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 41ºF (5ºC), 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.
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.
Steering of the loader
Steering of the loader is controlled with the steering wheel.
The steering system is hydraulically powered. A practical
way of steering is to steer with your left hand on the knob
of the steering wheel. This way your right hand is free to
operate other functions.
Pay attention to other machines and persons that are
moving in the area. Make sure that there are no persons
in the danger zone of the loader and the attachment. The
danger zone of the loader covers the reach area of the
loader boom, the turning area on the side and in the front
and rear of the loader. Always put down the load when
leaving the machine – the loader is not designed to stay
with the loader boom and load lifted. Learn how to operate
the loader in a safe place.
Always remember – safety rst.
Test all the functions of the loader
at an open and safe place. Make
sure that there are no persons in the
operating area of the machine and
the danger zone of the attachment.
Risk of tipping over - Keep load
close to ground. When driving,
always keep the loader boom as
low as possible. Risk of tipping
over increases considerably when
there is a heavy load on the loader
(a heavy attachment or a big load
in the bucket) and the boom is up
when driving.
Risk of tipping over - Keep load
close to ground. Never use a
high drive speed when turning. In
particular: when the loader boom
is up the stability of the machine is
much weaker when turning.
Risk of collision and crushing
Remember that, when turning, the
driver´s seat extends beyond the
turning radius of the wheels. Stay
inside the safety frame.
