5. Operating Instructions
5.1. Powering On/Off
Press the power button (refer to the tool's display for exact location) to turn the screwdriver on. The display will illuminate. To turn off, press and hold the power button, or the tool may automatically shut off after a period of inactivity to conserve battery.
5.2. Setting Torque Value
- With the screwdriver powered on, use the designated up/down or +/- buttons to adjust the desired torque value.
- The display will show the current torque setting in in.-lbs.
- Ensure the desired torque value is within the tool's operating range of 1.77 to 35.39 in.-lbs.
5.3. Applying Torque
- Place the installed bit onto the fastener head.
- Apply steady, even pressure and rotate the screwdriver in the desired direction (CW for tightening, CCW for loosening).
- The screwdriver will provide an audible click and/or visual indication (e.g., LED light, display change) when the preset torque value is reached.
- Stop applying force immediately once the indication occurs to prevent over-torquing.
5.4. Rotation Direction (CW/CCW)
The Westward 6PAF5 supports both clockwise (CW) and counter-clockwise (CCW) rotation. The accuracy specifications differ slightly between directions: +/-2.5% for CW and +/-3.5% for CCW. Always verify the correct rotation direction for your application.
6. Maintenance
6.1. Cleaning
Wipe the tool with a clean, dry cloth after each use. Do not use abrasive cleaners or solvents, as these can damage the housing and electronic components.
6.2. Storage
Store the torque screwdriver in its blow mold case when not in use. Keep it in a dry, temperature-controlled environment. Remove the AAA battery if the tool will not be used for an extended period to prevent battery leakage.
