500 SeriesSafety instructions
Whenever you handle heavy loads or heavy attachments:
Overload - Risk of overturning.
The high lift capacity of the loader makes
it possible to exceed the stability of
the loader when handling loads. Read
CAUTION
WARNING
WARNING
the instructions regarding maximum
lift capacity and load handling in this
Operator’s Manual. Following the
instructions reduces the risk of tipping
the machine over its front axle, but the
operator must be aware of the limits of
the machine and follow safe working
practises to avoid overturning of the
machine.
Articulated frame - Risk of
overturning. Turning articulated frame
can lead to overturning of the loader
on inclined terrain or when driving at
high speed. Never turn frame towards
the slope while operating on inclined
ground. Always drive slowly when
carrying load or when turning with the
machine.
Sudden movements can tip the
machine over - Risk of overturning.
Movements, such as stopping, turning,
or lowering the boom abruptly, can
cause loss of stability. Always drive
slowly and operate the controls of the
loader very carefully, especially when
handling heavy loads.
In case the loader tips over :
Avoid tipping over of the loader with careful operation and
the instructions given throughout this manual. However, it
is important to know what to do in case the machine tips
over.
Risk of being crushed by the ROPS
structure in case the laoder tips over

off the engine of the loader immediately.
Running the engine and pumps of an
overturned loader will damage them
quickly and will spill hydraulic oil and
fuel. As soon as possible, lift the loader
back on its wheels to prevent spilling of
fuel and oils. The loader can in many
cases be lifted back on its wheels
by having a few persons to lift it from
the ROPS frame. Engine oil can leak
inside the engine, causing major engine
damage if the engine is attempted to
be restarted after the loader has been
overturned. Contact service before you
attempt to restart the engine.

monoxide (CO), a poison gas you
cannot see or smell. Using a loader
in enclosed space or poorly ventilated
DANGER
Never operate the loader indoors or in partly enclosed
areas unless you’ve made sure there is special ventilation
system installed. Loaders with a combustion engine produce,
among other pollutants, carbon dioxide (CO2) and can also
emit carbon monoxide (CO) under some conditions that can
concentrate quickly to a dangerous level. Never leave the
engine running in garages or sheds. Operate the loader
only outdoors and far from windows, doors, and vents.
Elevated level of carbon dioxide or carbon monoxide
in breathing air can not be noticed without dedicated
measuring equipment. Signs of carbon monoxide poisoning
include nausea, headache, dizziness, drowsiness, and lack
of consciousness.
Get fresh air if anyone shows signs of carbon monoxide
poisoning and see a physician.
areas will kill you in minutes.
Diesel exhaust also contains other chemicals that are
harmful. Prolonged exposure to exhaust fumes should be
avoided. Ventilate indoor spaces well e.g. after starting a
loader. The odor or colour of diesel exhaust does not tell
if there are dangerous levels of carbon dioxide or carbon
monoxide in the breathing air.

Tipping load
500 Series
Tipping load
Tipping load
Tipping load is the load at which the rear tires lose contact
with the ground (tipping forward). Tipping load is inuenced
by several factors:
• The total load on the loader boom (attachment weight
and load combined)
• The distance of the load from the front tires
• Straight or articulated position of the loader frame
• Levelness of the ground
• Installed counterweights
• Driver presence
• Movements of the loader and the load
Overload will cause the loader to tip
forward. Always pay attention to safe
operating conditions whenever lifting
loads or handling heavy attachments.
CAUTION
Load diagram
You can evaluate the load handling capability of the
loader with the load diagram, shown below, and the Rated
operating capacity shown on the next page and on the
label on the loader.The load handling capability depends
on the distance between the centre of gravity of the load
and the front axle of the loader.The diagram represents
the forward stability only, it does not refer to maximum
available lift force.
The load diagram below shows the tipping loads on a level
surface:
a) Tipping load with the loader frame in straight position.
b) Tipping load with the loader frame in maximum
articulation.
• ROC (Rate operating capacity), dened as 60 % of
tipping load for pallet forks.

