Contact with current-carrying cables etc. during transport. Please note that the firewood processor can tip over the tractor during transport and there is a risk of contact with live wires, railway underpasses etc.! Conveyor belt – transporter Do not stay under the conveyor when it is tensioned to avoid damage of an uncontrolled fall during use.

Safe transportation Before the machine is moved, the feed belt and conveyor (both in the folded-up position as outlined) must be strapped together with a load strap to ensure that they cannot fall down. The loading stop has an attachment at the bottom of the feed belt and secures the belt from falling off during transport.

Hydraulic oil quality The machines' ability to function will mostly depend on the hydraulic oil being intact. The biggest dangers to oil quality are: • Too high a temperature, which is accompanied by poor lubrication and the risk of malfunctions and damage to expensive components such as valves, pumps and motors.
NB! Too long shaft can lead to spraining of the shaft and risk of overloading the tractor's PTO and the gearbox in VM450. Please lubricate the power transmission shaft before use. The locking chains for the protective covers must always be attached to suitable fasteners to prevent the covers from rotating.
Feeding belt preparation Fold the feed belt into place by loosening the locking pin at point G which locks it off. The band is tightened by adjusting the screws at point H. The band is sufficiently tensioned if it feeds the wood without slurping.
Practical use Conditions The machine must not be used until the operator has carried out the following: • Has read the instruction manual and knows how the machine works and how to control it. • Has familiarized himself with and aligned himself with the information about safety described on pages 4 to 7 of the instruction manual.
The main functions-feeding- conveyor belt speed regulation The material to be cut is fed onto the infeed belt. The main functions are: A. Move the feeding belt forward/backward. B. Operate the cutting blade up and down. C. Triggering of cutting. D.
Hydraulic knife lift The splitting knife is adjusted up and down with the handle K. To change the knife, run the knife all the way to the top. Loosen the bolt that holds the knife in the lower edge and lift out. Stuck material If the splitter is unable to split the wood - the piston is driven back by moving the joystick...
Blunt chains and skewly sharpened chains entail great wear on the saw chain sword and risk of extra costs and complications. To avoid this, the Duun VM450 is designed that the saw chain must always be removed from the machine for sharpening or replacement.
To change the chain, loosen both screws B. The screw A is loosened so far that the chain can be unhooked at the rear for maintenance or replacement. To tighten the chain, loosen screws B and tighten with screw A. Check the chain tension by pulling the chain in the middle of the long side of the bar.
Service and maintenance Before opening any covers and carrying out service and maintenance, always switch off the machine to avoid damage. NB! There are movable parts in the mechanism with great power and a risk of crushing. The machine should never be run with the covers removed. The machine is factory set.
Weekly maintenance Open all lids and safety covers and blow clean of dirt and grime. Sawdust and dirt will settle inside the machine and it is important to remove this in order for the machine to have optimal cooling and for all functions to work.

Item no. 2251065 Clean and lubricate the machine properly between each season. The VM450 has many bearing points, many of which are lightly loaded and are therefore equipped with one-time lubricated bearings. Other bearings are mainly flanged bearings that should be moderately lubricated. The main rule here...
