Product Overview
The Sealey 10.8V SV10.8 Series 3/8" Square Drive Cordless Impact Wrench is a compact and lightweight tool designed for efficient fastening and loosening tasks. It features a robust housing with a soft grip handle to minimize vibration during operation. The tool is equipped with an integrated LED worklight to illuminate the work area and an LED battery level indicator to monitor power status. Please note that this is a body-only model; it requires a compatible 10.8V 2Ah or 4Ah Lithium-ion battery and a mains charger, which are sold separately.

Safety Instructions
Safety is paramount when operating power tools. Always ensure the impact wrench is switched off before installing the battery pack. Keep the tool and charger clean and in good condition. Before starting, evaluate the work area for potential hazards such as hidden electrical wiring or water pipes. Wear appropriate personal protective equipment, including safety eye protection, ear protection, and gloves. Maintain a stable footing and balance at all times. Do not operate the tool near flammable liquids, gases, or solids. Avoid unintentional starting by keeping the direction switch in the locked position when the tool is not in use. Never leave the tool operating unattended or carry it with your finger on the power switch.
Operation and Usage
To operate the wrench, first fit a compatible impact-grade socket onto the square drive. Insert the battery pack by aligning the tongue with the housing groove until it clicks into place. Select the desired direction of rotation using the direction selector; never attempt to change the direction while the trigger is depressed. Speed is controlled by varying the pressure applied to the trigger. Initial pressure will activate the LED worklight. When tightening, exercise caution to avoid over-torquing small fixings. For critical applications, always verify the final torque with a manual torque wrench according to manufacturer guidelines.
Battery Maintenance
To ensure optimal battery performance and longevity, avoid fully discharging the battery. It is recommended to fully charge the battery after every use. If the tool is not used for an extended period, charge the battery at least every four months. If you notice a decrease in tool performance, recharge the battery immediately.
Maintenance and Storage
The tool is permanently lubricated and does not require special internal maintenance. Before performing any cleaning or adjustments, always remove the battery. Clean the exterior with a soft bristled brush or a soft damp cloth. Do not use solvents or compressed air, as these can damage the tool or cause debris to be ejected. Store the tool in a dry, child-free location. Professional repairs should only be conducted by an authorized service agent.