The lifting capacity and the stability of the loader are at the
best, when:
• the loader frame is kept straight
• the centre of gravity of the load is as close to the loader
as possible
• counterweights are tted to the loader
• swinging of the load is prevented and all controls are
used in a calm and careful manner
Example: If the centre of gravity of the load is 750 mm in
in front of the front axle (400 mm from the pallet forks at
ground level), the tipping load is about 700 kg (523) and
820 kg (528/530) with a driver weighting 75 kg and with the
articulated frame turned to max articulation.
If you leave the loader, tipping and max. loads
are reduced respectively. The indicated load
is the maximum load that can be loaded on
pallet forks and the machine will not tip over,
WARNING
i.e. the weight of the standard pallet fork
attachment (90 kg) is taken into account.

Rated operating capacity
To determine how much the loader can handle safely, a
table of the tipping load and a calculated Rated Operating
Capacity (ROC) is shown in the adjacent label.
A rated Operating capacity label is located near the driver’s
seat and can be read while you sit on the driver’s seat.
Rated operating capacity depends on type of use of the
loader:
• In bucket and general application the rated operating
capacity is 50% of tipping load
• In pallet fork application the rated operating capacity is
60% of tipping load
The information shown in the table is the worst case
minimum load, with the conditions listed below. Actual lifting
capacity could be signicantly higher, or it may be lower,
depending on terrain conditions, available lifting force, and
load distribution. Adding or removing counterweights will
affect the indicated ROC.

to damaged electric wires, short-circuit, and overheat of
electric components.
Risk of re - Always switch off main
current when the loader is not used.
Turn the battery disconnect switch to
position OFF whenever leaving the
WARNING
loader unattended or before servicing
the machine. If left on, there is a risk
of sparks and short-circuit during
maintenance and if any electric
insulator is faulty.
Installing of service support
The red service support of the
boom lift cylinder is located at
the tip of the boom, behind the
attachment coupling plate.
Make sure that the boom
stays up during maintenance
operations by attaching the
service support on the lift
cylinder piston rod. Secure the
service support by locking it
on the piston rod with the long
screw that is on the support.
Risk of crushing - Always secure
the boom service support on the
boom lift cylinder before going
under the boom or any attachment.
WARNING
Always secure the loader boom with

CAUTION
CAUTION
0-9 km/h 0-19 km/h
100% 50%
100% 25%
Risk of abrupt movement - Do not
change the drive speed range while
driving with a higher speed. Always
stop the machine rst or slow down the
speed before switching on higher or
lower speed.
Risk of loss of control - Be careful
when driving at higher speed range.
Abrupt control movements can cause
the loader to roll over. Do not turn
the steering wheel quickly when you
drive at high travel speed. Drive slowly
whenever carrying loads, driving on
inclined or rough terrain, or on slippery
surfaces. Always reduce speed before
sharp turns.
Drive release valve
The switch with the text LOCK
controls a valve, which is used to
divert the oil ow between left and
right side hydraulic motors. This
affects the pulling force.
LOCK OFF: In this mode, the
hydraulic oil ows in series from motor to motor. The
wheels will roll more freely and the loader leaves less tire
marks on soft surfaces.
LOCK ON: In this mode the hydraulic oil ows in parallel
between the hydraulic motors in each side, similar to a
differential lock in operation. This improves the towing
capability of the loader.
Parking brake switch
Avant 523/528/530 is equipped with a hydraulic parking
brake. The parking brake is operated with the switch on
the control panel right (see page 26). On cab LX/DLX the
switch is located in the panel up right.
• A red indicator on the switch lights up when
parking brake is engaged.
• The green backlight under the “P” is lit all
the time.
The parking brake engages automatically when the engine
is stopped. The brake can be released only when the
engine is running and there is hydraulic pressure in the
system.
Risk of sudden stop - Do not engage
the parking brake when the machine
is moving unless in emergency.
Using the brake while moving may
CAUTION
NOTICE
cause the locking of wheels and
sudden stopping of the machine.
If the parking brake is engaged
repeatedly when the machine is moving
the brake plates in the drive motors
will get worn quickly. Always stop the
loader before engaging the brake.
Anti slip valve (option)
If the loader is equipped with the
optional anti-slip valve, there is an
additional switch on the back of the
joystick. The valve equalizes the
oil ow between the left and right
side hydraulic motors, improving
traction on slippery and uneven
surfaces. The anti slip valve is
engaged by pressing continuously
on the switch on the joystick. As soon as the switch is
released, anti slip valve is released. The function of the
anti slip valve depends also on the position of the drive
release switch:
X-lock OFF: The anti slip valve equalizes the oil ow
between the left and right hydraulic motors, but some
oil will pass between the left and right side of the loader
through the open X-lock valve.
X-lock ON: The anti slip valve equalizes oil ow between
the left and right hydraulic motors - all four wheels spin
equally and provide the best possible traction.

