VIBRATION HAZARD
This tool vibrates during use. Repeated or long-term exposure to vibration may
cause temporary or permanent physical injury, particularly to the hands, arms
and shoulders. To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an extended period should rst
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 hand, past hand injuries,
nervous system disorders, diabetes, or Raynaud’s Disease should not use this
tool. If you feel any medical or physical symptoms related to vibration (such as
tingling, numbness, and white or blue ngers), seek medical advice as soon as
possible.
2. Do not smoke during use. Nicotine reduces the blood supply to the hands and
ngers, increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the vibration effects on the user.
4. Use tools with the lowest vibration when there is a choice between different
processes.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping safe control of it). Let the tool
do the work.
7. To reduce vibration, maintain the tool as explained in this manual. If any
abnormal vibration occurs, stop use immediately.
SERVICE
1. Have product serviced by a qualied repair person using only identical
replacement parts. This will ensure that the safety of the product is maintained.
2. Maintain labels and nameplates on the product. These carry important safety
information. If unreadable or missing, contact Harbor Freight Tools for a
replacement.
MISCELLANEOUS
1. Use compressed air only. Only use clean, dry and regulated compressed air at
no more than 90 PSI to power this tool. Never use oxygen, carbon dioxide or
any other bottled gas as a power source for this tool.

2. WARNING: The brass components of this product contain lead, a chemical
known to the State of California to cause birth defects (or other reproductive
harm). (California Health & Safety code § 25249.5, et seq.)
3. WARNING: 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
Arsenic and chromium from chemically treated lumber
Your risk from these exposures varies, depending on how often you do this type
of work. To reduce your exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such as those dust masks that
are specially designed to lter out microscopic particles. (California Health &
Safety Code § 25249.5, et seq.)
4. The warnings, precautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. It must be
