Tips on SANDING
○ How to place the sandpaper
Lightly press the tool to the surface to be processed;
making sure that the sandpaper is evenly applied to
the surface. Applying unnecessary pressure will place
stress on the motor and shorten the sandpaper's life,
reducing polishing effi ciency.
○ How to move the tool
Using your hand, repeatedly push out and pull back in
a back and forth motion.
○ New coarse sandpaper with rougher grit
New coarse sandpaper with rougher grit may cause
the unit to jerk. During the start of the task, slightly
tilt the unit towards the front or back for a while,
maintaining the tilted position. The jerking will stop as
the sandpaper adapts to the task.
○ Until the surface being processed is polished
Use the same grade of sandpaper until the surface
being processed is evenly polished. Switching to
a diff erent grade of sandpaper when the task is not
completed may result in an uneven fi nish.
○ Testing
Before starting a task, it is recommended that you
check the vibration frequency using excess material.
