OPERATION
Select a suitable abrasive disc and make sure that it is fixed
securely to the pad. Connect a suitable air supply as recommended
in Figure 1, on page 4. The air inlet on this tool has a standard ¼”
NPT thread.
After mounting sandpaper, start this Sander under a bench in
order to make sure sandpaper is firmly attached. Set the sander
down on the work evenly and move it slowly back & forth in wide,
overlapping areas. Additional pressure may be used to make
more efficient use of the tool when material to be sanded is thick.
Lighter pressure may be used in delicate sanding or when using
edges of sanding pad. When finished sanding, lift it off the work
before stopping the motor.
Take great care when sanding around sharp edges and surfaces
to avoid disc snagging, i.e. the disc may be brought to an abrupt
stop or considerably slowed which will cause the tool to kick in
the operator’s hands. It is always recommended to use safety
gloves and safety glasses. The sanding of certain materials may
create a hazardous dust which may require special breathing
equipment. Check before using the tool. It is recommended to use
proper breathing equipment while sanding. Even if the tool has a
low noise level, the actual sanding process may cause a noise
level such that ear protection should be used. It is recommended
that ear protection be used while sanding.
Do not continue to use abrasive discs that are worn or clogged.
This will make the sanding process inefficient and increases
the need to apply unnecessarily high forces to the tool. Do not
use oversized or undersized sanding discs. The disc should be
no more than ¼” larger in diameter than the pad and never be
smaller than the pad size.
An air regulator is located on the bottom of the tool housing.
It can be used to vary the volume of compressed air fed to the
motor which will vary the speed of the sander.
Always turn off the air supply, drain hose of air pressure and
detach tool from air supply before installing, removing or
adjusting any part or accessory on this tool, or before performing
any maintenance on this tool.
NOTE: During operation, safety goggles must always be worn to
guard against flying debris (users and bystanders).
