00:00:00,000 --> 00:00:08,625
Special tools often used to maintain the Evolution Series locomotives include torque wrenches, adapters, and tensioning tools.

2
00:00:08,625 --> 00:00:17,708
The clicker torque wrench, sometimes called a digital wrench, works by preloading a "snap" mechanism with a spring to release at a specified torque.

3
00:00:17,708 --> 00:00:22,292
When the mechanism releases, the ratchet head makes a "click" noise.

4
00:00:22,292 --> 00:00:27,500
Rotating the handle until the desired torque is shown in the window sets the torque.

5
00:00:27,500 --> 00:00:33,083
Older clicker wrenches have a micrometer-style scale along the handle instead of a window.

6
00:00:33,083 --> 00:00:37,083
The ratchet head makes it easy to use in confined spaces.

7
00:00:37,083 --> 00:00:44,458
It is a good practice to set a clicker wrench to its lowest setting before putting it away to prevent the spring from permanently stretching.

8
00:00:44,458 --> 00:00:49,625
Avoid rough handling and dropping the torque wrench because it can damage the mechanism.

9
00:00:49,625 --> 00:00:56,167
Do not use the torque wrench to loosen fasteners; this may damage the calibration mechanism.

10
00:00:56,167 --> 00:01:01,500
Torque wrenches should be calibrated on a regular schedule depending on tool usage.