500 SeriesOperating instructions
Loader control
The loader boom and bucket are controlled with the multifunction lever sideways (tilt) and back & forward (boom up
& down).
• Pull backward to lift the boom
• Push forward to lower the boom
• Push left to raise the tip of the
bucket (lling)
• Push right to lower the tip of
the bucket (emptying)
For details about how to operate the loader with different
attachments, refer to the Operator’s manual of each
attachment. For example, instructions regarding the use
of a bucket are shown in the operator’s manual of bucket.
Telescopic boom
The telescopic boom makes many
tasks easier, also those that do
not involve lifting. You can, for
example, push material further with
a bucket, reach into difcult areas,
and improve visibility to the work
area with some attachments.
Telescopic boom is operated with
the control lever on the control
panel (see page 25). Turn the
control lever of the telescopic boom
to the right to extend the boom, and
turn to the left to retract it.
Length of the telescope is 600 mm
and additional lifting height is 485 mm.
Risk of tipping over - Extended
boom can cause the loader to
tip over. Use telescopic boom with
caution. The stability of the loader
WARNING
depends on the distance of the load
from the front of the loader. When you
extend the boom, you increase the
effect of the weight and reduce safe
handling capacity. See pages 22 and
50 for further instructions about tipping
load and safe material handling.
Boom floating (option)
The oating system releases the lift cylinder to allow it to
move upwards. This will allow the attachment to follow the
contours of the terrain, making grading and leveling work
easier. The boom can move upwards from the position
where the boom oating is switched on.
1. Lower the boom down. With some attachments and work
tasks, it may be useful to press down the attachment
before you switch on the oating.
2. Switch on the oating with the
switch on the dashboard, see

NOTICE
WARNING
If the loader is also equipped with
the Smooth drive option, the oating
function will be activated whenever the
smooth drive is activated.
The oating releases the boom to
move up from the position from where
it is switched on. Lower the attachment
rmly on the ground before you switch
on the oating. In some tasks, it may
be useful to press the attachment
down so, that the front wheels of the
loader lift off from the ground.
Some attachment have a oating
linkage built in the attachment coupling,
making use of the oating on the loader
unnecessary. Refer to the operator’s
manual of the attachment for more
information.
Risk of lowering of the boom when
switching on boom oating - Lower
boom to close to the ground before
switching on boom oating. Switch
on the boom oating only when
stationary and when the load is close
to the ground. Boom can move down
when you switch on the boom oating,
if the loader is equipped with the

500 Series Operating instructions
Self leveling boom (option)
The boom self leveling system keeps
the position of the attachment the same
in relation to the ground, regardless of
the position of the boom.
Self leveling is hydraulic: there is a
leveling cylinder on the left side of the
boom which follows the movements of
the bucket tilt cylinder and keeps the
attachment level.
NOTE: Self leveling is disabled when the boom oating is
switched on.
Smooth drive (option)
Avant 523/528/530 can be equipped,
as an option, with the smooth drive
which is a shock absorber system for
the boom. When driving at high speed
with a heavy load or heavy attachment,
the boom starts to move up and
down, making driving unpleasant. The
smooth drive consists of a hydraulic
pressure accumulator, which absorbs
and eliminates boom movements and
makes driving considerably smoother and more stable.
Smooth drive is switched on with the boom oating switch,
and is active whenever boom oating is also activated.
NOTE: The loader must also be equipped with both boom
self leveling and boom oating options.
Risk of lowering of the boom when
switching on boom suspension Lower boom before switching on.

