HOW TO WORK SAFELY
An incorrect or careless operation of the loader may
be the origin of a serious accident. Before putting the
machine into operation, familiarise yourself with the
use of the machine and read and understand this
Operators Manual as well as the safety instructions.
THIS SYMBOL INDICATES
THE IMPORTANT
SAFETY FACTORS.
Understand the limitations of speed, braking, steering
and stability as well as loading capacity of the machine
before starting operation.
If you have no previous experience of the machine,
make sure to do all testing at a safe and open place
with no persons in the area of operation.
SAFETY INSTRUCTIONS
Never use the loader without instructions. Read loader
signs (decals), and this manual.
Start the operation slowly and carefully.
Do not wear loose clothing, long uncovered hair or
jewelry near machine.
When driving be comfortably seated in the driver´s
seat, keep your feet in their proper place in the footwell
and both hands on the control levers.
Operate the control levers and the lever of auxiliary
hydraulics only when sitting in the driver´s seat.
Operate the control levers with ease and without
hesitation.
When coupling the attachment, make sure that the
locking pins lock in positively.
Never put any part of the body or let anyone go under
the lifted boom.
Do not transport persons in the bucket. The machine
is not designed to lift or to transport persons.
Keep hands, feet and clothing away from any moving
part and/or hydraulic cylinder.
Never carry passengers. Keep other bystanders away
from the work area.
Drive slowly on uneven terrains. Watch out for ditches,
manholes and steep gradients.
Do not drive on too steep a gradient. Load, unload, and
turn on flat level ground.
Make sure that the ventilation is sufficient when working
indoors or otherwise confined area.
Do not use loader in an atmosphere with explosive dust
or gases or where exhaust can contact flammable
material, explosion or fire can result.
Do not transport the load with the boom lifted.
Always carry bucket or attachment as low as possible,
and put the load down whenever you leave the machine.
When lifting or lowering the load, do not operate the
boom control lever abruptly. Turn the lever smoothly
and with care.
Do not exceed rated operating capacity - follow the
load diagrams.
Do not park the machine on a surface with a gradient.
Should this be necessary, use the parking brake and
preferably turn the machine sideways and put down
the bucket. If needed, use chocks behind the wheels.
Before leaving driver´s seat:
- Lower the loader boom
- Place attachment flat on ground
- Stop the engine, remove the key
- Engage the parking brake
Never perform any maintenance or repair operation
when the engine is running.
Stop and cool the engine before adding fuel.
Never use ether or starting fluid on diesel engines with
glow plugs. Use only starting aids as approved by engine
manufacturer.
Keep the engine area clean of flammable materials.
Wear eye protection when servicing, and hard hat or
other protective equipment as needed.
When connecting a booster battery for "jump" start,
always make last connection (negative cable) to engine,
never at battery. When removing the "jump" start cable,
always remove the negative cable (-) from engine first.
Never charge a frozen battery.
Lead acid batteries produce flammable and explosive
gases. Keep arcs, sparks, flames and lighted tobacco
away from battery.
Battery acid causes severe burns. In case of acid contact,
wash immediately with water for several minutes and
get medical attention in case of eye contact.
Use a piece of cardboard to check for hydraulic leaks.
Leaking fluids under pressure can enter the skin and
cause serious injury. Medical attention is required if
hydraulic or other fluids contact skin.
Never modify the loader or add attachments not
approved by AVA NT Tecno Oy.
Do not smoke during refueling or driving.
Read this Operator's Manual carefully, especially if you
are unfamiliar with the safe use and operation of the
machine.

300S Series
LOAD DIA RAM
The lifting capacity of the loader is limited by the possibility of tipping around the front axle. The diagram
below shows the tipping loads and max. allowed loads in different loading situations on an even level surface.
AVANT 313S load diagram
The diagrams can be interpreted as follows:
 If the load is 25 cm in front of the attachment coupling plate, the max. load for the model 313S with 13 hp
petrol engine is 310 kg for the loader with a driver weighing 80 kg. For the 314S model the max. load is
400 kg, for the 320S and 320S+ models the max. load is 460 kg.
