Vibration Hazard
This appliance 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 appliances 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 appliance. If you
feel any symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use appliances with the lowest vibration when
there is a choice between different processes.
5. Include vibration-free periods each day of work.
6. Grip appliance as lightly as possible
(while still keeping safe control of it).
Let the appliance do the work.
7. To reduce vibration, maintain the appliance
as explained in this manual. If any abnormal
vibration occurs, stop use immediately.
General Safety
1. use only for water or water-based fertilizers,
herbicides, pesticides and sealers. Do not use
to spray combustible or corrosive chemicals.

chemicals sprayed, including MSDS
instructions and Epa regulations.
3. Do not point the Sprayer at yourself,
other people or animals.
4. Industrial applications must follow
OSHA requirements.
5. Make sure the liquid used in the Sprayer
is not dirty, sandy or viscous.
6. This product is not a toy. Do not allow
children to play with or near this item.
7. Inspect before every use; do not use
if parts are loose or damaged.

Harbor Freight Tools for a replacement.
10. 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.
