and specifications provided with this power tool.
Failure to follow all instructions listed below may
result in electric shock, fire and/or serious injury.
Save all warnings and instructions
for future reference.
1. PRIOR TO USING THIS PRODUCT, READ
AND UNDERSTAND ALL INSTRUCTIONS
AND SAFETY PRECAUTIONS AS OUTLINED
IN THE MANUFACTURER’S MANUAL OF
THE SCREWGUN THAT IS TO BE USED.
2. This product is not a toy. Do not allow
children to play with or near this item.

4. Keep hands clear of moving parts.
5. Maintain labels and nameplates on
the tool. These carry important safety
information. If unreadable or missing, contact
Harbor Freight Tools for a replacement.
6. Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication.
A moment of inattention while operating power
tools may result in serious personal injury.
7. The warnings, precautions, and instructions
discussed in this instruction manual cannot
cover all possible conditions and situations
that may occur. It must be understood by the
operator that common sense and caution are
factors which cannot be built into this product,
but must be supplied by the operator.
8. Vibration Safety
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:
a. Anyone using vibrating tools regularly or for an
extended period should first 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 symptoms
related to vibration (such as tingling,
numbness, and white or blue fingers), seek
medical advice as soon as possible.
b. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
c. Wear suitable gloves to reduce the
vibration effects on the user.
d. Use tools with the lowest vibration
when there is a choice.
e. Include vibration-free periods each day of work.
f. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
g. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.
