FAQ's

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.

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.
