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 USB003-2

DO NOT let comfort or familiarity with product (gained from

repeated use) replace strict adherence to impact wrench 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 tool live and
shock the operator.
2. Wear ear protectors.
3. Check the socket carefully for wear,
cracks or damage before installation.
4. Hold the tool firmly.
5. Always be sure you have a firm footing.
Be sure no one is below when using the
tool in high locations.
6. The proper fastening torque may differ
depending upon the kind or size of the
bolt. Check the torque with a torque
wrench.
