3.5 Blade Sharpness
It is essential that the blade be sharp at all times, if the machine is to
operate properly. Although not all conditions are the same it has
been found that blades require sharpening after approximately 100
resurfacings.
Your OLYMPIA 500 ice resurfacer is equipped with a hardened high-
quality alloy steel blade which is 58 to 62 Rockwell hard. When you
are purchasing replacement blades, other than from us, beware of
poor-quality blades, e.g. SOFT METALS.
NOTE: You should beware of poor-quality sharpening services, e.g.
The burrs from grinding must be honed off.
3.6 Blade Sharpening
STRAIGHT – The blade should be sharpened so that it is straight.
To check to make sure your blades are being sharpened straight,
just lay two sharpened blades on a flat surface with the sharpened
ends of the blades, sharpened edge to sharpened edge. Then make
sure that the edges are touching for the full length of the blades.
ANGLE – When you get your blades sharpened, the blades should
be ground at a 27-degree angle and should be ground with one
bevel. If your blades are not at the correct angle – too high, the result
may be a chattering effect, while if the angle is too low the blade will
not shave the ice.
