WARNING
GRINDER SPECIFIC WARNINGS
FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY.
•
Do not use this tool if actual free speed exceeds the
nameplate rpm.
•
Before mounting a wheel, and after any tool repair
check free speed of Grinder with a tachometer to
make certain its actual speed at 90psig (6.2
bar/620kPa) does not exceed rpm stamped or
printed on the nameplate.
•
Do not use any grinding wheel, burr or other
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.
•
Do not use cutting--off wheels and routing cutter
wheels with this tool.
•
Inspect all grinding wheels for chips or cracks
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 60seconds. 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.
•
Model PF40 0 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 10mm 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. 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).
