# Troubleshooting Guide

Problem | Reason | Action
--- | --- | ---
Tool does not shut off or tightening time is too long. | Target torque close to maximum torque of the tool. | Chose a bigger tool with more power.
| Worn extension or socket/bits. | Check the extension and socket/bits.
| Incorrect oil level in the Pulse unit. | Adjust the oil level or refill the oil.
| The joint is too soft for the tool. | Choose a bigger tool with more power or increase pulse energy.
| Worn parts in the Pulse unit. | Inspect and replace any worn parts.
| The yield point of the joint is reached. | Check the joint specification.
Inconsistent shut off or insufficient accuracy. | The target torque is not within the tool specification. | Change to a different tool size.
| Extension is too long. | Change to shorter extension.
| Worn extension or socket/bits. | Replace the extension and socket/bits.
| Incorrect oil level in the Pulse unit. | Adjust the oil level or refill the oil.
| The joint is too stiff. | Choose a smaller tool or decrease pulse energy.
If the tool becomes very hot. | Very high prevailing torque. | Change to a different tool size.
| Very soft joints. | Change to a different tool size.
| High cycle rate. | Change to a different tool size.
