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:
1. 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 medical or
physical 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. Use tools with the lowest vibration when there
is a choice between different processes.
4. Include vibration-free periods each day of work.
5. Grip workpiece as lightly as possible (while still
keeping safe control of it). Let the tool do the work.

Procedures not specifically explained in this manual must
be performed only by a qualified technician.
TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:
Turn the Power Switch of the tool off and unplug the tool from its electrical outlet
before performing any procedure in this section.
TO PREVENT SERIOUS INJURY FROM TOOL FAILURE:
Do not use damaged equipment. If abnormal noise or vibration
occurs, have the problem corrected before further use.
Cleaning, Maintenance, and Lubrication
1. BEFORE EACH USE, inspect the general
condition of the tool. Check for:
• loose hardware,
• misalignment or binding of moving parts,
• cracked or broken parts,
• damaged electrical wiring, and
• any other condition that may
affect its safe operation.

of the tool with clean cloth.
3. Periodically, wear ANSI-approved
safety goggles and NIOSH-approved
breathing protection and blow dust and grit out
of the motor vents using dry compressed air.
4. WARNING! If the supply cord of this
power tool is damaged, it must be replaced
only by a qualified service technician.
Dressing the Grinding Wheel
Note: New wheels frequently are not true and
during operation will often become grooved, glazed
(build up), out of round, or misshapen. You will
need a grinding wheel dresser for this operation.
Dressers are available from Harbor Freight Tools.
1. Stand to the side of the wheel for this operation.
2. If the wheel is new let it run for a minute with no
load. If the wheel runs straight and true, you will
not need to dress it prior to operation. If it does
not, proceed with the following instructions.
3. If you are using a “pistol grip” dresser, grip the
handle firmly with one hand and the arm of
the dresser with the other. Allow the wheel to
reach full speed. Use the tool rest to support
your hand and the dresser, and evenly apply
the dresser to all surfaces of the wheel. The
wheel can be dressed in a few minutes.
4. If you are using an “inline” dresser, hold the handle
firmly, put the dresser on the tool rest so that its
wheels can move freely (i.e., the exposed part of the
wheel should be facing up). Let the wheel reach full
speed and apply the dresser evenly to all surfaces.
Accessory Storage and Handling
1. Handle accessories carefully to prevent
dropping or bumping. Do not use wheels
that have been dropped or bumped.
2. Store accessories in shelves, racks, boxes, or
drawers. Keep storage area dry and above

Limited 90 Day Warranty
Harbor Freight Tools Co. makes every effort to assure that its products meet high quality and durability standards,
and warrants to the original purchaser that this product is free from defects in materials and workmanship for the
period of 90 days from the date of purchase. This warranty does not apply to damage due directly or indirectly,
to misuse, abuse, negligence or accidents, repairs or alterations outside our facilities, criminal activity, improper
installation, normal wear and tear, or to lack of maintenance. We shall in no event be liable for death, injuries
to persons or property, or for incidental, contingent, special or consequential damages arising from the use of
our product. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the
above limitation of exclusion may not apply to you. THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY AND FITNESS.
To take advantage of this warranty, the product or part must be returned to us with transportation charges
prepaid. Proof of purchase date and an explanation of the complaint must accompany the merchandise.
If our inspection verifies the defect, we will either repair or replace the product at our election or we may
elect to refund the purchase price if we cannot readily and quickly provide you with a replacement. We will
return repaired products at our expense, but if we determine there is no defect, or that the defect resulted
from causes not within the scope of our warranty, then you must bear the cost of returning the product.
This warranty gives you specific legal rights and you may also have other rights which vary from state to state.
