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.

LOAD DIAGRAM
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 LEAVING 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)
STOPPING THE ENGINE
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.
Double speed
16
NOTICE! THE ENGINE CANNOT START IF THE AUXILIARY HYDRAULICS CONTROL LEVER IS IN THE LOCKING POSITION.
THE OPERATING DIRECTION OF THE ATTACHMENT DEPENDS ON THE COUPLING OF THE ATTACHMENT HOSES. MAKE SURE THAT THERE ARE NO PERSONS IN THE DANGER AREA WHEN TESTING THE OPERATING DIRECTIONS. CHANGE THE COUPLING 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.
USING 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 HIGH DRIVE SPEED WHEN TURNING.
In particular: when the loader boom is up the stability of the machine is much weaker when turning.
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.
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 OPERATING AREA OF THE MACHINE.

Coupling the attachments
COUPLING THE ATTACHMENTS
Coupling of the attachments into the attachment coupling plate happens as follows:
Stage 1:
 Lift up the two locking pins on either side of the attachment
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.

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 DURING MAINTENANCE DO NOT PERFORM ANY SERVICE OPERATION WHEN THE ENGINE
IS RUNNING USE THE SERVICE SUPPORT ON THE BOOM CYLINDER DO NOT GO UNDER UNDSUPPORTED BOOM DO NOT SMOKE DURING SERVICE OPERATIONS BEWARE POSSIBLE HIGH PRESSURE IN HYDRAULIC CIRCUITS

- IN CASE OF CONTACT WITH EYES, FLUSH WITH A LOT OF WATER FOR AT LEAST 15 MINUTES AND CALL A DOCTOR IMMEDIATELY.
- WHEN CHARGING THE BATTERY GIVES OFF POTENTIALLY EXPLOSIVE GASES  DO NOT SMOKE WHEN HANDLING THE BATTERY.
- IN ORDER TO AVOID SPARK EMISSIONS ALWAYS DISCONNECT THE NEGATIVE (-) CABLE FIRST AND CONNECT IT LAST.
- BEFORE CONNECTING THE BATTERY CABLES MAKE SURE THAT THE POLARITY IS CORRECT: FAULTY CONNECTION WILL SERIOUSLY DAMAGE THE ELECTRIC SYSTEM OF THE ENGINE.
1. CLEANING THE LOADER
Cleanliness 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
Correct 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. Checking the electrolyte level of the battery happens by opening the filler caps. ATTENTION! Clean the battery before opening the caps so that dirt cannot get in the battery. Check 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. Clean the area before checking hydraulic oil level. Do not let any contaminents enter the hydraulic oil tank during this procedure.
5.CHANGING 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 CHANGE
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 TIGHTENING OF BOLTS, NUTS AND FITTINGS
Check tightness of bolts, nuts and hydraulic fittings regularly. ATTENTION! Tighten wheel nuts after first 5 operating hours. Check tightness of wheel nuts regularly. Wheel nuts shall first be to 120 Nm diagonally opposite and finally tightened to 140 Nm.
8. CHECKING THE HYDRAULIC SYSTEM PRESSURE
Correct 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.)

WARRANTY DOES NOT COVER DAMAGES CAUSED BY EXCESSIVE HYDRAULIC PRESSURE.
NEVER EXCEED THE RECOMMENDED HYDRAULIC PRESSURE SETTINGS. EXCESSIVE HYDRAULIC PRESSURE WILL DAMAGE THE HYDRAULIC PUMPS, CYLINDERS, AND HYDRAULIC MOTORS.
Measuring the hydraulic system pressure:
System pressure is measured from the female auxiliary hydraulics quick coupling, with full revs and by turning the aux. hydraulics control lever. ATTENTION! It is recommended that pressures should only be checked and adjusted by a competent and experienced technician. Call your AVA NT dealer if you need assistance.
9. ADJUSTING THE HYDRAULIC SYSTEM PRESSURE:
If the pressure of hydraulic system does not seem to be correct or pressure check indicates that the pressure is wrong, it can be adjusted.
On models 313S, 314S and 320S pressure is adjusted from the pressure relief valve at the main control valve (see picture). Adjustment screw is under the cap, adjustment with hexagonal head key. On model 320S+ pressure for auxiliary hydraulics is adjusted from the pressure relief valve at the aux. hydraulics control valve (in the footwell, remove the front cover plate in order to get to the valve). Pressure for drive is adjusted from the pressure relief valve at the main control valve.
10. GREASING OF THE MACHINE
Greasing of pivot points is very important in order to avoid wear. Most of the greasing points are on the loader boom. There are 8 grease nipples altogether on a machine with standard boom and 14 grease nipples on a machine with telescopic boom. The picture on page 22 shows the location of grease nipples.
11.-18. SERVICE, PETROL ENGINE
AVA NT 313S is equipped with the Honda GX390 petrol engine. Service and maintenance instructions for this engine can be found in the Honda Operators Manual supplied with the loader.
19.-32. SERVICE, DIESEL ENGINE
AVA NT 314S is equipped with the Kubota Z482 2 cylinder diesel engine, 320S and 320S+ are equipped with the Kubota D722 3 cylinder diesel engine (see technical specification sheet for the engine type of each model). Service and maintenance instructions for the engines can be found in the Kubota Operators Manual supplied with the loader.
REFUELING
Petrol engine: Check fuel level
and fill the tank if necessary. Never use petrol mixed with oil or unclean petrol. Use unleaded petrol only, see also Honda Owners Manual.
Diesel engine: Check fuel level and fill the tank if necessary. Use diesel fuel only, in accordance with the instructions in the Kubota engine Operators Manual. Use of other fuels is not allowed, because their quality and properties cannot be guaranteed. Make sure not to let the fuel tank get empty. Should this happen, refuel and restart  the engine is fitted with automatic fuel bleeding.
DO NOT SPILL FUEL WHEN REFUELING. SHOULD THIS HAPPEN, WIPE THE FUEL AWAY IMMEDIATELY IN ORDER TO AVOID RISK OF FIRE.
ALWAYS STOP THE ENGINE BEFORE REFUELING. KEEP THE ENGINE AWAY FROM OPEN FIRE.

TROUBLESHOOTING
Following table shows the most common problems and the solutions to them. There are more instructions and troubleshooting advice concerning the engines in the Owners Manual of the engine (Honda or Kubota).
Problem
Hydraulic attachment does not work when the auxiliary hydraulics control lever is moved
Engine does not start.
Attachment hoses will not go into the quick couplers of the machine.
The machine moves after parking brake has been engaged.
Cause
Attachment hoses are not coupled or they are coupled wrongly in the quick couplers.
Faulty or damaged quick couplers (will restrict or stop oil flow).
No fuel Auxiliary hydraulics control lever (lever no. 3, page 12) is in locking position.
There is back pressure in the auxiliary hydraulics line.
The pins of the parking brake mechanism have not locked properly in the wheels.
Remedy
Make sure that the hoses are properly connected into the quick couplers, change the place of the hoses if necessary. Auxiliary hydraulics have double acting pressure couplers (female) and a return line (male coupler) Operating direction of the attachment depends on how the hoses are connected in the quick couplers. Replace quick couplers.
Fill the tank and start the engine. Diesel engines have automatic fuel bleeding  just glow and restart. Turn the lever in center (neutral) position
Release the pressure by moving the auxiliary hydraulics control lever in both directions.
Drive slowly forward or backward in order to lock the parking brake. When releasing the parking brake do this in opposite order.
