What is the recommended air pressure to operate the air flushing feature on my SK58 Sinker Drill?
The minimum recommended air pressure is 75 PSI at 15 CFM. As the diver descends you will have to increase your psi to compensate for bottom pressure. Maximum operating pressure at the tool is 120 psi at 30 cfm.
Is it possible to order the SK58310 with a 7/8" neck rather then a 1" neck?
The SK8310 can not be ordered with the 7/8" neck. However, you can order the 7/8" neck as a spare part and make the change yourself if you have a trained technician on staff. The main disadvantage to going this route is the 7/8" neck part number 5195 is made of steel and will rust.
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.
What is the maximum depth I can operate my SK58 Hydraulic Sinker Drill?The maximum depth limit is 500 feet. A stock tool is able to operate at 100 feet without any modification. However, beyond the first 100 feet, for every additional 100 feet of water, the tool requires you to increase the accumulator PSI by an additional 40 PSI. The accumulator is pressurized to 600 psi standard.
