spindle lock only when the tool is turned off, unplugged
from the power supply, and has come to a completestop.
NOTICE: To reduce the risk of damage to the tool, do
not engage the spindle lock while the tool is operating.

CAUTION: Hold the side handle and 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.C)

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 ON/OFF slider switch

OPERATION

WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start-up can causeinjury.
Prior to Operation
• Install the guard and appropriate disc or wheel. Do not
use excessively worn discs orwheels.
• Be sure the threaded locking flange is mounted correctly.
Follow the instructions given in the Grinding and
Cutting AccessoryChart.
• Make sure the disc or wheel rotates in the direction of the
arrows on the accessory and thetool.
• Do not use a damaged accessory. Before each use,
inspect the accessory such as abrasive wheels for chips
and cracks, backing pad for cracks, tear or excess wear,
wire brush for loose or cracked wires. If power tool or
accessory is dropped, inspect for damage or install an
undamaged accessory. After inspecting and installing
an accessory, position yourself and bystanders away
from the plane of the rotating accessory and run the
power tool at maximum no‑load speed for one minute.
Damaged accessories will normally break apart during
this testtime.

WARNING:
• Ensure all materials to be ground or cut are secured
inplace.
• Secure and support the workpiece. Use clamps or a
vise to hold and support the workpiece to a stable
platform. It is important to clamp and support the
workpiece securely to prevent movement of the
workpiece and loss of control. Movement of the
workpiece or loss of control may create a hazard
and cause personalinjury.
• Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under
their own weight. Supports must be placed under
the workpiece near the line of cut and near the
edge of the workpiece on both sides of thewheel.
• Always wear regular working gloves while
operating thistool.
• The gear becomes very hot duringuse.
• Apply only a gentle pressure to the tool. Do not
exert side pressure on thedisc.
• Avoid overloading. Should the tool become hot,
let it run a few minutes under no load condition
to cool the accessory. Do not touch accessories
before they have cooled. The discs become very hot
duringuse.
• Never work with the grinding cup without a
suitable protection guard inplace.
• Do not use the power tool with a cut-offstand.
• Never use blotters together with bonded
abrasiveproducts.
