When starting the tool with a new or replacement
•
wheel, or a new or replacement wire brush installed,
hold the tool in a well protected area and let it run for
one minute. If the wheel has an undetected crack or flaw,
it should burst in less than one minute. If the wire brush has
loose wires, they will be detected. Never start the tool with a
person in line with the wheel. This includes the operator.
To prevent the spindle end from contacting the
•
bottom of the hole of the hubbed wheel, use
accessories that have a threaded hole depth of
at least 21 mm. Failure to use an accessory with the
appropriate thread depth could result in damage to the
hubbed wheel and injury to the operator or persons in
the area.
Avoid bouncing the wheel or giving it rough
•
treatment. If this occurs, stop the tool and inspect the
wheel for cracks or flaws.
•
Always handle and store wheels in a careful manner.
Do not operate this tool for long periods of time.
•
Vibration caused by the operating action of this tool may
cause permanent injury to fingers, hands, and arms. Use
gloves to provide extra cushion, take frequent rest periods,
and limit daily time of use.
Safety goggles or safety glasses with side shields and
•
a full face shield compliant with ANSI Z87.1 MUST be
worn by the operator and others that are within 50'
(15.2 m) of the use of this product.
Air vents often cover moving parts and should be
•
avoided. Loose clothes, jewelry or long hair can be caught
in moving parts.
An extension cord must have adequate wire size
•
(AWG or American Wire Gauge) for safety. The smaller
the gauge number of the wire, the greater the capacity
of the cable, that is, 16 gauge has more capacity than
18 gauge. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating. When
using more than one extension to make up the total length,
be sure each individual extension contains at least the
minimum wire size. The following table shows the correct
size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The
lower the gauge number, the heavier the cord.

Be sure your power supply agrees with the nameplate
marking. Voltage decrease of more than 10% will cause loss
of power and overheating. These tools are factory tested; if
this tool does not operate, check power supply.
ASSEMBLY AND ADJUSTMENTS
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.
Attaching the Side Handle (Fig. B)
WARNING:This handle SHOULD BE USED AT ALL
TIMES to maintain complete control of the tool.
Always make sure the handle is tight.
Tightly screw side handle
of the gearbox.
Rotating the Gear Case (Fig. C)
To improve user comfort, the gear case will rotate 90 ° for
cutting operations.
1. Remove the four corner screws attaching the gear case
to motor housing.
2. Without separating the gear case from motor housing,
rotate the gear case head to desired position.
nOTE: If the gear case and motor housing become separated
by more than 1/8" (3.17 mm), the tool must be serviced and
14
reassembled by a D
12
tool serviced may lead to motor and bearing failure.

3. Reinstall screws to attach the gear case to the motor
housing. Tighten screws to 12.5 in.-lbs. torque.
Overtightening could cause screws to strip.
