SPECIFIC SAFETY RULES
GEB009-2
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 per-
sonal injury.
1.
Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord.
Con-
tact with a “live” wire will make exposed metal parts
of the tool “live” and shock the operator.

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.

high locations.
6.
The proper fastening torque may differ depend-
ing upon the kind or size of the bolt. Check the
torque with a torque wrench.
SAVE THESE INSTRUCTIONS.
WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.
