Avoid awkward hand positions where a
sudden slip could cause a hand to move into
the sanding belt or disc.
14. When sanding a large workpiece, provide
additional support at table height.
15. Never force the work. Slowing or stalling the
motor will cause overheating.

stream of water on the work piece. Dip the
workpiece in water to cool it.
17. Do not sand or polish magnesium. It could
catch fire.
18. Always remove scrap pieces and other objects
from the belt and disc tables before turning on
the machine.
19. Never perform layout, assembly or set-up work
on the tables while the sander is operating.
20. Always turn the machine OFF and disconnect
the cord from the power source before
installing or removing accessories.

power is ON or before the machine has come
to a complete stop.
