USED ONLY WHEN ATTACHING AND REMOVING THE
PAD.
Let the sander do the work. The normal weight of the
sander is sufficient for sanding. Do not put additional
pressure on the sander. This will only slow down the
speed of the pad, reduce sanding efficiency and put an
additional burden on the motor. Start the sander off the
work surface, set it down on the work surface evenly and
move it slowly back and forth in wide, overlapping areas.
When finished sanding, lift it off the work surface before
stopping
motor.
Start the work with an abrasive grit just coarse enough to
remove high spots and roughness.
Follow with additional
sanding using finer grits until the desired finish is
obtained. Never go from a coarse grit to a fine grit in one
step. It may be difficult to remove swirl marks made by
coarse abrasives.
Use the finest grits practical for
roughing operations
and finish by using successively
finer grits.
Before the toot is connected to the air supply, clear the air
hose of accumulated
dust and moisture and add 1/4 oz.
of air tool oil.
Lubrication
An in-line filter-regulator-lubricator
(fig 1) is recommended
as it increases toot life and keeps the toot in sustained
operation. The in-line lubricator should be regularly
checked and filled with air toot oil. Proper adjustment of
the in-line lubricator is performed by placing a sheet of
paper next to the tools exhaust ports and holding the
throttle open approximately 30 seconds. The lubricator is
properly set when a light stain of oil collects on the paper.
Excessive amounts of oil should be avoided.
In the event that it becomes necessary to store the tool for
an extended period of time (overnight, weekend, etc.), it
should receive a generous amount of lubrication through
the air inlet. The tool should be run for approximately 30
seconds to ensure oil has been evenly distributed
throughout the toot. The tool should be stored in a clean
and dry environment.
Recommended
lubricants:
Use air tool oil or any other
high grade turbine oil containing moisture absorbent, rust
inhibitors, metal wetting agents and an EP (extreme
pressure) additive.
