Facts About Abrasive Wheel
ECHO wheels are made by laying a strong fibre mesh material into a form,
pouring a mixture of resin and the abrasive grit particles over the mesh,
and adding a second layer of mesh over the mixture. Then the resin and
reinforcing mesh are bonded together and cured.
The wheel’s ability to cut certain materials are due to the type abrasive, size
of the grit and it’s spacing. The reinforcement on both sides adds strength
and rigidity.
Always read the label on the wheel. If the wheel does not cut well, it may be
the wrong type for the material. Forcing it to cut may result in shattering of
the wheel and serious injury to the operator.
WARNING
Do not use water with an abrasive wheel.
Do not grind with a cut-off wheel or put pressure on the sides.
Use only ECHO reinforced wheels, or wheels approved for this saw
by ECHO.
Wheels that are too thick or fit the arbour improperly may shatter,
causing serious personal injury. So may wheels of low speed rating
or those that are cracked, warped, out-of-round or edge-damaged.
A wheel can stand a lot of cutting pressure as long as the pressure is straight
on and not from the side of the wheel. This is why you always must make
only straight line cuts.
Saws intended for forcible entry should be equipped with new wheels for
each use. If the used wheels can pass the ring test (page 13) and close
inspection, they may be use in training emergency crews.
Check every wheel for warping, cracks and broken edges before mounting
on the saw.
Warped wheels do not cut properly and may be stressed to the point of
breaking. Always store your wheels laying flat, on a dry surface. When
stacking many wheels, place cardboard or paper spacers between them as a
cushion.
Moisture and heat both can cause wheel damage. Do not let wheels lie in the
sun or expose them to high heat. Keep wheels dry at all times, and store in
an area of low humidity and moderate temperature. Protection from moisture
damage applies during water-flush cutting.
