4.2. Oil Damper - Saw Blade Feed to the Cut
The oil damper relief valve allows for a continuous setting of the velocity of saw blade feed towards the cut or stabilizing the saw arm
in any position by mechanical closing. The optimum value of descent can be determined very easily by ear. The saw blade movement
must be noiseless, free from vibrations. Such a state can be achieved by reducing or increasing the pressure force (by the velocity of
saw arm descent). The prerequisite of setting the optimum pressure is selecting the correct saw blade velocity and the optimum size
of the saw blade teeth.

4.3. Mechanical Control of the Feed
The springs are pre-tensioned during the manufacture for a universal use, during which the arm smoothly rises and descends with a
force ration ideal for most applications. Especially when cutting sturdy full materials, it is useful to increase the blade feed using the
weight of the cast iron arm. This is facilitated by continuous loosening of the adjusting screw and pulling down of the springs. If cutting
only thin-walled sectional construction materials, it is, on the contrary, possible to pull up the springs by screwing-in the adjusting
screw, which leads to a smaller blade feed to the cut and, in particular, easier arm uplift. The adjusting screw moves easily in the
position, in which the arm is raised and the springs are not tensioned.
