• Hold power tools using the insulated gripping surfaces when performing an operation where the
cutting tool may come into contact with hidden wiring or its own cord� Contact with a “live” wire
will cause exposed metal parts of the tool to become “live” and shock the operator�
• Let bits cool before touching, changing or adjusting them� Bits heat up dramatically while in use,
and can burn you�
• If the drill bit jams, release the trigger immediately; Drill torque can cause personal injury or
damage the bit�
• Maintain labels and nameplates on the tool� These carry important safety information�
• If unreadable or missing, contact Harbor Freight Tools for a replacement�
• Avoid unintentional starting�
• Prepare the job before turning on the tool�
• Do not carry or lay the tool down until it has come to a complete stop� Moving parts can get
stuck in the surface and pull the tool out of your control�
• When using a handheld power tool, maintain a firm grip on the tool with both hands to resist
starting torque�
• Do not leave the tool unattended when it is plugged into an electrical outlet� Turn off the tool,
and unplug it from its electrical outlet before leaving�
• This product is not a toy�
• Keep it out of the reach of children�
• People with pacemakers should consult their physician(s) before use� Electromagnetic fields in
close proximity to a heart pacemaker may cause pacemaker interference or pacemaker failure�
In addition, people with pacemakers should:
– Avoid operating the tool alone�
– Not use with power switch locked in the on-position�
– Carefully maintain the tool to avoid electrical shocks�
• All power cords must be properly grounded� Residual current devices should also be used�
• To prevent serious personal injury as a result of accidental operation: Release the trigger and
unplug the tool from its electrical outlet before performing any inspection, maintenance, or
cleaning procedures�
• Do not use damaged equipment� If abnormal noise or vibration occurs, have the problem
corrected before further use�
WARNING!
Some dust created by, for example by power sanding, sawing, grinding and drilling
contains chemicals known to cause cancer, birth defects or other reproductive disorders� Some
examples of such chemicals are:
– Lead from lead-based paints
– Crystalline silica from bricks, cement or other masonry products
– Arsenic and chromium from chemically treated lumber�
– Your risk from exposure to these substances varies, depending on how often you do this
type of work� To reduce your exposure to these chemicals: work in well ventilated areas,
and use approved safety equipment, such as dust masks that are specially designed to
filter out microscopic particles�
• The warnings, precautions, and instructions discussed in this handbook cannot cover all possible
conditions and situations that may occur� Users must understand that common sense and
caution are factors which cannot be built into this product, but are factors that users themselves
must be responsible for�
Vibrations
This tool vibrates during use� Repeated or long-term exposure to vibrations may cause temporary
or permanent physical injury, in particular to the hands, arms and shoulders� Reducing the risk of
vibration-related injury:
• Anyone using vibrating tools regularly or for an extended period should initially be examined
by a doctor and then have regular medical check-ups to ensure medical problems are not being
caused or worsened from use� Pregnant women or people who have impaired blood circulation
to the hands, previous hand injuries, nervous system disorders, diabetes, or Raynaud’s Disease
should not use this tool�
• If you feel any symptoms related to vibration (such as tingling, numbness, and white or blue
fingers), seek medical advice as soon as possible�
• Do not smoke during use� Nicotine reduces the supply of blood to the hands and fingers,
increasing the risk of vibration-related injuries�
• Wear suitable gloves to reduce the effects of vibration on the user�
• Where there is a choice, use tools with the lowest amount of vibration possible�
• Include vibration-free periods during the work day�
• Grip the tool as lightly as possible (while still keeping safe control of it)� Let the tool do the work�
• To reduce vibration, maintain the tool as explained in this manual� If any abnormal vibration
occurs, stop use immediately�
Extension cords
• Grounded tools require a three-wire extension cord� Double-insulated tools can use either
a two-wire or three-wire extension cord�
• The longer the distance from the power outlet, the heavier the gauge of the extension
cord used�
• Using extension cords with an inadequate wire dimension causes a serious drop in voltage,
resulting in loss of power and possible tool damage�
• Make sure the extension cord has the correct number of wires and is in good electrical
condition� Always replace a damaged extension cord or have it repaired by a qualified
electrician before use�
• Protect the extension cords from sharp objects, excessive heat, and damp or wet areas�
