SAFETYOPERATIONMAINTENANCE SETUP

Personal safety

1. 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.

2. Use personal protective equipment.

non-skid safety shoes, hard hat, or

hearing protection used for appropriate

conditions will reduce personal injuries.

3. Prevent unintentional starting.

Ensure the Switch is in the off-position

before connecting to power source, picking

up or carrying the tool.

Carrying power tools with your finger on

the Switch or energizing power tools that

have the Switch on invites accidents.

4. Do not overreach. Keep proper

footing and balance at all times.

This enables better control of the power

tool in unexpected situations.

5. Dress properly. Do not wear loose clothing

or jewelry. Keep your hair, clothing

and gloves away from moving parts.

Loose clothes, jewelry or long hair

can be caught in moving parts.

6. If devices are provided for the connection

of dust extraction and collection

facilities, ensure these are connected

and properly used. Use of these devices

can reduce dust-related hazards.

7. Only use safety equipment

that has been approved by an

appropriate standards agency.

Unapproved safety equipment may

not provide adequate protection.

Eye protection must be ANSI-approved and

breathing protection must be NIOSH-approved

for the specific hazards in the work area.

match the mounting hardware of the power

tool will run out of balance, vibrate excessively

and may cause loss of control.

7. Do not use a damaged accessory.

Before each use inspect the accessory

such as abrasive wheels for chips and

cracks, backing pad for cracks, tear or

excess wear, wire brush for loose or

cracked wires. If power tool or accessory

is dropped, inspect for damage or install

an undamaged accessory. After inspecting

and installing an accessory, position

yourself and bystanders away from the

plane of the rotating accessory and run

the power tool at maximum no-load speed

for one minute. Damaged accessories will

normally break apart during this test time.

SAFETY OPERATION MAINTENANCESETUP

Safety Warnings Specific for Grinding and

Abrasive Cutting-off Operations

1. Use only wheel types that are

recommended for your power tool and

the specific guard designed for the

selected wheel. Wheels for which the

power tool was not designed cannot be

adequately guarded and are unsafe.

2. Wheels must be used only for

recommended applications. For example:

do not grind with the side of cut-off wheel.

Abrasive cut-off wheels are intended for

peripheral grinding, side forces applied to

these wheels may cause them to shatter.

3. Always use undamaged wheel flanges

that are of correct size and shape for your

selected wheel. Proper wheel flanges support

the wheel thus reducing the possibility of

wheel breakage. Flanges for cut-off wheels

may be different from grinding wheel flanges.

4. Do not use worn down wheels from larger

power tools. Wheel intended for larger

power tool is not suitable for the higher

speed of a smaller tool and may burst.

5. Dress appropriately.

Do not wear pants with cuffs,

shirts with open pockets, or any clothing that

can catch and hold molten metal or sparks.

Safety Warnings Specific for Wire Brushing Operations

Be aware that wire bristles are thrown by the brush even during ordinary operation.

Do not overstress the wires by applying excessive load to the brush.

The wire bristles can easily penetrate light clothing and/or skin.

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. 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.

SAVE THESE INSTRUCTIONS.

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.
