Operation; Air Source; Lubrication And Maintenance - KNOVA KN 6050 User Manual

OPERATION

1. Regulate pad speed with air regulator
knob.
2. Start the sander off the sanding surface.
Set the sander on the surface gently and
evenly and start the work. Let the sander
do the work. The weight of the sander
will provide efficient sanding. Applying
pressure to the sander will only slow
the speed of the pad and reduce sanding
efficiency. This will also overload the motor
and cause premature wear of the tool
and void the warranty.
3. Work the sander back and forth in a
wide, overlapping motion. Lift the sander
off the surface before releasing
the trigger.

AIR SOURCE

Clean air of correct air pressure is recommended for the power supply for this tool.
A maximum of 90 PSI at the tool is recommended for most air tools of this class. Check
specifications section for recommended pressure. (Depending on length of air hose and
other circumstances, air pressure at compressor may need to be increased to 100 PSI to
ensure 90 PSI at the tool.) Water in the air hose and compressor tank contributes to
reduced performance and damage of the air tool. Drain the air tank and filters before each
use and as necessary to keep the air supply dry. Hose length over 25' causes loss in line
pressure. Increase hose I.D. or increase compressor pressure to compensate for the
pressure loss. Use an in-line pressure regulator with gauge if air inlet pressure is critical.
LUBRICATION & MAINTENANCE
Oil tool before each use. 4 to 5 drops of
a good grade Air Tool Oil placed in the air
inlet is sufficient. Use proper air pressure
and CFM rating listed for this tool.
Drain water from hoses and compressor
tank. Water in the air supply line will cause
gumming and loss of power. Clean the air
filter on the supply line and flush the tool
with gum solvent or a 50/50 mix of air tool
oil and kerosene. It may be necessary to
disassemble the tool to properly clean and
re-lubricate.
4. Start with a paper grit coarse enough to
remove high spots and rough areas.
Continue using progressively finer grit
to attain desired finish.