 If the load is still 25 cm in front of the attachment coupling plate and a rear weight of 30 kg is added, the
max. load increases to 350 kg for the 313S petrol model. For the 314S diesel model the max. load is
440 kg, and for the 320S and 320S+ models the max. load is 510 kg.
CAUTION! In practice the safe working load is 70 % of the diagram values. Do not load the
loader with heavier loads than this.
ALWAYS PUT DOWN THE LOAD BEFORE LEAVIN THE MACHINE.

 Turn the ignition key to the OFF position (to the left)
 Turn the power off with the battery disconnect switch
NOTICE! The engine cannot start if the auxiliary hydraulics
control lever is in locking position or the pump selection
lever (on model 320S+) is in the position 2-pump (when
the ambient temperature is low)
STOPPIN THE EN INE
DRIVE CONTROL
Start the engine as explained on previous pages. When
starting the engine do not touch any control lever.
After starting the engine take a firm grip on the control
levers (see picture on the right). It is important to use
exactly this grip, it gives you the best possible feel on
the levers and control on the machine. This way you
will be able to control the machine smoothly and
securely right from the start.
Driving forward
Select first moderate engine revs by pressing the
throttle pedal and push carefully both drive control
levers forward until they are completely in the forward
position. The machine starts to go straight forward.
Do some training by repeating this movement so that
the machine starts smoothly  if you operate the
control levers abrubtly the movements will be jerky.
Drive speed can be increased with the throttle pedal.
The machine will stop as soon as one allows the levers
to return to center (neutral) position.
Reverse driving
Reverse driving happens exactly the same way as
driving forward, except that the drive control levers
are now being pulled backwards. Drive speed can be
increased with the throttle pedal. The machine will
stop as soon as one allows the levers to return to
center (neutral) position.
Turning
Turning of the machine is based on the skid steer
principle. When you want to turn the machine to a
direction, push/pull the drive control lever less on
the inner curve side. By doing this the inner wheels
brake and and consequently the machine turns.
If you want to turn the machine on the spot, push one
side drive control lever and pull the other side control
lever to the extreme end position.
Loader control
Loader boom and bucket tilt functions are operated
with the same multi-function levers as drive, by turning
them sideways.
Right side lever is for boom control
Push right to lower the boom
Push left to lift the boom
Left side lever is for attachment
(e.g. bucket) tilt control
Push right to lower the tip of the bucket
Push left to raise the tip of the bucket
Memory helper: By turning both levers inwards both
boom and tip of bucket rise.

THE OPERATIN DIRECTION OF
THE ATTACHMENT DEPENDS ON
THE COUPLIN OF THE
ATTACHMENT HOSES. MAKE SURE
THAT THERE ARE NO PERSONS IN
THE DAN ER AREA WHEN
TESTIN THE OPERATIN
DIRECTIONS. CHAN E THE
COUPLIN OF THE HOSES IF
NECESSARY.
DOUBLE SPEED PEDAL
Models 313S, 314S and 320S
have a double speed function
(optional extra) which is operated
with a pedal in the footwell (see
picture). Double speed can be
engaged either before starting
driving or while driving. It can also
be disengaged at any time during
driving or after the driving by
lifting the foot off the pedal.
Double speed function doubles
the driving speed. It is intended
for long transitions, where higher
drive speed can safely be used.
NOTICE! When using double
speed the oil flow to the drive
hydraulic motors is bigger and therefore the pulling
force is smaller. When turning use the lower speed in
order that the machine turns more easily.
Double speed on model 320S+: On 320S+ double
speed is selected with the pump selection lever on
the left on the dashboard. Push the lever forward to
engage the double speed function.
ATTENTION! Do not start to drive with the machine
before you have read and understood the instructions
in this Operators Manual. If you are uncertain of the
conduct of the machine please contact your AVA NT
dealer for instructions.
USIN THE AUXILIARY HYDRAULICS
On models 313S, 314S and
320S auxiliary hydraulics
(hydraulically operated
attachments) are controlled
either with the control lever
no. 3 on the dashboard or
with the pedal no. 3 on the
left in the footwell (see pages
12 and 13). The lever can be
locked in the up right
position, in case continuous
oil flow for the attachment
is required (e.g. with
backhoe, rotary broom etc.).
