REMOVE ADJUSTING KEYS AND WRENCHES. Make it a habit to check that keys and
adjusting wrenches are removed from the tool or machine work surface before plugging
it in.
AVOID UNINTENTIONAL STARTING. Be sure the switch is in the OFF position when
not in use and before plugging in. Do not carry any tool with your finger on the trigger,
whether it is plugged in or not.
OUTDOOR EXTENSIONS CORDS. When the equipment is operated outdoors, use
only extension cords intended or outside use. See chart under “Extension Cords: for the
proper AWG rating depending on the length of the cord(s) being used.
STAY ALERT. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
CHECK DAMAGED PARTS. Before using any tool, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment and binding of moving parts; any broken parts or
mounting fixtures; and any other condition that may affect proper operation. Any part that
is damaged should be properly repaired or replaced by a qualified technician. Do not use
the tool if any switch does not turn on and off properly.
GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded surfaces
such as pipes, radiators, ranges, and refrigerator enclosures.
REPLACEMENT PARTS AND ACCESSORIES. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty. Only use accessories
intended for use with this tool. Approved accessories are available from Harbor Freight
Tools.
DO NOT OPERATE TOOL IF UNDER THE INFLUENCE OF ALCOHOL OR DRUGS.
Read warning labels on prescriptions to determine if your judgment or reflexes are im-
paired while taking drugs. If there is any doubt, do not operate the tool.
ONLY USE IMPACT SOCKETS. Sockets built for impact wrenches are specifically de-
signed to withstand the force of the delivered blow. Any other socket may shatter, caus-
ing injury to the operator and damage to any nearby equipment.
People with pacemakers should consult their physician(s) before use. Electromagnetic
fields in close proximity to heart pacemaker could cause pacemaker interference or
pacemaker failure. In addition, people with pacemakers should:
• Avoid operating alone.
• Do not use with power switch locked on.
• Properly maintain and inspect to avoid electrical shock.
• Any power cord must be properly grounded. Ground Fault Circuit Interrupter (GFCI)
should also be implemented – it prevents sustained electrical shock.
Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities, contains chemicals known [to the State of California] to cause cancer, birth
defects or other reproductive harm. Some examples of these chemicals are:
Lead from lead-based paints
Crystalline silica from bricks and cement or other masonry products
