Motor Brushes
The electric motor uses 2 carbon "brushes" in order to function. The brushes wear as a result of use – this is
normal, and some tools may come with replacement brushes. If the brushes are allowed to wear past the
acceptable limit, the motor may produce less power, operate intermittently, or not operate at all. To check
brushes:
1. Use a coin or wide flat blade screwdriver to remove the brush cap (A).
2. Pull the brush (B) from the cavity and check the length of the carbon section (the "brush") (C). If the
brush is close to being fully worn, replace the brush – always replace both brushes at the same time.

3. Insert the brush into the cavity – the brush has 2 prongs on the electrical conductor (D) – ensure these
sit in the slots (E).
4. Re-install the brush cap (rotate right. Do not over-tighten).
