LITHIUM SERIES® II ELECTRIC TORQUE TOOL USER INTERFACE GUIDE
13
The fastener option displays fastener types and defines the direction of rotation. The user scrolls, highlights and selects
the desired fastener type. When the user returns to the Home Screen the abbreviation of the fastener type is displayed
on the screen. The fastener is set by default to RH, the most common type in practice. When the user selects another
fastener, this setting is saved in the tool until changed by the user. The fastener selection along with the position of the
directional switch determines which direction (CW or CCW) the motor must turn to tighten the fastener. The fastener
type also dictates which accessory is required for a bolting operation. The fastener type is abbreviated for display on the
Home Screen as shown in the table below.
For traditional RH or LH fasteners, the tool assumes use of reaction arms and displays a safety message, “Press any
button to start operation,” to keep the user’s hands away from any pinch point. For the HYTORC Washer (HWR, HWL) and
the HYTORC Nut (HN) a reaction arm is not required and the safety message is not displayed.
