DISCONNECT MACHINE FROM POWER SOURCE.
Before starting the machine, make all adjustments and put all guards in place. Turn the upper wheel clockwise by hand to be
sure that everything is correct before providing power to the tool.
Keep the top guide close to the work. Do not force the material against the blade. Light contact with the blade will permit eas-
ier following of the line and will prevent excess friction, heating, and work-hardening of the blade at its back edge.
Keep the saw blade sharp and very little pressure will be required for average cutting.
Avoid twisting the blade by turning abrupt corners.
When cutting curves, turn the stock carefully so that the blade may follow without being twisted. If a curve is so abrupt that
repeated new kerfs are needed, then use either a narrower blade or one that has more set. The more set a blade has, the
easier the stock is to turn. However, the cut is usually rougher than when using a medium set.
When withdrawing the blade, be careful not to draw the blade off of the wheels. In most cases, it is easier and safer to turn the
workpiece and saw out through waste material. Do not back the blade out while the saw is running.
