Drive Direction Change
The Stealth tools use interchangeable ratcheting links. Links are attached using a link pin. While the Stealth can be
used without a link pin it is always our recommendation to use a link pin whenever possible. For tightening, simply
engage the nut with the right side of the link facing down. For loosening, the left side of the link faces down.
Ratheting link can be detached from the Stealth power head by pulling the power head out while pressing the button
shown below.
The above diagram illustrates the direction the square drive should face for loosening
and tightening of a standard right hand fastener.

Setting Torque
Once the system is fully connected and the proper power supply is available, it is time to adjust the pump pressure to
the level needed on your job. When tightening, use the manufacturer’s specications to determine the torque value
which you will ultimately require.
Torque sequences may vary from plant to plant and even within individual plants, depending on the gasket material,
etc. Always abide by local procedures. The included torque chart is a guideline for comparison only and gives typi-
cal torque values specied for the most commonly encountered fasteners. Next, nd the pressure-torque conversion
table applicable to the tool which you intend to use.
An example of nding the desired torque required is as follows:
1. Assume you are going to use a HYTORC STEALTH tool to torque a 1-114” bolt to 1,265 ft lbs.
2. Start by referring to the proper torque chart shipped with your tool. Read straight down to the
number closest to 1,265 ft lbs, which in this case is 1,280 - about 1.5% over the targeted torque
value.
3. Now, using 1,280, read back to the left on that same line and read the pump pressure, under the
PSI column, 4,000 PSI.
4. To be technically correct, you should diminish that 4,000 PSI by 1.5% (to 3940), but 1,280 is well
within the tool’s +/- 3% accuracy range, so proceed to set 4,000 PSI on your pump’s regulator
valve.
