CUTTING FEED RATE/ SAW ARM TENSION
A hydraulic cylinder allows adjustments to the downfeed speed of the arm to control cutting speed.
Note: The valve must be open in order to adjust the cutting feed rate.
- Turn the knob A clockwise to increase the cutting
feed rate.
- Turn the knob A counterclockwise to reduce the
cutting feed rate.
Note: Forcing the blade into the workpiece increases the
risk of blade breakage and can affect the quality of the cut
(burrs, chips, etc.).
A tension spring helps lift the arm into the the vertical
position and slows down its descent. If too little tension
makes it difficult to raise the arm, proceed as follow:
1. Loosen the jam nut B and tighten bolt C a few turns.
2. Repeat as needed until the desired tension is
achieved and then retighten the jam nut B.
Note: For less tension, loosen bolt C.

The switch A allows you to turn the coolant system pump
on or off. You can also stop the flow of the liquid coolant
by closing the valve B.
Make sure that the level of liquid coolant in the tank-
located under the work table is between 3 liters (mini-
mum) and 5 liters (maximum).
Don’t start the pump during vertical cuts.
Note: To reduce the risk of blade breakage and obtain
cleaner cuts, always use the coolant system except for ver-
tical cuts.
