To begin using the tool:
1.
As a standard practice, drain water from the air compressor
tank and air lines prior to use each day (reference your
compressor operators manual for detailed instructions).
2.
Install a 1/4” NPT male connector (not included) into the air
inlet port on the tool (see Figure 2).
Note: Use Teflon® Tape
on all threaded connections.
3.
Turn on the air compressor and allow it to build up pressure.
4.
Adjust the air compressor’s regulator or the supply line
regulator to 90 PSI.
Always make sure the tool is disconnected from any air supply before changing the
grinding stones or accessories, or serious injury could occur.
Grinders will attain extremely high R.P.M. or free speed. Use only accessories that are
rated with R.P.M. equal to or greater than the no-load free speed of your tool.
Inspect each grinding stone for cracks or chips prior to mounting. DO NOT use a
grinding stone that is chipped, cracked or damaged in any other way.
5.
Select the desired grinding stone or accessory.
NOTE: This tool is
equipped with a 1/4” collet chuck, which uses grinding stones and
accessories with a 1/4” spindle.
To change the grinding stones or accessories:
a.
Loosen the collet chuck with the collet wrenches
(included with your tool) by placing one collet wrench on
the flats of the grinder shaft to hold it from turning. Place
the other collet wrench on the flats of the collet chuck
and turn counter-clockwise to loosen (see figure 3).
b.
Insert a grinding stone or accessory into the collet
chuck, then turn the collet chuck clockwise to tighten
using the collet wrenches.
Make sure the grinding stone or accessory spindle is
fully inserted into the collet chuck opening and the
collet chuck is securely tightened. Loose attachments
could fly off during operation and cause serious injury.
c.
After mounting a grinding stone or accessory, hold the
grinder under a workbench and run it for at least 60
seconds to be sure the grinding accessory is secure.
Make sure no one (including the operator) is in the operating plane of the grinding
accessory.
To change the collet chuck:
a.
Loosen the collet chuck with the collet wrenches (included with your tool) by placing one
collet wrench on the flats of the grinder shaft to hold it from turning. Place the other collet
wrench on the flats of the collet chuck and turn counter-clockwise to loosen (see figure 3).
Remove the collet chuck from the tool.