On model 320S+ auxiliary
hydraulics are controlled
with the lever no. 2 in the
footwell left (see page 13).
When pulling the auxiliary
hydraulics control lever upwards it locks into the
locking position. This facilitates the use of those
attachments that require constant oil flow, the rotary
brush for example. If the lever must not lock into the
locking position (e.g. with the silage fork), tighten the
black round screw in the lever so that the spring load
always brings the lever back in the middle position.
On 320S+ the oil flow to auxiliary hydraulics depends
on the position of the pump selection lever on the left
on the dashboard. When the pump selection lever is
in the back position, the flow of one pump
(22,5 l/min) is selected for auxiliary hydraulics and one
can drive the machine on the lower speed at the same
time (e.g. when operating a rotary broom). When the
selection lever is in the front position, both pumps
are coupled and one can either operate the auxiliary
hydraulics with the flow of both pumps (45 l/min) or
drive the machine on double speed, but not both.
NEVER TIP OVER THE LOADER.
NEVER USE A HI H DRIVE SPEED
WHEN TURNIN .
In particular: when the loader boom is up
the stability of the machine is much weaker
when turning.
WHEN DRIVIN , 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.
ALWAYS REMEMBER 
SAFETY FIRST.
TEST ALL THE FUNCTIONS OF THE
LOADER AT AN OPEN AND SAFE
PLACE.
MAKE SURE THAT THERE ARE NO
PERSONS IN THE OPERATIN
AREA OF THE MACHINE.

coupling plate and turn them backward so that they remain
in the locked up position
 Make sure that the pins remain in the up position, otherwise
you cannot couple the attachment properly!
Stage 2:
 Turn the attachment coupling plate with the tilt movement
so that the upper edge of the plate leans forward.
 Drive the loader into the attachment
Stage 3:
 Lift the boom a little so that the attachment lifts off of the
ground
 Pull the boom control lever to the left so that the lower edge
of the attachment coupling plate turns into the attachment
Stage 4:
 Pull the boom control lever more to the left so that attachment
coupling plate turns more and the bolts on the boom push
the pins down in the holes of the attachment.
CAUTION! Make sure that the pins lock properly
down in the holes of the attachment.
Stage 5:
 If the attachment is equipped with hydraulic hoses, make
sure to connect the hoses in the quick couplings on the loader
 Engine must be stopped when connecting the hoses. Before
connecting the hoses move the auxiliary hydraulics control
lever in both directions a couple of times in order to release
eventual back pressure.
 Additional information about the coupling is provided in the
instruction manual of the attachment.
NOTICE! When fitting an attachment, make sure that
the hydraulic hoses are not overstretched and are not
in a position where they can be trapped during the
operation of the machine and attachment.

300S Series Safety instructions for maintenance
SAFETY INSTRUCTIONS FOR MAINTENANCE
Hydraulic oil tank is located on the front axle as a part of the
front chassis, so in order to get to the dipstick and return oil
filter the boom must be lifted and the front cover plate removed.
Make sure that the boom stays up by putting the service support
on the lift cylinder piston rod.
The red service support is located behind the attachment
coupling plate, fastened with a bolt
Make sure to secure the service support by locking it on the
piston rod by the bolt
ALWAYS REMEMBER SAFETY DURIN MAINTENANCE
DO NOT PERFORM ANY SERVICE OPERATION WHEN THE EN INE
IS RUNNIN
USE THE SERVICE SUPPORT ON THE BOOM CYLINDER
DO NOT O UNDER UNDSUPPORTED BOOM
DO NOT SMOKE DURIN SERVICE OPERATIONS
BEWARE POSSIBLE HI H PRESSURE IN HYDRAULIC CIRCUITS
MOUNTIN OF THE SERVICE SUPPORT
SAFETY INSTRUCTIONS WHEN HANDLIN THE BATTERY
- BATTERY CONTAINS CORROSIVE SULFURIC ACID.
