Milwaukee Reciprocating Saw 6538-21-B36B (2010) Heat Sink Replacement

Introducción

You can use this guide to replace a damaged heat sink on a Milwaukee Reciprocating Saw 6538-21-B36B (2010).

If you are noticing your Milwaukee Reciprocating Saw is constantly overheating leading to reduced performance or efficiency, then you could have a problem with the heat sync. The primary function of the heat sink is to transfer the heat generated by the motor, which allows for the motors internal component to continue to work without the heat. Having a non-functioning heat sink can shorten the lifespan of the saw, as continued use with overheating and additional strain can accelerated damage to the saw. The heat sink reduces the risk of safety hazard posed by overheating as the saw could smoke and catch fire, while also decreasing the maintenance needed for damage caused by overheating.

As always, remember to unplug the saw before any replacements.
