the air tool after lubrication.
Tips
•Beginsandingwithanabrasivegritsandpapercoarse
enough to remove the high spots. Progress to a finer grit
sandpaper until the desired finish is obtained.
•Neverchangefromcoarsegritsandpapertoaveryfinegrit
sandpaper, always progress gradually to the finer grit.
OPERATING INSTRUCTIONS
•Selectasuitableabrasivediscandmakesurethatitisfixed
securely to the tool.
•Connecttosuitableairsupplyasrecommended.
•Applythesanderlightlytotheworkandallowtheabrasive
disc to cut. Take great care when sanding around sharp
edges and surfaces to avoid the disc snagging i.e. the disc
may be brought to an abrupt stop or considerably slowed,
causing the tool to kick in the hands.
NOTE:
Use of safety glasses and a breathing mask is
recommended. Sanding certain materials may create
hazardous dust which may require special breathing
equipment. Check before using the tool. Although the tool has
a low noise level, the actual sanding process may cause a
noise level such that ear protectors will be required. Safety
gloves are recommended.
Do not continue to use abrasive discs that are worn or clogged.
Do not use undersized or oversized sanding discs. The disc
should be no more than 1/4” larger in diameter than the pad,
and not smaller than the pad.
MAINTENANCE
Lubrication
Air tools require lubrication throughout the lifetime of the tools.
The air motor and bearing uses compressed air to power the tool.
The compressed air contains moisture that will rust the air motor
and other parts in side of the tools, therefore lubrication is required
daily. Failure to lubricate the air tool properly will dramatically
shorten the life of the tool and will void the warranty
CAUTION: This air tool requires lubrication BEFORE initial use,
also before and after each additional use.
