Grizzly H8253 - Manual (Page 6)

Model H8253 Air Belt Sander -4 -
The Model H8253 is designed to be
operated between 70-90 PSI using clean,
dry, regulated, compressed air.
DO NOT
exceed the 90 PSI maximum operating
pressure for your sander.
Before using your new sander, regulate
the air pressure to find the optimum setting
within the specified operating range. Start
by testing the sander at a low setting, then
increase the air pressure as needed for
satisfactory results.
An in-line filter/lubricator/regulator unit can
be installed, as depicted in
Figure 2.
This filter/lubricator/regulator will protect
your tool from damaging water build-up,
allow you to adjust and maintain constant
air pressure to your tool, and save you
the inconvenience of having to manually
lubricate your tool every time you use it.
Compressed Air
System
Avoid overlubricating, as excess oil may
spray out during sanding, potentially
damaging the workpiece and sanding
belt.
Check the current Grizzly catalog for
availability of filters and regulators. If you
plan on installing a filter and regulator in
your compressed air system, always follow
the connection instructions that come with
those units.
Exceeding the maximum permissible
operating pressure may damage the
sander and cause it to malfunction. To
protect yourself from personal injury,
DO NOT allow the air pressure to
exceed the recommended pressure
for this sander!
