A torque wrench isn't just a purchase, it's an investment. Here are 8 things to help you care for it.
1. The Right Drive
Always use the correct drive of torque wrench to suit the size of fastening you need to turn and how much torque you need to apply. The larger the drive the more torque can be applied.
2. Keep it Clean and Dry
After use always check that the tools are clean and dry before putting them away. This will help avoid problems such as corrosion and moving parts seizing or becoming tight.
3. Store it Properly
After use return the torque wrench setting to zero and store the tool in it's original case or a suitable case that will give adequate protection.
4. Check it Regularly
All torque wrenches need to be checked periodically and sometimes adjusted.
5. Be Careful
Torque wrenches are a measuring instrument and need to be treated with care - if you drop it you should get the calibration checked before using the torque wrench again.
6. Do Not Use Scaffolding Poles or Similar
If the fastening will not turn with the tools you are using you need to use a more powerful tool such as a larger tool or even an impact power tool. Do not use bars to increase the leverage - it is dangerous and can break the tool.
7. Do Not Use a Vehicle To Turn the Nut
Do not fix a torque wrench on to a fastening and then drive a vehicle to force it to turn - needless to say it is dangerous and can break the tools.
8. Do Not Use it as a Breaker Bar
Torque wrenches are for measuring and should not be used as a breaker bar to shift stubborn fastenings.
