Safety Warnings and Precautions

WARNING: When using product, basic safety precautions should always be

followed to reduce the risk of personal injury and damage to equipment.

1. Keep work area clean. Cluttered areas invite injuries.

2. Observe work area conditions. Keep work area well lighted. Always keep

children our of work area.

3. Store idle equipment. When not in use, the Indicator must be stored in a dry

location. Always lock up products and keep out of reach of children.

4. Use the right product for the job. There are certain applications for which the

Indicator was designed. Do not modify the Indicator and do not use the Indicator

for a purpose for which it was not intended.

5. Check for damaged parts. Before using any product, any part that appears

damaged should be carefully checked to determine that it will operate properly

and perform its intended function. Check for any broken or damaged parts and

any other conditions that may affect its operation. Repair damaged or worn

parts immediately.

6. Do not operate product if under the inﬂuence of alcohol or drugs. Read

warning labels on prescriptions to determine if your judgment or reﬂexes are

impaired while taking drugs. If there is any doubt, do not operate the product.

7. Use eye protection. Always wear ANSI approved impact safety goggles.

8. Battery strength will affect readings. Use fresh battery at all times.

Warning: The warnings, cautions, 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.

Operation

Your Digital Indicator requires no assembly. It is important that you read the

entire manual to become familiar with the product BEFORE you use the Digital

Indicator.

Do not bump or shock the tool when applying it to any work piece. Rough

treatment may damage the highly sensitive mechanism.

Note: There are many applications for the Digital Indicator. On the following page

is one example of how this product can be used: testing brake rotors for true. Make

certain to clean off all brake components with brake parts cleaner before testing.

Unpacking

When unpacking your Digital Indicator, check to make sure that the product is

intact and undamaged. If any parts are missing or broken, please call

HARBOR FREIGHT TOOLS at 1-800-444-3353.

Operation (Continued)

Note: Digital Indicators are highly versatile tools used in many applications in

machine shops and precision fabricating and testing facilities. The procedure

discussed below (testing brake rotors for true) is only an example, and details

how to use this measuring tool.

1. Push the “On/Off” Button (see Figure 1) to “ON”. Set the Indicator lightly against

a rotor to establish a baseline. Clamp the Indicator in place so that only the

Indicator will move. Push the Zero Button to set the dial to zero. You do not

want the Indicator too tight against the object being measured. There must be

room for the needle to move in and out while under pressure.

2. Spin the rotor to see if it is true. As the rotor spins, the needle will move in and

out. The dial will indicate the degrees of difference in true; the measurements

which are above and below the baseline you established at the beginning. Press

the inch/mm Button to have the Indicator dial read in inches or millimeters. Each

time the button is pressed the reading will switch between inches and mm.

Replacing the Battery

1. Remove the battery cover located directly on the top of the Digital Indicator by

gently prying it off-see Figure 2.

2. Replace the battery with the type speciﬁed on page two. Insert into the

compartment with the positive polarity facing the front of the product.

3. Replace the battery cover. Dispose of the old battery in accordance with local

ordinances for proper disposal.

Maintenance

1. Protect the Digital Indicator from rough use. It is susceptible to damage from

being dropped, struck with a test piece, improperly mounted or other abuse.

The precision movement is similar to a watch works, and should be treated

accordingly.

2. Protect the Indicator from exposure to water or corrosive materials. It should

be kept clean and dry. Occasional cleaning with a clean rag will extend its life

and good appearance.

3. Lock it up and store in a dry location to inhibit rust. Keep out of the reach of

children. Before storing the instrument for extended periods of time, take out

battery.

Note: No replacement parts are available for this product.
