USING SANDING BACKING PADS
Choose the proper grit sandpaper for
your application. Sandpaper is available in various grits. Coarse
grits yield faster material removal rates and a rougher finish.
Finer grits yield slower material removal and a smoother finish.
Begin with coarse grit discs for fast, rough material removal.
Move to a medium grit paper and finish with a fine grit disc for
optimal finish.
Coarse 16 - 30 grit
Medium 36 - 80 grit
Fine Finishing 100 - 120 grit
Very Fine Finishing 150 - 180 grit
1. Allow the tool to reach full speed before touching tool to the
work surface.
2. Apply minimum pressure to work surface, allowing the tool to
operate at high speed. Sanding rate is greatest when the tool
operates at high speed.
3. Maintain a 5˚ to 15˚ angle between
5˚-15˚
the tool and work surface. The
san ding disc should contact
approximately one inch of work
surface.
4. Move the tool constantly in a straight
line to prevent burning and swirling of work surface. Allowing
the tool to rest on the work surface without moving, or moving
the tool in a circular motion causes burning and swirling marks
on the work surface.
5. Remove the tool from work surface before turning tool off.
Allow the tool to stop rotating before laying it down.
Mounting and Using Wire Brushes
and Wire Wheels
Wire cup brushes or wire wheels screw directly on the grinder
spindle without the use of flanges. Use only wire brushes or
wheels provided with a 5/8"-11 threaded hub. A Type 27 guard is
required when using wire brushes and wheels.
CAUTION: Wear work gloves when handling wire brushes
and wheels. They can become sharp.
CAUTION: Wheel or brush must not touch guard when mounted
or while in use. Undetectable damage could occur to the accessory,
causing wires to fragment from accessory wheel or cup.
MOUNTING WIRE BRUSHES AND WIRE WHEELS
WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments
or accessories. Before reconnecting the tool, depress and
release the trigger switch to ensure that the tool is off.
