SERVICE
21.
Tool service must be performed only by
qualified repair personnel. Service or main-
tenance performed by unqualified personnel
may result in a risk of injury.
22.
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
shock or injury.
SPECIFIC SAFETY RULES
USB070-1
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to cordless 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.
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.
5.
NEVER hold piece being cut in your hands
or across your leg. It is important to support
the work properly to minimize body exposure,
wheel binding, or loss of control.
6.
Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring.
Contact with a “live” wire will also make
exposed metal parts of the tool “live” and
shock the operator.
7.
When ripping always use a rip fence or
straight edge guide. This improves the
accuracy of cut and reduces the chance for
wheel binding.
8.
Always use wheels with correct size and
shape (diamond vs. round) arbor holes.
Wheels that do not match the mounting hard-
ware of the tool will run eccentrically, causing
loss of control.
9.
Never use damaged or incorrect wheel
washers or bolts. The wheel washers and
bolt were specially designed for your tool, for
optimum performance and safety of opera-
tion.
10.
Causes and Operator Prevention of Kick-
back:
Kickback is a sudden reaction to a pinched,
bound, or misaligned wheel, causing an
uncontrolled tool to lift up and out of the work-
piece toward the operator.
When the wheel is pinched or bound tightly
by the kerf closing down, the wheel stalls and
the motor reaction drives the unit rapidly back
toward the operator.
If the wheel becomes twisted or misaligned in
