack is less capable to supply energy in
cold environment. This sets a limit to the minimum
operating temperature where the loader can be
practically used. Operating in cold conditions will
decrease battery performance and cold, stiff
hydraulic oil will waste more energy.
To reach maximum battery capacity in freezing
conditions, keep the loader stored in warm shelter.
Battery will then remain relatively warm during use
and will be able to output as much energy as
possible.
Braking performance in cold environment
The braking performance of the loader will depend
on the ability of the lithium-ion battery to receive the
energy from braking. If the ambient temperature is
below +5 °C, the braking performance can be
significantly decreased. In case the control systems
of the loader observe insufficient braking
performance, the parking brake will be applied
automatically. Allow the loader to warm up, and
connect the charger to ensure sufficient temperature
of the battery.
Battery cooling and heating systems
The performance of the battery, service life, and time
needed for recharge are influenced by ambient
temperature. The lithium-ion battery is equipped with
a Battery Management System (BMS) that controls
the functions of the battery during use and charging.
After heavy load or high ambient temperature, the
charge process will take longer time, as the Battery
management system limits the charging current
automatically.
The temperature of the battery is controlled with
forced air cooling and heating units inside the battery
pack. These functions are controlled by the BMS.
The Battery Management System activates cooling
and heating if the ambient temperature deviates from
the optimum operation window of the battery.
However, this will use battery power and thus
reduces its state of charge. If the battery is empty
and a charger is not connected, heating or cooling of
the battery is not possible, leading to potential
damage to the battery. See page 74 for instructions
regarding storage.
