Frequently Asked Questions - 073-008 Meec Tools

What type of air compressor is needed for the Meec Tools 073-008 impact wrench?

You need a compressor that can supply sufficient air flow at a regulated pressure of 6.2 bar. The tool's average air consumption is 226 l/min. Ensure the compressor has a minimum hose inner diameter of 3/8" for optimal performance.

How do I adjust the torque setting on the impact wrench?

The torque is adjusted using the air regulator located beside the air intake. Settings range from 1 (minimum torque for small nuts) to 4 (maximum torque). Refer to the manual for specific torque ranges.

How to properly lubricate the pneumatic impact wrench?

Lubricate after every 1-2 hours of operation. Disconnect the air supply, apply 4-5 drops of compressed air oil (SAE 10 or sewing machine oil) into the air intake, reconnect the hose, and run the tool for a few seconds to distribute the oil evenly. Do not use high-viscosity oil.

What safety precautions should I follow when using this tool?

Always wear eye protection, hearing protection (if noise exceeds 85 dB(A)), a dust mask, and gloves. Ensure secure footing, use both hands, keep work area clean, and disconnect air hose before adjustments. Do not use in explosive atmospheres.

Why is the tool running slowly or at varying speeds?

Possible causes: insufficient air flow (low pressure), blocked or kinked air hose, faulty speed regulator, or worn rotor blades. Check the hose, compressor pressure, and replace rotor blades if necessary.

How to store the impact wrench when not in use?

Disconnect the air hose, apply 4-5 drops of pneumatic oil into the air intake, run the tool for 30 seconds to distribute oil, then store in a dry location to prevent corrosion.

What is the maximum torque of the Meec Tools 073-008?

The maximum torque is 340 Nm. Use a torque wrench to verify final tightening torque if required.

How to change the direction of rotation (forward/reverse)?

For loosening (reverse), press the switch above the trigger so it protrudes from the rear of the casing. For tightening (forward), press the switch forward so it protrudes from the front. Then squeeze the trigger to operate.

What should I do if the tool starts on its own when connected to air?

Immediately disconnect the air hose. The trigger catch or trigger may be defective, or there is an air leak. Inspect and repair the trigger mechanism, and locate and seal any leaks before further use.

Is the tool repairable and where can I find spare parts?

Yes, the tool is serviceable. For spare parts and repairs, contact Jula's service department. Follow the troubleshooting guide in the manual for common issues.

Always use hearing protection!

The declared vibration value, which has been measured by a standardised test method, can be used to compare different tools with each other and for a preliminary assessment of exposure.

Warning! The actual vibration level when using power tools may differ from the specified maximum value, depending on how the tool is used. It is therefore necessary to determine which safety precautions

are required to protect the user, based on an estimate of exposure in actual operating conditions (taking into account all stages of the work cycle, e.g. the time when the tool is switched off and when it is idling, in addition to the start-up time).

The figures quoted are emission levels and are not necessarily safe working levels. Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not further precautions are required. Factors that influence the actual level of exposure of the workforce include the characteristics of the work room and the other sources of noise etc. i.e. the number of machines and other adjacent processes. Also the permissible exposure level can vary from country to country. This information, however, will enable the user of the machine to make a better evaluation of the hazard and risk.

OPERATION

Use

The torque is set using the tool's air regulator, which is located beside the air intake. 1 indicates the minimum torque, suitable for small nuts, and 4 indicates the maximum torque.

Loosening

1. Attach a suitable size socket onto the holder.
2. Set the compressor's pressure regulator to 6.2 bar. Do not set the pressure higher than 6.2 bar.
3. Connect the air hose to the tool. If a leak is detected, disconnect the air hose immediately. Do not use the tool until the leak has been repaired.
4. Place the socket over the nut that is to be loosened.
5. Hold the tool firmly. Press in the switch above the trigger so that it protrudes on the rear of the casing. The tool is now set for backwards rotation (loosening). Start the tool by squeezing the trigger. IMPORTANT: Check that the nut can withstand the set torque.

NOTE!

• Do not increase the pressure in the compressor's pressure regulator if the tool cannot undo the nut.
• If the tool's torque setting is low, you can increase this setting and try again. Do not continue attempting to undo the nut if the tool's regulator is already in position 4. Undo the nut in another way.
• When the nut has been undone, stop the tool by releasing the trigger. Lift the socket away from the nut. Remove the nut from the socket, if necessary.

Tightening/screwing in

The impact wrench has a maximum torque of 340 Nm. Check that the nut can withstand the set torque.

1. Hand screw the nut on as far as possible.
2. Place the socket over the nut that is to be loosened. Press the switch above the trigger forwards so that it protrudes on the front of the casing. The tool is now set for forwards rotation (tightening). Start the tool by squeezing the trigger.

NOTE!

• Do not increase the pressure in the compressor's pressure regulator if the tool cannot tighten the nut all the way.
• If the tool's torque setting is low, you can increase this setting and try again. Do not continue trying to tighten the nut if the tool's regulator is already in position 4. Tighten the nut in another way.
• When the nut has been tightened, lift the socket away from the nut. Do not overtighten.
• If possible, check the recommended tightening torque for the nut and check the tightening torque with a torque wrench after tightening with the impact wrench.

Compressed air supply

1. Check that the relevant compressor provides sufficient air flow.
2. The tool must always be turned off when it is connected to the compressed air supply.
3. Normal operating air pressure for the tool is 6.2 bar. Excessively high pressure and contaminated air cause the tool to wear unreasonably quickly, and can also entail a risk of personal injury or damage to property.
4. Drain off any water from the compressor's air container daily. Otherwise, water from the air hoses can penetrate the tool and damage it.
5. Clean the air intake filter cartridge each week. The chart below shows the recommended connection.
6. If hoses are very long (normally longer than 8 metres), the line pressure must be increased to compensate for the pressure drop. The minimum inner diameter of the hose is 1/4". Couplings must have the same inner diameter. An air hose with an inner diameter of 3/8" is normally recommended for optimum tool function.
7. Use appropriate hoses and couplings. We do not recommend connecting quick-release couplings directly to the tool, as they can cause malfunction as a result of vibration. Instead, connect a hose to the tool and install a quick-release coupling between the air hose from the compressor and the anti-vibration hose that is attached to the tool.
8. Keep the hose away from heat, oil and sharp edges. Check each hose for wear before use. Make sure that all connections are secure.

MAINTENANCE

Lubrication

• The tool can be lubricated with a line-mounted lubricating device or manually. During manual lubrication, disconnect the compressed air supply, apply a few drops of compressed air oil in the tool's air intake and operate the tool for a few seconds. Oil SAE 10 or sewing machine oil can be used. Do not use flushing oil.
• Before connecting the air hose, apply 4 or 5 drops of compressed air oil in the air intake. Reconnect the air hose and press the trigger a few times to distribute the oil evenly. Do not use oil with a high viscosity. This can impair the tool's performance.
• Lubricate the tool after every 1 or 2 hours of operation.
• Before putting the tool away after use, disconnect the air hose and apply 4 or 5 drops of pneumatic oil in the air intake. Reconnect the air hose and operate the tool for approx. 30 seconds to distribute the oil evenly. This will ensure the tool lasts longer.
• Clean the air intake filter cartridge each week.

Storage

- Do not store the tool in a damp location. This can result in corrosion damage to the mechanism. Always lubricate the tool before storage.
