Do you have a question about the Sumake ST-6615 and is the answer not in the manual?

The SUMAKE ST-6615 is a 3/16" (4.8mm) Air Hydraulic Riveter, designed for efficient riveting operations in various industrial applications. This tool is part of the SUMAKE PNEUMATIC TOOLS range, known for its professional and industrial-grade equipment.

Function Description:

The ST-6615 is an air-powered hydraulic riveter that uses compressed air to generate hydraulic pressure, which in turn pulls and sets rivets. It is capable of handling blind rivets of various sizes, making it a versatile tool for assembly and repair tasks. The tool is designed to inject high efficiency into manual chipping, riveting, and breaking of concrete and asphalt, although its primary function as described in the manual is riveting. The operation involves placing a rivet into the nosepiece, aligning it with the workpiece, and then activating the trigger to pull and set the rivet. The tool's design allows for adjustments to accommodate different rivet sizes and stroke lengths, ensuring precise and secure fastening.

Important Technical Specifications:

Blind Rivet Setting Capacity: The ST-6615 can set blind rivets of multiple sizes: 3/32" (2.4mm), 1/8" (3.2mm), 5/32" (4.0mm), and 3/16" (4.8mm). This broad capacity makes it suitable for a wide range of applications.
Traction Power: The tool provides a traction power of 1586 lbs (720kg), indicating its strength in pulling rivets securely.
Piston Stroke: It features a piston stroke of 9/16" (14 mm), which is crucial for the proper setting of rivets.
Overall Length: The riveter has an overall length of 10-3/4" (273 mm), making it a compact and manageable tool.
Air Inlet (PT): The air inlet is 1/4" (6.35 mm), a standard size for pneumatic tools.
Air Hose (I.D.): A 3/8" (10 mm) inner diameter air hose is recommended for optimal performance.
Air Pressure: The tool operates at an optimal air pressure of 90 psi (6.3 bar). The manual warns that higher pressures can cause damage or excessive wear, while lower pressures (below 5.3 bar) can lead to pressure or power loss.
Net Weight: Weighing 3.3 lbs (1.5 kg), the ST-6615 is relatively lightweight, reducing user fatigue during extended use.
Vibration (EN ISO 20643): The vibration emission value (Load) is 5.06 m/s², with an uncertainty (K) of 1.5 m/s².
Noise (EN ISO 15744): The sound pressure level (No load) is 90.4 dB(A), and the sound power level (No load) is 101.4 dB(A), with an uncertainty (K) of 3dB. Users are advised to always wear ear protection when the environmental noise level exceeds 80 dB(A) to prevent impaired hearing.

Usage Features:

Rivet Setting Process: The tool requires the user to aim the rivet at the workpiece, ensuring the rivet head size matches the workpiece. Rivets are then inserted into the nosepiece.
Nosepiece and Jaw Changes: The nosepiece can be easily loosened with an anticlockwise turn of a wrench for changing. The jaw case can also be disassembled using two wrenches for changing jaws or adjusting the jaw case joint and lock nut to modify the stroke length.
Hydraulic Oil Refilling: The cylinder cap can be loosened with a wrench to add hydraulic fluid. It is crucial not to connect air when adding hydraulic oil. The piston must be pulled out, hydraulic oil reloaded to the O-ring of the cylinder body, and grease applied to the piston's O-ring before reassembling. Hydraulic oil #R68 is recommended.
Stroke Length Adjustment: The stroke length may need adjustment if the tool is not running smoothly, which can be done by loosening the jaw case joint and lock nut. A wrench is used to check the stroke length at the correct position.
Air Connection: The tool connects to an air hose via a fitting. The manual recommends applying 4 to 5 drops of SAE 10W-20 (ISO Viscosity Grade 46/32) Hydraulic Oil at the air inlet every 3 to 4 hours of operation. Teflon thread tape should be used to ensure a proper seal.
Safety Precautions: The manual emphasizes several safety guidelines, including wearing ear protectors, avoiding pointing the air hose at others, shutting off air supply before maintenance or accessory changes, and checking hoses and couplings for damage. It also advises against using the tool if any problems occur and to have it maintained by qualified personnel.

Maintenance Features:

Regular Lubrication: The air tool requires lubrication throughout its life. The air motor and bearings use compressed air to start the tool, and moisture in compressed air can rust the motor, necessitating daily lubrication.
Oil Level Management: Users should keep the hydraulic oil at an optimum level. A gradual loss of oil may occur with use, and a reduction in stroke indicates a need to add more oil.
Filter and Air Inlet Maintenance: The filter (Fig. 1) and air inlet of the tool should be kept dry.
Quick Connect Coupling Lubrication: Lubricating the quick connect coupling prevents blocking.
Storage: The tool should not be stored in high humidity environments. If left as is, residual moisture can cause rust. Before storage, lubricate the tool and run it for a few seconds.
Inspection: Regular inspection of spindles, threads, and clamping devices for wear and tolerances is recommended.
Jaw Case Cleaning: Insure that jaws are clean and free of metal shavings, dirt and oil.
Troubleshooting Guide: The manual provides a comprehensive troubleshooting guide for common issues:
- Rivet is jammed: This could be due to a wrong size rivet, filings in the jaw case, or filings on the nosepiece top. Remedies include changing the nosepiece/jaw/jaw joint, disassembling the frame head or jaw case to clean out filings, or using a sharp tool to remove filings.
- Air leaking: Often caused by damaged O-rings or loose screws. O-rings need replacement, and screws need tightening.
- Stroke length is not correct: This indicates a damaged or deformed frame O-ring, which needs replacement.
- Tool runs slow or has loss of power: Possible causes are a loose air feeding tube or operating pressure that is too low. Re-installing and tightening the tube or increasing operating pressure to 85-95 psi are the solutions.
- Hydraulic oil is not enough: If the rivet can't pull out or has no power, the cylinder cap should be opened, and hydraulic oil reloaded into the tool.
Disposal: If the tool is too seriously damaged for use, it should be recycled as raw material, not disposed of as waste. The machine, accessories, and packaging should be sorted for environmental-friendly recycling, with local authority or retailer consultation.

The SUMAKE ST-6615 is a robust and reliable tool, designed for professional use, with clear guidelines for operation, maintenance, and safety to ensure its longevity and user well-being.
