Palmgren Operating Manual & Parts List
OPERATION (CONTINUED)
SETTING UP THE MACHINE FOR OPERATION
Refer to Figure 12.
1. Select the proper speed and blade for the type of material you
are cutting.
2. Make sure blade tension is adjusted properly.
3. Lift the saw bow up and close the feed control valve.
4. Place the stock between the vise jaws, set the stock for the
desired width of cut and tighten the vise.
5. Make sure the left blade guide bracket is adjusted as close as
possible to the left vise jaw.
6. Turn the feed control valve counterclockwise until the saw blade
begins to lower the desired rate of speed.
7. Proceed to cut through the workpiece. The machine will shut off
upon completion of cut.

CHANGING SPEEDS
Your machine is provided with a range of speeds, 80 to 250 SFPM. To
change speeds, proceed as follows:
1. Machine must be running.
2. Use speed selector as shown in Figure 13. Turn to desired speed.
Figure 13 – Blade speed selector.
CUTTING AND ADVANCE SPEED
The cutting speed (in/min) and the advance speed (in2/min = area
traveled by the blade teeth when removing shavings) are limited by
heat build up on the tips of the teeth.
•
The cutting speed is dictated by the resistance of the material (R
N/mm2), its hardness (HRC) and its dimensions in the widest
section.
•
An advance speed (= lowering of the saw bow) set too fast tends
to cause the blade to deviate from the ideal cutting path,
producing misaligned cuts on both the vertical and the
horizontal plane.
•
The best way to determine the proficiency of these two
parameters is to examine the chips from the cut.
•
Long spiral-shaped chips indicate ideal cutting.
•
Very fine or pulverized chips indicate lack of feed and/or cutting
pressure.
•
Thick and/or blue chips indicate overload of the blade.
