The front of the base is placed on the workpiece for cutting without any
contact with the saw blade. Then start the tool according to the switch
operation and wait until the saw blade reaches full speed. Now, gently
press the circular saw head down to the preset cutting depth, then simply
move the tool forward on the surface of the workpiece to keep it smooth
and flat until the cutting operation is complete.
To make the cutting cleaner, make sure the tool cuts in a straight line and
at a consistent forward speed. If the actual cutting line is different from the
planned cutting line, do not attempt to turn or push the tool back to the
originally planned cutting line. Doing so may cause the saw blade to get
stuck and cause the tool to bounce or possibly cause serious injury.
Release the switch, wait for the saw blade to stop and then pull back the
tool. Align the tool with the new cutting line and start cutting again. When
determining the cutting position, try to avoid exposing the operator to
debris and sawdust sprayed by the chainsaw. Wear safety goggles to avoid
injury.
 When using guide rail (optional accessories)
Place the tool at the end of the guide rail. Turn the two eccentric wheels on
the tool base so that the tool can slide smoothly. Hold on to the tools. The
tool is equipped with both a secondary handle and a handle. Using both
handles at the same time is the best way to grip the tool. Open the tool,
press the tool down to the preset cutting depth (the B scale line on the
depth adjustment board corresponds to the cutting depth when there is a
guide rail), and then cut.
