rated accessory speed may fly apart and cause injury.
Threaded accessories must have a 5/8"‑11 hub. Every
unthreaded accessory must have a 7/8" (22 mm) arbor
hole. If it does not, it may have been designed for a
circular saw and should not be used. Use only the
accessories shown in the Accessories Chart of this
manual. Accessory ratings must always be above tool
speed as shown on tool nameplate.
• Make sure the 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, hold the tool in a well‑protected area, 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.

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.

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

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.

CAUTION: Always use the correct guard per the
instructions in this manual.
nOTE: If the wheel spins after the clamp nut is tightened,
check the orientation of the threaded clamp nut. If a thin
wheel is installed with the pilot on the clamp nut against the
wheel, it will spin because the height of the pilot prevents
the clamp nut from holding the wheel.
To perform work on the surface of a workpiece:
1. Allow the tool to reach full speed before touching the
tool to the work surface.
, as
2. Apply minimum pressure to the work surface, allowing
the tool to operate at high speed. Material removal rate is
greatest when the tool operates at high speed.
3. Maintain an appropriate angle between the tool
and work surface. Refer to the chart according to
particular function.
