Health & Safety

Diamond Blade Safety Guidelines

• DO - Insure the arrow on the blade coincides with the direction of rotation of the machine
• DO - Use personal safety equipment (Goggles, Gloves, Face, Head & Noise protection)
• DO - Use the machine guard
• DO - Insure the material is held securely before blade contact
• DO - Guide the blade straight into the material without tilting
• DO - Carry out a slight pendulum movement (forwards, backwards). This maximizes the true potential of blade speed and disperses heat build-up
• DO - Work without too much pressure - the weight of the machine should be sufficient
• DO NOT - Make long continuous cuts with a dry blade (carry out a slight pendulum movement to keep the blade cool)
• DO NOT - Cut to deep in a single pass with a dry blade
• DO NOT - Apply too much pressure and force your diamond blade through the cut
• DO NOT - Let excessive heat be generated at the cutting edge of the blade
• DO NOT - Attempt to cut curves with your blade
• DO NOT - Use standard cutting blades for grinding or for raking out mortar joints

Dry Diamond Core Drilling Guidelines

1. Pilot drill the wall first with a 13mm (1/2") masonry drill.
2. Locate the 12mm 'A' taper guide rod down through the core and 'push fit' the rod into the 'A' taper adaptor. Drill the pilot hole.
3. Use an 850-watt (min) rotary drill fitted with clutch and variable speed control.
4. Don't use hammer action when drilling with a dry diamond core drill.
5. Use machine at between 380-3000 rpm. The harder the material and larger the diameter of core, the slower the rpm. The softer the material and for smaller diameter cores, the higher the rpm. Ultimately, faster rotational speeds does not always mean better penetration.
6. Make sure the chuck is tight.
7. Clear swarf at regular intervals, as a build up will cause over heating, extensive clutch wear and a possible loss of segment.
8. Rotate core bit when entering and leaving hole.
9. Keep machine level.
10. Don't force the bit let it do the work. This will prolong its life and reduce the chance of failure.
11. If the bit starts to vibrate, reduce pressure.
