SERVICE
23.
Tool service must be performed only by
qualified repair personnel.
Service or main-
tenance performed by unqualified personnel
could result in a risk of injury.
24.
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
USB072-1
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to cutter safety rules. If
you use this tool unsafely or incorrectly, you can suffer serious
personal injury.
1.
DANGER! Keep hands away from cutting
area and wheel. Keep your second hand
on auxiliary handle or motor housing.
If
both hands are holding the tool, they cannot
be cut by the wheel.
2.
Keep your body positioned to either side
of the wheel, but not in line with the wheel.
KICKBACK could cause the tool to jump
backwards. (See “Causes and Operator Pre-
vention of Kickback”)
3.
Do not reach underneath the work.
Do not
attempt to remove cut material when wheel is
moving.
CAUTION: Wheels coast after turn off.
4.
Always observe that the wheel has
stopped spinning before placing tool
down on bench or floor.
A coasting wheel
will cause the tool to walk backwards, cutting
whatever is in its path. Be aware of the time it
takes for the wheel to stop after switch is
released.
