Stanley FATMAX FMC761 Original Instructions Manual page 11

Apply minimum pressure to the work surface, allowing the
u
tool to operate at high speed. Grinding rate is greatest
when the tool operates at high speed.
Maintain a 20˚ to 30˚ angle between the tool and work
u
surface.
Continuously move the tool in a forward and back motion
u
to avoid creating gouges in the work surface.
Remove the tool from work surface before turning tool off.
u
Allow the tool to stop rotating before laying it down.
Edge grinding with grinding wheels
Wheels used for cutting and edge grinding may break or
kick back if they bend or twist while the tool is being used
to do cut-off work or deep grinding. To reduce the risk of
serious injury, limit the use of these wheels with a standard
Type 27 guard to shallow cutting and notching (less than 1/2
inch (13mm) in depth). The open side of the guard must be
positioned away from the operator. For deeper cutting with
a Type 1 cut-off wheel, use a closed Type 1 guard. See the
Grinding and cutting chart which can be found at the back of
language section.
Allow the tool to reach full speed before touching the tool
u
to the work surface.
Apply minimum pressure to the work surface, allowing the
u
tool to operate at high speed. Grinding rate is greatest
when the tool operates at high speed.
Position yourself so that the open-underside of the wheel
u
is facing away from you.
Once a cut is begun and a notch is established in the
u
workpiece, do not change the angle of the cut. Changing
the angle will cause the wheel to bend and may cause
wheel breakage. Edge grinding wheels are not designed
to withstand side pressures caused by bending.
Remove the tool from the work surface before turning
u
the tool off. Allow the tool to stop rotating before laying it
down.
Do not use edge grinding/cutting wheels for surface grinding
applications because these wheels are not designed for side
pressures encountered with surface grinding. Wheel breakage
and injury may result.
Surface finishing with sanding flap discs
Allow the tool to reach full speed before touching the tool
u
to the work surface.
Apply minimum pressure to work surface, allowing the tool
u
to operate at high speed. Sanding rate is greatest when
the tool operates at high speed.
Maintain a 5˚ to 10˚ angle between the tool and work
u
surface.
Continuously move the tool in a forward and back motion
u
to avoid creating gouges in the work surface.
Remove the tool from work surface before turning tool off.
u
Allow the tool to stop rotating before laying it down.
(Original instructions)
Using sanding backing pads
Choose the proper grit sanding discs for your application.
Sanding discs are 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
u
Medium 36 - 80 grit
u
Fine Finishing 100 - 120 grit
u
Very Fine Finishing 150 - 180 grit
u
Allow the tool to reach full speed before touching tool to
u
the work surface.
Apply minimum pressure to work surface, allowing the tool
u
to operate at high speed. Sanding rate is greatest when
the tool operates at high speed.
Maintain a 5˚ to 15˚ angle between the tool and work
u
surface. The sanding disc should contact approximately
one inch (25mm) of work surface.
Move the tool constantly in a straight line to prevent burn-
u
ing 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.
Remove the tool from work surface before turning tool off.
u
Allow the tool to stop rotating before laying it down.
Using wire cup brushes and wire wheels
Wire wheels and brushes can be used for removing rust, scale
and paint, and for smoothing irregular surfaces.
Note: The same precautions should be taken when wire
brushng paint as when sanding paint.
Allow the tool to reach full speed before touching the tool
u
to the work surface.
Apply minimum pressure to work surface, allowing the tool
u
to operate at high speed. Material removal rate is greatest
when the tool operates at high speed.
Maintain a 5˚ to 10˚ angle between the tool and work
u
surface for wire cup brushes.
Maintain contact between the edge of the wheel and the
u
work surface with wire wheels.
Continuously move the tool in a forward and back motion
u
to avoid creating gouges in the 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.
Remove the tool from the work surface before turning
u
the tool off. Allow the tool to stop rotating before setting it
down.
Use extra care when working over an edge, as a sudden
sharp movement of grinder may be experienced.