- AVOID CONTACT WITH SKIN OR CLOTHES. IF ELECTROLYTE ETS
ON YOUR SKIN OR CLOTHES, FLUSH WITH A LOT OF WATER.
- IN CASE OF CONTACT WITH EYES, FLUSH WITH A LOT OF WATER
FOR AT LEAST 15 MINUTES AND CALL A DOCTOR IMMEDIATELY.
- WHEN CHAR IN THE BATTERY IVES OFF POTENTIALLY EXPLOSIVE
ASES  DO NOT SMOKE WHEN HANDLIN THE BATTERY.
- IN ORDER TO AVOID SPARK EMISSIONS ALWAYS DISCONNECT THE
NE ATIVE (-) CABLE FIRST AND CONNECT IT LAST.
- BEFORE CONNECTIN THE BATTERY CABLES MAKE SURE THAT THE
POLARITY IS CORRECT: FAULTY CONNECTION WILL SERIOUSLY
DAMA E THE ELECTRIC SYSTEM OF THE EN INE.

1. CLEANIN THE LOADER
leanliness of the loader is not only a question of
outer appearance. All surfaces, painted and others,
will stay in better condition when they are cleaned
regularly. A clean machine also lasts longer. A dirty
machine will run hotter and will collect dirt into the
air cleaner, which is likely to damage the engine. Pay
special attention to the cleanliness of the engine, the
oil tank cover, the engine compartment and the
hydraulic pump compartment.
The loader can be washed with a pressure washer.
2. TYRE PRESSURE
orrect tyre pressure
means that the tyres last
much longer. Wrong tyre
pressure increases tyre wear
and can be a safety risk
when working with the
loader.
Recommended tyre
pressures are:
- 4.00 - 12 tyre 2.8 bar (40.6 PSI)
- 5.00 - 10 tyre 2.8 bar (40.6 PSI)
- 20*8.00-10 tyre 2.8 bar (40.6 PSI)
- 23*8.50-12 tyre 2.5 bar (36.3 PSI)
3. BATTERY CHECK
In order to secure the
starting and safe operation
the battery of the loader
must be checked regularly.
hecking the electrolyte
level of the battery happens
by opening the filler caps.
ATTENTION! lean the battery before opening the
caps so that dirt cannot get in the battery.
heck also the contacts and clean if necessary.
4. HYDRAULIC OIL LEVEL
Hydraulic oil level can be
checked with the dipstick in
the filler. Oil level should be
between the two marks in
the dipstick. Refill when
necessary. lean the area
before checking hydraulic
oil level. Do not let any
contaminents enter the
hydraulic oil tank during this
procedure.
5.CHAN IN OF HYDRAULIC OIL FILTER
The hydraulic oil return filter is located on top of the
hydraulic oil tank, under the cover. Take off the cover
and replace the oil filter cartridge.
Remember to use the service support.
6. HYDRAULIC OIL CHAN E
When changing hydraulic oil, the oil can be removed
with a suction pump or by opening the drain plug on
the front of the frame, between the front drive motors.
In both cases it is important to clean the magnetic
drain plug.
Hydraulic oil capacity is 51 litres. Use ISO VG-46
certified mineral hydraulic oil (e.g. Shell Tellus TX oil).
Use of synthetic hydraulic fluids is not allowed.
7. CHECK AND TI HTENIN OF
BOLTS, NUTS AND FITTIN S
heck tightness of bolts, nuts and hydraulic fittings
regularly.
ATTENTION! Tighten wheel nuts after first 5
operating hours. heck tightness of wheel nuts
regularly. Wheel nuts shall first be to 120 Nm diagonally
opposite and finally tightened to 140 Nm.
8. CHECKIN THE HYDRAULIC SYSTEM
PRESSURE
orrect pressure in hydraulic
system is of vital importance.
Too high pressure can
seriously damage the
hydraulic system. Too low
pressure on the other hand
means low performance: the
capacity of the hydraulic
system is not being used as
it should.
Hydraulic pressure settings:
- 313S, 314S: 175 bar
- 320S: 210 bar (drive),
200 bar (aux. hydr.)
- 320S+: 240 bar (drive),
200 bar (aux. hydr.)
