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! 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.
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.
Allow the tool to stop rotating before laying it down.
Precautions to take when sanding paint
• Sanding of lead based paint is NOT RECOMMENDED
due to the difficulty of controlling the contaminated dust.
The greatest danger of lead poisoning is to children and
pregnant women.
• Since it is difficult to identify whether or not a paint
contains lead without a chemical analysis, we recommend
the following precautions when sanding any paint.
General information
Helpful Hints
• Hold your angle grinder with one hand on the body and
the other hand firmly around the side handle as shown in
Fig. J.
• Always position the guard so that as much of the exposed
disc as possible is pointing away from you. ff Be prepared
for a stream of sparks when the disc touches the metal.
• Maintain an angle between the disc and work surface (Fig.
J) of approximately 30° when grinding and 10°- 15° when
sanding (Fig. K) for best tool control, material removal,
and minimal loading.
CAUTION! Use extra care when grinding into a corner as a
sudden, sharp movement of the grinder may be experienced
when the wheel contacts a secondary surface.
WARNING! Always wear eye protection while
operating this power tool.
MAINTENANCE
Your STANLEY tool has been designed to operate over a long
period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and
regular cleaning.
WARNING! To minimize the danger of serious
personal injury, please switch off the tool power
and disconnect all plugs before adjusting or
removing/ installing any accessory. Before
reassembling the tool, press and release the trigger
switch to make sure the tool is already switched off.
WARNING! Before performing any maintenance on
corded/ cordless power tools:
Lubrication
STANLEY tools are properly lubricated at the
factory and are ready for use.
Tools should be lubricated regularly every year depending on
usage. (Tools used on heavy duty jobs and tools exposed to
heat may require more frequent lubrication.) This lubrication
should be attempted only by trained power tool repairperson’s
such as those at STANLEY service centers or in other
qualified service personnel.
