WARNING!
• Make sure all materials to be grinded are secured in
position.
• Apply slight pressure to the tool. Do not apply side
pressure to the abrasive disc.
• Avoid overloading. If the tool becomes hot, let it spin for
a few minutes with no load.
• Be sure to hold the tool tightly with both hands (one
hand on housing, the other on side handle). Start the
tool and bring the grinding wheel on the workpiece.
• Keep the edge of the wheel tilted at angle from 15 to 30
degrees against the surface of the workpiece.
• When using a new grinding wheel, do not operate the
wheel in the B direction, otherwise, it will cut into the
workpiece. When the edge of wheel has been rounded
off, you are free to operate the grinder in either the A or
B direction.
Starting and stopping (Fig A)
WARNING: Before using the tool, check whether
the handle is tightened securely. Check whether
the ON/OFF switch is working normally.
Before plugging in the tool to the power supply, check
whether the switch is in the OFF (o) position when pressing
the rear end of the switch.
To start the tool, press the rear end of the switch and slide
it forward. Then press the front end of the switch to lock it.
Press the rear end of the switch to stop the tool.
WARNING: Do not switch the tool on or off while
under load conditions.
Proper hand position (Fig F)
WARNING: To reduce the risk of serious personal
injury, ALWAYS use proper hand position as
shown.
WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of
a sudden reaction.
Proper hand position requires one hand on the side handle
(Figure A), with the other hand on the body of the tool, as
shown in Figure F.
Switches
CAUTION! Hold the body of the tool firmly
to maintain control of the tool at start up and
during use and until the wheel or accessory
stops rotating. Make sure the wheel has come
to a complete stop be fore laying the tool down.
NOTE: To reduce unexpected tool movement, do not
switch the tool on or off while under load conditions. Allow
the grinder to run up to full speed before touching the work
surface. Lift the tool from the surface before turning the tool
off. Allow the tool to stop rotating before putting it down.
Slider switch (Fig A)
WARNING: Before connecting the tool to
a power supply, be sure the slider switch is in the
off position by pressing the rear part of the switch
and releasing. Ensure the slider switch is in the off
position as described above after any interruption
in power supply to the tool, such as the activation
of a ground fault interrupter, throwing of a circuit
breaker, accidental unplugging, or power failure.
If the slider switch is locked on when the power is
connected, the tool will start unexpectedly.
To start the tool, slide the slider switch (1) toward the front
of the tool. To stop the tool, release the slider switch. For
continuous operation, slide the switch toward the front of the
tool and press the forward part of the switch inward. To stop
the tool while operating in continuous mode, press the rear
part of the slider switch and release.
Spindle lock (Fig A)
The spindle lock (2) prevents the output shaft from rotating
when attaching or removing the grinding wheel. Only use
the spindle lock when the tool is switched off, power is
unplugged, and wheel stops completely.
Note: To minimize tool damages, don't use the spindle lock
when the tool is operating.
Otherwise, it may damage the tool. The attached
accessories may come off and cause injury.
If using the spindle lock, press the spindle lock button and
rotate the output shaft until it stops.
Application on metals
When applying the tool on metals, make sure that
a residual-current device (RCD) is inserted to prevent
danger from metal chips.
If the RCD causes power disconnection, have the tool sent
to an authorized STANLEY dealer for repair.
WARNING: Under extreme working conditions,
conductive dust and grit may accumulate on the
housing interior when handling metal workpieces.
This could create an electric shock hazard as it weakens the
protective insulation in the grinder.
To avoid accumulation of metal chips in the interior of the
grinder, we recommend cleaning the ventilation ducts daily.
Refer to Maintenance.
Using grinding wheels
WARNING!
Excessive use of the grinding wheel on metals
may increase the risk of electric shock. To reduce
the risk, insert the RCD before use and clean the
ventilation ducts daily. Follow the maintenance
instructions below to blow dry compressed air
into the ventilation ducts.
Grinding
Surface Grinding with Grinding Wheels
1. Allow the tool to reach full speed before touching the
tool to the work surface.
2. Apply minimum pressure to the work surface, allowing
the tool to operate at high speed. Grinding rate is
greatest when the tool operates at high speed.
3. Maintain a 20˚ to 30˚ angle between the tool and work
surface.
4. Continuously move the tool in a forward and back
motion to avoid creating gouges in the work surface.
5. Remove the tool from work surface before turning tool
off.
