Need help?Do you have a question about the Aircat 6255 and is the answer not in the manual?
Failure to oil the tool can void your warranty, emphasizing proper lubrication.
Tools are warranted for 2 years against defects in material and workmanship.
Warranty does not cover attached accessories, normal wear, abuse, misuse, or unauthorized repairs.
Recommended air pressure is 90 PSI for optimal tool life and safe operation.
Drain air tank daily, clean air inlet filter screen weekly to prevent damage.
Use 1/4" NPT thread for air inlet and 3/8" I.D. hose for optimal air supply.
Start the tool by depressing the throttle; release to stop. Always use two hands.
Always wear safety goggles and clothing. Never remove the disc guard.
Clean tool with gum solvent oil or SAE#10 oil/kerosene mix for grit/gum deposits.
Out-of-warranty repairs involve disassembly, part replacement, or service center visit.
For warranty service, send the tool to the Warranty Center with the warranty card.
The AIRCAT® Angle Die Grinder, Model #6255 /Composite, is a pneumatic tool designed for various grinding applications. This manual provides essential instructions for its safe operation, maintenance, and warranty information.
The Angle Die Grinder is a power tool that utilizes compressed air to drive a rotating spindle, allowing for precise material removal and shaping. It is designed to be used with various accessories, such as grinding bits, to perform tasks like deburring, polishing, and grinding in tight spaces. The tool's composite construction contributes to its lightweight design, enhancing user comfort and reducing fatigue during extended use. The grinder operates by depressing a throttle, which is spring-loaded and returns to the off position when released, ensuring immediate cessation of operation for safety.
Operating the Angle Die Grinder requires adherence to specific safety protocols to prevent personal injury and property damage. Before any operation, it is crucial to read all instructions thoroughly. The tool is designed to operate most efficiently when the air pressure measures 90 PSI at the tool while running free. Exceeding this pressure, specifically using the tool over 90 psi, is not recommended as its free speed will increase proportionally, potentially leading to unsafe conditions and premature wear.
Personal protective equipment is mandatory during operation. Users must always wear protective eye gear to shield against flying debris and a dust mask to prevent inhalation of dust generated during grinding. Wearing gloves and protective clothing is also advised to avoid injuries from malfunctioning attachments or improperly clamped workpieces.
Proper handling of the tool is emphasized. It should not be carried with a finger on or near the throttle or trigger when connected to the air supply, nor should it be carried by the hose. Protecting the air hose from sharp objects and heat is also important for its longevity and safe operation. The tool should always be used at a safe distance from other people in the work area to prevent accidental injury.
Before changing any accessory on the tool, it is imperative to disconnect it from the air supply. Similarly, no service work should be performed on the tool while it is connected to the air supply. If a sudden change in the feel or sound of the unit occurs, the tool should be immediately turned off, and the head inspected for damage. Users are explicitly warned against attempting to alter any part of the tool in any way, shape, or form, as this can compromise its safety and performance. The manual also stresses the importance of using both hands when operating the tool and explicitly states, "DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE THE DISC GUARD." When not in use, disconnecting the tool from the air supply prevents accidental or unauthorized use.
The air inlet, used for connecting the air supply, has a standard 1/4" NPT American Thread. To compensate for unusually long air hoses (over 25 feet), line pressure should be increased. The minimum hose diameter should be 3/8" I.D., and all fittings should have the same inside dimensions to ensure adequate air supply.
Proper maintenance is critical for the longevity and optimal performance of the Angle Die Grinder. A significant portion of air tool problems, approximately 90%, are caused by moisture in air lines. This issue can be prevented by consistently using air tool lubricant. Lubrication should be performed daily with a good grade of air tool oil. The motor should be lubricated before each use. If an in-line lubricator is not employed, a few drops of oil should be added into the air inlet daily, taking care not to flood the tool with oil. Additionally, the head gears require daily greasing.
Water in the air line can cause severe damage to the tool; therefore, the air tank should be drained daily. The air inlet filter screen also requires regular cleaning, at least on a weekly schedule, to prevent contaminants from entering the tool.
Other factors can lead to loss of power or erratic action, including reduced compressor output, excessive drain on the air line, moisture, or restriction in air pipes, or the use of improperly sized or poor condition hose connections. Grit or gum deposits within the tool can also reduce power. These issues can often 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.
For tools outside the warranty period, if external conditions are in order, users can disconnect the tool from the hose, disassemble it, replace worn or damaged parts, clean, reassemble, and re-lubricate, or take it to any air tool service center. For tools still under warranty, they must be sent directly to a Warranty Center, accompanied by the warranty card for service. Any repair attempts by unauthorized personnel (other than an AIRCAT or Florida Pneumatic Authorized Service Center) are not covered by the warranty. Normal wear and tear, abuse, misuse, or modification of the tool are also excluded from warranty coverage. The warranty applies only to the tool itself and does not cover attached accessories or consumable products such as drill chucks, sander backing pads, air hammer retainers and chisels, or "kit" accessories.
