The ESCO Model #90455 Manual Tire Spreader, Turn-Table Style, is a robust and portable tool designed to facilitate various tire repair and maintenance tasks. Its primary function is to spread the beads of passenger vehicle, small truck, and small bus tires, allowing for easier access to the inner tire for repair, polishing, and cleaning. The "Turn-Table Style" indicates its design, which likely incorporates a rotating base for optimal positioning of the tire during service.

Function Description:

The tire spreader is engineered to aid in the repair process by holding the tire in an open, spread position. This allows technicians to perform detailed work on the inner liner of the tire, such as patching, buffing, and inspecting for damage. The adjustable spreader arms are designed to fit securely on the inside beads of the tire. Once positioned, a heavy metal arm is used to spread the beads open, providing ample working space. This manual operation ensures precise control over the spreading action. The device is particularly useful for tasks that require a clear and stable view of the tire's interior, making intricate repairs more manageable and efficient. Its design also allows for easy integration with existing workshop equipment, specifically wheel clamp tire changers, or it can be mounted on a workbench.

Important Technical Specifications:

Overall Height: The device stands at 12.25 inches, indicating a compact design suitable for tabletop use.
Overall Width: With an overall width of 11 inches, it maintains a relatively small footprint in a workshop environment.
Overall Length: The length of the spreader is 25.5 inches, providing sufficient leverage and support for spreading tires within its specified range.

Usage Features:

Table-top Design: The compact and stable design makes it ideal for use on a workbench or integrated with a tire changer.
Portability: Its relatively light weight and compact dimensions contribute to its high portability, allowing it to be easily relocated within a service department or transported as needed.
Compatibility with Tire Changers: The metal mounting base plate can be securely held between the clamping jaws of most wheel clamp tire changers. This feature allows the operator to position the tire at an optimal height and angle for repair, enhancing ergonomic efficiency and ease of access.
Workbench Mounting Option: For workshops without a tire changer or for dedicated repair stations, the spreader can be permanently mounted to a workbench using the pre-drilled holes on its base. This provides a stable and secure setup for frequent use.
Adjustable Spreader Arms: The design includes adjustable arms that can be adapted to fit various tire sizes within the specified width range, ensuring versatility.
Manual Operation: The use of a heavy metal arm for spreading the tire beads provides direct control to the operator, which can be beneficial for delicate or precise repair work.
Assembly Process: The manual outlines a straightforward assembly process involving attaching the movable claw support to the table, bolting the moving claw with the support, and finally placing the tire spreader assembly on the base plate and tightening the handle wheel bolt. This indicates a user-friendly setup.

Maintenance Features:

Cleaning: Users are instructed to regularly clear any dust, dirt, and debris that may accumulate in the spreader hooks or on the machine. This prevents operational issues and maintains the tool's effectiveness. Keeping the hook and claw clean, especially from grease, is crucial to avoid operator injury caused by slippage.
Fastener Inspection: It is essential to ensure that all fasteners are tightened and in proper operating order. Regular checks prevent loosening during use and maintain the structural integrity of the device.
Lubrication: The manual recommends regular lubrication of the oil pin and any friction surfaces. This practice is vital for reducing resistance during operation and extending the overall lifespan of the machine.
Damage Inspection: Users are advised not to use the product if it is visibly worn, distorted, or damaged. This emphasizes safety and the importance of pre-use inspection.
Disposal: Proper disposal of the product must adhere to local rules and regulations concerning waste disposal, highlighting environmental responsibility.

Safety Precautions:

The manual includes a prominent "WARNING" section, emphasizing that the product, like all tire tools, should only be used by persons trained according to OSHA regulations 29CFR 1910.177, specifically "SERVICING SINGLE-PIECE & MULTIPIECE RIM WHEELS." Failure to read instructions can void the warranty or lead to serious injury. The "CAUTION" section further advises reading the manual and all warnings before use to prevent injury and product damage. It also specifies that the product should only be used for spreading tires and repairing the protective wrap, and not for any other purpose, to avoid issues for which ESCO would not be responsible. Appropriate eye protection is also recommended during the repair process to prevent eye injury.
