The lever also releases the splitting function when it is moved towards (B) as illustrated. Thin wood material that is not to be split When cutting thin wood materials, you may cut several continuous lengths and let them fall into the splitting cradle without activating the splitting piston.

  • Page 27: Chain Sharpening

    Blunt chains and skewly sharpened chains entail great wear on the saw chain sword and risk of extra costs and complications. In order to avoid this, Duun VM420 is designed so that the saw chain always must be dismantled from the machine for any sharpening or replacement.
  • Page 29 Chain tensioning and adjustment of the chain lubrication 1 Chain tensioning Use gloves during work with the chain! The chain is tensioned by releasing the two nuts (B). Then screw (A) is tightened to tension the chain proper. Afterwards, the nuts (B) are tightened. If you prefer to replace the chain, this is done by releasing the screw A (first release the screws B) as far so at to allow the chain to be removed in the back for maintenance or replacement.

  • Page 33: Lubrication Points And Maintenance

    Lubrication points and maintenance VM420 has many bearing points, of which many are only subjected to easy loads and are therefore equipped with pre-lubricated ball-bearings. The other bearings are mainly flange bearings that require moderate lubrication. The main rule here is to avoid excessive lubrication and forcing of the oil seals in the bearings.
