•
whenever a Grinder is issued for use, check free
speed of Grinder with a tachometer to make
certain its actual speed at 90 psig (6.2 bar/620

accessory having a maximum operating speed less
than the free speed of the Grinder in which it is
being used. Always conform to maximum rpm on
grinding wheel blotters.

prior to mounting. Do not use a wheel that is
chipped or cracked or otherwise damaged. Do not
use a wheel that has been soaked in water or any
other liquid.
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

work slowly until the wheel gradually warms up.
Make smooth contact with the work and avoid any
bumping action or excessive pressure.
Model 307A Die Grinder has a free speed of
•
27,000 rpm when operated at 90 psig (6.2 bar/
620 kPa) air pressure. Operation at higher air
pressure will result in excessive speed.
Always match collet size with accessory shank size.
•
Always insert tool shank no less than 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).
