f Apply slight pressure to the tool. Do not apply side
pressure to the abrasive disc.
f Avoid overloading. If the tool becomes hot, let it spin
for a few minutes with no load.
1. 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 work piece.
2. Keep the edge of the wheel tilted at angle from 15 to
30 degrees against the surface of the work piece.
3. When using a new grinding wheel, do not operate
the wheel in the B direction, otherwise, it will cut into
the work piece. 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
(Fig. A), with the other hand on the body of the tool, as
shown in Fig. 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 before 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 work pieces. 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! Metal powder accumulates. 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.
