Storage / Profi DOR and Profi DOR s.c. Storing Profi DOR and Profi DOR s.c. with a fork lift truck

Use all adjustments to move the side members together and inwards to make the Trimmer as compact as possible. Fold both horizontal boards to the rear.

Pick up the storage frame with the fork-lift truck and drive it to face the Trimmer.

Now raise the storage frame.

Take care that the two lifts are correctly aligned with the lower hooks of the storage frame.

Then secure the Trimmer with the security screw to the storage frame

Unscrew Trimmer mounting plate from the mounting bracket.

Now raise storage frame to engage the Trimmer on the locating hooks

You can now move the Trimmer easily with a hand pallet truck or a fork-lift truck. The Trimmer may only be transported and stored on level surfaces. 47

Storage / Storage without Multi Mast Storage without Multi Mast

If you want to store the Trimmer without its mast, all hydraulic hoses connected to the Trimmer must be fitted with plug-in couplings.

Disconnect the Trimmer’s plugin couplings from the controller, bundle them and secure them to the Trimmer. Take care that plug-in couplings don’t get dirty during storage. Then you can remove Trimmer from the mast & store it separately.

When reassembling always connect plug-in couplings with the same colour. Green -> Green Yellow -> Yellow … etc. Double check correct connection of the plug-in couplings.

MAINTENANCE

Maintenance/ Basics Maintenance The maintenance and commissioning of modern devices and safety-relevant components require qualified training and a workshop with special tools and test devices. The specialist has the necessary training, experience, equipment and original repair instructions. He will always offer you the least expensive solution. He will give you help and advice. Repair attempts by third parties or unauthorised persons will void the guarantee. The ERO Vine Trimmer is almost maintenance-free. However, during cutting work •• The saw blades, NOTICE •• The hydraulic hoses and Only genuine ERO spare parts may be used to •• The electric cables replace any parts, otherwise guarantee will be voided. should be checked regularly. The ERO Vine Trimmer Elite is practically maintenance-free. However, the turbo blades and V-belt should be checked regularly during the vine trimming work.

Maintenance/ V-belt The v-belts are to be checked regularly for the proper tension and re-tensioned when necessary. Always tension the whole unit from top to bottom! Checking V-belt tension

Push the v-belt through with a folding ruler: The measurement reading at the housingâ&#x20AC;&#x2122;s edge should be 30-35mm maximum.

Re-tensioning V-belt

Loosen the first bearing stack locking nut on the exterior of the side section with a fork spanner. At the same time, hold the bearing shaft on the inside of the vine trimmer with a fork spanner.

Tension the bearing stack by knocking the locking nut downward with a plastic-faced hammer. If the bearing stack slips out of its starting position after tensioning, then the locking nut was loosened too much: Tighten it somewhat and repeat tensioning procedure. Re-tighten the locking nut with a maximum torque of 50 - 55 Nm and open the next bearing stack. 51

Pressure-relief valve Duplex manifold block Leak-oil container

As soon as the pressure in the leak-oil hoses is greater than 4-5 bar, the pressure-relief valve (DBV) on the duplex manifold block opens. To relieve pressure, the excess hydraulic oil is released into the leak-oil container through a leak-oil hose. This prevents damage to the hydraulic motors. Check the level in the leak-oil container several times a day.

Leak-oil container emptying After cleaning the machine (or whenever necessary) empty the leak-oil container on the head of the Trimmer. 1.

Lift the leak-oil container upwards out of its holder, hold it firmly with one hand.

Unscrew the lid and empty the leak oil out of the leak-oil container.

Then screw the lid back on and replace the leak oil container in its holder.

Should you find an unusually large quantity of hydraulic oil has collected in the leak-oil container in a short time, then the leak-oil pressure in the system is too high. Reasons for increased leak-oil pressure: •• Too much hydraulic oil (incorrect setting of flow-control valve) •• Hydraulic oil too cold (temperature should be above 50°C) 52

•• Plug-in coupling on return line is not correctly assembled. •• The plug-in coupling on the return line is damaged. •• The return hose is kinked or crushed.
