Tool Specifications

¹ The specified values are emission levels and are not necessarily safe operating levels. This information is intended to help users estimate hazards and risks based on workplace conditions.

Specifications were current at publication but are subject to change without notice due to JET's policy of continuous improvement.

Setup and Assembly

Report any missing parts or damage immediately to your JET distributor. Do not use a damaged tool. Read this manual thoroughly for operation, maintenance, and safety instructions.

Box Contents:

• 1 Pneumatic drill
• 1 Chuck key
• 1 Dead handle (JAT-601 only)
• 1 Operation and parts manual
• 1 Warranty card

For Model JAT-601 only: To install the dead handle (Figure 1), rotate the handle counterclockwise to loosen the retainer. Slide the retainer over the chuck and onto the drill body, then rotate to a convenient angle and retighten the handle to secure. Ensure the chuck remains clear of the retainer.

Operation:

[Caution Symbol: Tool Damage] The pneumatic drill must be properly lubricated before operation. Refer to the "Lubrication" section.

Figure 1: Shows the drill with labels for Chuck key, Trigger, Fwd/Rev selector, Retainer, Handle, and Air Inlet. The JAT-601 model is indicated as having a Handle.

1. Remove the protective cap from the air inlet (Figure 1). If an in-line oiler is not used, add 4 or 5 drops of air tool oil (not included) into the air inlet.
2. Blow out the air line to remove dirt or moisture, then connect the air supply hose to the tool. Set air pressure to 90 psi.

IMPORTANT: Connecting a quick-change coupling directly to the tool is not recommended due to potential failure from vibration. Instead, use a leader hose and install quick-change couplings farther down the line.

3. Insert the chuck key into one of the holes on the chuck, meshing with the chuck's teeth. Rotate counterclockwise to open the chuck jaws.
4. Insert the drill bit (not provided) into the chuck, centering it between the jaws. Tighten the chuck by hand while aligning the bit. Note: Insert only the shank of a twist drill bit; its flutes should remain free of the chuck jaws.
5. Insert the chuck key and rotate clockwise to fully tighten the chuck.
6. Select the rotation direction (F/R).
7. Place the bit against the work item and gently press the trigger. Speed is variable based on trigger pressure. Start at a slow speed and gradually increase as you drill.
8. Release the trigger to stop the drill.

Maintenance

Lubrication

The drill should be lubricated daily (or before each use) with air tool oil through the air inlet. During continuous operation, re-oil every 1 to 2 hours, either manually or with an in-line oiler.

Manual Lubrication Steps:

1. Disconnect the air hose from the tool.
2. Place 4 or 5 drops of air tool oil into the air inlet. Note: Air tool oil is not provided but is available at most hardware stores. SAE #10 oil or sewing machine oil can be used as a substitute. Do not use detergent oil.
3. Reconnect the air. Run the drill at low throttle without a load for a few seconds to distribute the oil throughout the tool.
4. When finished operating, disconnect the air hose. Wipe the housing with a dry cloth. Place 4 or 5 drops of air tool oil into the air inlet, reconnect the air, and run the tool for a few seconds to distribute the oil. Then, disconnect the air.

Storage

Avoid storing the drill in very humid locations, as this promotes rusting of internal mechanisms. Always oil the tool and disconnect the air hose before storage.

Air System Requirements

1. Use the proper air hose size (refer to tool specifications). The hose should be just long enough for the working area; excessive length causes pressure drop.
2. Ensure the air compressor supplies clean, dry air at the correct CFM for the tool.
3. Set air pressure to 90 psi. [Caution Symbol: Tool Damage] Excess air pressure and/or unclean air will shorten the tool's life and may create a hazardous situation.
4. Drain water from the air compressor tank daily, as well as any condensation from air lines. Water in the air line can damage the tool.
5. Change filters on the air system regularly.
6. Air-line pressure may need to be increased for extra-long air hoses (over 25 feet). The inside diameter of the hose should be a minimum of 3/8-inch.

General Air Tool Information

If the air tool is not performing to specifications, common causes include:

• Contaminated air (dirty system or water).
• Using the wrong size tool for the job.
• Poor maintenance practices (e.g., excessive air pressure or volume).
• Improper or no lubrication.

Rule of Thumb

If it takes more than 8 seconds to tighten or loosen a bolt or nut with an air impact wrench at maximum setting, the wrench may be too small or the air compressor's CFM is insufficient for the job. Continued use in either case can damage the tool.

Tool Pressure

JET Air Tools operate on 70-to-100 psi (pounds per square inch) air pressure measured at the tool. Set the tool to 90 psi unless otherwise indicated. Pressure exceeding 100 psi will shorten the tool's life.

Air System Recommendations

• Equip the air compressor intake with a cleanable, replaceable air filter.
• Use safety shut-off valves to quickly stop airflow in case of a line break.
• When using multiple hoses, use hoses larger than the leader hose. Join multiple hoses directly, not with quick-connect fittings that can cause pressure drops and reduce tool power.
• Use anti-whip devices across hose couplings to prevent hose whipping if a hose fails or a coupling disconnects.
• Always use moisture traps at the compressor for the main distribution line. Use moisture traps and in-line oilers on each downline used for air tools (See Figure 2). Place oilers as close to the air tool as possible for best lubrication.

Lubrication

Use a light oil containing rust inhibitors, such as SAE #10. Many JET air tools have integral oil reservoirs that should be kept filled if in-line oilers are not used. If greasing is required, use a highly water-resistant grease for front case components on air impact wrenches, grinders, and sanders.

Recycling

Protect the environment. Your tool contains recoverable or recyclable materials. When its useful life expires, please leave the tool at a specialized facility.

Figure 2: Recommended arrangement of air piping and air line system

This diagram illustrates a typical air system setup. It shows an air compressor connected to an air tool. The air line includes a stop valve, a filter, a regulator, and an oiler. The diagram also shows an auto drain valve on the compressor and another stop valve in the line. The piping is shown with a slight downward slope (more than 1/100) towards the drain valve.
