Basic Circular Saw Principles
• The blade rotates on a spindle, and breaks through the timber, cutting on
a continuous stroke Fig.7.1.
• Slowly feed the workpiece towards the blade Fig.7.1, let the blade
do the cutting it is not necessary to force the material. When feeding
towards the blade hold the workpiece firmly and use the table to provide
support. Always use a push stick, keeping your hand well away from
the blade.
• For best results the blade must be sharp and in good condition. A
damaged or worn blade should always be replaced.
• Select the right blade for the job, depending on the type of material and
the cut to be made.
• Never attempt to use the machine without the crown guard and riving
knife in position. Always ensure that the crown guard and riving knife are
correctly adjusted to suit the size and type of workpiece and that they
are fully secured with the original fixings supplied.
7. Operation & Sawing Practice
TABLE 1: Basic applications
Ripping
When the timber is cut with the
grain, use the rip fence for this
application
Cross Cutting
When the timber is cut across the
grain, use either mitre fence or
sliding carriage for this application
Panel Sizing
Dimensioning man made sheet
material. Use either the rip fence or
sliding carriage for this application
Bevelled Edge
When a bevelled (angled) edge is
required to the workpiece tilt the
blade and pass the timber though.
If the rip fence is being used with
the blade tilted, the auxiliary fence
should be used in the low position
to prevent it fouling on the blade
and crown guard.
