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 smaller the gauge number, the heavier the cord.

WARNING: Never modify the power tool or any part of it.
Damage or personal injury could result.

WARNING: ALWAYS use safety glasses. Everyday
eyeglasses are NOT safety glasses. Also use face or dust
mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED
SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.

WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains
chemicals known to the State of California to cause cancer,
birth defects or other reproductive harm. Some examples of
these chemicals are:
• lead from lead‑based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically‑treated lumber.
Your risk from these exposures varies, depending on how
often you do this type of work. To reduce your exposure to
these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are
specially designed to filter out microscopic particles.
• Avoid prolonged contact with dust from power
sanding, sawing, grinding, drilling, and other
construction activities. Wear protective clothing and
wash exposed areas with soap and water. Allowing dust
to get into your mouth, eyes, or lay on the skin may promote
absorption of harmful chemicals.

WARNING: Use of this tool can generate and/or disperse
dust, which may cause serious and permanent respiratory or
other injury. Always use NIOSH/OSHA approved respiratory
protection appropriate for the dust exposure. Direct particles
away from face and body.

WARNING: Always wear proper personal hearing
protection that conforms to ANSI S12.6 (S3.19) during
use. Under some conditions and duration of use, noise from
this product may contribute to hearing loss.

Be sure your power supply agrees with the nameplate
marking. Voltage decrease of more than 10% will cause loss
of power and overheating. D
if this tool does not operate, check power supply.
ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of injury, turn unit off
and disconnect it from power source before installing
and removing accessories, before adjusting or when
making repairs. An accidental start‑up can cause injury.
Attaching Side Handle (Fig. B)
The side handle
case in the threaded holes, as shown. Before using the tool,
check that the handle is tightened se cure ly. Use a wrench to
firmly tighten the side handle.
Rotating the Gear Case (Fig. C)
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 re-assembled by a D
Failure to have the tool serviced may cause brush, motor
and bearing failure.
3. Reinstall screws to attach the gear case to the motor
housing. Tighten screws to 18 in.-lbs. (2.03 Nm) torque.
Overtightening could cause screws to strip.
Accessories and Attachments
It is important to choose the correct guards, backing
pads and flanges to use with grinder accessories. Refer to
the Accessories Chart for information on choosing the
correct accessories.

WARNING: Accessories must be rated for at least the
speed recom mended on the tool warning label. Wheels and
other accessories running over rated accessory speed may
burst and cause injury. Threaded accessories must have a
5/8"–11 hub. Every unthreaded accessory must have a 7/8"
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 be above listed minimum wheel speed as shown
on tool nameplate.
