SPECIFICATIONS

Some dust created by power sanding, sawing, grinding, drilling, and other

construction activities contains chemicals known to cause cancer, birth

defects or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this

type of work. To reduce your exposure to these chemicals: work in a well

ventilated area, and work with approved safety equipment, such as those

dust masks that are specially designed to filter out microscopic particles.

Slow Rivet Setting Performance

Troubleshoot and resolve issues causing the tool to take more than two strokes to set a rivet.

The SX1819TV is a 1/4" heavy-duty vacuum rivet gun designed for various construction and assembly activities. This air-powered tool is engineered for efficiency and durability, offering a robust solution for setting rivets.

Function Description:

The rivet gun operates by utilizing compressed air to actuate a hydraulic plunger mechanism. When the trigger lever is depressed, the throttle valve opens, allowing air to enter the air cylinder and force the piston assembly upward. This action, in turn, drives the hydraulic plunger, which retracts and causes the jaws to grip the rivet mandrel. The tool then pulls the rivet until it is securely set and the mandrel breaks. Upon releasing the lever, the throttle valve resets, cutting off the air supply. The valve tube spring lifts the valve tube, exhausting air through its hollow, while the return spring brings the hydraulic plunger back to its original position. This process releases the mandrel and retracts the piston assembly, preparing the tool for the next operation. The vacuum feature aids in collecting broken mandrels, contributing to a cleaner and safer work environment.

Important Technical Specifications:

Rivet Capacity: 1/4"
Traction Power: 3,960 lbf.
Stroke Length: 3/4"
Air Inlet: 1/4" NPT
Air Supply Hose Size: 3/8" I.D.
Working Air Pressure: 70-100 psig (6.2 bar)
Height: 12-1/2"
Weight: 5.7 lb.

Usage Features:

The SX1819TV is designed for ease of use and operator safety. It requires a clean, dry air supply, with a recommended pressure of 90 psig at the tool for optimal performance. The tool is equipped with a vacuum system that helps manage broken mandrels, preventing them from scattering in the workspace.

Key operational aspects include:

Nosepiece Changing: The nosepiece can be easily changed by hooking up the tool to the air line, depressing the lever, and using a maintenance tool to remove and tighten the nosepiece. A circular opening should be visible through the hydraulic section when the tool is at rest, indicating proper installation.
Jaw Cleaning and Changing: The jaws can be cleaned or replaced by disconnecting the tool from the air line, removing the head with a maintenance tool, and then detaching the jaw housing. Regular cleaning with a steel brush or solvent, or replacement if worn, ensures optimal performance. A thin coat of oil should be applied to the sliding surface of the jaws during reassembly.
Jaw Opening Adjustment: To achieve maximum stroke, the distance between the jaw housing and the head must be correctly set. This involves loosening the lock nut, inserting a rivet of the appropriate size, and then screwing or unscrewing the head to achieve the minimum jaw opening while ensuring the rivet mandrel can be freely inserted and removed. The lock nut must be fastened after adjustment.
Safety Precautions: Operators are advised to always read the manual, wear eye, hearing, and face protection, and avoid prolonged exposure to vibration. The tool should not be used on live electrical circuits or in explosive atmospheres. It is crucial to disconnect the air supply before any assembly, disassembly, or maintenance procedures. The exhaust port should be kept pointed away from the face.

Maintenance Features:

Regular maintenance is essential for the longevity and performance of the SX1819TV.

Lubrication: The air motor should be lubricated daily with high-quality air tool oil. If an air line oiler is not used, 1/2 oz. of oil should be run through the tool by squirting it into the air inlet or hose. Rust inhibitive oil is also acceptable.
Connection Tightness: Periodically check the tightness of all connections, including the jaw housing coupler, nut, jaw housing, hydraulic plunger, nosepiece, head, and lock nut.
Jaw Inspection: Regularly inspect the jaws for excessive wear or dirt and follow the servicing procedures for cleaning or replacement as needed.
Air Supply Maintenance: Ensure the air supply is clean and dry. Drain water from air lines and the compressor regularly, and clean the air inlet filter screen weekly.
Troubleshooting: The manual provides guidance for common issues such as the rivet mandrel being gripped but not setting, the mandrel not fitting or ejecting, and the tool requiring multiple strokes to set a rivet. Remedies include increasing air pressure (up to 100 psig max), checking for worn o-rings, cleaning or replacing jaws, and ensuring correct nosepiece size and tightness.

The SX1819TV is a robust and reliable tool, but adherence to the instructions and warnings is critical to prevent personal injury and property damage. The product contains chemicals known to cause cancer and birth defects, so users are advised to wash hands thoroughly after handling, especially brass parts containing lead.
