Keep in mind the diamond edge of
the blade is not the part that wears away ... it's the BACKING (the
brassy part of the blade) that wears as you cut. Here are some helpful hints
to get the longest life from your blade:
- Push lightly when sawing. Let
the saw do the work. Pushing too hard will cause excess wear and
will make the pattern harder to follow. Light pressure will minimize
blade twisting. When the blade twists, it wears the backing down.
- When you find it necessary to
back your blade out of a cut, TURN THE SAW OFF and use your thumb to
hold the blade in place against the guide blocks.
blade out with the saw running will cause excessive wear on the
blade back and will enlarge the hole in your work surface. Once your
glass has been backed out, be sure the blade is properly set into
the upper and lower guide blocks before turning the saw back on.
- The tighter the curve you are
cutting, the harder the blade back will scrape against the edge of
the glass you've just gone through. When cutting tight curves,
reduce your pushing pressure to next to nothing and just steer the
blade along your pattern line. The saw kerf (the kerf is the narrow
gap created by the blade) will widen slightly, reducing the wear and
tear on the blade backing.
- Keep your blade tension
adjusted! If the blade wants to skip out of the lower guide block,
turn the adjusting knob (located between the two upright posts at
the left end of the work surface) counterclockwise 1/8 turn. If the
blade skips out of the top AND bottom guide blocks, then you need to
LOOSEN the tension by turning 1/8 turn clockwise.
- Keep your blade guides in
shape! When you notice the blade guides are wearing down, replace
them! It's lots cheaper spend a couple bucks on a set of blade
guides than $49 for a new blade!
