• The gear becomes very hot during use.
• Apply only a gentle pressure to the tool. Do not exert side
pressure on the disc.
• Always install the guard and appropriate disc or wheel. Do not
use excessively worn disc or wheel.
• 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.
• Be aware, the wheel continues to rotate after the tool is
switched off.
Proper Hand Position (Fig. G)
WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.
WARNING: To reduce the risk of serious personal injury,
ALWAYS hold securely in anticipation of a sudden reaction.
Proper hand position requires one hand on the side handle
with the other hand on the body of the tool, as shown in Fig. G.
Paddle Switch (Fig. A)
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.
1. To turn the tool on, push the lock-off lever
back of the tool, then depress the paddle switch
run while the switch is depressed.
2. Turn the tool off by releasing the paddle switch.

from rotating when installing or removing wheels. Operate the
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. Damage to the tool
will result and attached accessory may spin off possibly resulting
in injury.
To engage the lock, depress the spindle lock button and rotate
the spindle until you are unable to rotate the spindle further.
Surface Grinding, Sanding and Wire Brushing
CAUTION: Always use the correct guard per the
instructions in this manual.
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.
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.

4. Maintain contact between the edge of the wheel and the
work surface.
- If grinding, sanding with flap discs or wire brushing move
the tool continuously in a forward and back motion to avoid
creating gouges in the work surface.
- If sanding with a backing pad, move the tool constantly in a
straight line to prevent burning and swirling of work surface.

nOTE: Allowing the tool to rest on the work surface without
moving will damage the work piece.
5. Remove the tool from work surface before turning tool off.
Allow the tool to stop rotating before laying it down.
CAUTION: Use extra care when working over an edge, as a
sudden sharp movement of grinder may be experienced.
Precautions To Take When Working on a Painted
Workpiece
1. Sanding or wire brushing 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.
2. 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:
Personal safety
1. No children or pregnant women should enter the work area
where the paint sanding or wire brushing is being done until all
clean up is completed.
2. A dust mask or respirator should be worn by all persons
entering the work area. The filter should be replaced daily or
whenever the wearer has difficulty breathing.
nOTE: Only those dust masks suitable for working with lead
paint dust and fumes should be used. Ordinary painting masks
do not offer this protection. See your local hardware dealer for
the proper N.I.O.S.H. approved mask.
3. NO EATING, DRINKING or SMOKING should be done in the
work area to prevent ingesting contaminated paint particles.
Workers should wash and clean up BEFORE eating, drinking or
smoking. Articles of food, drink, or smoking should not be left in
the work area where dust would settle on them.
Environmental safety
1. Paint should be removed in such a manner as to minimize
the amount of dust generated.
2. Areas where paint removal is occurring should be sealed
with plastic sheeting of 4 mils thickness.
3. Sanding should be done in a manner to reduce tracking of
paint dust outside the work area.
