Some helpful tips when using the chop saw
•Disc selection. The cutting disc must match the material to be cut. There are a wide variety of cutting discs and careful selection will assist in the correct and safe operation of the saw. For example, select a masonry cutting disc for bricks and tiles, a bar cutting disc for cutting solid metal section and a metal stud cutting disc for cutting steel sections. General purpose metal cutting discs are also available but where possible it is better to use the correct cutting disc for the task being performed.
•Abrasive cutting discs wear. The cutting discs wear so as to constantly expose to the material being cut clean and sharp cutting edges. This is normal for this type of cutter.
•During the cutting operation apply a constant and even pressure to the cutting arm. The disc should be constantly cutting, and sufficient pressure needs to be applied to keep the cutting action going. If insufficient pressure is applied, the wheel has a tendency to clog, and the cutting edges of the disc become blunt and the cutting process reduces considerably. This is called glazing of the wheel and is due to the incorrect cutting disc for the material being cut, or the cutting rate being too slow.
•Do not overload the saw. The saw should run during the cutting operation at close to full speed. Too much pressure being applied to the tool will slow the motor and can cause motor failure.
•Too much pressure being applied to the tool can also cause the cutting disc to cut on an angle. Ensure the beginning of the cut is a gradual start and apply the firm and constant pressure as the cut gets deeper.
•When cutting sections, always try and cut the sections so as the actual cutting length is as short as possible through the section. For example, angle iron has two sections to be cut. If the material is cut where both sections are cut at once, it is better for the cutting action than trying to cut on thin section and then a long length cut for the next section. The longer the
length of cut, the more chance of the cutting disc glazing and motor overload.
NOTE. As the disc wears the cutting capacity will decrease and the depth stop knob may need to be adjusted.
Maintenance
WARNING. Always ensure that the tool is switched off and the plug is removed from the power point before making and adjustments or maintenance procedures.
Power cord maintenance
If the supply cord needs replacing, the task must be carried out by the manufacturer, the manufacturer’s agent, or an authorised service centre in order to avoid a safety hazard.
Cleaning
1.Keep the tool’s air vents unclogged and clean at all times.
2.Remove dust and dirt regularly. Cleaning is best done with a soft brush or a rag.
3.
4.Never use caustic agents to clean plastic parts.
5.Remove the metal that may have built up around the guard and spark deflector.
CAUTION. Do not use cleaning agents to clean the plastic parts of the saw. A mild detergent on a damp cloth is recommended.
General inspection
Regularly check that all the fixing screws are tight. They may vibrate loose over time.
