cracked or otherwise damaged. Do not use a wheel
that has been soaked in water or any other liquid.
Make certain the grinding wheel properly fits the
arbor. The wheel should not fit too snugly or too
loosely. Plain hole wheels should have about 0.007"
(0.17 mm) maximum diametral clearance. Do not use
reducing bushings to adapt a wheel to any arbor
unless such bushings are supplied by or recommended
by the wheel manufacturer.
After mounting a new wheel, hold the Grinder
under a steel workbench or inside a casting and run it
for at least 60 seconds. Make certain no one is
within the operating plane of the grinding wheel. If
a wheel is defective, improperly mounted or the
wrong size and speed, this is the time it will usually
fail.
When starting with a cold wheel, apply it to the
work slowly until the wheel gradually warms up.
Make smooth contact with the work and avoid
any bumping action or excessive pressure.
Always replace a damaged, bent or severely worn
wheel guard. Do not use a wheel guard that has
been subjected to a wheel failure.
Make certain wheel flanges are at least 1/3 the
diameter of grinding wheel, free of nicks, burrs and
sharp edges. Always use wheel flanges furnished by
the manufacturer; never use a makeshift flange or a
plain washer. Tighten Flange Nut securely.
Guard opening must face away from operator.
Bottom of wheel must not project beyond guard.
Always match collet size with accessory shank size.
Always insert tool shank no less than 3.8I (10 mm) in
the collet. Tighten Collet Nut securely to prevent
accessory from working out during operation of the
Grinder. Check tightness of Collet Nut before
operating the Grinder. Pay particular attention to
the fact that allowed speed of a mounted point is
lowered when the length of the shaft is increased
between end of collet and mounted point (overhang).
Series 325SC and XC Grinders have a free speed of
25 000 rpm; Series 330SC and XC Grinders have a
free speed of 30 000 rpm; Series 335SC Grinders have
a free speed of 35 000 rpm, when operated at 90 psig
(6.2 bar/620 kPa) air pressure. Operation at higher air
pressure will result in excessive speed.
WARNING
Always wear hearing
protection when operating
this tool.
