they will be reinstalled.
c. If either carbon brush is worn down by
more than 1/2, replace them both.
d. To clean old carbon brushes before
reusing them, rub the contact areas with
a pencil eraser.
e. Reinsert the old carbon brushes in the
same orientation to reduce wear.
f. When installing, make sure the carbon
portions of the brushes contact the
motor armature, and that the springs
face away from the motor. Also, make
sure the springs operate freely.
g. Replace the Carbon Brush Covers.
Do not overtighten.
NOTE
: New carbon brushes tend to spark
when first used until they wear and conform
to the motor’s armature.
WARNING
If the supply cord of this
power tool is damaged, it must be replaced
only by a qualified service technician.
CARE & MAINTENANCE
TROUBLESHOOTING
Problem
Possible Causes
Likely Solutions
Tool will not start.
1. Cord not connected.
2. No power at outlet.
3. Internal damage or wear.
(Carbon brushes or switch,
for example.)
1. Check that cord is plugged
in.
2. Check power at outlet. If
outlet has no power, turn off
tool and check circuit
breaker. If breaker is
tripped, make sure circuit is
right capacity for tool and
circuit has no other loads.
3. Replace Carbon Brushes
and/ or have technician
service tool.
Tool operates slowly.
1. Excess pressure applied to
workpiece.
2. Power being reduced by
long or small diameter
extension cord.
1. Decrease pressure, allow
tool to do the work.
2. Eliminate use of extension
cord. If an extension cord is
needed, use one with the
proper diameter for its
length and load. See
Extension Cords in
GROUNDING section.
Performance
decreases over time.
Carbon brushes worn or
damaged.
Replace brushes.
Excessive noise
or rattling.
Internal damage or wear.
(Carbon brushes or bearings,
for example.)
Have technician service tool.
IMPORTANT SAFETY INFORMATION
at all times. Do not reach over or across running machines,
hoses, cords, etc.
6. Dress properly. Do not wear loose clothing or jewelry. Keep
your hair, clothing, and gloves away from moving parts. Loose
clothes, jewelry or long hair can be caught in moving parts.
7. Work Safe. Operate tool a safe distance from yourself and oth-
ers in the work area. Do not run the power tool while carrying
it at your side. Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory into your body.
Never lay the power tool down until the accessory has come to
a complete stop. The spinning accessory may grab the surface
and pull the power tool out of your control. Keep proper footing
and balance at all times. Do not overreach, especially on
ladders. Be certain ladders being used are sturdy, stable, on a
firm surface and erected as safe working angles. Do not reach
over or across running machines, hoses, cords, etc.
8. Inspect before every use; do not use if parts are loose or
damaged.
9. Do not alter this product in any way.
10. Use the right tool for the job. Do not attempt to force a small
tool or attachment to do the work of a larger industrial tool.
Don’t use a tool whose performance is not adequate for your
work. Do not modify this tool and do not use this tool for a
purpose for which it was not intended.
11. Power tool plugs must match the outlet. Never modify the
plug in any way. Do not use any adapter plugs with earthed
(grounded) power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
12. People with pacemakers should consult their physician(s)
before use. Electromagnetic fields in close proximity to heart
pacemaker could cause pacemaker interference or pace-
maker failure. In addition, people with pacemakers should:
• Avoid operating alone.
• Do not use with power switch locked on.
• Properly maintain and inspect to avoid electrical shock.
• Any power cord must be properly grounded. Ground Fault
Circuit Interrupter (GFCI) should also be implemented – it
prevents sustained electrical shock.
13. Avoid body contact with earthed or grounded surfaces such
as pipes, radiators, ranges and refrigerators. There is an
increased risk of electric shock if your body is earthed or
grounded.
14. Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
15. Do not abuse the cord. Never use the cord for carrying,
pulling or unplugging the power tool. Position the cord clear
of the spinning accessory. If you lose control, the cord may
be cut or snagged and your hand or arm may be pulled
into the spinning accessory. Keep cord away from heat, oil,
sharp edges or moving parts. Damaged or entangled cords
increase the risk of electric shock.
16. When operating a power tool outdoors, use an extension cord
suitable for outdoor use. Use of a cord suitable for outdoor
use reduces the risk of electric shock.
17. If operating a power tool in a damp location is unavoidable,
use a ground fault circuit interrupter (GFCI) protected supply.
Use of a GFCI reduces the risk of electric shock.
18. Use power tool ONLY on adequately rated circuits to avoid
overheating of electrical systems.
19. Prevent accidental starting. Ensure switch is in the “OFF”
position before connecting to power source and/or battery
pack, picking up or carrying the tool. Carrying power tools
with your finger on the switch or energizing power tools that
have the switch “ON” invites accidents.
20. Do not use the power tool if the switch does not turn it on and
off. Any power tool that cannot be controlled with the switch is
dangerous and must be repaired.
21. Have your power tool serviced by a qualified repair person
using only identical replacement parts. This will ensure that
the safety of the power tool is maintained. Follow instructions
in the Maintenance section of this manual. Use of unauthor-
ized parts or failure to follow Maintenance Instructions may
create a risk of shock or injury.
22. Maintain labels and nameplates on the tool. These carry im-
portant safety information. If unreadable or missing, contact
Performance Tool® for a replacement.
23. Disconnect the plug from the power source before making
any adjustments or changing accessories. Such preventive
safety measures reduce the risk of starting the power tool
accidentally.
24. Maintain power tools. Check for misalignment or binding
of moving parts, breakage of parts and any other condition
that may affect the power tool’s operation. Regularly clean
the power tool’s air vents. The motor’s fan will draw the dust
inside the housing and excessive accumulation of powdered
metal may cause electrical hazards. If damaged, have the
power tool repaired before use. Many accidents are caused
by poorly maintained power tools.
25. Use the power tool, accessories and tool bits etc. in accor-
dance with these instructions, taking into account the working
conditions and the work to be performed. Use of the power
tool for operations different from those intended could result
in a hazardous situation.
26. Store idle equipment. When not in use, tools must be stored
in a dry location to inhibit rust. Always lock up tools and keep
out of reach of children and other untrained persons. Switch
off all unused electrical tools when stored. Disconnect battery
from unit. Tools are dangerous in the hands of untrained
users.
27. Operations such as grinding, wire brushing, or cutting-off
are not recommended to be performed with this power tool.
Operations for which the power tool was not designed may
create a hazard and cause personal injury.
28. Do not use accessories which are not specifically designed
and recommended by the tool manufacturer. Just because
the accessory can be attached to your power tool, it does not
assure safe operation.
29. The rated speed of the accessory must be at least equal to
the maximum speed marked on the power tool. Accessories
running faster than their RATED SPEED can break and fly
apart.
30. The outside diameter and the thickness of your accessory
must be within the capacity rating of your power tool. Incor-
rectly sized accessories cannot be adequately guarded or
controlled.
31. The arbor size of wheels, flanges, backing pads or any other
accessory must properly fit the spindle of the power tool.
Accessories with arbor holes that do not match the mounting
hardware of the power tool will run out of balance, vibrate
excessively and may cause loss of control.
32. Do not use excessively oversized sanding disc paper. Follow
manufacturer’s recommendations when selecting sanding
paper. Larger sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause snagging,
tearing of the disc or kickback.
33. Do not allow any loose portion of the polishing bonnet or its
attachment strings to spin freely. tuck away or trim any loose
attachment strings. Loose and spinning attachment strings
can entangle your fingers or snag on the workpiece.
