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
USB049-2
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to cutout tool safety
rules. If you use this tool unsafely or incorrectly, you can suffer
serious personal injury.
1.
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.
2.
Wear eye protection and dust mask.
3.
Ventilate your work area adequately.
4.
Check the bit carefully for cracks or dam-
age before operation. Replace cracked or
damaged bit immediately.
5.
Check for the proper clearance beneath
the workpiece before cutting so that the
bit will not strike a hard surface such as
the floor, workbench, etc.
6.
Do not cut metal objects such as nails and
screws. Inspect for and remove all nails,
screws and other foreign material from
the workpiece before operation.
7.
Check that the bit is not contacting the
workpiece before the switch is turned on.
Always hold the tool with two hands while
switching the tool on. The motor torque
can cause the tool to turn.
8.
Before using the tool on an actual work-
piece, let it run for a while. Watch for
vibration or wobbling that could indicate
improperly installed bit.
9.
Make sure that the shaft lock is released
before the switch is turned on.
