# Troubleshooting and Service

This section provides assistance in troubleshooting problems, should they arise, and contains information to help you maintain and service the product.

# Overheated Tool

With proper adjustment the tool can handle any normal line jobs that an operator sustains. What can cause overheating are combinations of some factors: torque above rated, too low speed, too long ramp time (motor has to give high torque for a long time), very high prevailing torque, very soft joints, short cycle time. To correct, look over speed, ramp time, tightening strategy. One stage and Ergoramp are most heat conserving when applicable. Please refer to the User Guide of your POWER FOCUS. If the above corrections are not enough, choose a tool of the next higher capacity.

# Removal of Jammed Screws

Follow the below troubleshooting steps to remove the Jammed Screws:

- Never use excessive force for removing the jammed screws.

- By opening the Alignment Jaws or lifting the Swivel Arm up, the jammed screws comes out easily from the feeding head.
