Maintenance
LUBRICATION:
An automatic in-line filter-regulator-lubricator is recommended as it increases tool life
and keeps the tool in sustained operation. The in-line lubricator should be regularly
checked and filled with air tool oil. Proper adjustment of the in-line lubricator is
performed by placing a sheet of paper next to the 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 at that
time. The tool should be run for approximately 30 seconds to ensure oil has been
evenly distributed throughout the tool. The tool should be stored in a clean and dry
environment.
Recommended lubricants: Use John Deere AT-4003 air tool oil or any other high
grade turbine oil containing moisture absorbent, rust inhibitors, metal wetting agents
and an EP (extreme pressure) additive.
Operation
PRE-OPERATION:
Before the tool is connected to the air supply, clear the air hose of accumulated dust
and moisture. Before removing a tool for service or changing accessories, make sure
the air line is shut-off and drained of air. This will prevent the tool from operating if the
throttle is accidentally engaged.
OPERATION:
This tool is designed to use pressure sensitive adhesive (PSA) sanding paper. Trim
sanding paper to match size of pad assembly and apply to pad per manufacturers
instructions.
Let the sander do the work. Do not put excessive pressure on the tool. 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, set it down on the work evenly and
move it back and forth in wide, overlapping areas. When finished sanding, lift the
sander off the work before stopping motor.
Start the work with an abrasive grit just coarse enough to remove high spots and
roughness. Follow by 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.
Use the finest grits practical for roughing operations and finish by using progressively
finer grits.
