Introduction
This manual provides essential instructions for the safe and effective use of your OEMTOOLS 25687 Click Style Torque Wrench. This precision tool is designed for accurate tightening of fasteners within a range of 25 to 250 foot-pounds (33.90 to 337.60 Newton-meters). Proper use ensures fasteners are tightened to manufacturer specifications, preventing under or over-torquing.

Safety Information
- Always wear appropriate personal protective equipment, such as safety glasses, when using tools.
- Do not use the torque wrench as a breaker bar. This can damage the internal mechanism and affect accuracy.
- Ensure the fastener and socket are clean and free of debris before use.
- Store the torque wrench in its protective case when not in use to maintain calibration.
- Do not exceed the maximum torque rating of 250 ft-lbs (337.60 Nm).
Setup and Torque Setting
The OEMTOOLS 25687 torque wrench features an easy-to-use twist handle for setting the desired torque value. It includes dual scales for both foot-pounds (ft-lb) and Newton-meters (Nm).
- Unlock the Handle: Locate the locking collar at the base of the handle. Pull down the locking collar to unlock the handle for adjustment.
- Set Desired Torque: Rotate the handle clockwise to increase the torque setting or counter-clockwise to decrease it. Align the desired torque value on the main scale with the zero mark on the micrometer scale. Then, rotate the handle further until the exact desired value on the micrometer scale aligns with the main scale line.
- Lock the Handle: Push the locking collar back up to secure the handle in place. This prevents accidental changes to the torque setting during operation.

Operating Instructions
Once the torque is set, the wrench is ready for use. It operates in both clockwise and counterclockwise directions.
- Attach Socket: Select the correct size socket for your fastener and attach it firmly to the 1/2-inch drive head of the torque wrench.
- Position Wrench: Place the socket onto the fastener. Ensure the wrench is positioned to allow for a smooth, continuous pull.
- Apply Force: Apply steady, increasing force to the handle. Do not jerk or apply sudden force.
- Listen for the Click: Continue applying force until you hear and feel a distinct "click." This indicates that the preset torque value has been reached. Immediately stop applying force.
- Release Pressure: Remove the wrench from the fastener.
- Important Note: If using a 1/2-inch drive extension, be aware that the flex in the extension can alter the output torque. Account for this when setting your target torque.

Maintenance and Storage
- Cleaning: After each use, wipe the torque wrench clean with a soft, dry cloth. Do not use solvents or harsh chemicals, as these can damage the finish or internal components.
- Storage: Always return the torque wrench to its lowest torque setting (25 ft-lbs) before storing. This relieves tension on the internal spring mechanism, helping to maintain accuracy over time.
- Protective Case: Store the wrench in its provided heavy-duty blow mold case. This case protects the tool from impacts, dust, and moisture, which are crucial for preserving its calibration and longevity.
- Calibration: Torque wrenches are precision instruments and should be periodically checked for calibration by a qualified service center, especially after heavy use or if dropped.
