Do you have a question about the Sealey SA203 and is the answer not in the manual?

This document describes the Sealey Power Tools SA203 Air Impact Wrench, a 1/2" square drive mini twin hammer air impact wrench designed for various workshop applications.

Function Description:

The SA203 is a powerful air impact wrench featuring a twin hammer mechanism, housed in a compact design. Its primary function is to provide high torque for fastening and loosening nuts and bolts, making it suitable for garage, tire shop, and general workshop applications. The handle exhaust design helps reduce noise output and limits the circulation of brake dust, which is particularly beneficial when working on wheel applications. The wrench incorporates a three-position torque/air control for both forward and reverse operations, allowing for versatile use in different scenarios. Its mini size is advantageous for accessing confined engine bay areas.

Important Technical Specifications:

Working/Maximum Torque: 375/400 lb.ft
Ultimate Torque: 450 lb.ft
Speed: 11000 rpm
Air Consumption: 5.8 cfm
Operating Pressure: 90 psi
Air Inlet Size: 1/4" BSP
Weight: 1.6 kg
Drive: 1/2" Sq
Noise Power: 104.45 dB(A)
Noise Pressure: 93.45 dB(A)
Measured Vibration Emission Value (a): 5.8 m/s²
Uncertainty Value (k): 0.648 m/s²

Usage Features:

Safety First: Users are strongly advised to follow all workshop safety rules, regulations, and conditions. It is crucial to disconnect the wrench from the air supply before changing accessories or performing any servicing. Approved safety eye/face shields, ear defenders, and hand protection must be worn. When working around vehicle brake systems, suitable respiratory protection is recommended due to the potential presence of asbestos dust.
Air Supply Requirements: The wrench requires an air pressure of 90 psi and an air flow according to specifications. The air supply must be clean and free from moisture; daily draining of the compressor air tank and weekly cleaning of the compressor air inlet filter are essential. The recommended hook-up procedure involves a water separator, oiler, and regulator.
Hose Management: The air hose should be kept away from heat, oil, and sharp edges. It must be checked for wear before each use, and all connections must be secure. Line pressure may need to be increased for unusually long air hoses (over 8 meters), and the minimum hose diameter should be 1/4" I.D. with fittings of the same inside dimensions.
Couplings: To prevent vibration-induced failure, a leader hose should be connected directly to the wrench, with a quick-change coupling then used to connect the leader hose to the air line recoil hose.
Socket Compatibility: Only impact sockets specifically designed for use with an impact wrench should be used. Worn or damaged sockets must not be used.
Operation: To operate, place the socket over the nut and depress the trigger. The air regulator on the rear of the body allows for changing direction and regulating air flow across three positions.
Ergonomics and Control: Maintain correct balance and footing, wearing non-slip shoes. Keep children and non-essential persons away from the working area. Do not carry the wrench by the air hose or yank the hose from the air supply. Avoid operating the wrench if tired or under the influence of alcohol, drugs, or intoxicating medication. Do not carry the wrench with a hand on the power trigger to prevent unintentional starting.
Vibration Management: The tool's vibration emission is closely linked to operating pressure. Users should ensure the pressure is set according to recommendations to optimize efficiency and minimize vibration exposure. Avoid using ill-fitting or worn sockets and extensions, as this increases vibration. Ensure the tool is correctly aligned to the work, and consumables are selected, maintained, and replaced as per Sealey instructions. Support the tool in a stand or on a balancer where possible. Hold the tool with a light but secure grip, avoiding excessive force.
Final Tightening: A calibrated torque wrench should be used for final tightening of fasteners.

Maintenance Features:

General Maintenance: The wrench must be maintained in good condition, with any damaged or worn parts replaced using genuine parts only. Unauthorized parts are dangerous and will invalidate the warranty.
Lubrication: If the air system lacks an oiler, lubricate the air wrench daily with a few drops of Sealey air tool oil dripped into the air inlet. The gearbox should be checked and topped up by removing the grub screw located under the impact head. Regularly lubricate the drive shaft to reduce friction and increase power and longevity.
Cleaning: Clean the wrench after each use.
Troubleshooting Power Loss: Loss of power or erratic action can be due to excessive drain on the air line, moisture or restriction in the air pipe, or incorrect hose connectors. To remedy, check the air supply and follow the instructions in Section 3. Grit or gum deposits can also reduce performance; if the model has an air strainer, it should be removed and cleaned. Flush the wrench with gum solvent oil or an equal mixture of SAE No.10 oil and paraffin, then allow to dry before use.
Storage: When not in use, disconnect the wrench from the air supply, clean it, and store it in a safe, dry, childproof location.
Professional Service: For a full service, contact a local Sealey service agent.
Health Surveillance: A program of health surveillance is recommended to detect early symptoms of vibration injury, allowing management procedures to be modified accordingly.
Personal Protective Equipment (PPE): While no specific PPE provides protection against vibration injury from uncontrolled use, a sufficient supply of clothing (including gloves) is recommended to keep the operator warm and dry and maintain good blood circulation in the fingers. Prevention is the most effective protection, as detailed in the Correct Use and Maintenance sections.
