operation and maintenance. It must be read by personnel concerned prior to starting
up and using the machine and be available at all times, to all operators.
If safety instructions are not complied with, it can lead to the risk of injury to yourself and
others as well as damage to the environment or the machine. Non-compliance to the
safety instructions can also lead to claims for damages becoming invalid.
New equipment - be careful!
It is very important to be careful when new equipment is to be used for the first time.
Incorrect mounting of equipment and operational errors can lead to expensive repair
work and operational losses.
Your warranty with Agriweld is not valid if the instructions in this operating manual are
not followed correctly.

THINK SAFETY!
Read the instruction manual and follow the instructions given.
Take care when hitching up or unhitching the machine to and from the tractor.
It is forbidden to allow any persons to sit or ride on the implement at any time.
The tractor should be fitted with enough front-end weights for stability and to maintain
secure steering.
Driving, steering and braking characteristics are influenced by mounted machines and
ballast weights. The operator must ensure adequate steering and braking ability.
Use the tractor’s position control when coupling the implement to the tractor.
Do not stand between tractor and implement while it is being raised.
The tractor's lower link arms should be stabilised before driving on a public road so that
the implement and tractor lower link arms do not touch the tyres during transport.
Make sure that all nuts and bolts are always fully tightened.
NEVER stand or work beneath a suspended load unless supported by chocks or stands
capable of carrying the implements weight and bulk.
The user is responsible for ensuring the implement complies with the law when driving on
public roads and to check the lighting units are in full working order.
Always lower the implement attached to a tractor whilst parked.
OPERATION AND ADJUSTMENT
1. Attach the Toolbar to the tractor using the 3-point linkage.
2. Adjust the lower Tractors lower linkage arms to ensure the Toolbar is running level
to allow optimum soil disturbance and to prolong the lifespan of the wearing
parts.
3. Please ensure that the implement is mounted correctly and locked into position.
4. Ensure that the relevant tractor spool is disengaged and couple the hydraulic
hose to the relevant hydraulic spool on your tractor. Check that the hydraulic
hose is free from damage and not in a position to fowl when lifting and lowering
the Toolbar on the tractor’s linkage.
5. Check that all nuts and bolts are firmly tightened.
6. Set the toolbars leg height as required.
7. Set the auto reset “trip” pressure to the relevant soil/environmental conditions
applicable for each use.

RULES OF CONDUCT FOR OPERATION
The following points must always be observed before the machine is started up and
during operation:
- Never leave the machine unattended.
- Check the machine regularly for oil leakage. Replace defective components
immediately.
- Do not use if any parts are found defective.
- Check the machine for dirt accumulation and keep the unit clean at all times.
- Perform regular maintenance checks to ensure faults are noticed.
- Perform a regular greasing routine. The machine needs to be well greased at
all times. The greasing points are clearly visible and marked on the toolbar.
*Experienced persons are classed as those individuals who have been trained, know
current knowledge and skills, or have participated in the use of the type of activity and
equipment for several years.

AUTO RESET HYDRAULIC CIRCUIT
The auto reset pressure is set at 7 bar for dispatch. You will need to adjust this setting to
your own conditions. In order for the auto reset mechanism to be effective, you will
need to set this relative to the types of conditions/weather/ working depth /soil type
etc. If you find that the legs trip too easily the pressure can easily be increased. If the
legs do not trip the pressure must be decreased to prevent damage to the machine.
Please see Charging Oil Pressure below for instructions.
PLEASE NOTE: The pressure will also need adjusting for different working locations as soil
conditions can vary. Agriweld accepts no liability for the incorrect setting of the auto
reset pressures and you must take responsibility for this yourself.
Prior to use, the pressure should be visually checked to ensure that it has not reduced or
whether adjustment is required. The pressure gauge is situated on top of the hydraulic
block and is clearly visible for your convenience. If for any reason the pressure has
reduced, the machine can still be operated but excessive tripping of the legs may
occur, and it will need re-charging from the tractor.

HYDRAULIC SYSTEM SAFETY
The hydraulic system is working under high pressure and is therefore hot and potentially
very dangerous. It is very important that all hoses and connections are checked
frequently for leakage and external damage.
The hydraulic hoses should not be connected to or removed from the hydraulic system
on the tractor unless the oil pressure in both the tractor and implement has been
released.
Porous and defective hoses must always be replaced immediately.
Oil leakage from damaged hoses and connections can cause fatal injury and possible
fire risk.
Always seek medical treatment immediately following any injury.
RE-CHARGING OIL PRESSURE
*Experienced and / or qualified individuals only should perform this operation.
Connect the hydraulic pipe situated on the headstock and attached to the valve
block, to the relevant tractor spool. Open the tap on the feed pipe and operate the
tractor spool to pump oil into the system until the gauge needle reaches the required
pressure (bars). The pressure can be dropped by operating the spool the other way to
let the oil back out. Once desired pressure is reached turn tap back to lock the
pressure. The feed pipe can stay connected.

REPLACING THE POINTS
Always replace the points on solid ground e.g. cement/tarmac, to avoid the risk of
sinking and potential injuries whilst changing the points. The implement must be raised
on the tractor linkage and the tractor engine turned off. Remember to use the parking
brake and/or wheel chocks to ensure that the tractor is held stable. It is important to
support the Toolbars weight with stands/chocks in the event of failure of the tractor
hydraulics. Remember it is forbidden to work under a suspended load without the
adequate support.
Once you are confident that you have met the safety standards required you can
proceed;
•Unbolt the single fixing (M10 x 50mm long bolt) from the worn point to free the
point. A new point can then be replaced into the same position using the same
size fixing. Ensure the bolt is fully tightened.
•When you have finished replacing the points, remove the supports/chocks in
order to proceed.
•Please see page 11 for Point Assembly.

WEARING PARTS
The wearing parts used on the Toolbar can vary although as standard we fit a one
piece point. Parts can be obtained through Agriweld Ltd directly or through your local
dealer.
Please quote the details on the type plate(s) as well as the machine’s serial no. on
every order for spare parts or accessories, or for enquiries of a technical nature.
The use of spare parts not supplied by Agriweld must be of the same type and style as
fitted to the machine from new to ensure problem free operation. Original spare parts
and accessories authorised by the manufacturer ensure safe and reliable operation.
The use of other parts may invalidate the liability of the manufacturer for any
consequences arising from such use.
Disposing of replaced parts/oil
The following points should be observed before replacing or disposing of parts.
- Replaced parts, which still function, should be cleaned and stored in an orderly
manner.
- Machine parts, which cannot be repaired should only be disposed of at
appropriate collecting points or be collected by a scrap metal dealer.
- So-called “valuable” materials should be disposed of in a proper way, i.e.
plastics, rubber, scrap metal, etc. should be recycled.
- Collect and dispose of old oil in accordance with the current regulations.
