Description

The Aircat Neumatic Tools Tire Buffer 6400 is engineered to provide top-notch performance in tire maintenance. Its robust 4.0 HP motor ensures that the tool can handle tough grime and discoloration with ease. The high-speed operation at 3,000 RPM allows for quick and efficient buffing, saving time and effort. The ergonomic design of the tool features a comfortable grip that reduces user fatigue, making it ideal for extended use.

The tool comes with multiple buffing pads that can be easily swapped out depending on the specific needs of the job. It also includes a carrying case for convenient storage and transport. Built with durable materials, this tire buffer is designed to withstand the rigors of frequent use in professional settings.

Air Supply

Tools of this class operate on a wide range of air pressure. It is recommended that air pressure of these tools measures 90 PSI at the tool while running free.
Higher pressure and unclean air will shorten the tool’s life because of faster wear and may create a hazardous condition and void the warranty.
Water in the air line will cause damage to the tool.
Drain the air tank daily.
Clean the air inlet filter screen on at least a weekly schedule. The recommended hookup procedure can be viewed in the illustration below.
The air inlet, used for connecting air supply, has standard 1/4” NPT American Thread.
Line pressure should be increased to compensate for unusually long air hoses (over 25 feet).
Minimum hose diameter should be 3/8” I.D. and fittings should have the same inside dimensions.

Setup Guide

To operate the Aircat Neumatic Tools Tire Buffer 6400,

Start by ensuring you have a reliable air compressor that can supply the necessary 6 CFM at 90 PSI.
Connect the air hose to the tool and ensure all connections are secure.
Choose the appropriate buffing pad for your task and attach it to the tool according to the manufacturer's instructions.

Hold the tool firmly but comfortably,

Use the ergonomic grip to your advantage. Turn on the air supply and begin buffing the tire surface in circular motions, applying moderate pressure as needed.

For assembly,

Simply attach the buffing pad and ensure all parts are securely in place.
No complicated configuration is required; the tool is ready to use right out of the box.

Maintenance

Other factors outside the tool may cause loss of power or erratic action.
Reduced compressor output, excessive drain on the air line, moisture or restriction in air pipes or the use of hose connections of improper size or poor condition may reduce air supply.
Grit or gum deposits in the tool may cut power and may be corrected by cleaning the air strainer and flushing out the tool with gum solvent oil or an equal mixture of SAE#10 oil and kerosene.
If outside conditions are in order and tool is out-of-warranty, disconnect tool from hose, disassemble tool, replace worm or damaged parts, clean, reassemble, and re-lubricate, or take tool to any air tool service center.
For tools in warranty period, send tool direct to Warranty Center.

Lubrication

Ensure the air line is shut-off and drained of air before removing this tool for service or changing sockets. This will prevent the tool from operating if the throttle is accidentally engaged.
An in-line filter-regulator-lubricator is recommended as it increases tool life and keeps the tool in sustained operation.
Regularly check and fill the in-line lubricator with air tool oil. Avoid using excessive amounts of oil.
Adjust the in-line lubricator by placing a sheet of paper next to the tools exhaust ports and holding the throttle open approximately 30 seconds. The lubricator is properly set when a light stain of oil collects on the paper.
If it is necessary to store the tool for an extended period of time (overnight, weekend, etc.), generously lubricate the tool through the air inlet. Run the tool for approximately 30 seconds to ensure the oil is evenly distributed throughout the tool. Store the tool in a clean and dry environment.

Recommended lubricants: Air tool oil or any other high grade turbine oil containing moisture absorbent, rust inhibitors, metal wetting agents, and an EP (extreme pressure) additive.

Important Warnings

Tire Buffers

Only use mounted grinding stones or mounted carbide burrs that meet ANSI standards, ISO standards or both.
Never adjust the tire buffer, adjust the collets or change the mounted stones or mounted burrs unless the air supply and air hose is disconnected from the tire buffer.
Only personnel trained in the correct methods to adjust collets and change mounted stones and mounted burrs should conduct these operations.
Always ensure that you are aware of the direction of the sparks being created by the grinding operation and ensure that the sparks are not directed toward the operator or other persons in the area.
Never use tire buffer close to any explosive or flammable materials or air conditioners.
Only use mounted stones or carbide burrs that have the correct spindle diameter that matches the original collet size provided by the die grinder manufacturer.
Particular care must be taken not to use metric size mounted stones and mounted burrs with tire buffers that have imperial size collets, or use imperial mounted stones and mounted burrs with tire buffers that have metric collets.

WARNING: This product contains lead, a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling
