Sealey STW901 Wrench F.A.Q.

How do I calibrate the Sealey STW901 Wrench?

To calibrate the Sealey STW901 Wrench, you need to follow the manufacturer's instructions included in the manual. Typically, this involves setting the wrench to a known torque value and testing it against a calibration device.

What should I do if the Sealey STW901 Wrench is not clicking at the set torque?

Ensure the wrench is properly set to the desired torque value and that the fastener is not over-tightened. If the problem persists, it may require recalibration or servicing.

What is the correct way to store the Sealey STW901 Wrench?

Store the wrench in a dry and clean environment, ideally in its case. Make sure to set the wrench to its lowest torque setting to relieve tension on the spring mechanism.

How often should I recalibrate my Sealey STW901 Wrench?

Recalibration is recommended every 12 months or after 5,000 cycles, whichever comes first. Frequent use may necessitate more frequent recalibration.

Can the Sealey STW901 Wrench be used in reverse torque applications?

The Sealey STW901 Wrench is designed for right-hand (clockwise) torque applications. Using it for reverse torque could damage the tool and compromise accuracy.

Why is it important to use the Sealey STW901 Wrench at the correct torque setting?

Using the correct torque setting ensures that fasteners are neither too loose nor too tight, preventing potential damage or failure of the assembly.

How can I tell if my Sealey STW901 Wrench is damaged?

Check for visible signs of wear, such as cracks or deformations. If the wrench fails to hold calibration or does not click at the set torque, it may be damaged.

What maintenance is required for the Sealey STW901 Wrench?

Regularly clean the wrench with a dry cloth and lightly lubricate the mechanism with a suitable lubricant. Avoid using excessive force to maintain accuracy and longevity.

Is it possible to repair a Sealey STW901 Wrench myself?

While some minor maintenance can be done at home, such as cleaning and lubrication, calibration and complex repairs should be performed by qualified professionals.

How can I ensure the accuracy of my Sealey STW901 Wrench during use?

Ensure the wrench is calibrated, use it within the specified torque range, and apply slow and steady pressure until the wrench clicks to maintain accuracy.
