Product FAQ's

Ask a Question

  • How do I set the torque on my Hydraulic Underwater Impact Wrench IW16?
    Stanley Impact Wrenches are not considered torque wrenches. You can adjust the tool close to a set torque, but it won't be exact. Please refer to your service manual for instructions on adjusting the "Impact Intensity Adjustment".
    How helpful was this information?

  • Will my tool operate if I use a lower flow rate than what would be considered optimum for the tool to operate?
    Yes, most tools have an optimal flow range, as long as the gallons per minute delivered to the tool is within this range the tool will work. However, please be award that the tool will run at a slower speed based on the flow rated delivered to the tool. Basically, the lower the gallons per minute the slower the tool will run.
    How helpful was this information?

  • Do any of the Stanley hydraulic tools ship full of hydraulic oil?
    No, but the factory normally will leave a little fluid inside the tool to help lubricate the internal components during storage.
