The VAR DV-10000 is a consumer torque wrench designed for precise torque application on bolts and fasteners, with a torque range of 3 to 14 Newton meters (Nm). This tool is specifically engineered to ensure accurate tightening, preventing both over-tightening, which can damage components and the wrench's ratcheting mechanism, and under-tightening, which can lead to loose parts. The wrench boasts an accuracy of +/- 4%, making it a reliable tool for various applications where specific torque values are critical. The units of measurement displayed on the wrench are in Newton meters (N.m).

The DV-10000 comes as a comprehensive set, including the 3-14 Nm torque wrench itself, five hexagonal bits (3, 4, 5, 6, and 8 mm), and two Torx® bits (T25 and T30). This assortment of bits allows for versatility across a range of fastener types commonly encountered in consumer applications.

Function Description:

The primary function of the DV-10000 is to apply a predetermined torque to threaded fasteners. Users set the desired torque value using a locking ring and a scale window. Once the set torque is reached during tightening, the wrench provides an audible "click" and a tactile feedback, signaling that the correct torque has been applied. This mechanism ensures that fasteners are tightened to their specified values, which is crucial for the safety, performance, and longevity of assembled components. The wrench is designed for single, gentle movements during torque application, and it is important to hold the wrench at the center of the handle for accurate results.

Usage Features:

Setting Torque: To set the desired torque, the user pushes a locking ring to unlock it, then turns the ring until the red index line aligns with the desired torque setting in the scale window. For values between markings (e.g., 3Nm), the index line should be centered between the two relevant markings (e.g., 2Nm and 4Nm), with the locking ring aligned to the "1" setting on the triple V-shaped arrow. Once the desired torque is set, releasing the locking ring allows spring tension to automatically return it to the "lock" position.
Bit Installation: Appropriate bits are fitted onto the square head of the torque wrench.
Applying Torque: The component's threaded fastener is tightened with steady force. The user must stop immediately upon hearing and feeling the "click" from the wrench, indicating that the preset torque has been reached. It's important to note that the wrench will not automatically stop applying torque once the preset value is achieved; the user must cease force application.
First Use/Long Storage Lubrication: To ensure optimal internal lubrication, especially during the first use or after extended storage, it is recommended to dial a high torque setting and make the wrench "click" a few times by pushing the head with the thumb. This helps to distribute the internal lubricant.
Safety Precautions:
- Never use the wrench beyond its maximum torque setting (14Nm) or to loosen threaded fasteners. Over-torquing can damage the wrench's accuracy and ratcheting mechanism.
- The DV-10000 should not be used as a standard ratcheting wrench.
- Always refer to component manufacturers' recommended torque specifications to prevent improper tightening.

Maintenance Features:

Storage: The torque wrench should be stored carefully in a clean and dry place.
Cleaning: Clean the wrench with a dry cloth. Avoid using water and solvents, as these can compromise the internal lubricant and potentially damage the tool.
Resetting Torque for Storage: After each use, especially when storing the torque wrench, it is crucial to dial the lowest torque setting. This practice helps to relieve tension on the internal spring mechanism, preserving its accuracy and extending the tool's lifespan.
Avoiding Damage: The DV-10000 is a precision tool and should be handled with care. Avoid shocks, falls, and general mistreatment to maintain its accuracy and functionality.

The VAR DV-10000 is a specialized tool designed to bring precision to home mechanics and enthusiasts, ensuring that components are assembled correctly and safely according to manufacturer specifications.
