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 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.
