Tools and equipment list:

• ControlTech® Industrial Micro Torque Wrench - CTECHW2M1200(S)

https://b2b.snapon.com/productDetails/954783/2/888278

• Fastener Assembly plate
• Fasteners (bolts, washers, and nuts)
• 9/16” Wrench
• 9/16” Socket

Instructions:

1. Identify fasteners as specified
   1. Locate six (6) of each of the 3/8 x 16 bolts and nuts, and 12 washers located in the assembly area
2. Assemble fasteners in test plate

     b. Assemble (1) of each of the bolts, two (2) washers and nuts in each of the circular holes     

     3. Verify proper torque on torque instrument

WRENCH POWER ON SEQUENCE

Note: Do not turn on wrench while torque is applied, otherwise torque zero offset will be incorrect and wrench will indicate a torque reading when torque is released. If this occurs, re-zero wrench by momentarily pressing POWER button while wrench is on a stable surface with no torque applied.

• • Turn on Wrench

• • While holding wrench still, momentarily press POWER button.    Snap-on logo will be displayed followed by torque and angle re-zeroing screens (if angle mode has been previously selected).

    4. Torque Fasteners to 20 lb-ft and in a star pattern as specified 

TORQUE MODE

• • If needed - Set Target. Use UP/DOWN buttons to change TORQUE target value.

  • Select unites for measure. Repeatedly press UNITS button while on target TORQUE screen until desired units are displayed.

  • Apply TORQUE. Grasp center of handle and slowly apply torque to fastener until progress lights display green and a 1/2 second audible alert and handle vibration alerts you to stop.

  • Release TORQUE. Note peak TORQUE reading flashing on LCD display for 5 seconds.

PROGRESS LIGHTS

Yellow - First light indicates 40% of target torque or angle reached. Second indicates 60% of target reached. 

Green - Indicates target torque or angle reached.

Red - Indicates exceeded torque or angle target plus $% or exceeded maximum preset target.

    5. NOTIFY THE JUDGES UPON COMPLETION OF THE            ASSIGNMENT.

Scoring:

Scores will be calculated according to the AMC score sheet. Additional penalties may be assessed for improper assembly of a fastener, improper inputting of torque settings into the torque instrument, and/or application of torque to fastener.
