When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance instructions may create a risk of
electric shock or injury.
USE PROPER EXTENSION CORD: Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy enough to carry the current your
product will draw. An undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. Table 1 shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage num-
ber, the heavier the cord.
SPECIFIC SAFETY RULES
USB047-3
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to polisher safety rules.
If you use this tool unsafely or incorrectly, you can suffer seri-
ous personal injury.
1.
Accessories must be rated for at least the
speed recommended on the tool warning
label. Wheels and other accessories running
over rated speed can fly apart and cause
injury.
2.
Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring or
its own cord. Contact with a “live” wire will
make exposed metal parts of the tool “live”
and shock the operator.
3.
Check the backing pad carefully for
cracks, damage or deformity before oper-
ation. Replace cracked, damaged or
deformed pad immediately.
4.
NEVER use tool with wood cutting blades
or other sawblades. Such blades when
used on a polisher frequently kick and
cause loss of control leading to personal
injury.
5.
Hold the tool firmly.
6.
Keep hands away from rotating parts.
7.
Make sure the abrasive disc or wool bon-
net is not contacting the workpiece before
the switch is turned on.