Drive control
WARNING
500 Series Operating instructions
Avoid collisions - Practice the use of the loader at a safe area. Familiarize yourself
with the driving of the machine on low speed and on a at, even and open place where
unintended movements will not cause collisions or danger to yourself or others. When
you have learned how to drive on low speed, increase speed gradually and learn how
to drive with higher drive speeds. Make sure that there are no persons in the operating
area of the machine.
Principle of operation
AVANT 500 serie is equipped with a hydrostatic drive system. In the drive circuit there
is a variable displacement hydraulic pump that is proportionally controlled with the two
drive pedals.
Driving of the machine is controlled with the drive pedals and hand throttle.
• Select the engine speed with the hand throttle lever on the control panel
• Control desired driving direction and speed with the drive pedals
• To get the maximum pushing power push the pedals lightly – for higher travel speed
push the pedal harder
Risk of loss of control and rolling over of the loader - Reduce
speed before sharp turns and when driving on uneven terrain.
Abrupt control movements can tip the loader over. Do not turn
the steering wheel quickly when you drive at high travel speed. Drive
WARNING
Drive control
• Driving forward: press gently on the right drive pedal until the machine starts to move
slowly.
• To drive backward: press gently on the left drive pedal.
• When you wish to stop gently release the pedal by lifting of your foot, and the machine
will slow and stop.
The basic rule is: use lower revs for lighter work and higher revs for hard work or for
high travel speed.
The hand throttle can be used to control engine speed also while driving.
NOTICE
slowly whenever carrying loads, driving on inclined or rough terrain,
or on slippery surfaces. Always reduce speed before sharp turns.
The hand throttle also has an effect on the operation speed of a
hydraulically driven attachment: the more throttle the faster the
attachment operates. Make sure not to exceed max. allowed oil ow
of the attachment.
When you want to have a high pulling force:
1. Choose low speed range (530)
2. Use high engine RPM
3. Press the drive pedal only lightly to select a relatively slow drive speed. This way the
full output of the hydraulic system and the engine can be taken out. If the engine is
overloaded while pushing, the pedal shouldn’t be pressed further, but instead use
higher engine RPM and push pedal only a little.
37
500 SeriesOperating instructions
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
WARNING
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.

Safety
WARNING
Familiarise yourself with the special
drive features and space needs of this
articulated loader, equipped with cab,
on a at, even and open place.
Remember that, when turning, the cab
extends beyond the turning radius of
the wheels. This should be taken into
consideration especially when driving
in conned spaces, in order that the
rear of the cab will not get damaged.
If necessary, the windscreen can be
broken with the emergency hammer
in the cab. This way it is possible to
get out of the cab in an emergency
situation.
Do not drive with the cab door open,
nor turn the steering wheel when the
cab door is open. The door may break
upon contact with wheels.
Air ow temperature can be adjusted with the rotary switch
of the heater, located at seat base. Air ow can be directed
with the nozzles on the front panel and in the footwell.
For faster heating, the cab is equipped with an air
recirculation system. A ventilation hatch is located below
the seat in the footwell. When the hatch is opened the
heating system pulls air from the cab and circulates it
through the nozzles back in the cab. This way the cab
warms up quicker in cold weather. The system can also be
used for cooling.
NOTICE
A replaceable cab air lter can be changed from outside
the cab, under the door on the left side (see picture above).
The cartridge (part no. 65118) should be changed more
often in dusty environment.
NOTICE
If used for heating, switch off the air
circulation as soon as the temperature
in the cab is sufcient, otherwise the
cab keeps warming up and moisture
starts to condense on the windows.
Do not cover the air vent hole in the
cab, located down in the right rear
corner, in order that moisture does not
condense on the windows. Also, do not
operate the loader without a cab air
lter cartridge in place, the ventilation
system may collect excessive amounts
of dust.

3. Greasing of the loader
Greasing of pivot points is very important to avoid wear.
Most of the greasing points are on the loader boom. The
following table and pictures show the location of grease
nipples.
500 Series
1
Suitable lubrication interval depends heavily on operating
conditions. Check the need of lubrication at least after
every 10 hours of use. Add grease if the joints have
become dirty. Adequate lubrication of the joints must be
ensured. Lack of lubrication will cause the joints to wear
quickly.
Use general purpose machine grease. A grease gun is
needed to apply grease to grease nipples. All lubrication
nipples are standard R1/8” nipples. Replace any
damaged nipples.
Clean the end of the nipple before greasing and add only
a small amount of grease at a time. New lubricant will
push out dirt from joints. Wipe excess grease with a cloth.
