JET JAT-101 (01) PDF Document

The specifications for the JET JAT-101, as well as the related JAT-104 and JAT-105 models, are listed below:

Read and understand the entire manual before attempting assembly or operation.

Always wear approved safety glasses or face shield while using this tool. Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.

Wear ear protectors (plugs or muffs) if the noise exceeds safe levels.

Wear gloves and protective clothing if operation produces sparks or flying particles. Gloves should be tight-fitting, without frayed fingers or hanging threads.

Adopt a comfortable posture with proper balance, and maintain secure footing at all times. Non-slip footwear or anti-skid floor strips are recommended.

Do not wear loose clothing or jewelry. Confine long hair.

Check air hoses for wear, and keep them away from heat and sharp edges. Repair or replace damaged air hose immediately. Do not carry tool by the air hose.

Shut off air supply and discharge any residual pressure from tool before removing hose, making adjustments, changing accessories, or storing tool.

Do not operate this tool while tired or under the influence of drugs, alcohol, or any medication.

This impact wrench is designed for removing and installing threaded fasteners. If you are not familiar with the proper and safe operation of a pneumatic impact wrench, do not use until proper training and knowledge have been obtained.

Use only impact sockets in good condition. Sockets in poor condition may reduce impact power, and could break, creating a safety hazard.

Use only sockets designated for use with impact wrenches. Never use hand tool sockets, as they can shatter.

Never hold socket, drive or drive extension with your hand during operation.

Make sure workpiece is secure and will not shift while operating impact wrench. Do not hold workpieces with your hand.

Make sure fastener can withstand rated torque of impact wrench.

1. Remove protective cap from air inlet. If an in-line oiler is not being used, add 4 or 5 drops of air tool oil into the air inlet.

2. Blow out air line to remove any dirt or moisture, then connect air supply hose to tool. Set air pressure to 90 psi.

Important: Connecting a quick-change coupling directly to the tool is not recommended, as vibration may cause the connection to fail. Instead, add a leader hose and install any quick-change couplings farther down the line.

3. Push drive socket (not included) onto anvil until it clicks into position.

4. Rotate regulator dial to preferred setting. Regulator settings are for reference only and do not indicate specific power settings. Rotate right for forward direction (3 speeds). Rotate left for reverse (1 speed).

1. Select reverse rotation.

2. Place socket over nut, hold grip firmly, and place other hand over top of housing. Gently squeeze trigger.

Important: If tool cannot loosen nut, DO NOT raise air pressure above 90 psi. If tool’s air regulator is in low setting, raise setting and retry. If tool’s regulator is already at maximum, do not continue attempts to loosen nut with this impact wrench. Use other methods or tools to loosen nut.

3. Release trigger to stop impact wrench.

1. Install nut as far as possible by hand.

2. Select forward rotation.

3. Place socket over nut, hold grip firmly, and place other hand over top of housing. Gently squeeze trigger.

Important: If tool stalls while tightening, DO NOT raise air pressure above 90 psi. If tool’s air regulator is in low setting, raise setting and retry. If nut will not tighten on maximum setting, do not continue attempts to tighten nut with this impact wrench. Use other methods or tools to tighten nut.

4. Release trigger to stop impact wrench.

Note: Do not overtighten. Fasteners with critical torque settings should be fully tightened with a torque wrench.

The impact wrench should be lubricated daily (or before each use) with air tool oil through the air inlet. During continual operation, it should be re-oiled every 1 to 2 hours. This can be done with an in-line oiler, or manually.

If done manually, proceed as follows:

1. Disconnect air hose from tool.

2. Place 4 or 5 drops of air tool oil into air inlet. SAE #10 oil or sewing machine oil may be used as a substitute. Do not use detergent oil.

3. Re-connect air. Run impact wrench at low throttle without load for a few seconds to distribute the oil throughout tool.

4. When finished operating impact wrench, disconnect air hose. Wipe off housing with a dry cloth. Place 4 or 5 drops of air tool oil into air inlet; re-connect air and run the tool for a few seconds to distribute the oil. Disconnect air.

The impact clutch in the housing is pre-greased and should not require further lubrication.

1. Use proper air hose size (refer to tool specifications). The hose should be just long enough to serve the working area. Excessive hose length will cause pressure drop.

2. Make sure air compressor supplies clean, dry air at correct CFM for the impact wrench.

3. Set air pressure to 90 psi. Excess air pressure and/or unclean air will shorten the tool’s life and may create a hazardous situation.

4. Drain water from air compressor tank daily, as well as any condensation from air lines. Water in the air line may enter the tool and cause damage.

5. Change filters on the air system on a regular basis.

6. Air-line pressure may be increased accordingly to compensate for extra-long air hoses (usually over 25 feet). Inside diameter of hose should be minimum 3/8-inch.

If it takes more than 8 seconds to tighten or loosen a bolt or nut with an air impact wrench at maximum setting, the air wrench is too small or the air compressor CFM is not powerful enough for the job. Continued use in either capacity will cause damage to the tool.
